Additional crayfish survey of Checkley Brook, Hollywood End Brook and Black Brook (Goyt) 1999 [PDF]

open access: yes, 1999
This is the report on the Additonal Crayfish Survey of Checkley Brook, Hollywood End Brook and Black Brook from 1999 by the Environment agency. The aim of the 1999 survey was to obtain a more complete picture of the crayfish distribution in those areas.

Aquatic macroinvertebrate responses to native and non-native predators [PDF]

open access: yes, 2014
Non-native species can profoundly affect native ecosystems through trophic interactions with native species. Native prey may respond differently to non-native versus native predators since they lack prior experience.

Phylogenetically‐Informed Crayfish Conservation in the Face of Climate Change

open access: yesAnimal Conservation, EarlyView.
Crayfish are a vital part of freshwater ecosystems, yet one third of assessed species are threatened with extinction, and almost 90% are highly sensitive to climate change. In this study, we produced a phylogenetically‐informed species prioritisation for crayfish conservation and explored the impacts of projected climate change scenarios on crayfish ...

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

Two indigenous European crayfish under threat – how can we retain them in aquatic ecosystems for the future?

open access: yesKnowledge and Management of Aquatic Ecosystems, 2011
Indigenous crayfish species (ICS) are under threat in Europe; due to competition from invasive non-indigenous crayfish species (NICS) from crayfish plague, which is carried by introduced American crayfish, and habitat degradation.

The Effects of Intraspecific Variation of Crayfish Behavior on Nutrient Cycling in Aquatic Environments [PDF]

open access: yes, 2020
Human activities are rapidly altering species traits at a global scale. Yet, there remains a critical need to determine whether trait variation within species affects ecosystem responses to global change. In particular, intraspecific variation in feeding

Movement patterns and shelter choice of spiny-cheek crayfish (Orconectes limosus) in a large lake’s littoral zone [PDF]

open access: yes, 2016
he study of individual movement patterns and habitat choice is a fundamental step to assess an invasive species’ range extension and to inform possible management options.

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Inventory of the Decapod Crustaceans (Crayfishes and Shrimps) of Arkansas with a Discussion of Their Habitats [PDF]

open access: yes, 1980
The freshwater decapod crustaceans of Arkansas presently consist of two species of shrimps and 51 taxa of crayfishes divided into 47 species and four subspecies. The shrimps are represented by Macrobranchium ohione and Palaemonetes kadiakensis.
