Global Variation in Zooplankton Niche Divergence Across Ocean Basins
Ecology Letters, Volume 28, Issue 2, February 2025.We explored the evidence of niche divergence between population for marine zooplankton globally. We found 44% of all population comparisons show niche divergence. Niche divergence varied across temperature and bathymetry gradients for copepods. ABSTRACT Modelling responses to climate change assumes zooplankton populations remain similar over time with ...

Logistic density-dependent growth of an Aurelia aurita polyps population
, 2014 We show in this paper that the dynamics of an Aurelia aurita polyps population can be modeled by the basic density-dependent logistic, or Verhulst, ordinary differential equation. A laboratory experiment was conducted on polyps of A.

Impacts of climate‐related stressors on social group cohesion and individual sociability in fish
Biological Reviews, Volume 99, Issue 6, Page 2035-2059, December 2024.ABSTRACT Group‐living in animals comes with a number of benefits associated with predator avoidance, foraging, and reproduction. A large proportion of fish species display grouping behaviour. Fish may also be particularly vulnerable to climate‐related stressors including thermal variation, hypoxia, and acidification.

Юг России: экология, развитие, 2020 Aim. The aim of the study is to find out what external factors may be the driving force behind the growth and population dynamics of two ecologically similar species of gelatinous macroplankton (scyphomedusa Aurelia aurita and ctenophore Pleurobrachia ...

Environmental DNA, Volume 6, Issue 6, November–December 2024.We assessed eDNA metabarcoding from surface water, bottom water, and sediment as well as zooplankton metabarcoding for their applicability to identify the known decline in invertebrate diversity along salinity gradients. All approaches identified regional communities, but with varying explanatory power, with none of these methods being able to ...

, 2014 The influence of copepod prey size and behaviour upon Aurelia aurita medusae predation rates was investigated. There was no significant difference in predation rates across a 4-fold (250 to 987 mm) prey size range (heat-killed developmental stages of ...

Journal of Fish Biology, Volume 105, Issue 5, Page 1406-1420, November 2024.Abstract Seasonal differences in the availability of resources potentially result in the food web architecture also varying through time. Stable isotope analyses are a logistically simple but powerful tool for inferring trophic interactions and food web structure, but relatively few studies quantify seasonal variations in the food web structure or ...

Ecological and acoustic investigations of jellyfish (Scyphozoa and Hydrozoa)
, 2008 As the biomass of jellyfish (medusae of the Scyphozoa and Hydrozoa) has risen in numerous locations worldwide, awareness of their potential to exert a controlling influence on marine ecosystems and hinder the recruitment of fish stocks has increased ...

Morphology, fluid Motion and Predation by the Scyphomedusa Aurelia Aurita
, 1994 Although medusan predators play demonstrably important roles in a variety of marine ecosystems, the mechanics of prey capture and, hence, prey selection, have remained poorly defined.
