Ecotoxicology and Environmental Safety, 2022 In this study, we exposed adult male crayfish (Procambarus clarkii) to different concentrations of diclofenac (DCF) for 96 h. In the meantime, we investigated the alternations of hepatopancreatic pathology, molecular regulation and intestinal microbiota ...

Naphthalene-Induced Atresia in the Ovary of the Crayfish, Procambarus clarkii
Ecotoxicology and Environmental Safety, 1995 Female crayfish, Procambarus clarkii, were exposed to 10 ppm naphthalene to determine its effect on ovarian development. Ovaries were removed for examination after 1, 2, 4, 6, 8, 10, 12, and 15 days of exposure to the naphthalene. Crayfish that had been exposed to naphthalene for 15 days were then returned to clean freshwater for 1, 2, 4, 5, 7, 10, and

Histological organization of the intestine in the crayfish Procambarus clarkii
Acta Zoologica, 2004 AbstractSix longitudinal ridges span the length of the intestine in the crayfish Procambarus clarkii. A simple columnar epithelium with tetralaminar cuticle lines the lumen. Folds of the epithelium overlie a dense irregular connective tissue packed with mixed acinar (alveolar) glands.

On the evidence for evidence‐based conservation
Ecological 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 ...

Ecology and Evolution, Volume 16, Issue 4, April 2026.ABSTRACT The amphibian disease chytridiomycosis, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), has devastated global amphibian biodiversity. The specific reasons for its rapid global spread, especially to pristine areas, are not well understood. Freshwater invertebrates might function as carriers of Bd, but the diversity and extent
