Complementary Non‐invasive Fish Monitoring Distinguishes Depth‐Dependent Fish Communities

open access: yesEnvironmental DNA
Human activities are increasingly affecting marine environments, with fish communities serving as critical indicators of ecosystem health. Effective management of marine fishes is imperative for maintaining the balance of marine ecosystems, necessitating

The consequences of balanced harvesting of fish communities [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2014
Balanced harvesting, where species or individuals are exploited in accordance with their productivity, has been proposed as a way to minimize the effects of fishing on marine fish communities and ecosystems. This calls for a thorough examination of the consequences balanced harvesting has on fish community structure and yield.

Ecology of sound communication in fishes [PDF]

open access: yesFish and Fisheries, 2019
AbstractFishes communicate acoustically under ecological constraints which may modify or hinder signal transmission and detection and may also be risky. This makes it important to know if and to what degree fishes can modify acoustic signalling when key ecological factors—predation pressure, noise and ambient temperature—vary.

Does Stream Size Really Explain Biodiversity Patterns in Lotic Systems? A Call for Mechanistic Explanations

open access: yesDiversity, 2017
Understanding drivers of biodiversity is a long-standing goal of basic and applied ecological research. In riverine systems, there remains a critical need to identify these drivers as efforts to manage and protect rivers grow increasingly desperate in ...
