Published New research reveals the impact of different species and their traits on human wellbeing



New research has revealed that well-functioning ecosystems are crucial to human health and wellbeing, with human-biodiversity interactions delivering wellbeing gains equating to substantial healthcare cost-savings, when scaled-up across populations.
Published Supersized fruit eater database on climate change frontline



To conserve precious and fragile biodiversity hotspots, a crucial step is knowing how the fruit eaters are doing. To assist in that, scientists and students have supersized a database to keep track of such animals and birds.
Published Cryo conservation: A cool solution to saving species from extinction



In the face of the biodiversity crisis, and alarming data showing a 69% decline in global animal populations since 1970, researchers are banking on a cool solution to help save species from extinction. Much like egg-freezing is used to preserve human fertility options for a later date, the cryo-freezing of genetic samples taken from animals may play an essential role in curbing species extinctions. A new study sheds light on the immense potential of living cell banks, also known as cryobanks, to contribute to global conservation priorities.
Published These long-necked reptiles were decapitated by their predators, fossil evidence confirms



In the age of dinosaurs, many marine reptiles had extremely long necks compared to reptiles today. While it was clearly a successful evolutionary strategy, paleontologists have long suspected that their long-necked bodies made them vulnerable to predators. Now, after almost 200 years of continued research, direct fossil evidence confirms this scenario for the first time in the most graphic way imaginable.
Published Study shows ancient Alaskans were freshwater fishers



A scientific team has discovered the earliest-known evidence of freshwater fishing by ancient people in the Americas. The research offers a glimpse at how early humans used a changing landscape and could offer insight for modern people facing similar changes.
Published Scientists discover urea in atmosphere revealing profound consequences for climate



Areas of the ocean that are rich in marine life are having a bigger impact on our ecosystems and the climate than previously thought, new research suggests.
Published Researchers find high risk to amphibians if fungal pathogen invades North America



New research indicates the fungal pathogen Batrachochytrium salamandrivorans (Bsal) could be devastating to amphibian biodiversity if introduced to North America.
Published Hotter sand from microplastics could affect sea turtle development



New research has found that extreme concentrations of microplastics could increase the temperature of beach sand enough to threaten the development of incubating sea turtles.
Published Scientists investigate the evolution of animal developmental mechanisms, show how some of Earth's earliest animals evolved



Lacking bones, brains, and even a complete gut, the body plans of simple animals like sea anemones appear to have little in common with humans and their vertebrate kin. Nevertheless, new research shows that appearances can be deceiving, and that a common genetic toolkit can be deployed in different ways to drive embryological development to produce very different adult body plans. It is well established that sea anemones, corals, and their jellyfish relatives shared a common ancestor with humans that plied the Earth's ancient oceans over 600 million years ago. A new study from the Gibson Lab, published in Current Biology on June 13, 2023, illuminates the genetic basis for body plan development in the starlet sea anemone, Nematostella vectensis. This new knowledge paints a vivid picture of how some of the earliest animals on earth progressed from egg to embryo to adult.
Published Why certain fish are left off the hook



A new study found that while a piece of legislation designed to foster the sustainability of marine fisheries is sometimes blamed for being too stringent -- leading to what some politicians call 'underfishing' -- the law is not constraining most fisheries, and there are various other reasons that lead to certain fish species being less fished.
Published Lost giants: New study reveals the abundance decline of African megafauna



A groundbreaking new paper focuses on the size and abundance of living and fossil African large mammals, shedding light on the ecological dynamics behind the decline of these iconic creatures. The findings challenge previous assumptions about the causes of megafaunal extinctions in Africa and provide new insights into the restructuring of ecosystems over millions of years.
Published When water temperatures change, the molecular motors of cephalopods do too



Working with live squid hatchlings, scientists find the animals can tune their proteome on the fly in response to changes in ocean temperature via the unique process of RNA recoding. The findings inspire new questions about basic protein function.
Published Team finds reliable predictor of plant species persistence, coexistence



Ecological scientists have long sought ways to measure and predict how specific plant communities will fare over time. Which species in a diverse population will persist and coexist? Which will decline? What factors might contribute to continuing biodiversity? Researchers report on a new method for determining whether pairs or groups of plant species are likely to coexist over time.
Published Sea cucumbers: The marine delicacy that can deter diabetes



They're a marine delicacy loved across Asia, but the humble sea cucumber is also proving to be a key ingredient in preventing diabetes, according to new research.
Published Coral disease tripled in the last 25 years. Three-quarters will likely be diseased by next century



Research suggests warming temperatures will see nearly 80 per cent of coral in reefs diseased in the next 80 years.
Published Older trees accumulate more mutations than their younger counterparts



A study of the relationship between the growth rate of tropical trees and the frequency of genetic mutations they accumulate suggests that older, long-lived trees play a greater role in generating and maintaining genetic diversity than short-lived trees.
Published Viruses hidden in coral symbiont's genetic material are a potential threat to reefs



Microscopic algae that corals need for survival harbor a common and possibly disease-causing virus in their genetic material.
Published Whales not to be counted on as 'climate savers'



Do whales increase the removal of carbon from the atmosphere? Despite some hope that this would be the case, a new study has found the amount of potential carbon capture by whales is too little to meaningfully alter the course of climate change. The team found the amount potentially sequestered by the whales was too minimal to make significant impact on the trajectory of climate change.
Published Air quality stations have collected vast stores of DNA by accident, a potentially 'game-changing' discovery for tracking global biodiversity



The accelerating loss of biodiversity and increasing rate of species extinction is a major threat to ecosystems around the globe. And yet, quantifying those losses at a large scale hasn't been possible, in large part due to a lack of the required infrastructure. But a new study shows that a major source for such information already exists in the form of environmental DNA (eDNA), which has been inadvertently collected in filters by thousands of ambient air quality monitoring stations in countries around the world for decades.
Published Fungi stores a third of carbon from fossil fuel emissions and could be essential to reaching net zero, new study reveals



Mycorrhizal fungi are responsible for holding up to 36 per cent of yearly global fossil fuel emissions below ground -- more than China emits each year.
