An ecological rule breaker shows the effects of climate change on body size evolution

A study by McGill University researchers found that Northern Tree Shrews' body size increased with warmer climates, contradicting Bergmann's rule. The team analyzed museum specimens and historical climate data, revealing a reversal of the Island rule as well, highlighting the complex interaction between ecological factors.

Bat diversity and abundance are highest in old deciduous forest stands on the river banks in Eastern Ukraine

A new study reveals that bat diversity is highest in old deciduous forest stands on river banks in Eastern Ukraine. The research found that mature forests older than 90 years improve breeding activity and abundance of bats, with species richness increasing up to 22% of all forests in the region.

Wildlife disease ecologist launches project to help DoD monitor quality of bird habitats on military installations

A new study aims to assess habitat quality by analyzing arthropod food resources in bird diets and vegetation, providing an effective and cost-efficient way for DoD land managers to monitor threatened species. The project uses advanced genetic approaches and bioinformatics expertise to measure habitat quality on military installations.

Rhino conservation in Nepal creates a burden for communities, infrastructure and other species, study warns

A new study by Michelle Szydlowski from the University of Exeter warns that rhino conservation efforts in Nepal are putting a burden on communities, infrastructure, and other species. The study found that successful anti-poaching campaigns have increased tourist numbers and rhino populations, but also led to human and animal casualties.

Guiding conservation with local touch

A group of biologists is exploring the potential of seed banks, frozen zoos, gene editing, and assisted gene flow to create second chances for species affected by climate change. By understanding local adaptation strategies, conservationists can design more effective conservation actions.

Calcifying organisms, under threat from a combination of ocean warming and acidification

A new study reveals that global warming and ocean acidification are threatening marine organisms with calcium carbonate skeletons, such as corals and sea urchins. The researchers found a clear pattern showing that species with high levels of magnesium in their skeletons become more common with warmer seawater temperatures.

Egyptian lagoon vital to Cyprus turtles

A study by the University of Exeter found that 74% of green turtles foraging in Cyprus feed at Lake Bardawil, an Egyptian lagoon. The number of turtle nests has increased almost tripled since the early 1990s, but their dependence on this single location leaves them vulnerable to changes in conditions.

Study reveals how ancient fish colonized the deep sea

Scientists discovered that ancient fish favored cold, dark waters of the deep sea, challenging the assumption that shallow habitats have always been diverse. The study revealed three major events that drove speciation rates in the deep sea, including the breakup of Pangea and the Cretaceous Hot Greenhouse period.

Bees active in woodland tree-tops, research shows

New research from the University of East Anglia reveals that wild bees are actively foraging in the sunlit woodland canopy, particularly among Sycamore trees. A diverse community of wild bees was found to thrive in this habitat, with nectar and pollen-rich trees providing essential food sources.

Diverse landscapes at the heart of bee conservation

Researchers found that small amounts of development can positively impact bee species in a given area, revealing the importance of forest remnants and blended landscapes. The study discovered 111 species, representing 20% of known Georgia bee species, and provided a framework for future research to assist in bee conservation.

Warming oceans are changing Australian reef fish populations

Researchers analyzed data from Australia's Reef Life Survey and two major reef monitoring programs to understand the effects of warming waters on reef fish populations. The study found that temperature changes had a greater impact on temperate reefs, while tropical reefs were more affected by habitat changes such as coral bleaching.

HKU initiates Global Ant Census

A recent study by the University of Hong Kong estimates that there are between 20 x 10^15 and 2 x 10^17 individuals on Earth, weighing more than all wild birds and mammals combined. The study also found that ants are unevenly distributed over the global land surface, with tropical regions harbouring more ants than non-tropical regions.

North American birds not fully adjusting to changing climate

At least 30 out of 114 North American bird species have become less well-adjusted to their climate over the last 30 years, according to a recent study. Climate decoupling, where species distributions and abundances diverge from climate conditions, is particularly prominent among habitat specialists.
