Archives of Polish Fisheries, 2014 The subject of the study was four populations of signal crayfish from Naryjska Struga River and lakes Pobłędzie, Mauda, and Staw Płociczno. The morphometric differentiation of female and male signal crayfish was studied with discriminant analysis. It was

Flooding affects fluctuating asymmetry but not growth of a riparian orbweaving spider
Ecological Entomology, Volume 51, Issue 3, Page 547-557, June 2026.In a mesocosm experiment we assessed the impact of flood on aquatic insect emergence and on spider development using geometric morphometric analysis of fluctuating asymmetry. We observed 45% higher emergence in flooded mesocosm throughout the season. Spiders did not grow bigger but exhibited ~15% lower fluctuating asymmetry than in controls.

Cost of parasite exposure depends on host ontogeny 寄生接觸的代價依賴於宿主發育階段
Ecological Entomology, Volume 51, Issue 3, Page 592-603, June 2026.The cost of parasite exposure varies across host developmental stages, demonstrating that ontogeny influences the expression of non‐consumptive effects (NCEs). Mite exposure resulted in consumptive effects in fly eggs and NCEs in early‐stage pupae; mite longevity was comparable when provisioned with pupae or water but increased when provisioned with ...

Signal crayfish are susceptible to crayfish plague infection under physiological challenge
, 2013 The carrier status and possible elevated resistance against the crayfish plaque (Aphanomyces astaci) of signal crayfish has been speculated for several decades. We studied the responses of two signal crayfish (Pacifastacus leniusculus) populations against the virulent crayfish plague infections under laboratory conditions.

Size‐Dependent Habitat Selection in a Tropical Freshwater Crayfish: Preference for Vegetated Refugia
Ecology and Evolution, Volume 16, Issue 5, May 2026.Young freshwater crayfish need shelter to survive, but it is often unclear whether they actively choose safe habitats or simply remain where they are found. We show that craylings and juvenile red claw crayfish prefer vegetated habitats over bare sand or gravel, and that this preference becomes stronger as crayfish grow.
