Internal ultrastructure of the planktonic larva of the coral Porites panamensis (Anthozoa: Scleractinia)
Rev. biol. trop; 70 (1), 2022
Abstract Introduction: The scleractinian coral life cycle includes planktonic larvae that settle on the benthos, allowing the primary polyp to clone and build a sexually reproducing adult colony. The larval physiology and ecology of Eastern Tropical Pacific scleractinians needs the exploration of basic a...
Spatio-temporal variability in the Cladocera assemblage of a subtropical hypersaline lagoon
Braz. j. biol; 82 (), 2022
Cladocera represent an important zooplankton group because of their seasonal prominence in terms of abundance and their contribution in controlling primary production (phytoplankton). On a global scale, there are few studies on Cladocera in hypersaline environments. The present work aims to evaluate the ...
Daily vertical distribution of zooplankton in two oligo-mesotrophic north Patagonian lakes (39° S, Chile)
Braz. j. biol; 81 (3), 2021
Abstract The zooplankton communities often exhibit daily vertical migrations to avoid natural ultraviolet radiation and/or fish predation. However there is no information on this topic in Chilean North Patagonian lakes up to date. Therefore, this study deals with a first characterization of plankton crus...
Profile of host cell responses to exposure to stressed bacteria in planktonic; dislodged, and intact biofilm mode
Braz. dent. j; 32 (3), 2021
Abstract The host defense response to microbial challenge emerging from the root canal system leads to apical periodontitis. The aim of this study was to evaluate the expression of inflammatory cytokines and Nitric Oxide (NO) by macrophages after interaction with Enterococcus faecalis in the: plankton an...
Problems and puzzles in echinoderm demography
Rev. biol. trop; 69 (supl. 2), 2021
Introduction: There are problems and puzzles in understanding reproduction, growth and mortality in echinoderm life cycles. Objective: Explore problems and puzzles in life cycles that are important and challenging. Methods: The literature is used to elucidate problems associated with all life stages. Res...
Spatio-temporal Distribution Pattern of Oyster Larvae in Guaratuba Bay, Paraná State - Brazil
Braz. arch. biol. technol; 64 (), 2021
HIGHLIGHTS Crassostrea oysters larvae patterns in estuarine environments. Larvae distribution patterns in Guaratuba Bay (Paraná State - Brazil)....
Heterotrophic flagellates (Amorpha and Diaphoretiches) in phytotelmata bromeliad (Bromeliaceae)
Braz. j. biol; 80 (3), 2020
Abstract Many plants may accumulate rainwater, forming phytotelmata, aquatic microhabitats inhabited by various organisms. The aim of this study was to conduct an inventory of heterotrophic flagellates associated with phytotelmata of the bromeliad Aechmea distichantha Lem., found in rocky cliffs on the U...
Composición, densidad y distribución de los poliquetos planctónicos (Phyllodocida: Tomopteridae) en el Domo Térmico de Costa Rica, Pacífico Tropical Oriental
Rev. biol. trop; 68 (supl 2), 2020
Introducción: Los tomoptéridos son poliquetos holopelágicos ampliamente distribuidos en todos los océanos, sin embargo, han sido pobremente estudiados, a pesar de sus importantes implicaciones en las redes tróficas como depredadores de varios grupos de animales de la comunidad del plancton, incluyen...
Aerial plankton from the Eastern Tropical Pacific
Rev. biol. trop; 68 (supl 2), 2020
Introduction: Small terrestrial invertebrates disperse in a passive manner through wind currents, forming what is known as aerial plankton, which has not been surveyed yet for the Eastern Tropical Pacific. Documenting the aerial plankton of Isla del Coco will allow to better understand the colonization p...
