Trophic structure of a pond community dominated by an invasive alien species: Insights from stomach content and stable isotope analyses

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 31, Issue 4, Page 948-963, April 2021., 2021
Abstract Invaders affect native species across multiple trophic levels, influencing the structure and stability of freshwater communities. Based on the ‘trophic position hypothesis’, invaders at the top of the food web are more harmful to native species via direct and indirect effects than trophically analogous native predators are. However, introduced

Phylogenetic analysis of the Camaenidae (Mollusca: Stylommatophora) with special emphasis on the american taxa [PDF]

open access: yes, 2003
