We tend to talk about bats as if they were all identical in appearance, habitat, and habits. But that’s far from the truth.

@Cori_Lausen, @wcscanadabats director, talks about 4⃣ Western Canadian #bats in @ecofriendlywest: tinyurl.com/4prrnkk2 🧵
1⃣. Spotted Bats have black fur with 3 large white spots on their rump and shoulders as well as smaller white patches at the base of their pink ears, which are as long as their body. They are found in dry desert regions of the southern #Okanagan and are extremely rare. (cont'd)
Unlike many other bats, the Spotted Bats’ echolocation sounds can be picked up by the human ear as they are typically producing sounds as low as 7-12 kilohertz that sound like a series of clicks.

*Tamanaviruses* - a primer (medium thread)
(1) Tamana bat virus (TABV) is a highly divergent #flavivirus that was isolated in 1974, from a bat trapped at the exit of Tamana cave, on the North slope of Trinidad's Mount Tamana. Image
(2) TABV was identified at the Trinidad Regional #Virus Laboratory (TRVL) as part of a post-war virus discovery effort lead by the Rockefeller Foundation.

The #Tamana cave system comprises several large limestone caverns and is a roost for several species of bat. Image
(3) Millions of bats fly out of Tamana cave exits to feed at dusk, making for an impressive spectacle.

Researchers at TRVL trapped #bats at cave exits, took samples from these bats and attempted to cultivate viruses. Image

⬆️🌡️in #winters are affecting many taxa worldwide, such as #bats. Hibernating🦇might be forced to arouse & find💧&🦟in the future. But, do bats fly out of the roost during❄️season now? When? How much? And where? Are #wetlands important during this period? Let's see👇 pic: Adrià López-Baucells
2/5 #CWTC21
To understand 🦇#behaviour during ❄️we used #batacoustics and weather information in #wetlands, #ricepaddies, 🌆 areas, & #saltmarshes from one of the biggest Deltas in Western Europe (Ebro Delta). @PDE @parcscat @govern @HumedalesDelta @ecologistescat @FBiodiversidad
3/5 #CWTC21
Results:
1- The most recorded #batspecies was #pipistrelluspygmaeus
2- 🦇were active during the 83% of our total recorded nights (469) mainly using #wetlands & 🌆areas
3- We found a threshold value that triggered #batarousals ->11ºC during❄️nights

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

La siguiente pandemia 🦠🤒

La mayoría de las enfermedades infecciosas nuevas surgen por el contacto entre animales y humanos

Es importante conocer la cantidad de patógenos transmitidos por esta vía, especialmente #virus y así poder limitar el contacto con ellos

🧵👇🏼

El probable origen del #SARSCoV2 en un mercado de animales ha puesto al descubierto una vez más, el papel que juega el comercio de #VidaSilvestre sobre posibles zoonosis, es decir, enfermedades transmitidas de animales al ser humano 🦆➡️👵🏻

2/10
Otra #pandemia de origen zoonotico es la de #VIH

Este #virus se ha transmitido en múltiples ocasiones desde otros primates hacia el ser humano debido al contacto muy probablemente por la caza para obtener carne y para comerciar como mascotas exóticas 🐒

Aaaand it's out! New paper alert, today in @PNASNews #Bats #Echolocation #Bioacoustics

We (@YovelBatLab) found that echolocating bats rely on an innate reference to the speed of sound, and likely encode the world in terms of time, not distance.

🧵1/n

pnas.org/content/118/19…
Bats' brains calculate the distance to objects by the delay between an emitted pulse and the reception of its returning echo. For that calculation to work, there must be a reference to the speed of sound, and since this speed changes with temperature, humidity, and altitude,

2/n
we wondered if bats have to learn/experience to correctly couple a given delay to a specific distance, and if this is flexible.

So how do we check this? The trick was to change the speed of sound! we trained adults & pups to fly to a target, and enriched the air with helium

Happy New Year's Eve! To end 2020 & prep us for the New Year, I'm excited to talk today about one of my favorite bat topics:

How YOU can help #bats! 🥳🥳🥳🥳🦇🦇🦇🦇

#BatTwitter #BatConservation
[Tweet by @BatsForLife]
Why do we need to help #bats? ~1/3 of bat species worldwide are endangered, vulnerable, or "data deficient" (i.e. more conservation attention is needed for the species). That's a lot of species that need our help!

In North America, one of the most devastating threats to bats is White-nose Syndrome, caused by a fungus in hibernation caves that kills up to 99% of a colony. Only 10% of the once-abundant Little brown bat remains 😰

Cool Bat Fact #1: The Smallest Bat
Let's start with the smallest & biggest bats in the world

The smallest #bat is a Kitti's hog-nosed bat (aka Bumblebee bat) from Thailand, the size of your thumb tip & weighing less than a penny!

Cool Bat Fact #2: The Biggest Bat

The largest bat is a Golden-crowned flying fox from the Philippines. It has a wingspan of up to 6 feet, but weighs only about 2 pounds. Also, it only eats fruit! 🍑🍍🥭🍌

Today I'd like to start by talking about a topic that has received more attention recently: bats & diseases.
[A thread]
[Tweet by @BatsForLife]
Do bats carry more viruses than other animals? A recent study suggests there are many viruses hosted by bats simply b/c there are many species of bats, not because they are more inherently dangerous to humans than other mammals.

#Bats are AMAZINGLY adept at not getting sick from viruses. Unlike us, bats have mechanisms that reduce viral replication & dampen immune response to viruses. The result: their immune systems control viruses but they don't get sick.
