Double jeopardy for ecologically rare birds and terrestrial mammals

Common assumptions notwithstanding, rare species can play unique and essential ecological roles. After studying two databases that together cover all known terrestrial mammals and birds worldwide, scientists from the CNRS, the Foundation for Biodiversity Research (FRB), Université Grenoble Alpes, and the University of Montpellier have demonstrated that, though these species are found on all continents, they are more threatened by human pressures than ecologically common species and will also be more impacted by future climate change. Thus, they are in double jeopardy. The researchers’ findings, published in Nature Communications (October 8, 2020), show that conservation programs must account for the ecological rarity of species.


It has long been thought that rare species contribute little to the functioning of ecosystems. Yet recent studies have discredited that idea: Rarity is a matter not only of the abundance or geographical range of a species, but also of the distinctiveness of its ecological functions. Because these functionally distinct species are irreplaceable, it is essential we understand their ecological characteristics, map their distributions, and evaluate how vulnerable they are to current and future threats.

Using two databases that collect information on the world’s terrestrial mammals (4,654 species) and birds (9,287 species), scientists from the FRB’s Center de Synthèse et d’Analyse de la Biodiversité (CESAB), CNRS research laboratories, Université Grenoble Alpes, the University of Montpellier, and partner institutes divided the earth’s surface into 50 × 50 km squares and determined the number of ecologically rare species within each. They showed that ecological rarity among mammals is concentrated in the tropics and the southern hemisphere, with peaks on Indonesian islands, in Madagascar, and in Costa Rica. Species concerned are mostly nocturnal frugivores, like bats and lemurs, and insectivores, such as small rodents. Ecologically rare bird species are mainly found in tropical and subtropical

Common assumptions notwithstanding, rare species can play unique and essential ecological roles. After studying two databases that together cover all known terrestrial mammals and birds worldwide, scientists from the CNRS, the Foundation for Biodiversity Research (FRB), Université Grenoble Alpes, and the University of Montpellier[1] have demonstrated that, though these species are found on all continents, they are more threatened by human pressures than ecologically common species and will also be more impacted by future climate change.

How To Speed Up Home Internet

  • Anyone wondering how to speed up your home internet without dropping a ton of cash on an overpriced mesh Wi-Fi system will be happy to hear that it’s much easier and less expensive than you think.
  • If you’re sick of slow internet speeds and “buffering” on your computer, TV, or video game console, there’s a simple device that will be a game-changer for you.
  • Before you do something drastic like buying a new router or a pricey mesh Wi-Fi system, check out the TP-Link AV1000 Gigabit Powerline Internet Kit, which is just $49.99 on Amazon.

When you’re trying to watch a video or stream a game, slow internet speeds and buffering can be your worst nightmare. It’s so aggravating, but it happens all the time. What you might not realize though, is that there’s a wonderfully easy way for most people to fix this problem.

A lot of the time, it’s your Wi-Fi connection that is the main source of the issue. Sometimes there’s interference, or if you live in a big household it could be a congestion problem. It could also be an issue with range, and you can get away with a cheap fix by picking up a Wi-Fi range extender. The best-selling TP-Link model on Amazon is on sale right now for just $19.99, or you can go all-out with TP-Link’s fastest extender ever for $89.99.

But if you want the best possible fix with the fastest and most reliable connection, you need to ditch wireless on your device and switch to a wired internet connection. Of course, no one wants to spend hundreds of dollars installing Ethernet, and we would never suggest that. Why bother when you can instantly transform any regular old power outlet

When And Where You Can See Mars Shine With A ‘Harvest Moon’ While Venus Appears As ‘Double Star’

0 Comments

On Friday, October 2—just a day after Thursday’s full “Harvest Moon” rises at dusk—our satellite will appear to pass very close to a very bright planet Mars.

It’s going to be a special sight, and a reasonably rare one, too, because Mars is about to reach its brightest since 2003.

Do you know where and in the night sky to watch the moonrise and a Mars-rise? Or when to catch it?

Here’s exactly what you need to know to see this special celestial sight just after dusk on Friday—and the bonus sight of Venus shining super-close to bright star Regulus.

When to see Mars and the Moon close together

When: Moonrise on Friday, October 2, 2020

Where: due east

After full Moon for the northern hemisphere on October 1, 2020—when our satellite will rise close to dusk—the following evening it will rise slightly later in a darker sky. As it does it will appear with Mars at its side. All you need to do it find out the time of moonrise where you are and the time of the Mars-rise where you are, which will be virtually the same time.

Here are a few examples for Friday, October 2, 2020:

  • London: Moonrise is at 19:14 p.m. BST, Mars-rise is also at 19:14 p.m. BST
  • New York: Moonrise is at 19:20 p.m. EDT, Mars-rise is at 19:19 p.m. EDT
  • Los Angeles: Moonrise is at 19:24 p.m. PDT, Mars-rise is at 19:20 p.m. PDT

Inhaler is the medical device that is used to cure respiratory diseases. Smart inhalers have inbuilt digital sensors that helps in recording the usage of an inhaler at the time of access and provides easier access to the user as it can be connected via Bluetooth to their mobile phone. It also gives the information regarding previous dose taken and gives suggestion accordingly. Smart Inhalers can generate alerts for the daily dosage for the user. Advantage over conventional inhalers technological advancements, improving adherence to inhalers, linking with tele-health, and due to extensive use of smart computing devices, the demand for smart inhalers is growing rapidly. Data security concern related to security devices, regulating government policies for the use of healthcare devices, and also limited availability of these products in potential emerging regions will hamper the growth of the market.
