Marine Fish Parasites: A Bibliometric Review
This bibliometric study analyzes 11,368 publications on marine fish parasites from Web of Science and Scopus. The results reveal leading countries, institutions, and journals, and identify three main research clusters: parasitology, genetics, and marine ecology. Recent thematic evolution highlights a growing focus on aquaculture applications, including

Whence Lotka-Volterra? Conservation Laws and Integrable Systems in Ecology [PDF]
Abstract Competition in ecology is often modeled in terms of direct, negative effects of one individual on another. An example is logistic growth, modeling the effects of intraspecific competition, while the Lotka-Volterra equations for competition extend this to systems of multiple species, with varying strengths of intra- and inter ...

A general framework for invasion cycles in ecology
Abstract Theory predicts that indirect interactions in ecological networks sustain species diversity through oscillatory dynamics. However, a framework linking interaction structure to the presence, type, and complexity of these cycles is lacking. Here, we develop an analytical toolbox combining invasion graphs with a mathematical decomposition of ...
