A comparison of the goitred gazelle and the springbok

Two gazelles, the goitred gazelle (Gazella subgutturosa) of the Iranian region and the springbok (Antidorcas marsupialis) of South Africa, make for an obvious comparison because they live in similar semi-deserts and grasslands in opposite hemispheres. Neither environment offers hiding places. However, the main difference in adaptive colouration is that the goitred gazelle tends to blend into its surroundings whereas the springbok tends to stand out from its surroundings.

What makes the springbok conspicuous even at a distance is its bold dark flank-band offset by white highlights on the face, rump, upper legs and upper flanks. In the goitred gazelle the basic pattern is similar but so toned down that it resembles camouflage.

Both species display to scanning predators by stotting, but here the differences become even more graphic. The goitred gazelle merely bounces up and down while erecting a black tail. By contrast the springbok has the most extreme bouncing performance seen in any antelope, blazening an uniquely extended white crest which is normally hidden by folds of skin running along the rump.

Perhaps these differences arise in the different regimes of natural predation in the Iranian region and South Africa. Here, the counterintuitive principle is: the more intense the predation, the more adaptively conspicuous the gazelle evolves to be.

In both regions, natural predators included the cheetah (Acinonyx jubatus), the spotted hyena (Crocuta crocuta), and large cursorial canids (wolf vs painted hunting dog) which scanned the groups of gazelles by day and carefully chose the least-fit member as quarry. This pre-chase scrutiny created some selective pressure for self-advertisement, or 'showing off' instead of hiding.

A crucial difference was that the northern species was the only wild ruminant in most of its habitat, whereas the southern species always existed with the red hartebeest (Alcelaphus caama), the blesbok (Damaliscus pygargus phillipsi) and/or the black wildebeest (Connochaetes gnou). The greater reliability of prey in South Africa would have supported a boosted density of the crucial predators, and thus a boosted rate at which the groups of prey animals were spotted by the painted hunting dog. Arguably an evolutionary tipping point was reached, beyond which the overall colouration of adults flipped from concealing to revealing.

The best chance for each individual of the springbok is not to attempt to hide, either in the landscape or among the group. Instead it is to advertise itself as strikingly as it can, disqualifying itself as being worth chasing in the First place. In the case of the goitred gazelle as in most other antelopes, encounters with predators remained infrequent enough that it remained worthwhile to hedge bets rather than committing to advertisement. And this rationale might also explain why both the blesbok and the black wildebeest also have colouration more conspicuous than in their close relatives.

Thanks for participating in City Nature Challenge 2021

Thanks, everyone, for adding your observations and IDs to CNC 2021. We ended up with 1153 observations and 365 species, from 58 observers and 158 identifiers. Not too shabby, considering just about no leaves or flowers were out yet, and it was freezing most nights. One of our observations, a Peregrine Falcon by @gracekwong, was among about a dozen observations that were highlighted in the official worldwide results. Some of you got pretty creative; a woolly bear moth was identified based on a cocoon, and a few plants were observed and identified based on last year's stalks and leaves.
Overall, Canada had 49778 observations and 3263 species, and worldwide there were 1.2 million observations and 45000 species, from 419 participating cities. We were the farthest north city in North America, and it's challenging to find things here so early in the season. But there's another bioblitz coming up - the Edmonton BiodiverCity Challenge 2021, from June 10-13. It will be much easier to find things then, so I hope you'll join us! It's the same metro area, and the same ground rules. You can find the project here:

cheers,
Greg Pohl - metro Edmonton biodiversity coordinator

Our Mob

Id like to acknowledge the Bunurong and the land I've lived my whole life on, pay respect to elders from the past, present and emerging. The land of the Koem. (Kangaroo, known for its big boomers as the big males were called by the colonisers)

In May 2018 Virginia and I (Mark) started counting and recording our local mob. We were curious about seasonal fluctuations in numbers, short term variations and particularly long term trends.

So three years of records have been transcribed from a note pad to spreadsheets. One day we will upload that to Inaturalist along with other peoples historical data. Exactly how and when can be determined by our Wildlife Action Group so keep your old records no matter what form they are in. We are using Inaturalist now for all new entries and am loving the application and its features. Record any species you can, join the Mornington Peninsula Biodiversity Project as well as the Mornington Peninsula Kangaroo Count

Our mob is on private land that is not ours, it's currently owned by someone who seems happy to have the mob move through the landscape as they have done for millennia. Our small bushland property and the land the mob congregates on are adjacent to Greens Bush. Of course we get visited by a small number of females and their joeys and the occasional male or two courting a female. Also we had the amazing experience of being involved in the soft release of several kangaroos that had been rescued by wildlife carers, this young mini mob eventually joined our local mob and we still get visits.

