Published Saturated soils could impact survival of young trees planted to address climate change (via sciencedaily.com) Original source
New research has looked into the potential effects of increased rainfall in regions being earmarked for expansion of temperate rainforests. Amid global calls for more trees to be planted as part of efforts to combat climate change, this study highlights the importance of factoring in soil conditions when looking at where and how to create the temperate rainforests of the future.
Published Limited adaptability makes freshwater bacteria vulnerable to climate change (via sciencedaily.com) Original source
Freshwater bacteria with small genomes frequently undergo prolonged periods of adaptive stagnation. Based on genomic analyses of samples from European lakes, researchers uncovered specific evolutionary strategies that shape these bacteria's lifestyles. Understanding the evolutionary dynamics of aquatic microbial communities is key to safeguarding ecosystem services.
Published Stony coral tissue loss disease is shifting the ecological balance of Caribbean reefs (via sciencedaily.com) Original source
A new study shows stony coral tissue loss disease is causing drastic changes in the Caribbean's population of corals, which is sure to disrupt the delicate balance of the ecosystem and threaten marine biodiversity and coastal economies.
Published Climate change could become the main driver of biodiversity decline by mid-century (via sciencedaily.com) Original source
Global biodiversity has declined between 2% and 11% during the 20th century due to land-use change alone, according to a large multi-model study. Projections show climate change could become the main driver of biodiversity decline by the mid-21st century.
Published Deer are expanding north, and that's not good for caribou (via sciencedaily.com) Original source
In the boreal forest of Western Canada, researchers have considered that both changing climate and increased habitat alteration have enabled deer to push farther north.
Published Unveiling the lionfish invasion in the Mediterranean Sea (via sciencedaily.com) Original source
Researchers have published a comprehensive study on the invasion of lionfish in the Mediterranean Sea, highlighting a rapid spread and the potential ecological impacts. The research shows the lionfish species Pterois miles has significantly expanded its territory in the Mediterranean since the invasion began around ten years ago. The invasive species has established presence in the eastern Mediterranean, with observations now extending to colder waters previously thought to be unsuitable for the species.
Published Diversity and productivity go branch-in-branch (via sciencedaily.com) Original source
Researchers found that forests with higher trait diversity not only adapt better to climate change but may also thrive. The study unveiled how tree functional trait diversity plays a pivotal role in mitigating climate warming. In the face of environmental stress, these diverse trees have been shown to maintain higher productivity levels, in contrast to monoculture forests.
Published Invasive species sound off about impending ecosystem changes (via sciencedaily.com) Original source
Anticipating changes to ecosystems is often at best an educated guess, but what if there was a way to better tune into possible changes occurring? Researchers have discovered that the silent growth of non-native invasive plants can affect the soundscape of an ecosystem. These altered soundscapes, the acoustic patterns of a landscape through space and time, may provide a key to better observing the hard-to-see physical and biological changes occurring in an ecosystem as they are beginning.
Published Lemur's lament: When one vulnerable species stalks another (via sciencedaily.com) Original source
What can be done when one threatened animal kills another? Scientists studying critically endangered lemurs in Madagascar confronted this difficult reality when they witnessed attacks on lemurs by another vulnerable species, a carnivore called a fosa.
Published Marine microbial populations: Potential sensors of the global change in the ocean (via sciencedaily.com) Original source
Animal and plant populations have been extensively studied, which has helped to understand ecosystem processes and evolutionary adaptations. However, this has not been the case with microbial populations due to the impossibility of isolating, culturing and analyzing the genetic content of the different species and their individuals in the laboratory. Therefore, although it is known that populations of microorganisms include a great diversity, this remains largely uncharacterized.
Published Unique field study shows how climate change affects fire-impacted forests (via sciencedaily.com) Original source
During the unusually dry year of 2018, Sweden was hit by numerous forest fires. A research team has investigated how climate change affects recently burnt boreal forests and their ability to absorb carbon dioxide.
Published Coral reef microbes point to new way to assess ecosystem health (via sciencedaily.com) Original source
A new study shows that ocean acidification is changing the mix of microbes in coral reef systems, which can be used to assess ecosystem health.
Published Tropical forests can't recover naturally without fruit-eating birds (via sciencedaily.com) Original source
Natural forest regeneration is hailed as a cost-effective way to restore biodiversity and sequester carbon. However, the fragmentation of tropical forests has restricted the movement of large birds limiting their capacity to disperse seeds and restore healthy forests.
Published Where have all the right whales gone? (via sciencedaily.com) Original source
Marine researchers have mapped the density of one of the most endangered large whale species worldwide, the North Atlantic right whale, using new data to help avoid right whales' harmful exposure to commercial fisheries and vessel strikes. The resulting maps, spanning 20 years of whale observations, are publicly available to inform risk assessments, estimations of whale harm/disturbance, marine spatial planning, and industry regulations to mitigate risk to right whales.
Published Geobiology: New placozoan habitat discovered (via sciencedaily.com) Original source
Traces of DNA in the stomachs of predatory snails give a team og geobiologists new insights into the ecology of placozoans.
Published Ants in Colorado are on the move due to climate change (via sciencedaily.com) Original source
Ant species living in Boulder's foothills have shifted their habitat over the last six decades, potentially affecting local ecosystems, suggests a new study.
Published Deforestation harms biodiversity of the Amazon's perfume-loving orchid bees (via sciencedaily.com) Original source
A survey of orchid bees in the Brazilian Amazon, carried out in the 1990s, is shedding new light the impact of deforestation on the scent-collecting pollinators, which some view as bellwethers of biodiversity in the neotropics.
Published 'Teacher Toads' can save native animals from toxic cane toads (via sciencedaily.com) Original source
Scientists from Macquarie University have come up with an innovative way to stop cane toads killing native wildlife by training goannas to avoid eating the deadly amphibians.
Published Impact of climate change on marine life much bigger than previously known (via sciencedaily.com) Original source
Fish and invertebrate animals are far more affected by warmer and more acidic seawater than was previously known. The big gain of the new method is that more details become known about effects of climate change on species.
Published Humans can increase biodiversity, archaeological study shows (via sciencedaily.com) Original source
Through the ages, the presence of humans has increased the heterogeneity and complexity of ecosystems and has often had a positive effect on their biodiversity.
