Land-sea relationship is major driver of coral reef health outcomes      (via sciencedaily.com)     Original source 

New research indicates that mitigating both local land and sea-based human impacts, especially in terms of pollutants and over-fishing, provides coral reef ecosystems with the best opportunity to persist under climate change. Along some highly populated areas on the shorelines of Hawai'i, wastewater pollution and urban runoff combine with fishing pressures to put immense stress on coral reefs.

Pause in recent coral recovery on much of Great Barrier Reef      (via sciencedaily.com) 

In-water monitoring shows hard coral cover across the Great Barrier Reef remains at similar levels to that recorded in 2022, with small decreases in the Northern, Central and Southern regions. AIMS' Annual Summary Report on Coral Reef Condition for 2022/23 found that while some reefs continued to recover, their increased hard coral cover was offset by coral loss on other reefs. Most reefs underwent little change in coral cover.

Researchers are using monkey poop to learn how an endangered species chooses its mates      (via sciencedaily.com)     Original source 

Northern muriquis, which live in the Atlantic forest of Brazil, are one of the most endangered species of monkey in the world. To better understand what goes on in the mating lives of muriquis, researchers turned to the monkeys' poop to help gain insight into how the primates choose their mates.

Why you shouldn't declaw tigers or other big cats      (via sciencedaily.com)     Original source 

Researchers looked at the effects of declawing on larger cat species and found that declawing disproportionately impacts their muscular capabilities as compared to their smaller brethren.

New research highlights risks of selective adaptation in extreme coral habitats      (via sciencedaily.com)     Original source 

Resilient corals, often referred to as 'super corals', have recently been seen as potential saviours in the face of climate change and its detrimental effects on coral reefs. Now, a team of scientists is working to better understand these corals in order to develop strategies to protect fragile ecosystems such as the Great Barrier Reef.

Scientists vacuum animal DNA from air in a Danish forest      (via sciencedaily.com)     Original source 

Over 60 animal species in three days. That is how many mammals, birds and amphibians researchers found DNA traces from in the air in a Danish forest. The results can pave the way for a new and innovative way of mapping biodiversity.

Fast electrical signals mapped in plants with new bioelectronic technology      (via sciencedaily.com)     Original source 

What happens inside the carnivorous plant Venus Flytrap when it catches an insect? New technology has led to discoveries about the electrical signalling that causes the trap to snap shut. Bioelectronic technology enables advanced research into how plants react to their surroundings, and to stress.

Genetic study reveals that a captive-bred population could save endangered crocodile from extinction      (via sciencedaily.com)     Original source 

Performing a genetic evaluation on the largest captive-bred population of the critically endangered Orinoco crocodile, researchers have revealed that the population preserves much of its founder diversity and no inbreeding, making it suitable for implementing wild releases. Since this species is almost extinct in the wild, the news brings hope for the recovery of populations.

Soil microbes help plants cope with drought, but not how scientists thought      (via sciencedaily.com)     Original source 

In a multi-generation experiment, researchers found microbes helped plants cope with drought, but not in response to plants' cries for help. Instead, the environment itself selected for drought-tolerant microbes. And while those hardy microbes were doing their thing, they just happened to make plants more drought-tolerant, too.