Our mob counting for three years now has fluctuated dramatically, after counting a few times, particularly with another person at first to corroborate numbers, you get better and reasonably accurate. We realised that guessing would overestimate numbers, a guess would be say a mob of 100, an actual count would reveal about 45. So our mob has peaked at 70 in October 2020 and 70 again in November 2020. Looking through the numbers 50 seems to be the peak mob gathering and often the number is about a dozen or so.

We count several times a week from our car whenever we go to and from our property. Counting would be best at dawn and dusk at regular places and times in relation to sunrise and sunset. But any observation is better than none. Using Inaturalist means observations can be filtered for times, seasons and locations. This information can then be compared to weather information, landscape changes and other management practices.

Get out and count your mob, wouldn't we all love to know what was happening historically. Ive just finished reading 'I Succeeded Once' The Aboriginal Protectorate on the Mornington Peninsula, 1839-1840 Marie Hansen Fels. Don't underestimate the value of records, they can be all we have to remember what once was and what could be.

City Nature Challenge - Not to be missed!- Lorraine Phelan

My family announced that they were going away for the weekend of the City Nature Challenge. Did I want to join them? No way, Jose!
So I had four days to myself with no commitments, no meals to prepare, no clocks to watch.

I had a wonderful time photographing (mainly plants) in the Shelford area, the Brisbane Ranges, Forrest and Stevenson’s Falls and, on Monday, the Anglesea heath. I set up the moth sheet in my back yard. Each evening I sat with my feet up while I sorted through my photos, editing and uploading. I had my reference books out all week while I admired everyone else’s uploads and tried to help with the identification when I could.

My best finds? A stunningly beautiful Red-banded Greenhood, a Smooth Solenogyne, and two Threatened plant species, Button Wrinklwort and Spiny Rice-flower, growing next to each other in the grassland.

From the first photo on iNaturalist, a Welcome Swallow uploaded by Deborah, to the last it was all fun. And exhausting.

May 2nd Near Cloverfield Farm in Colchester, VT

On a breezy, sunny afternoon at around 3:00 pm, I sat in a field near Cloverfield Farm in Colchester, Vermont, waiting to see what birds I would see buzzing by me. It was about 65 degrees on May 2nd and there were hardly any clouds in the sky. I sat on the edge of a forest near a small swampy wetland where there seemed to be dozens of Red-winged Blackbirds nesting in the reeds and trees surrounding. I was able to hear many more birds than I could see, for many of them were in the dense reeds and understory where the wetland met the forest. The only birds that seemed to come near me were the Common Grackles and American Robins. I heard a Belted Kingfisher calling to another somewhere in the wetland, but did not see it. I assume it was a mating pair, one on a nest somewhere in a little bank near the water and the other scouting out around the edge of the swamp.

I also noticed a couple Blue Jays chasing around European Starlings in some of the trees on the edge of the field, fiercely defending their territory and likely preparing for their offspring. While these blue Jays were defending their territory as if it was a hot location, I'm not sure it was the best place for them to be brooding in comparison to other locations nearby and may have been a poor territory choice. I say this knowing how often I see Red-Tailed Hawks and have heard owls in the area, in addition to simply how busy this area is full of birds. There might be many resources in this location for them, but the competition for those resources is certainly high. These Blue Jays were likely expending a lot of energy and were in great shape regarding their fitness in acquiring resources. Based on how tough these Blue Jays looked while fighting off birds that didn't seem like too much of a threat, I have a feeling they will be mostly ok.

I noticed the Red-winged Blackbirds spending a lot of their time in the reeds and in the marshy vegetation at the edge of the woods. I assume many of them were nesting there, defending and spending time keeping an eye on all the local happenings. They mostly build their nests out of reeds or marsh grasses that die or dry out, which seem to be sturdy and easy to carry.

Before I left this little spot, I drew a "sound map" of myself and the proximity (not to scale) of me to the birds that I heard around me. As you can see, there were birds on all sides of me almost at all times, but the Red-Winged Blackbirds did not move too much from the marshy part. I tried to roughly notate the songs and calls of each bird as they compared to one another with different musical notes corresponding to their rough rhythm. The quality of their sound is vaguely depicted through the illustration.

