Critical slowing down suggests that the western Greenland Ice Sheet is close to a tipping point
Publication ID: pub.1138112198
Publication date: 17/05/2021
Keywords: Critical Slowing Down; Early-warning Signals; Greenland Ice Sheet (GrIS); Tipping Points
The Greenland Ice Sheet (GrIS) is a potentially unstable component of the Earth system and may exhibit a critical transition under ongoing global warming. Mass reductions of the GrIS have substantial impacts on global sea level and the speed of the Atlantic Meridional Overturning Circulation, due to the additional freshwater caused by increased meltwater runoff […]
Plastic contamination of a Galapagos Island (Ecuador) and the relative risks to native marine species
Publication ID: pub.1137970038
Publication date: 13/05/2021
Keywords: Ecosystem; Ecuador; Environmental Monitoring; Galapagos Islands; Plastics; Risk; San Cristobal Island; Water Pollutants, Chemical
Ecuador’s Galapagos Islands and their unique biodiversity are a global conservation priority. We explored the presence, composition and environmental drivers of plastic contamination across the marine ecosystem at an island scale, investigated uptake in marine invertebrates and designed a systematic priority scoring analysis to identify the most vulnerable vertebrate species. Beach contamination varied by site […]
Global declines in coral reef calcium carbonate production under ocean acidification and warming
Publication ID: pub.1137889577
Publication date: 10/05/2021
Keywords: Calcification; Carbonate Production; Climate Change; Corals; Global
Ocean warming and acidification threaten the future growth of coral reefs. This is because the calcifying coral reef taxa that construct the calcium carbonate frameworks and cement the reef together are highly sensitive to ocean warming and acidification. However, the global-scale effects of ocean warming and acidification on rates of coral reef net carbonate production […]
Prolonged Siberian heat of 2020 almost impossible without human influence
Publication ID: pub.1137812623
Publication date: 06/05/2021
Keywords: Extreme Event Attribution; Extremes; Heatwave; Multi-model; Rapid Attribution; Siberia; Verkhoyansk
Over the first half of 2020, Siberia experienced the warmest period from January to June since records began and on the 20th of June the weather station at Verkhoyansk reported 38 °C, the highest daily maximum temperature recorded north of the Arctic Circle. We present a multi-model, multi-method analysis on how anthropogenic climate change affected the […]
Carbon loss from forest degradation exceeds that from deforestation in the Brazilian Amazon
Publication ID: pub.1137602502
Publication date: 29/04/2021
Keywords: Aboveground Biomass (AGB); Amazon; Biodiversity; Brazil; Carbon Losses; Climate; Deforestation; Degradation; Forest Area; Forest Protection; Policy Priorities; Spatial-temporal Dynamics
Spatial–temporal dynamics of aboveground biomass (AGB) and forest area affect the carbon cycle, climate and biodiversity in the Brazilian Amazon. Here we investigate interannual changes in AGB and forest area by analysing satellite-based annual AGB and forest area datasets. We found that the gross forest area loss was larger in 2019 than in 2015, possibly […]
The Functional Significance of Bacterial Predators
Publication ID: pub.1137507036
Publication date: 27/04/2021
Keywords: Bdellovibrio; Cytophaga; Food Webs; Lysobacter; North America; Predator; qSIP; Stable Isotope Probing; Top-down Control; Trophic Interactions; Vampirovibrionales; 18O-H2O
Predation structures food webs, influences energy flow, and alters rates and pathways of nutrient cycling through ecosystems, effects that are well documented for macroscopic predators. In the microbial world, predatory bacteria are common, yet little is known about their rates of growth and roles in energy flows through microbial food webs, in part because these […]
