Turf wars: Ocean acidification and feedback loops lock in turf algal systems
Researchers from the University of Tsukuba have found that seawater acidification locked marine communities of turf algae in a stable state, preventing the growth of kelp and coral species. The degraded turf algal systems were stabilized by feedback loops (control mechanisms in a system). This study will contribute to efforts to manage shifts from complex and diverse marine ecosystems to degraded ones, and better conserve coastal ecosystems and their contributions to human wellbeing. (2021-02-16)

New insights to past ecosystems are now available based on pollen and plant traits
Researchers have mined and combined information from two databases to link pollen and key plant traits to generate confidence in the ability to reconstruct past ecosystem services. The approach can help understand how plants performed different benefits useful for humans over the past 21,000 years, and how these services responded to human and climate disturbances. (2021-02-11)

New study reveals biodiversity important at regional scales
New research shows that biodiversity is important not just at the traditional scale of short-term plot experiments--in which ecologists monitor the health of a single meadow, forest grove, or pond after manipulating its species counts--but when measured over decades and across regional landscapes as well. The findings can help guide conservation planning and enhance efforts to make human communities more sustainable. (2021-02-11)

What's the catch? Algal blooms influence fishing booms
The timing of phytoplankton blooms in the Red Sea could help determine next year's fish catch. (2021-02-10)

Researchers uncover hidden hunting tactics of wolves in Minnesota's Northwoods
In a new paper published in the journal Behavioral Ecology, researchers from the University of Minnesota and the Voyageurs Wolf Project--which studies wolves in the Greater Voyageurs Ecosystem in the northwoods of Minnesota--show that wolves have evolved ambush hunting tactics specifically tailored for catching and killing beavers. The study challenges the classic concept that wolves are solely cursorial predators. Instead, wolf-hunting strategies appear highly flexible, and they are able to switch between hunting modes (cursorial and ambush hunting) depending on their prey. (2021-02-09)

Kangaroo overgrazing could be jeopardising land conservation, study finds
The native species has reached numbers that are contributing to drier soil and less vegetation - and may be more damaging to conservation areas than rabbits. (2021-02-03)

Wellbeing benefits of wetlands
Australians love their beaches, and now a new study also confirms the broad appeal of other coastal assets such as tidal wetlands, nature trails and protected areas including bird and dolphin sanctuaries. In one of the first studies of its kind in Australia, ahead of World Wetlands Day (2 February), Flinders University environment and marine ecology experts have conducted an Adelaide-based survey of how residents connect with and rate the attributes of Adelaide's northern metropolitan coastal wetlands. (2021-01-31)

Accounting for the gaps in ancient food webs
Studying ancient food webs can help scientists reconstruct communities of species, many long extinct, and even use those insights to figure out how modern-day communities might change in the future. There's just one problem: only some species left enough of a trace for scientists to find eons later, leaving large gaps in the fossil record -- and researchers' ability to piece together the food webs from the past. (2021-01-14)

Energy sorghum may combine best of annual, perennial bioenergy crops
Researchers at the Department of Energy's Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) found that energy sorghum, an annual crop, behaves more like the perennial grass miscanthus in the way it efficiently captures light and uses water to produce abundant biomass. The findings highlight energy sorghum's potential as a sustainable bioenergy crop and provide critical data for biogeochemical and ecological models used to forecast crop growth, productivity, and sustainability.

Capturing 40 years of climate change for an endangered Montana prairie
Over 40 years of monitoring, an endangered bunchgrass prairie became hotter, drier and more susceptible to fire annually--but dramatic seasonal changes (not annual climate trends) seem to be driving the biggest changes in plant production, composition, and summer senescence. Gary Belovsky and Jennifer Slade of The University of Notre Dame, Indiana, present these findings in the open-access journal PLOS ONE on December 23, 2020. (2020-12-23)

King of the Cave: New centipede on top of the food chain in the sulphurous-soaked Movile
A new species of endemic, troglobiont centipede was discovered by an international team of scientists in the Romanian cave Movile: a unique underground ecosystem, isolated several millions years ago during the Neogene, whose animal life only exists because of the chemosynthetic bacteria. As the largest Movile's inhabitant, the new species can easily be crowned as the 'king' of this 'hellish' ecosystem. Aptly named Cryptops speleorex, the cave-dweller is described in the open-access, peer-reviewed journal ZooKeys. (2020-12-16)

More frequent and extreme marine heatwaves likely to threaten starfish

Carolina Sandhills Salamander: New species added to species-rich North Carolina
Already possessing more salamander species than any other state in the country with 63, North Carolina has just added one more to make it 64. The aptly named Carolina Sandhills Salamander (Eurycea arenicola) is found in association with springs, seepages and small blackwater streams of the Sandhills region of North Carolina. (2020-12-11)

Low oxygen levels in lakes and reservoirs may accelerate global change
Ultimately, this study is crucial for how researchers, and the general public, think about how freshwater ecosystems produce greenhouse gases in the future. With low oxygen concentrations increasing in lakes and reservoirs across the world, these ecosystems will produce higher concentrations of methane in the future, leading to more global warming. (2020-12-10)

Index reveals integrity issues for many of the world's forests
Only 40 per cent of forests are considered to have high ecological integrity, according to a new global measure, the Forest Landscape Integrity Index. The Index was created by 47 forest and conservation experts from across the world, including Professor James Watson of The University of Queensland and the Wildlife Conservation Society. (2020-12-09)

Nature conservation requires more dynamic approach to weather impacts of climate change
A new hard-hitting paper, titled ''Post-2020 biodiversity targets need to embrace climate change'' argues that nature conservation strategies need to become more flexible and dynamic in how it addresses the impact of climate change on natural habitats, genetic resources of plants, the composition of species, and the functioning of ecosystems. If not, any apparent short-term gains in reversing biodiversity loss could be lost in the decades to follow, due to climate change. (2020-12-09)

Nature s contributions to people found to be in decline
Over the past 50 years, declining biodiversity has put many of nature s contributions to people at risk. This is the conclusion reached by fifteen leading international experts, including a French ethnoecologist at the CNRS. Based on the IPBES Global Assessment, their work is the subject of an article, published this week in the journal PNAS, which discusses the risks to human well-being and prosperity resulting from the continuing degradation of the environment. (2020-12-09)

Late-season Arctic research cruise reveals warm ocean temperatures, active ecosystem
Arctic researchers have been visiting the Bering and Chukchi seas off Alaska for nearly 30 years, collecting information about the biological diversity of the watery world under the sea ice. This year, a late-season research cruise revealed a surprise. At a time of year when an ice-breaking ship is usually required to get to some of the data-gathering outposts, scientists found nothing but open water and an unusually active ecosystem. (2020-11-11)
