by Staatliche Naturwissenschaftliche Sammlungen Bayerns January 11, 2023 Ein unglaublicher Fischfang im Bodensee gab Expert:innen seit 2014 eine ganze Fülle von Rätseln auf. Wissenschaftler:innen der Fischereiforschungsstelle Langenargen (FFS/LAZBW) sowie des Wasserforschungsinstituts der Schweiz (EAWAG) entdeckten damals einige Exemplare des Tiefseesaiblings in ihren Netzen – nachdem dieser über 40 Jahre lang verschollen war. Hatte man den bis zu 25 cm langen…

New research has identified North America’s climate change refugia, habitats that will be the most likely to support the persistence of the greatest amount of biodiversity in the face of a changing climate.

Research supported by the Northeast CASC, and recently published in Ecological Applications, has shed light on the knowledge gaps that need to be addressed to effectively manage invasive species.

When an outbreak of sylvatic plague decimated black-tailed prairie dog numbers in the Thunder Basin National Grassland in 2017, researchers saw an opportunity for a “natural experiment” to explore the impact of the rodents’ die-off on the plants and other wildlife in that area of northeast Wyoming.

by CNRS December 24, 2022 Un humain vit actuellement à une distance moyenne de 9,7 km d’une zone naturelle, soit 7 % plus loin qu’en 2000 d’après une étude publiée dans Frontiers in Ecology and the Environment. C’est en Europe et dans l’Est de l’Asie que cette distance est la plus élevée avec par exemple 22 km en Allemagne et…

Wageningen researchers have discovered how turtles change their grazing behaviour when they feel safe, and as a result increase their grazing pressure on seagrass meadows.

Comparing the genetics and relocation patterns of habitat “haves” and “have-nots” among two populations of threatened rattlesnakes has produced a new way to use scientific landscape data to guide conservation planning that would give the “have-nots” a better chance of surviving.

In a paper recently published in the journal Ecosphere, McCullough and a team of researchers evaluated the current capacity of freshwater networks in the lower 48 states to act as natural highways for freshwater wildlife.

A multidisciplinary historical ecology research carried out in Pollino National Park reveals that rewilding processes have contributed to the conservation and local expansion of the relic mixed beech-fir forest during the last thousand years.

A team from the Martin Luther University Halle-Wittenberg and the Hamburg Authorities for the Environment, Climate, Energy and Agriculture has now shown how research can benefit from this historic habitat mapping data using habitat maps of the city and federal state of Hamburg as an example.

New research published in the journal Ecology conclusively shows that certain physical traits of flowers affect the health of bumble bees by modulating the transmission of a harmful pathogen called Crithidia bombi.

Prescribed fire could play a role in reducing the abundance of ticks and the transmission of disease pathogens they carry, according to a team of scientists.

A community science case study mapped heavy metals in moss in two industrial-adjacent neighborhoods in Seattle, Washington, yielding findings that have prompted short-term mitigation and followup instrumental air quality monitoring.

Ecologists measured plant-soil feedbacks for six perennial prairie grass species in a short-term greenhouse study, and say their findings do not match outcomes observed in other long-term experiments.

The best time to deal with diseases in marine species is before an outbreak occurs, a study by Oregon State University shows.

New research by Oregon State University sheds light on the ability of steelhead, cutthroat and rainbow trout to endure the higher water temperatures expected to accompany climate change and its manifestations, including increased frequency, extent and severity of wildfires.

by Consiglio Nazionale delle Ricerche September 29, 2022 Per oltre 150 anni, le specie ittiche indo-pacifiche hanno colonizzato il Mediterraneo entrando dal Canale di Suez. Una ricerca coordinata dal Cnr-Irbim indica la possibilità che il fenomeno si estenda verso l’Oceano Atlantico a causa dei cambiamenti climatici. Il lavoro è stato recentemente pubblicato su Frontiers in Ecology and the Environment. Una…

A new study by a research team from Arizona State University has found that climate change will dramatically increase the intensity of locust swarms, resulting in even more crops lost to insect pests and threatening food security.

by Università degli Studi di Milano Statale September 27, 2022 A causa del cambiamento climatico, la migrazione primaverile degli uccelli verso i siti di nidificazione e la loro riproduzione sono anticipate di circa 2-3 giorni ogni decennio, a partire dal 1811. E le specie che tendono ad anticipare maggiormente le loro attività sono quelle residenti e i migratori parziali, quelle…

A new study shows that as the Arctic warms faster than any other part of the world, polar bears can’t feast on blubber from multiple seals as they’re used to doing. Instead, they’re finding fewer seals and eating more muscle, increasing their consumption of protein relative to fat.
