Biodiversity, spatial, and seasonal distribution of the zooplankton community in semi-intensive fish farms in Rondônia state, Brazil

Boletim do Instituto de Pesca
In this study we determined the spatial and seasonal distribution (rainfall and drought) of the zooplankton community in 30 fish farms in the microregions of Vale do Jamari and Central-East of Rondônia.

Holocene Bythocytheridae (Ostracoda: Podocopida) from Southwestern Atlantic deep-sea sediments off Brazil. Part 1: tribes Bythocytherini Sars, 1926 and Jonesini Schornikov, 1981 [PDF]

Nauplius
The Bythocytheridae Sars, 1866 is one of the oldest families of cytheroidean Ostracoda, with a fossil record dating back to the Silurian. During the Cenozoic this family became one of the main constituents of the deep-sea ostracod faunas, with some taxa ...

Diet of juvenile skipjack herring Alosa chrysochloris: Ontogenetic shifts, predator–prey size ratios and mouth gape allometry

Journal of Fish Biology, EarlyView.
Abstract The skipjack herring Alosa chrysochloris inhabits Gulf of Mexico drainages, primarily the Mississippi River Basin, and estuarine environments in the Gulf of Mexico. The trophic ecology of the skipjack herring is poorly understood, therefore we quantified the length, mouth gape and gut contents of juvenile skipjack herring from the Mississippi ...

Search for Bioindicators of Pollution in the Guanabara Bay: Integrations of Ecologic Patterns [PDF]

Anuário do Instituto de Geociências, 2003
Guanabara Bay, since its discovery, has largely changed with the human occupation causing large amounts of deposited sediment and waste, as well as domestic and industry sewage. Surface sediment was analysed for foraminifera and ostracoda distribution,

Individual and combined effects of shading and habitat complexity on benthic macroinvertebrate communities in a mesocosm stream experiment (São Paulo, Brazil)

Restoration Ecology, EarlyView.
Abstract Introduction Agricultural activities are a major driver of biodiversity loss and ecosystem degradation in subtropical streams, often altering macroinvertebrate community structure and associated ecosystem functions. Although restoration strategies increasingly target these impacts, the relative importance of riparian shading and in‐stream ...

Towards objectivity in Ostracoda species definition

BSGF - Earth Sciences Bulletin, 2020
The problem of consistent identification of unornamented fossil ostracod taxa, especially species, is reviewed in an historical context. The solution lies in modern imaging and image storage and handling technologies combined with a careful but pragmatic

Profundum solomoni (Amphipoda: Uristidae) Exhibits a Disjunct Geographic Distribution at Hadal Depths Across the San Cristobal Trench, Santa Cruz Trench and Nova Canton Trough

Zoologica Scripta, EarlyView.
ABSTRACT Hadal environments (> 6000 m ocean depths) are often viewed as isolated locations with high species endemism due to limited dispersal. However, molecular studies continue to reveal greater complexity that questions historical perceptions. Recent population genetic studies focused on scavenging amphipods have identified broadly distributed ...

The first known troglomorphic, eyeless spider wasp (Hymenoptera: Pompilidae): Troglopompilus miracaecatus gen. et sp. nov. from the Nullarbor Caves, Western Australia

Austral Entomology, Volume 65, Issue 2, May 2026.
Abstract Surveys of caves of the Nullarbor Plain, Western Australia, revealed a remarkable assemblage of exceptionally well‐preserved mummified arthropods, comprising Araneae, Blattodea, Coleoptera and Chilopoda, all of which exhibit high levels of troglomorphism, lacking eyes and showing a number of other adaptations.
