What do you picture when you think of the impact of climate change on Earth's species? #climate #endangered #ph260720
I'm going to guess that many of you picture something like this when you think climate change. And it's true and it's heartbreaking that climate change is endangering this little guy, but too often the conversation ends there. #polarbears #ph260720
Climate change isn't just threatening exotic species in far-off places. It's hurting human health. When we think of climate change, why don't we think of wildfires polluting our air or climate refugees being forced to leave home? #refugees #ph260720

"Stranded turtle bones reveal divergent life-history characteristics for critically #endangered #hawksbill #seaturtles inhabiting US waters"

Sometimes🐢wash ashore (strand) dead. Let's talk about what their🦴can tell us about their past life. #TurtleTuesday
2/7
Global #hawksbill pops. declined >80% in the past 100yr. Study of immature🐢was recently identified as🌎priority. Hawksbills typically inhabit🌴coral reefs but juveniles also forage in subtropical US waters➡️Texas & Florida. Yet, little is known about their ecology in the US
3/7
To address this knowledge gap, we studied the growth layers, #stableisotopes & #traceelements in the🦴of 94 US-stranded turtles (1989–2012). This led to new data on:
1⃣ stage duration (oceanic vs. neritic)
2⃣ size-at-age relationships
3⃣ age-at-maturation
4⃣ growth rates

Spectacle Monkey's population is increasing in Tripura.

A thread. Image
1. It is also known as dusky leaf monkey, spectacled langur.

2. It has a white round patch around its eyes and looks as if it is wearing a spectacle, and thus called “spectacle monkey.” It is also known as "chosma bandor" in the local dialect. Image
3. It is a species of primate in the family #Cercopithecidae.

4. It occurs in peninsular #Malaysia, #Myanmar, and #Thailand. It is spotted in northeastern states especially in #Tripura, Assam, and Mizoram along with Chittagong hill tracts of #Bangladesh, in parts of China. Image

Getting lost in the crowd can be a problem when you’re an #endangered sea lion pup. Taronga behavioural ecologist @PitcherBen & collaborators are decoding #Australian #sealion communication to understand how mothers and pups recognise each other in a busy colony #ScienceWeek
Australian sea lions use a combination of sound, sight and smell to communicate and recognise their pups. Mothers can use the size and colour patterns in pup coats to help located their offspring in a colony royalsocietypublishing.org/doi/pdf/10.109… @RSocPublishing #AnimalCommunication
Smell is critical to recognition. Mums will smell pups they encounter while searching the colony to confirm which pup is their own offspring. Each sea lion has a unique smell and mums learn the odour of their pup sciencedirect.com/science/articl… #AnimalCommunication

If story of #Sinauli shocked u yesterday, wait till u read about #Rakhigarhi ,as accepted internationally the #Oldest & #largest civilization to be found in world!
This will also answer the Q about whether #NoAryan theory has been proved or not & role of Modi govt

In the budget of Feb 2020, @nsitharaman announced 5 archaeological sites located across five states to be developed with on-site museums
Rakhigarhi in Haryana, Hastinapur in Uttar Pradesh, Sivasagar in Assam, Dholavira in Gujarat and Adichanallur in TN
Found in 2020?
Ans No

, #Hastinapur was initially found in #1952
#Rakhigarhi 1963
Dr. Lal who was incharge of excavation believed that these couldn't just be related to #Mahabharata but can successfully dispel the myth of #Aryan invasion !
Dr. Lal believed that these could have belonged to 800 BC

Check out our latest preprint: the relevance of pedigrees in the conservation genomics era bit.ly/3wCO7DH. TLDR: it’s not either/or when it comes to #pedigrees & #genomics. Having both helps researchers address more conservation questions than one data set alone. 🧵 1/10
Conservation #genetics 🧬 has developed a substantive toolbox 🔧 to inform species management. While much discussion has been dedicated towards genomic advances, there remains one long-standing tool in #ConGen that is often overlooked: the pedigree. 2/10
Pedigrees have been used to understand and manage diversity in threatened populations for decades. But, caveats like assumed founder relatedness, missing data, and errors can make them tricky to use. See Forsdick et al (ecoevorxiv.org/7bnjw/) for more. 3/10

An unpopular thread on B.C.s raging forest fires.

Much of B.C.'s interior is a fire maintained ecosystem.

Tree ring research shows fire intervals of 5-20 years in much of it which fire suppression starting 100 years ago and getting really good starting in the 1950s.

