Mongooses inherit behavior from role models rather than parents
Young mongooses learn lifelong habits from role models rather than inheriting them from genetic parents, new research shows. (2018-05-24)

Imminent extinction of northern white rhinoceros motivates genetic recovery efforts
Earlier this year, the last remaining male northern white rhinoceros (NWR) died in captivity, nearly cementing the fate of this subspecies for extinction. In the wild, continuing threats of poaching, habitat destruction, and small population size have contributed to the rhinos' status as critically endangered. Yet, novel conservation efforts that make use of cryopreserved genetic material could save the NWR, and other threatened species, from extinction. (2018-05-24)

Imminent extinction of northern white rhinoceros motivates new genetic recovery efforts
In a study published today in the journal Genome Research, researchers investigated the genetic history of nine northern white rhino (NWR) cryopreserved cell lines compared to that of a closely related subspecies, the southern white rhino (SWR). Importantly, genetic analyses of variation and inbreeding facilitated identification of cell lines, which may serve as valuable pools of genetic material for genetic rescue. (2018-05-24)

Orphaned elephants change where they live, in response to poaching and the need for food
Young elephants who have lost either their mothers or the matriarchs of the herd are affected dramatically, and change where they live, according to new research. (2018-05-23)

Determining effective methods of irrigation as water becomes increasingly scarce
US consumers prefer the idea of using fresh water for any watering needs. In most cases, plants irrigated with recycled water saw no negative impact when compared to the same types of plants irrigated with pure, non-recycled water. (2018-05-23)

First record of large-antlered muntjac in Vietnam
In November 2017 -- under a biodiversity monitoring and assessment activity supported by the US Agency for International Development -- scientists and conservationists of the Leibniz Institute for Zoo and Wildlife Research and WWF-Vietnam captured photographs of one of the rarest and most threatened mammal species of Southeast Asia, the large-antlered muntjac, in Quang Nam province, central Vietnam.

IUPUI study finds missing link between blow flies and possible pathogen transmission
Determining whether blow flies have consumed animal fecal material versus animal tissue has important implications for both human public health and animal conservation. A recent study by researchers in biology and chemistry at the School of Science at IUPUI shows how that determination can be made. (2018-05-22)

Giant Chinese salamander is at least five distinct species, all heading toward extinction
With individuals weighing in at more than 140 pounds, the critically endangered Chinese giant salamander is well known as the world's largest amphibian. But researchers reporting in Current Biology now find that those giant salamanders aren't one species, but five, and possibly as many as eight. The bad news is that all of the salamanders now face the imminent threat of extinction in the wild, due to demand for the amphibians as luxury food. (2018-05-21)

Giraffes surprise biologists yet again
New research from the University of Bristol has highlighted how little we know about giraffe behaviour and ecology. (2018-05-18)

World's protected areas being rapidly destroyed by humanity
One-third of the world's protected land is under intense human pressure, according to an international study described as 'a stunning reality check' on efforts to avert a biodiversity crisis. The University of Queensland-led research has found six million square kilometers of protected land -- equivalent to two-thirds the size of China -- is in a state unlikely to conserve endangered biodiversity. (2018-05-17)

Climate change in Quebec equals a much greater diversity of species???
A team of researchers believe that, paradoxically, climate change may result in Quebec's national and provincial parks becoming biodiversity refuges of continental importance as the variety of species present there increases. They calculated potential changes in the presence of 529 species in about one third of the protected areas in southern Quebec. Their results suggest that fifty -- eighty years from now (between 2071-2100) close to half of the protected regions of southern Quebec may see a species turnover of greater than 80 %. (2018-05-16)

Traditional knowledge sheds light on changing East Greenland climate and polar bear hunt
Inuit polar bear hunters in East Greenland report changes to their subsistence hunting patterns as well as polar bear distribution and behavior due to decreasing sea ice and the introduction of hunting quotas in 2006. The study is the first in nearly 20 years to document traditional knowledge in East Greenland -- providing a valuable baseline for monitoring future changes and the polar bear population. (2018-05-15)

New research says location of protected areas vital to wildlife survival
A new study, by 17 conservation scientists and environmental scholars, say the exact location of protective wild spaces is just as vital as committing to set these areas aside. (2018-05-14)

OSU researchers question conservation community's acceptance of trophy hunting

What is a species? British bird expert develops a math formula to solve the problem
Whether co-habiting populations belong to the same species is only as tough as figuring out if they interbreed or produce fertile offspring. On the other hand, when populations are geographically separated, biologists often struggle to determine whether they represent different species or merely subspecies. To address the age-long issue, a British bird expert has developed a new universal mathematical formula for determining what is a species. His study is published in the open-access journal ZooKeys.

