Phylogenetic Diversity of the Red Swamp Crayfish Procambarus clarkii and Its Dispersal Pattern in Northern and Central Italy

open access: yesBiology, 2023
The red swamp crayfish Procambarus clarkii is one of the most threatening freshwater species in the world. The aim of this study is to provide a better understanding of the phylogeography and the invasion routes of P.

Transcriptomic analysis of Procambarus clarkii affected by “Black May” disease [PDF]

open access: yesScientific Reports, 2020
AbstractEach year from April to May, high mortality rates are reported in red swamp crayfish (Procambarus clarkii) cultured in Jiangsu and other regions, in China, and this phenomenon has come to be known as “Black May” disease (BMD). Therefore, in order to investigate the possible causes of this disease, this study gathered BMD-affected P.

The Co-ordination of Swimmeret Movements in the Crayfish, Procambarus Clarkii (Girard) [PDF]

open access: yes, 1960
1. Electrical activity recorded in the first roots of the abdominal nerve cord show bursts of activity which accompany rhythmic movements of the swimmerets. These bursts persist when a root is cut distal to the electrodes. 2.

Invasion biology in non-free-living species: interactions between abiotic (climatic) and biotic (host availability) factors in geographical space in crayfish commensals (Ostracoda, Entocytheridae) [PDF]

open access: yes, 2013
In invasion processes, both abiotic and biotic factors are considered essential, but the latter are usually disregarded when modeling the potential spread of exotic species.

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

Ecological design of a crayfishing program to control population density of the invasive species Procambarus Clarkii in Doñana National Park freshwater marsh (Spain) [PDF]

open access: yes, 2016
The exploitation of Procambarus clarkii in Doñana National Park’s freshwater marsh (DNP) has been economically important to the local human population since the 1970s.

Dimensions of dace dynamics: temporal variation in abundance and survival of an imperiled desert fish guide habitat restoration

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Desert fishes are vulnerable to anthropogenic environmental alterations that degrade habitat and reduce water availability, but these same fishes benefit from restoration actions that reverse the causes of decline. Ash Meadows speckled dace (Rhinichthys osculus nevadensis) is a federally endangered minnow endemic to the Mojave ...

Tissue distributions and seasonal dynamics of the hepatotoxic microcystins-LR and -RR in two freshwater shrimps, Palaemon modestus and Macrobrachium nipponensis, from a large shallow, eutrophic lake of the subtropical China [PDF]

open access: yes, 2005
So far no information is available on microcystin (MC) contents in shrimps, prawns or crayfish from natural freshwaters. Tissue distributions and seasonal dynamics of the hepatotoxic MC-LR and -RR in two freshwater shrimps, Palaemon modestus and ...

On the evidence for evidence‐based conservation

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
We explore the evidence base underlying evidence‐based conservation (EBC). Drawing on varied examples, we suggest that EBC is often (but not always) a justified investment to improve conservation outcomes. We offer suggestions for how to generate further evidence on EBC, framed around a theory of change for how EBC improves conservation outcomes ...
