Specific testicular morphology in the atherinomorphOdontesthes nigricans(Richardson, 1848): a comparison with the sympatric speciesOdontesthes smitti(Lahille, 1929)

Journal of Applied Ichthyology, 2009
In teleosts, testis organization can be classified in different morphological categories (Grier, 1993; Grier and Parenti, 1994). While primitive osteichthyans show anastomosed tubular testes, the derived teleost species (sensu Parenti and Grier, 2004) present one of two principal morphologies according to the type of distribution of spermatogonia ...

Embryonic and larval development of yellow perch (Perca flavescens) and its sensitivity to incubation temperature

Journal of Fish Biology, Volume 105, Issue 3, Page 735-751, September 2024.
Abstract The ontogenetic development in teleost fish is sensitive to temperature, and the developmental rate has a direct relationship with the environmental temperature within a species' thermal tolerance limit. Temperature determines time to and survival at hatching.

The Tissue‐Specific Eco‐Exposome: Differential Pharmaceutical Bioaccumulation and Disposition in Fish among Trophic Positions

Environmental Toxicology and Chemistry, Volume 43, Issue 8, Page 1894-1902, August 2024.
Abstract Though bioaccumulation of pharmaceuticals by aquatic organisms continues to receive scientific attention, the internal disposition of these contaminants among different tissue compartments of fish species has been infrequently investigated, particularly among fish at different trophic positions. We tested a human to fish biological read‐across

Modeling potential consequences of climate‐driven sex reversal on Southern and Summer Flounder population dynamics

Marine and Coastal Fisheries, Volume 16, Issue 2, April 2024.
Abstract Objective We investigate the interacting effects of fishery selectivity and sexual dimorphism by using the fisheries for Southern Flounder Paralichthys lethostigma and Summer Flounder P. dentatus as case studies. In both species, females are larger than males, and temperature‐sensitive sex determination can lead to an increased proportion of ...

Sedimentary evolution and lake level fluctuations of Urmia Lake (north‐west Iran) over the past 50 000 years; insights from Artemia faecal pellet records

Sedimentology, Volume 71, Issue 3, Page 887-911, April 2024.
Abstract A 25 m long sediment core from hypersaline Urmia Lake (north‐west Iran) was studied for the Late Quaternary depositional history and palaeoclimate variations using the abundance and compositional characteristics of Artemia faecal pellets. Sediment analysis is supported by scanning electron microscopy – energy dispersive X‐ray spectroscopy ...

Populations of Odontesthes (Teleostei: Atheriniformes) in the Andean region of Southern South America: body shape and hybrid individuals

Neotropical Ichthyology
The original distribution area of the Patagonian 'pejerrey' Odontesthes hatcheri has been subjected to the introduction of a related species; the Bonaerensean 'pejerrey' Odontesthes bonariensis. This species currently coexists with O.