1/n
Our plants, trees and wildlife all evolved with fire. Fire rejuvenates grasslands and plant communities and is an essential part of functioning and productive habitat for native species such as , moose, elk, mule deer and sheep, plus the growing list of #endangered species.

2/n
A number of these populations are in decline/at record lows; fire suppression plays a central role. Fire suppression results in more fuels on the forest floor and ladder fuels from young trees growing in areas where they shouldn't be, putting people and biodiversity at risk.

Would reducing red meat consumption in Canada do more hard than good? A thread: (1/13)
@epicurious, @FoodSystems, @EATforum – you’ve heard it multiple places: ‘We must reduce meat consumption for climate change, the environment, to reduce our dietary carbon footprints.’ However, what could the implications of this be for #Canada? (2/13)
In a recent @CBCNews article, a researcher suggested that reducing beef consumption by 25% would result in a reduction of livestock related emissions of 10%. Sounds good, but… (3/13)

🦈WHALE SHARK🦈
#Whalesharks are the largest fish in the sea, reaching almost 19m! They are one of only three filter-feeding shark species, the others being the megamouth shark and basking shark. They use gill filters to catch plankton, jellies and small fish. #Sharktober
We usually think of filter-feeding as happening automatically as the animal swims with its mouth open, but whale sharks are actually very active hunters. They use active suction to catch small animals near the water's surface. #Sharktober #whaleshark
#Whalesharks typically prefer tropical and temperate open oceans, but their slow migrations often bring them near shore to feed. These aggregation sites, including #SouthAfrica's southern coast, often benefit greatly from #ecotourism as a result of these beautiful visitors.

Welcome back to another episode of the #WildAboutFacts series. Today, we are taking over your feed with pictures and #trivia of one of the most alluring creatures from the #wild, the #RedPanda.

Join us, share your #photographs of the #Firefox of the #Himalayas.

#WildAboutFacts

Its distinctive fur has earned this species monikers such as #Firefox, Firecat, or Fire-coloured Cat. Arguably, the #RedPanda is the only true #Panda, as the #GiantPanda, which is believed to be closely related, belongs to the #bear family.

#WildAboutFacts

Around half of the #RedPanda’s natural habitat lies in the Eastern #Himalayas#Nepal, #Sikkim, northern #WestBengal, #Bhutan, and #ArunachalPradesh.

Its remaining home is in northern #Myanmar and a few provinces of central #China.

⬆️ benefits from wildlife = improved views & actions toward wildlife, right?

Common assumption for #CommunityBasedConservation, but not many studies that assess these relationships

We 👀 at these links using the case of #Endangered reticulated 🦒 in #Kenya 🇰🇪
2/6 There are a # of benefits/costs, tangible/intangible, connected to wildlife conservation

In any community, there’s a diversity of ability/access/motivations to participate in conservation

We 👀 at perceptions of benefits, attitudes toward #giraffe, past 🦒 meat consumption
3/6 We asked:

🦒 Y/N for different types of benefits – two types ($ from tourism & job in cons/tourism) coded as cons benefits
🦒 Attitude toward giraffe on 5p scale
🦒 Most recent time of giraffe meat/part use – re-coded into never/1+ year/within last year

We are excited to share our pub in #EvolutionaryApplications bit.ly/2GH3tzr comparing relatedness estimates for pairing recommendations in critically #endangered #birds from #Aotearoa #NZ 🇳🇿. See this #SciComm 🧵 for more! #Conservation #Genomics #ConGen #ConSERTeam 1/13
Around the 🌏, #conservation breeding programmes strategically pair the least related individuals to enhance recovery. This is like #Tinder for threatened species, only more information goes into pairing than swiping ⬅️ or ➡️. See my #3MT for more! 2/13

It’s important to get the relatedness value right for pairing, because mating between close relatives can result in negative fitness consequences, like ⬇️ hatching success 🐣(see bit.ly/3b4IILO). 3/13

Thing I’ve been hearing a lot recently: “Real Time Fish monitoring should dictate when the CVP & SWP export pumps are turned off to protect #endangeredspecies. See fish-pump off...no fish-pump on”.

There is *so* much wrong with this, it will require a #thread to unpack.
2a) Real time monitoring is not individual surveillance. Ecological monitoring will always miss individuals, esp. for rare species. (ie, we call it “sampling” & use statistics).

Monitoring will likely miss rare species & the early/late migrants that populations depend on.
2b) This point — the need to maintain life history diversity to prevent declines — can’t be overstated. Just protecting a narrow slice of these species’ diversity is a recipe for further decline & loss of resilience.
