Scale-dependent effects of host patch traits on species composition in a stickleback parasite metacommunity. [PDF]

Ecology, 2020
Abstract A core goal of ecology is to understand the abiotic and biotic variables that regulate species distributions and community composition. A major obstacle is that the rules governing species distributions can change with spatial scale. Here, we illustrate this point using data from a spatially nested metacommunity of parasites infecting a ...

Fish morphological and parasitological traits as ecological indicators of habitat quality in a Mediterranean coastal lagoon

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 33, Issue 11, Page 1229-1244, November 2023., 2023
Abstract Coastal lagoons are key ‘transitional’ aquatic environments for biodiversity conservation. Ecological indicators are useful tools for the management of water resources in the European Union. Among different biological communities, fish are a very sensitive tool to assess environmental integrity.
