Cumulative stress restricts niche filling potential of habitat-forming kelps in a future climate. [PDF]

open access: yesFunct Ecol, 2018
Plain Language Summary Abstract Climate change is driving range contractions and local population extinctions across the globe. When this affects ecosystem engineers the vacant niches left behind are likely to alter the wider ecosystem unless a similar species can fulfil them.

How Air Temperature and Solar Radiation Impact Life History Traits in a Wild Insect. [PDF]

open access: yesEcol Evol
Ectotherms are essential components of all ecosystems and rely on external heat to regulate their body temperature. We studied the effects of air temperature and shading on crickets reared at different altitudes and found that development time was influenced primarily by temperature, whereas mass at adulthood depended on the interaction between shading

Non‐native species outperform natives in coastal marine ecosystems subjected to warming and freshening events

open access: yesGlobal Ecology and Biogeography, Volume 30, Issue 8, Page 1698-1712, August 2021., 2021
Abstract Aims Contemporary climate change and biological invasions are two main drivers of biodiversity redistribution. Interactive effects between these drivers have been reported in a variety of studies, yet results are conflicting. Some studies find that contemporary climate change facilitates the spread and success of non‐native species, especially

Larval dispersal in a changing ocean with an emphasis on upwelling regions

open access: yesEcosphere, Volume 11, Issue 1, January 2020., 2020
Abstract Dispersal of benthic species in the sea is mediated primarily through small, vulnerable larvae that must survive minutes to months as members of the plankton community while being transported by strong, dynamic currents. As climate change alters ocean conditions, the dispersal of these larvae will be affected, with pervasive ecological and ...

Some don't like it hot: microhabitat-dependent thermal and water stresses in a trailing edge population [PDF]

open access: yes, 2014
The distributional limits of species in response to environmental change are usually studied at large temporal and/or geographical scales. However, organismal scale habitat variation can be overlooked when investigating large-scale averages of key ...