A Bright Future

Today I had the opportunity to walk and make iNat observations with a group of newly minted grads of the UVM Rubenstein School of Environment and Natural Resources. After a pandemic-restricted semester of masks and remote meetings the team's diligent work assisting the Jericho Conservation Commission with a mapping project as part of their course 'Environmental Problem Solving' is finally complete.

On this beautiful May day they were finally able to visit Jericho and see first-hand the beautiful place that we work so hard to protect and how their work contributes directly to that effort. Their enthusiasm for each bud and birdsong was contagious and it renews my hope for the future to see that there are such talented people venturing into the ever-important work of conservation.
Best wishes for your future endeavors to Dayna, Flynn, Liz, Lucca, Maddie, and Zoe - "Team Jericho".

Help document Oregon's native turtles

There are two species of freshwater turtles native to Oregon: the western pond turtle and the western painted turtle. Warm spring weather is a perfect time to spot Oregon's native turtles basking on logs or rocks in their aquatic habitats. This is the breeding season for these turtles, so you may see female turtles emerging from ponds to find a spot where they will dig their nests and lay their eggs. Be on the lookout for turtles crossing the road; sometimes females will travel a long distance from ponds to deposit their eggs.

Both of native turtle species are Oregon Conservation Strategy Species, and face a wide variety of conservation threats, including habitat loss and invasive species. Biologists in Oregon, Washington, and California have been working to map the current distribution of western pond turtles, and need your help! Have you seen turtles basking on a log in a pond or a turtle digging a nest on land? Snap a picture from a safe distance away, document the location, and add it to our project! You can also visit the iNaturalist project Western Pond Turtles in Oregon . Data collected describing the current distribution of this species helps biologists identify priority conservation areas that will help ensure the long term conservation of the species.

To ensure that your data can be used, make sure to add your data to the Oregon Wildlife Conservation project, or under project membership select
the option that allows private/obscured observation coordinates visible to project curators.

EcoQuestions with Kara Barron

Hi Neighborhood Naturalists,

If you missed EcoQuestions with Kara Barron, it is now up on our YouTube channel! See the Recording.

Kara discussed how plant communities respond to wildfire, as well as how some individual plants respond and how a future with more frequent wildfires will alter the plant community composition.

Kara is the Science and Outreach Manager at the Gila Watershed Partnership in Safford, AZ. As part of her position, she manages the seed collection program that supports restoration projects along the Upper Gila River. She graduated from ASU in 2018 with a master’s degree in Plant Biology and Conservation where she studied the impact of wildfire and restoration on plant community composition of the Arizona Upland subdivision of the Sonoran Desert.

It has been fun watching you learn

Students,

It has been a joy watching you learn about the wildlife around you. Over the last few months, I have seen many of you become more knowledgeable about the trees and animals you encounter each day. In class most of you can now call organisms by their common names, identify the scientific names of organisms with the help of iNaturalist, and recognize species previously unknown to you. You have made me a proud teacher. I hope that you enjoy your summer 7th graders . . . or should I say rising 8th graders? The last day to submit observations is May 19, 2021, for course credit. I will leave the bio blitz open indefinitely for those of you who want to continue your studies of nature.

Bio Blitz Thanks!

Hello iNatters,

Thanks to all of those who participated in our annual bioblitz. This year we reached a new level of participation! You observed over 300 different species -- we couldn't have done it without you. This information is super helpful to us. Observations help us identify invasive plants at sites and tell us what species are attracted to our restoration sites. This information helps us to get a better idea of all of the species found in our watershed However, the fun does not stop there! This year we are encouraging you to visit all of our restoration sites throughout the watershed and submit observations. Project sites include: Abington Friends School, Rock Lane Park, McKinley Elementary School, Ethel Jordan Park, Abington Junior High School and the Conklin pool.

Happy iNatting,
The TTF Team

Extra Credit

Nicholas Frank
Extra Credit
Date: 5/08/21
Start Time: 12:00pm
End Time: 2:00 pm
Location: Great Swamp National Wildlife Refuge
Weather: Mid 50's, partly cloudy, slight breeze
Habitats: Hardwood Forest (mostly Poplars, Oaks, Birches, Maples), Open Field, Swamp/Bog

For the extra credit assignment, I took my childhood friend Joe Purce on his first birding excursion. Joe enjoys outdoor activities like hiking and works at REI so getting him to go outside was not much of an issue, but I don't think he would have gone birding with me unless I told him it was for my extra credit. We went to a place we had both been as children for both school and cub scout field trips, the Great Swamp National Wildlife Refuge.

