Light pollution and invasive species: how spiders’ diets change

Night-time lighting and invasive species are changing food webs in ways we rarely notice. In this blog post, Collins explores how artificial light at night and invasive signal crayfish reshape spider diets and alter aquatic-terrestrial resource pathways.

How algae and fungi team up to nourish aquatic invertebrates

Figure for how algae and fungi team up to nourish aquatic invertebrates

In this blog post, Alexander Feckler and his colleagues explore the role of autochthonous primary production for the quality of microbially-colonized leaf material as food in heterotrophic food web in headwater streams. Despite reduced autochthonous primary production in shaded headwater streams, this study indicated a potential for enhanced secondary production and energy transfer to higher trophic levels within the aquatic ecosystem due to so-called “algal priming”.
