Published New study shows surprising effects of fire in North America's boreal forests



Using satellite images, researchers found that fires in North America's boreal forest may be changing the environment in ways that researchers didn't previously anticipate.
Published Soil carried on sea freight loaded with dangerous pests and diseases, research finds



While sea freight is recognised as a pathway for the movement of exotic organisms, there is little research that has quantified the risk. Soil collected from the external surfaces of sea freight was found to support live microorganisms, worms, seeds and insects, including various regulated biosecurity organisms. The research confirms that shipping containers provide a pathway for the movement of exotic species.
Published Scientists discover deepest known evidence of coral reef bleaching



Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.
Published Waves of change: How sea-levels and climate altered the marine ecosystems at the South Pole 390-385 million years ago



New research reveals a chain of environmental disasters. These took place in what is today's South Africa, during an ancient time period called the Early-Middle Devonian. The crises led to the extinction of a unique group of marine animals called the Malvinoxhosan biota.
Published Reef-devouring predator survives coral bleaching and feasts on the survivors



The crown-of-thorns starfish is nature's ultimate coral predator that has a circle of life perfectly adapted to warming waters.
Published Whaling wiped out far more fin whales than previously thought



Whaling in the 20th century destroyed 99% of the Eastern North Pacific fin whale breeding population. Because there is enough genetic diversity, current conservation measures should help the population rebound without becoming inbred. The future of fin whales in the Gulf of California depends on the recovery of the Eastern North Pacific population.
Published Subalpine forests in the Northern Rockies are fire resilient--for now



Using lake sediment cores, scientists determined how these subalpine ecosystems recovered after 4,800 years of fire.
Published Surprising discovery about coral's resilience could help reefs survive climate change



A team has studied the mountainous star coral, Orbicella faveolata, to determine whether coral populations that have survived higher temperatures can pass their heat tolerance on to their offspring. To the scientists' surprise, the results showed the opposite: The offspring from a population that is less heat-tolerant performed better when exposed to high temperatures than their counterparts from a heat-tolerant population. The findings counter the commonly held notion among scientists that if coral parents can handle the heat, so should their offspring.
Published How to help save plants from extinction



Now is the time to identify the conditions that cause plants to die. Doing so will allow us to better protect plants by choosing conservation targets more strategically, botanists argue.
Published AI models identify biodiversity from animal sounds in tropical rainforests



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



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



Populations of charismatic animals have recovered since hunting ban but now struggle to find enough food.
Published Wildfires threaten environmental gains in climate-crucial Amazon



Despite steps toward decreasing deforestation, uncontrolled wildfires are threatening environmental gains in Brazilian Amazonia, one of the world's most critical carbon sinks and a region of high biological and cultural diversity.
Published Research shows wildfire smoke may linger in homes long after initial blaze



Newly published research on indoor air quality shows wildfire smoke may linger in homes long after the initial blaze has been put out or winds have shifted. The findings show that wildfire smoke can attach to home surfaces like carpet, drapes or counters -- extending the exposure for those inside and potentially causing health problems even after an initial cleaning activity by air purifiers.
Published Gray whales experience major population swings as a result of Arctic conditions



Dynamic and changing Arctic Ocean conditions have likely caused three major mortality events in the eastern North Pacific gray whale population since the 1980s.
Published Coffee and cocoa plants at risk from pollinator loss



Tropical crops such as coffee, cocoa, watermelon and mango may be at risk due to the loss of insect pollinators, finds a new study.
Published Extraordinary fossil find reveals details about the weight and diet of extinct saber-toothed marsupial



A 13-million-year-old saber-toothed marsupial skeleton discovered during paleontological explorations in Colombia is the most complete specimen recovered in the region.
Published Bouldering in south-central Madagascar: A new 'rock-climbing' gecko species of the genus Paroedura



A new Paroedura gecko species was reported at two small forest sites, Anja Reserve and Tsaranoro Valley forest, in the south-central plateau of Madagascar. Thanks to the recently collected samples, it was described and named after its preferred habitat, the boulders surrounded by the last remaining forests at these sites. Its conservation status was evaluated as Critically Endangered given its tiny distributional range.
Published Tens of thousands of endangered sharks and rays caught off Congo



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 Epiphytes, amazing plants like moss and bromeliads found in trees, face growing threats



Epiphytes, plants such as orchids and mosses that grow in trees, draw nutrients from the air and create refuge for all sorts of other life forms. They are the foundation of forest canopy ecosystems, but they are facing threats from human and natural disturbances.
