Chemical changes in the adductor muscle of the cheliped of the crayfish in relation to the double motor innervation [PDF]
, 1938 Work from this laboratory has shown that a number of the striated muscles of the legs of the crayfish show a typical motor innervation (1). Such muscles are innervated by two motor fibers only, each causing a different type of contraction.

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 ...

Does the Density of Invasive Rusty Crayfish Affect Stream Macroinvertebrates? [PDF]
, 2009 Rusty crayfish (_Orconectes rusticus_) have invaded streams of the upper Susquehanna River catchment (New York, USA), replacing native crayfish and probably increasing overall crayfish density.

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.

HABITAT PREFERENCE OF DIFFERENT SIZE CLASSES OF AUSTROPOTAMOBIUS PALLIPES IN AN IRISH RIVER
Knowledge and Management of Aquatic Ecosystems, 2003 Juvenile and immature crayfish are more difficult to find than adults and in consequence rather little is known about their habitat preferences. Smaller crayfish are able to inhabit different areas within the stream compared to adult crayfish.

Ecography, Volume 2026, Issue 5, May 2026.The rapid adoption of environmental DNA (eDNA) methods has drastically changed biodiversity monitoring efforts. It is often claimed that eDNA methods are more sensitive and efficient than conventional biodiversity monitoring methods, but it is often unclear what metrics support this claim.

Ecosphere, Volume 17, Issue 5, May 2026.Abstract Soil extracellular enzymes are produced and excreted by soil microbial organisms. They catalyze many of the biochemical reactions that support crucial ecosystem functions like decomposition, organic matter mineralization, nutrient cycling, and C sequestration.
