Zooplankton Diversity and Abundance in the Western Pacific Ocean [PDF]

Zooplankton plays a crucial role in marine ecosystems by linking primary producers, such as phytoplankton, to higher trophic levels. This study explains the relationship between zooplankton abundance and phytoplankton availability at different depths and

Stable Isotope Analyses of Yellowfin and Blackfin Tuna Eye Lenses Reveal Life History Patterns

Fisheries Oceanography, EarlyView.
ABSTRACT Spatial geography, ontogenetic movement, and trophic patterns of mobile species are key elements of species life history, and knowledge of them is critical for effective marine resource management. For yellowfin tuna (Thunnus albacares; YFT) and blackfin tuna (Thunnus atlanticus; BLFT), residency durations and ontogenetic movements in the Gulf

Community composition of zooplankton and macroinvertebrates of Chelekleka wetland, Ethiopia, and the seasonal visitation of greater flamingo (Phoenicopterus roseus)

Global Ecology and Conservation
Greater flamingos (Phoenicopterus roseus) are key species in wetlands and feed mainly on zooplankton and macroinvertebrates. Little is known about the zooplankton and macroinvertebrate communities of East African wetlands and the relationship with the ...

Under the cover of darkness: Foraging behaviour increases on cloudy, new moon nights in a pelagic seabird

Ibis, EarlyView.
While many visual predators feed exclusively during the day, others exploit foraging opportunities at night, although the efficiency with which they do so is strongly influenced by ambient light levels. We investigated the influence of variation in nocturnal light on the foraging behaviour of a small pelagic seabird, the European Storm‐petrel ...

The Impacts of Recently Established Fish Populations on Zooplankton Communities in a Desert Spring, and Potential Conflicts in Setting Conservation Goals

Diversity, 2015
Desert springs, which harbor diverse and endemic invertebrate assemblages, are often used as refuge habitats for protected fish species. Additionally, many of these springs have been colonized by invasive fish species.

Seasonal variation in preen gland secretions of Tristram's Storm Petrel (Hydrobates tristrami)

Ibis, EarlyView.
Preen gland secretions are known to vary depending on sex, season and species and are thought to play essential roles in avian life history. However, their chemical composition and functions remain largely unclear in Procellariiform seabirds with well‐developed olfactory senses. Storm petrels, known for their distinctive body odour, may use preen gland

Changes in abundance and diversity of zooplankton communities in the Nagy-Morotva oxbow lake

, 2019
Oxbow lakes are small and shallow water bodies and usually limited into a littoral zone due to favorable light conditions.The aim of this study was to investigate the zooplankton community in the Nagy-morotva oxbow lake.

Zooplankton fecal pellets as a vector transporting microplastics and associated toxins to the deep ocean

, 2022
Toxins within the fecal pellets of zooplankton were measured along a transect from Hawaii to San Diego, passing through the southern edge of the Great Pacific Garbage Patch.

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...
