Published Heat waves harm bird reproduction on agricultural lands
(via sciencedaily.com) Original source The effects of extreme temperatures on avian reproduction can vary depending on the type of environment that birds call home. A new study found that extreme high temperatures significantly diminish bird reproductive success in agricultural landscapes.
Published Holy bat skull! Fossil adds vital piece to bat evolution puzzle
(via sciencedaily.com) Original source Bats may have lived in caves and used soundwaves to navigate much earlier than first thought.
Published Pinpointing the emergence of muddy flavors in your fish
(via sciencedaily.com) Original source Many people have experienced a muddy off-flavor in farmed fish. While the aquaculture industry has known about the problem for 20 years, it continues to impact the consumption of otherwise healthy and potentially sustainable fish. Now, researchers have been able to pinpoint exactly when the off-flavors emerge. And this can make it easier to deal with the compounds that turn people away from farmed fish.
Published Biodegradable plastics still damaging to fish
(via sciencedaily.com) Original source Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a new study showing they are still harmful to fish.
Published Reef-devouring predator survives coral bleaching and feasts on the survivors
(via sciencedaily.com) Original source The crown-of-thorns starfish is nature's ultimate coral predator that has a circle of life perfectly adapted to warming waters.
Published Critical step made for managing brushtail possums
(via sciencedaily.com) Original source Researchers say mapping the genetic code of the brushtail possum will benefit those working to both conserve and control the animal.
Published AI models identify biodiversity from animal sounds in tropical rainforests
(via sciencedaily.com) Original source Animal sounds are a very good indicator of biodiversity in tropical reforestation areas. Researchers demonstrate this by using sound recordings and AI models.
Published Genomic analysis in snakes shows link between neutral, functional genetic diversity
(via sciencedaily.com) Original source In the world of threatened and endangered species conservation, the genomic revolution has raised some complicated questions: How can scientists justify assessing species genetic diversity without consulting entire genomes now that they can be sequenced? But then again, how can scientists justify the time and expense of genome sequencing when age-old measures of neutral genetic diversity are much cheaper and easier to obtain? A new study suggests making a transition from 'old school' genetics to 'new school' genomics for species conservation purposes probably isn't necessary in all cases.
Published New threat to Antarctic fur seals
(via sciencedaily.com) Original source Populations of charismatic animals have recovered since hunting ban but now struggle to find enough food.
Published Flagship individual animals can boost conservation
(via sciencedaily.com) Original source 'Flagship' individual animals like Cecil the lion or Freya the walrus can boost conservation, new research suggests.
Published Tens of thousands of endangered sharks and rays caught off Congo
(via sciencedaily.com) Original source Tens of thousands of endangered sharks and rays are caught by small-scale fisheries off the Republic of the Congo each year, new research shows.
Published Killer whales' diet more important than location for pollutant exposure
(via sciencedaily.com) Original source Both elegant and fierce, killer whales are some of the oceans' top predators, but even they can be exposed to environmental pollution. Now, in the largest study to date on North Atlantic killer whales, researchers report the levels of legacy and emerging pollutants in 162 individuals' blubber. The animals' diet, rather than location, greatly impacted contaminant levels and potential health risks -- information that's helpful to conservation efforts.
Published Death is only the beginning: Birds disperse eaten insects' eggs
(via sciencedaily.com) Original source Relationship patterns among flightless stick insects suggest that birds disperse the eggs after eating gravid females. Lab experiments previously suggested the possibility, but a new genetic analysis of natural populations in Japan now supports the idea.
Published Wild pig populations in U.S. can be managed
(via sciencedaily.com) Original source Recent conservation efforts have proven effective at controlling wild pig populations in the Southeastern United States, according to new research. Within 24 months of the start of control efforts in the study area located around the Savannah River Site in Aiken, South Carolina, researchers found a reduction of about 70% in relative abundance of pigs and a corresponding decline in environmental rooting damage of about 99%.
Published The changing climate creates more noise in the oceans
(via sciencedaily.com) Original source Due to the changing climate, the underwater world is getting ever noisier.
Published Researchers identify largest ever solar storm in ancient 14,300-year-old tree rings
(via sciencedaily.com) Original source An international team of scientists have discovered a huge spike in radiocarbon levels 14,300 years ago by analyzing ancient tree-rings found in the French Alps. The radiocarbon spike was caused by a massive solar storm, the biggest ever identified. A similar solar storm today would be catastrophic for modern technological society – potentially wiping out telecommunications and satellite systems, causing massive electricity grid blackouts, and costing us billions. The academics are warning of the importance of understanding such storms to protect our global communications and energy infrastructure for the future.
Published Long-term lizard study challenges the rules of evolutionary biology
(via sciencedaily.com) Original source Researchers measured natural selection in four Anolis lizard species in the wild for five consecutive time periods over three years. This long-term study in a community of lizards reveals how evolution unfolds in the wild across multiple species.
Published Natural GM crops: Grasses take evolutionary shortcut by borrowing genes from their neighbors
(via sciencedaily.com) Original source Grass may transfer genes from their neighbors in the same way genetically modified crops are made, a new study has revealed.
Published Fear of humans pervades the South African savanna
(via sciencedaily.com) Original source Mammals living in South Africa's Greater Kruger National Park, home to one of the world's largest remaining lion populations, are far more afraid of hearing human voices than lion vocalizations or hunting sounds such as dogs barking or gunshots.
Published Survival of the newest: the mammals that survive mass extinctions aren't as 'boring' as scientists thought
(via sciencedaily.com) Original source For decades, scientists have assumed that mammals and their relatives that survived challenging times (like those during mass extinctions) made it because they were generalists that were able to eat just about anything and adapt to whatever life threw at them. A new study into the mammal family tree through multiple mass extinctions revealed that the species that survived aren't as generic as scientists had thought: instead, having new and different traits can be the key to succeeding in the aftermath of a catastrophe.
