Distribution of ostracods in west-central Argentina related to host-water chemistry and climate: implications for paleolimnology [PDF]

open access: yes, 2017
Ecological and biogeographical studies of Neotropical non-marine ostracods are rare, although such information is needed to develop reliable paleoecological and paleoclimatic reconstructions for the region.

Acute toxicity of four metals to three tropical aquatic invertebrates: The dragonfly Tramea cophysa and the ostracods Chlamydotheca sp. and Strandesia trispinosa

open access: yesEcotoxicology and Environmental Safety, 2019
The relatively low availability of toxicity data for indigenous tropical species has often been discussed. In addition, several taxonomic groups of invertebrates are understudied, such as dragonflies and ostracods. The aim of the present study was therefore to evaluate the acute toxicity of four metals (cadmium - Cd, copper - Cu, manganese - Mn, and ...

Patrones demográficos en poblaciones naturales de Cyprididae (Crustacea: Ostracoda) del área rioplatense y sus respuestas vitales en bioensayos de toxicidad [PDF]

open access: yes, 2016
Los Ostracoda son microcrustáceos que se caracterizan por la presencia de un caparazón bivalvo de origen epidérmico y de cinco a ocho pares de apéndices. Su tamaño varía entre 0,3 - 5,0 mm promedio.

Postembryonic development of nonmarine ostracod Chlamydotheca arcuata (Sars, 1901) (Crustacea: Ostracoda), reared in the laboratory [PDF]

open access: yes, 2019
We describe here 8 instars (from A-8 through A-1) of the postembryonic development of the Cyprididae Chlamydotheca arcuata (Sars, 1901) from hatching to sexually mature individuals.

ECOLOGY OF NON–MARINE OSTRACODA FROM LA FE RESERVOIR (EL RETIRO, ANTIOQUIA) AND THEIR POTENTIAL APPLICATION IN PALEOENVIRONMENTAL STUDIES

open access: yes, 2010
El muestreo de las macrófitas asociadas a la zona litoral entre los meses de junio y septiembre de 2008 del embalse La Fe (El Retiro, Antioquia), permitió el reconocimiento de cuatro géneros y seis especies de ostrácodos no marinos pertenecientes a las ...

Species' traits and taxonomic distance can predict the hatching phenology of ostracod (Crustacea) resting eggs from tropical floodplain lakes

open access: yes, 2021
Freshwater ostracods are commonly found in temporary ponds and lakes, surviving drought periods by producing resting eggs. We investigated the hatching phenology of ostracod resting eggs from the sediments of temporary floodplain lakes, considering both ...

Late Quaternary lacustrine ostracods (Ostracoda, Crustacea) and charophytes (Charophyta, Charales) from the Puna Plateau, Argentina [PDF]

open access: yes, 2016
Relatively little is known about the recent palaeontological records of the high-altitude closed basin lakes of the Central Andes, but a great need exists to remedy this knowledge gap if microfossils are to be used to infer climatic and ecological ...

Ostracods of shallow lakes of the central region of Argentina: Paleolimnological implications [PDF]

open access: yes, 2017
Studies about ostracods in shallow lakes are very scarce in the Province of La Pampa, thus the objective of this work is to contribute to the knowledge of the species present in lentic environments, studying the distribution, abundance, and specific ...