Although he did become a little bored towards the end, he said he found it interesting how many distinct songs there were for birds that he never listened too. Joe always knew there were different songs and calls for different birds but never noticed the complexity of them until now. I believe "meowing" of the Gray Catbird is what really caught Joe's attention. He enjoyed taking the time to walk around and enjoy the wildlife in a new way. Joe also found it interesting when I told him how to identify the difference between a Hairy and Downy Woodpecker. Joe said he would never be able to tell the difference if he saw one or the other on it's own but found it interesting that such a subtle differences are used to distinguish one species from the other. Overall I think he enjoyed his first birding excursion although I am not sure if he will go again anytime soon.

Primer registro de Crocodylus acutus en el 2021

Tras varios meses de ausencia, el Crocodylus acutus ha vuelto al Refugio de Vida Silvestre Manglares El Morro. En este año los pescadores han estado reportando avistamiento de este animal desde el mes de abril en el estero Ayalán. El 11 de mayo a las 14:30, tras varias horas de búsqueda lo hemos encontrado en la misma zona que se lo encontraba el año pasado.

El cocodrilo encontrado mide aproximadamente 1.5 metros, muestra un comportamiento activo, evade a la embarcación, nada con rumbo hacia boca del estero ayalán, en su trayectoria se sumerge y vuelve a emerger en varias oportunidades, se cruza de una orilla a otra en el estero. se acercó a un bajo de sedimento donde había muchas aves, no se inhibe frente al paso rápido de una embarcación.

Se calcula que durante todo el transcurso de la observación el cocodrilo se desplaza aproximadamente 818 metros.

El año pasado también se lo registro en estos meses, en la misma zona. Esto nos indica que el cocodrilo esta migrando y que para estos meses llega en busca de algo o para actividades especificas, tal vez para reproducción, anidación o alimentación.

Goździkowe Bagno

Po wierceniach sosen w nadl. Celestynów wybraliśmy się z @marcinklisz - już rekreacyjnie - na Goździkowe Bagno. Bardzo podobają mi się te okolice, lasy zupełnie inne niż po „naszej” stronie Wisły.
Botaniczną przyjemność zapewniły dziś: siódmaczek leśny (kilka w fazie kwitnienia), żurawina (nareszcie ją znalazłam!) oraz nowy gatunek fiołka, który zidentyfikowałam w domu jako fiołek błotny (nie mylić z fiołkami: bagiennym, mokradłowym i torfowym).
Oczywiście torfowce, bagno zwyczajne, widłaki... cała ta bagienna menażeria. ;)

Artifact or Garbage?

I came across this burnt out roadster sitting a good ways back in the woods about 200' in elevation above Eight Mile Road. I don't really think a burnt out roadster belongs in the woods. At the same time, what 12 year old kid wouldn't be thrilled to find this? My personal opinion is that even fairly recent cultural artifacts like this one add something to the mystery of the place. I'd be in favor of leaving it there. Besides, I can't imagine what it would take to drag it out. I took a picture with my Nav Cam in case other people with more formal responsibility for this area come to a different conclusion and decide to remove it. The coordinates are contained in the upper left of the image.

This one seems a little more obvious. This is most likely the lead and acid filled battery out of the roadster. I'd probably have lugged this down the hill today but I was too interested in seeing the plant community at this woodlot. This was the start of my walk so I'll probably be back to haul off the battery at some point in the future.

These seem like a toss up. It's kinda cool seeing a bucket that isn't orange, plastic, and emblazoned with Depot branding. The glass probably isn't old enough to add anything. I still think some kid would like it but there's probably too much risk that an older kid would smash it against a rock. I'd probably go with "remove the glass, leave the bucket"... but since it's a tweener, I left them both.

Next to the roadster were a bunch of "white goods". That's recycling parlance for appliances. With the price of shred, these would be worth dragging down to Cohen for a sweet payday but it'd still never cover the cost of the labor. Unlike the roadster, they don't add much to the ambiance. Their removal is above my pay grade so I'll leave them be.

This is either a dilapidated shed or an outhouse, I'm not sure which. I view this as "ruins". It adds something to come across things like this on a walk in the woods. It makes you imagine how the property was used before and forces you to consider the regeneration of the forest.

