Abstract:
Given a branching random walk on a set $X$, we study its extinction probability vectors $mathbf{q}(cdot,A)$. Their components are the probability that the process goes extinct in a fixed $Asubseteq X$, when starting from a vertex $xin X$. The set of extinction probability vectors (obtained letting $A$ vary among all subsets of $X$) is a subset of the set of the fixed points of the generating function of the branching random walk. In particular here we are interested in the cardinality of the set of extinction probability vectors. We prove results which allow to understand whether the probability of extinction in a set $A$ is different from the one of extinction in another set $B$. In many cases there are only two possible extinction probability vectors and so far, in more complicated examples, only a finite number of distinct extinction probability vectors had been explicitly found. Whether a branching random walk could have an infinite number of distinct extinction probability vectors was not known. We apply our results to construct examples of branching random walks with uncountably many distinct extinction probability vectors.

Arizona is expected to repeal its longstanding ban on bilingual education, following similar moves in California and Massachusetts in recent years.

The late Devonian mass extinction around 375 million years ago may not have really happened, according to an analysis using machine learning

Many people assume an asteroid triggered the mass extinction that killed the dinosaurs, but geologists say massive volcanic eruptions occurred at the same time

The Permian extinction, which wiped out almost all complex life, may have been caused by the undersides of continents slipping off into Earth’s interior

The fossil record tells us extinctions happen all the time. The question is what part we play – and whether we could ever bring back creatures like the dinosaurs

We investigated whether cycloheximide (CHX) would induce amnesia for the stress-induced impairment of extinction retrieval. First, a single restraint stress session was demonstrated to impair extinction retrieval, but not fear conditioning. A second experiment showed that when CHX was administered immediately after restraint, rats exhibited significant extinction retrieval at test (i.e., retrograde amnesia for the stress). In a third experiment, the stress session impaired various amounts of extinction durations, suggesting that the stress inhibited extinction retrieval rather than enhancing the original fear learning. These results suggest memories for acute stress are susceptible to disruption, which could have clinical implications.

Developer Systemic Reaction has announced three-player, online cooperative shooter, Second Extinction, for the Xbox Series X, Xbox One and Windows PC via Steam.

"I’m very proud of what our team has created," said Systemic Reaction managing director Tobias Andersson. "As a live game, we plan to support Second Extinction long-term, as we do with all our titles. We can’t wait for players to team up, start playing, and become part of our community."

Lead producer Brynley Gibson added, "Second Extinction is a real passion project for our tight-knit team, and we’re just getting started. It’s incredible how far we’ve come in this short time, and I’m super excited to reveal more details, including our live roadmap, in the coming months."

View the announcement trailer below:

Here is an overview of the game:

Second Extinction is an intense three-player cooperative shooter, where your goal is to wipe out the mutated dinosaurs that have taken over the planet. Teamwork is  vital as you adopt the role of one of the survivors, using a unique combination of  weapons, abilities and skills to take on the vast number of enemies. Fight through  a maelstrom of bullets, bombs, teeth, claws and gore, it’s up to you to reclaim  Earth!

Key Features:

• Intense Three-Player Co-Op – Earth is overrun by mutated dinosaurs! Team up with up to two other resistance fighters to take it back in short but intense combat operations.
• Battle Mutated Monstrosities – These dinos are nothing like the ones in your history books! From electric raptors  to behemoth T-Rexes that tower over the horizon, these deadly creatures have evolved into the ultimate killing machines.
• Experience Spectacular Action – Combine your fireteam’s unique weapons and abilities for explosive results  against overwhelming opposition in challenging combat set pieces.
• Take Part in a Joint Effort – Your actions, together with the rest of the community, will shape the course of  the war against the dinosaurs.

The highly distinctive and mostly endemic Australian land mammal fauna has suffered an extraordinary rate of extinction (>10% of the 273 endemic terrestrial species) over the last ∼200 y: in comparison, only one native land mammal from continental North America became extinct since European settlement.

The coral is composed of many small polyps and forms large colonies approximately 2 metres across. The polyp skeleton is a dusky pink colour.

As of December 2017, fewer than 50 individuals are thought to be remaining in three subpopulations that are scattered over 140,000 square km in Iran’s central plateau. The cats have been nearly wiped out by excessive hunting, habitat degradation and scarcity of prey species.

These wild mushrooms usually fetch between 50 and 70 Euros per kilogram. This encourages people to collect and sell the mushrooms, often before they are mature. It is estimated that only 250 White Ferulas make it to maturity each year.

Since the 1940s, this species has attracted considerable attention because of its plasticity; in the 1950s, tests were carried out to introduce the species into various open stretches of water (Baltic Sea) or closed areas (lakes). The farming of this species

Georgia aster is currently found in five US counties in Alabama, 15 in Georgia, nine in North Carolina and 14 in South Carolina. It was once known from Florida, but is no longer found there. Across its range, 146 total populations have been known, of these, 28 have likely disappeared.

Unlike other members of this family, the eyes of the Ganges shark are tilted dorsally, instead of laterally or ventrally, indicating that it may swim along the river bed scanning the waters above for prey. Its sharp and slender teeth suggest that it is primarily a fi sh-eater. It is often confused with the bull shark, which is known to attack humans

The plant has been listed as a threatened species in the United States since 1989, and in 2008 it was listed as an endangered species by the IUCN.

Between 2012 and 2018, the Black Rhino (Diceros bicornis) population across Africa has grown at a modest annual rate of 2.5% from an estimated 4,845 to 5,630 animals in the wild, respectively. Population models predict a further slow increase over the next five years, according to IUCN’s March 2020 update.

Illegal hunting, habitat loss and changes through expanding agriculture and mining, increasing humanwildlife conflict, and civil unrest are all pushing the species towards extinction.

In 1945, the tree, also known as ‘Kaikomako Manawa Tawhi’, was visited by professor Geoff Baylis, who brought a cutting back to Auckland and nurtured it to maturity at the Department of Scientific and Industrial Research (DSIR).

This incredibly metallic blue tarantula is found within a 39-square mile reserve forest in Andhra Pradesh. Its behaviour parallels that of many arboreal spiders. In the wild, it lives in holes of tall trees where it makes asymmetric funnel webs. Spiders of this genus may live communally when territory, i.e. the number of holes per tree, is limited.

The species is known as the “rice bird” in China, where it is hunted for food — a practice that has been illegal since 1997, but continues on the black market to this day. This practice on migratory passerines in Asia has pushed not only the Yellow-breasted Bunting to the edge of extinction; but led to all migratory bunting species in eastern Asia declining.

The Aye-aye is endangered and on the IUCN red list due to hunting and habitat destruction caused largely by humans setting fi res, illegal logging, making charcoal, as well as agriculture and livestock expansion.