Alligators on the beach? Killer whales in rivers? Get used to it
Sightings of alligators and other large predators in places where conventional wisdom says they 'shouldn't be' have increased in recent years, in large part because local populations, once hunted to near-extinction, are rebounding. A new Duke-led paper finds that far from being outliers, these sightings signify the return of highly adaptable predators to prime hunting grounds they occupied long ago -- a trend that opens new opportunities for future conservation. (2018-05-07)

If El Niños happen twice as often in the future, what happens to seabirds?
Doubling the frequency of El Niños unexpectedly resulted in higher population numbers and a lower chance of extinction for Brandt's cormorants, a recent UC Davis study found. Does that mean climate change could actually be good for seabirds? Not so fast.   (2018-05-07)

Scientists hark back to Pleistocene to trace prioritary areas for conservation
By recreating a 20,000 years-old South American biome map and then comparing it with current conditions, a Brazilian study identifies intact forest remnants which has greater genetic diversity for they presented high climatic stability in the period. (2018-05-04)

What gorilla poop tells us about evolution and human health

The true 'value' of biodiversity
Planning conservation policies to protect biodiversity using single core 'values' such as the 'usefulness' of a species could put 'less useful' species at risk. (2018-05-03)

Rethinking the umbrella species concept
According to the 'umbrella species' concept, preserving and managing habitat for a single high-profile species also benefits a whole suite of other species that share its habitat -- but how well does this really work? Not all species that share the same general habitat necessarily have the same specific needs, and a new study from The Condor: Ornithological Applications finds that habitat management to benefit greater-sage grouse in Wyoming can actually harm some of its songbird neighbors. (2018-05-02)

Rare sharks are no longer in the 'dark,' thanks to new species survey method
Previously unobserved shark species swim in areas impacted by humans, reports a new study. The results reveal a greater prevalence of sharks in such regions than traditional survey methods have uncovered, and the approach for uncovering them may lead to more thorough species diversity assessments in areas with rare and threatened large animals - often hard to (2018-05-02)

Survival and restoration of China's native forests imperiled by proliferating tree plantations
China's reforestation efforts have led to an increase in tree cover by 32 percent but the increase mostly comes from people turning former croplands into tree plantations with only one type of tree, which is of little value to wildlife. Likewise, native forests actually decreased by 6 percent because people continued to clear native forests to make way for tree plantations. (2018-05-02)

Researchers study how to improve southern sea otter survival
Analysis of 13 years of demographic and genetic data from 1,006 sea otters to assess multiple effective population size estimators, as well as temporal trends in genetic diversity and population genetic structure, show a need for development of new delisting criteria for the southern sea otter. (2018-05-01)

Reefs that experience frequent temperature changes most likely to resist coral bleaching
Reefs subjected to high sea temperature fluctuations on daily or tidal timescales leading up to ocean warming event are better able to resist coral bleaching, such that a 1 degree C increase in daily temperature range reduces the odds of more severe bleaching by a factor of 33. (2018-04-26)

Endangered petrels and trawl fishing clash in Tasman sea
Today's shifting environmental conditions are creating an uncertain future for many top predators in marine ecosystems, but to protect the key habitat of a species, you first have to know where that habitat is and what threats might be affecting it. A new study from The Condor: Ornithological Applications looks at where New Zealand's endangered Westland Petrel forages during its breeding season and shows that its range overlaps more with trawl fishing activity than conservationists realized. (2018-04-25)

Land use and pollution shift female-to-male ratios in snapping turtles
Current research shows that increasing global temperatures as a result of climate change are expected to produce more female turtles since their offspring are influenced by the nest's temperature. But now, a team of Virginia Tech biologists has found that the nesting environment of turtles in agricultural habitats, which can ultimately lower nesting temperatures, can actually produce more males. (2018-04-24)