I'm pretty sure that's an enamel chamber pot in the foreground. So maybe it was an outhouse. I dunno, I'm not an expert on chamber pots.

Next post will be about trees and plants at this location but I felt like some of these pictures were worth sharing. When it's decided which things should stay and which things should go, I'd be happy to help remove what is deemed to be garbage. If a volunteer trail is created that enters this greenspace, it should take hikers close enough to the roadster for others to discover it. I almost feel bad revealing its location. It was fun to come across. Others should get to "discover" it too.

Another Extension!

Hello everyone!
We’ve decided to extend the end date for the BioBlitz again. The weather just doesn’t seem to want to cooperate with our plans! We’ll send out another announcement if we have to extend the BioBlitz again or if the cicadas start emerging. Hopefully we’ll start seeing some cicadas soon!

Best,
The Indiana Cicada Fest Team

Экватор Конкурса!

Уважаемые коллеги и друзья (@chapaeva, @fedascheva, @ragazzascienza, @marmakeeva, @anna-sinichkina, @mariasemova, @ezevika2007, @nastyariabova05, @juliya13, @kakushkina, @annvesna, @nadezhda12, @viktoriyath, @sasha2726, @kireeva_natalia, @polinamoiseeva13)!

Сегодня 13 мая 2021 года, и прошло ровно половина времени нашего Конкурса! мы можем подвести промежуточные итоги и результаты проведения конкурса. Однако перед этим мы хотели бы напомнить Вам о Правилах Конкурса, нарушения которых нами отмечены в ходе первой недели проведения Конкурса.

НЕ ДОПУСКАЕТСЯ создание дублей одних и тех же наблюдений. ЧТО ЭТО ЗНАЧИТ? Если Вы фотографируете одно растение (один вид) в одном местонахождении в одно и то же время (например, на одной полянке), то НЕЛЬЗЯ эти фотографии представлять как разные наблюдения. Объединяйте их в одно наблюдение с несколькими фото!

КУЛЬТИВИРУЕМЫЕ РАСТЕНИЯ (которые посажены человеком) в рамках Конкурса НЕ УЧИТЫВАЮТСЯ при подсчете финального количества наблюдений. Чтобы не оставалось сомнений в том, культурное растение или выросло вне места культивирования, фотографируйте не только растение, а и общий вид местообитания.

ОБЯЗАТЕЛЬНО реагируйте на комментарии и просьбы Организаторов Конкурса, направленные Вам в комментариях к наблюдениям и в сообщениях (видны в компьютерной версии). Как было указано в Положении к Конкурсу, за систематическое отсутствие реакции на комментарии и, например, просьбы удалить дубли наблюдений, участник может быть исключен из состава конкурсантов.

 

Итак, после первых семи дней Конкурса "В поисках растений-2021" мы можем зафиксировать статистику для истории нашего проекта на сегодняшний день: 612 наблюдений на 174 вида наш проект включает 13 марта 2021 г. в 19:15 MSK.

Статистика проекта: 612 наблюдений - 174 вида - 40 экспертов - 12 наблюдателей.

Ниже приводим статистику для участников каждой из двух категорий участников Конкурса - от 12 до 17 и от 18 и старше.

ВАЖНОЕ ПРЕДУПРЕЖДЕНИЕ! Дорогие участники, когда фотографируете растение, будьте осторожны и внимательны, когда его трогаете руками! Кроме широко известного борщевика Сосновского могут встретиться вех ядовитый или болиголов пятнистый (похожие на морковь), которые чрезвычайно и СМЕРТЕЛЬНО ядовиты! Поэтому будьте осторожны!

 

Желаем всем Вам удачи и успехов в дальнейшем ходе Конкурса!

Improving your iNat fungi observations

We are starting to see Spring fungi in abundance thanks to the rain! One great way to improve your observations is to use iNaturalist to locate flushes of fungi that others have recently found so you can get first-hand experience with how these things can appear. This iNat observation is on a hillside overlooking Crescent Water (right next to the weather station) that is showing a large flush with couple of coprinoid species and what I believe are some psathyrella. I've created this step-by-step guide to locating fungi in the field using your phone.

I'm also seeing a few observations that are less thorough than we'd like, and my sense is that folks are still new to all this. So I'm putting this link to a document we developed for the Mycoblitz that summarizes guidelines for good quality observations that we can include in the FunDiS project.
