DOI: 10.1002/ecy.2600
Abstract: Sodium (Na) has a unique role in food webs as a nutrient primarily limiting for plant consumers, but not other trophic levels. Environmental Na levels vary with proximity to coasts, local geomorphology, climate, and with… read more here.

DOI: 10.1002/ecy.3587
Abstract: Impacts of environmental stressors on food webs are often difficult to predict because trophic levels can respond in divergent ways, and biotic interactions may dampen or amplify responses. Here we studied food-web level impacts of… read more here.

DOI: 10.1002/ecy.3949
Abstract: Food web ecology has revolutionized our understanding of ecological processes, but the drivers of food web properties like trophic position (TP) and food chain length are notoriously enigmatic. In terrestrial ecosystems, above- and belowground systems… read more here.

DOI: 10.1002/lno.11474
Abstract: Chytrid fungal parasites are ubiquitous in aquatic ecosystems and infect a wide array of aquatic organisms, including all phytoplankton groups. In addition to their role as parasites, chytrids serve as food to zooplankton, thereby establishing… read more here.

The commonality of core biological groups across freshwater food webs
Sign Up to like & getrecommendations! Published in 2021 at "Limnology and Oceanography"
DOI: 10.1002/lno.11697
Abstract: Assessing how organisms interact is fundamental to understand biodiversity patterns. Like many ecosystems, most freshwater environments are susceptible to spatial and temporal variations, especially floodplains. In spite of the expected variability, the structure of interactions… read more here.
