Newly discovered diversity within European branchiobdellids – a story of co-evolution and a need for conservation

Knowledge and Management of Aquatic Ecosystems
Branchiobdellids are small ectosymbiotic annelids living primarily on freshwater crayfish. Because humans frequently translocate crayfish, these symbionts can be co-translocated, with implications for biosecurity and conservation.

Disease‐associated mortality drives reduction in Yukon River Chinook salmon escapement: A novel method for quantifying the negative impacts of ‘misfit’ parasites to improve fisheries management

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Alaska Department of Fish and Game is implementing an annual monitoring program at the mouth of the Yukon River where our model will estimate the proportion of Chinook salmon at risk from parasite‐induced mortality to inform annual management. Moreover, the model is broadly applicable to other fungal‐like and myxozoan parasites of conservation concern,

Growth and population dynamics of crayfish Paranephrops planifrons in streams within native forest and pastoral land uses

, 2002
Population dynamics of crayfish (Paranephrops planifrons White) in streams draining native forest and pastoral catchments, Waikato, New Zealand, were investigated from September 1996 to July 1998.

Signal Crayfish in Lake Saimaa Could be Maladapted to the Local Conditions Due to Aphanomyces astaci Infection: A Seven-Year Study [Elektronisk resurs]

, 2016
We conducted a seven-year survey (years 2009 to 2015) of the Lake Saimaa signal crayfish population. Lake Saimaa is the largest single waterbody in Finland, with a productive fishery and crayfishery.

SPECIES OF BRANCHIOBDELLIDAE (ANNELIDA) ON FRESHWATER CRAYFISH IN SOUTH TYROL (NORTHERN ITALY)

Knowledge and Management of Aquatic Ecosystems, 2002
Twenty-eight freshwater crayfish were collected from 8 streams and one small lake in the province of South Tyrol (North Italy) from autumn 1999 to spring 2001, in order to investigate the presence of branchiobdellidans.

Phylogenetically‐Informed Crayfish Conservation in the Face of Climate Change

Animal Conservation, Volume 29, Issue 3, Page 274-284, June 2026.
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 ...

Consequences for lotic ecosystems of invasion by signal crayfish

, 2012
PhDNon-native invasive species are major drivers of biodiversity loss and ecosystemlevel modification. The signal crayfish (Pacifastacus leniusculus) is a highly successful invasive species and demonstrates traits often seen in keystone species ...

UNDERSTANDING AND MANAGING BIODIVERSITY IN RELATION TO NATIVE CRAYFISH POPULATIONS IN EUROPE

Knowledge and Management of Aquatic Ecosystems, 2003
The loss or diminution of European crayfish populations because of both habitat deterioration and competition with alien crayfish – also responsible for the dissemination of the crayfish plague – would reduce the biodiversity at the species level.

Multiple global‐change drivers and cascading effects in Mediterranean ecosystems: Lessons from an iconic national park

Conservation Science and Practice, Volume 8, Issue 6, June 2026.
Mediterranean ecosystems face complex, multi‐trophic impacts from global‐change drivers, yet responses are often studied in isolation. Using the Doñana Protected Area as a case study, we illustrate how anthropogenic pressures on key species like cork oaks and rabbits, as well as increases in species like wild boar and invasive crayfish, lead to ...
