Differentiation in reproductive traits of geminatemangrove crabs of the genus Aratus (Decapoda: Brachyura)across the Central American Isthmus
Rebolledo Navarro, Adriana Pacieli; Wehrtmann, Ingo S. (2016)The mangrove crab Aratus pisonii was considered to have an amphi-American distribution; however, a recent study revealed that the Eastern Tropical Pacific populations were genetically distinct, thus representing a new ... -
Distribution and reproduction of Ambidexter panamense and Palaemonetes schmitti in Pacific Costa Rica (Crustacea, Decapoda)
Wehrtmann, Ingo S. (1990)Este constituye el primer registro de las especies de carídeos P. schmitti y A. panamense para Costa Rica. Adultos de ambas especies fueron colectados en el estero de Punta Morales, Golfo de Nicoya, de enero a diciembre ... -

(2017)Echinoderms within the Eastern Tropical Pacific have mainly been studied in association with coral reefs. Investigations on echinoderms associated with soft-bottoms and estuaries are still scarce. The present study reports ... -
Effects of temperature on the embryonic development and hatchling size of Betaeus emarginatus (Decapoda: Caridea: Alpheidae)
Wehrtmann, Ingo S.; López, Gastón A. (2003)Betaeus emarginatus is an alpheid shrimp inhabiting rock pool environments characterized by strong fluctuations of ambient factors. Here we describe the embryonic development of B. emarginatus, and analyse the effects of ... -
Elasmobranch bycatch associated with the shrimp trawl fishery off the Pacific coast of Costa Rica, Central America
Clarke, Tayler McLellan; Espinoza Mendiola, Mario; Ahrens, Robert N. M.; Wehrtmann, Ingo S. (2015)Demersal sharks and rays are common yet vulnerable components of the bycatch in tropical bottom-trawl fisheries. Little is known about the elasmobranch assemblages associated with most of these fisheries, particularly ... -
Estructura poblacional y zonal potenciales de crianza del pargo mancha Lutjanus guttatus (Steindachner, 1869) en la costa del Pacífico de Costa Rica, a través de la composición isotópica de oxígeno (δ 18O) en otolitos
Farías Tafolla, Beatriz (2023)El pargo mancha Lutjanus guttatus se distribuye a lo largo del océano Pacífico, desde el norte de México hasta Perú y es una de las especies más abundantes en las zonas tropicales. A pesar de ser un recurso social y ... -
Feeding ecology of common demersal elasmobranch species in the Pacific coast of Costa Rica inferred from stable isotope and stomach content analyses
Espinoza Mendiola, Mario; Munroe, Samantha E. M.; Clarke, Tayler McLellan; Fisk, Aaron T.; Wehrtmann, Ingo S.
