Biological invasions: a global assessment of geographic distributions, long‐term trends, and data gaps

open access: yesBiological Reviews, EarlyView.
ABSTRACT Biological invasions are one of the major drivers of biodiversity decline and have been shown to have far‐reaching consequences for society and the economy. Preventing the introduction and spread of alien species represents the most effective solution to reducing their impacts on nature and human well‐being.

Environmental DNA as a tool for hydropower impact assessments: current status, special considerations, and future integration

open access: yesBiological Reviews, EarlyView.
ABSTRACT Globally there is an urgent need to find sustainable solutions to balance energy production with the protection of vulnerable species and conservation of biodiversity. This is particularly critical for freshwater ecosystems, habitats, and species that may be impacted by hydropower development and operations needed to meet energy grid demands ...

Photic-zone euxinia had a major role in the Devonian-Carboniferous boundary mass extinction

open access: yesCommunications Earth & Environment
Marine anoxia is widely proposed as a kill mechanism for the Devonian-Carboniferous boundary mass extinction commonly linked to the end-Devonian Hangenberg Crisis (~359.3 Ma), but the exact connections between primary drivers, marine redox conditions ...

Evaluation of the pollution pressures posed by groups of chemicals on British riverine invertebrate populations

open access: yesBiological Reviews, EarlyView.
ABSTRACT Globally, rivers receive a diverse range of chemicals, including metals, pesticides, persistent organic pollutants, petrochemicals, human and veterinary pharmaceuticals and personal care products. However, the extent to which these different chemical groups affect riverine invertebrate communities is not well defined.

Insights into the forests of Darién, Panama, from the new 10 ha Bacurú Drõa plot established through participatory methods within an Emberá territory

open access: yesConservation Science and Practice, EarlyView.
We present the first data from a new forest plot co‐developed with the Traditional Emberá Authorities of the Balsa River Collective Lands, Darién, Panama: The Bacurú Drõa plot. We compare floristic characteristics and conservation status of trees in BD with those of 53 forest plots across Panama.

Borealization of the Arctic Ocean in Response to Anomalous Advection From Sub-Arctic Seas

open access: yesFrontiers in Marine Science, 2020
An important yet still not well documented aspect of recent changes in the Arctic Ocean is associated with the advection of anomalous sub-Arctic Atlantic- and Pacific-origin waters and biota into the polar basins, a process which we refer to as ...

Variable species establishment in response to microhabitat indicates different likelihoods of climate‐driven range shifts

open access: yesEcography, EarlyView.
Climate change is causing geographic range shifts globally, and understanding the factors that influence species' range expansions is crucial for predicting future biodiversity changes. A common, yet untested, assumption in forecasting approaches is that species will shift beyond current range edges into new habitats as they become macroclimatically ...
