Macroecological relationships provide insights into rules that govern ecological systems. Bergmann's rule posits members of the same clade are larger at colder temperatures. Whether temperature drives this relationship is debated because several other potential drivers covary with temperature. We conducted a near‐global comparative analysis on marine copepods (97 830 samples, 388 taxa) to test rule, considering drivers. Supporting we found better predicted size than did latitude or oxygen,...
Introduction: Zooplankton is a major link between primary producers and the following trophic levels, in coral reefs they represent an energy source for corals involve complex assemblies integrating wide variety of species form different functional groups. Objective: To define interannual changes zooplankton Isla del Coco. Methods: Three system were sampled. Two or three samples taken by surface horizontal trawls each reef from 2009 to 2012, using conical nets 200 500 µm mesh sizes at times...
Abstract Zooplankton is the main food source for higher trophic levels in marine environments. In Southern Ocean, distribution of zooplankton related to physical gradient Antarctic Circumpolar Current (ACC) fronts. Our objective was determinate mesozooplankton relation ACC fronts Drake Passage. Samples were collected with Continuous Plankton Recorder two transects. Mesozooplankton associated environmental variables. High abundances recorded Subantarctic Front 2017 and Zone 2016. A total 81...
Introduction: Zooplankton is a major link in coral reef food webs and source of nutrients for corals. Demersal zooplankton reefs makes diel migrations at night to avoid predation by fish corals, increasing abundance biomass night. Objectives: To study the composition variation demersal pelagic community increase taxonomic knowledge benthic copepod fauna over different substrates reef. Methods: Traps made plastic, with 100 μm mesh size collector cup attached, were placed 12 hours between 5-10...
Zooplankton in small tropical lakes has been little studied and its variation during the year may respond to different factors. In this study, zooplankton of a neotropical lake was at times one compared with changes conditions phytoplankton composition. The stratifies from March until September, mixes hemispherical winter, October February. Besides show seasonal fluctuation water level according seasonality rains. composed least 13 species, four Cladocerans, three Copepods, Rotifers other...
During a survey of the epipelagic zooplankton Isla del Coco, an oceanic island off coast Costa Rica, eastern tropical Pacific, female and male specimens pontellid calanoid copepod belonging to genus Pontella were collected. It was recognized as undescribed species fera species-group. is most closely related P. tenuiremis Giesbrecht, 1889 Dana, 1849. The new species, cocoensis, can be distinguished from these other congeners by having unique combination characters including: 1) genital...

This review summarizes marine zooplankton research performed in the Costa Rican Pacific and Caribbean coasts at Isla del Coco National Park. Composition, abundance, biomass, distribution some ecological features of for each system is discussed. coastal composition has been described Bahía Salinas Culebra. The local oceanography these bays heavily influenced by Papagayo wind jet, which produces seasonal upwelling most likely drives changes abundance biomass. Copepods ostracods were dominant...
