Fluctuation and diversity of Hydromedusae (Hydrozoa, Cnidaria) in a highly productive region of the Gulf of Mexico inferred from high frequency plankton sampling [PDF]

PeerJ, 2019
Hydrozoa medusae undergo blooms and seasonal fluctuations; however the drivers of such fluctuations are unknown. To understand how medusa populations fluctuate in response to seasonal factors such as temperature, salinity, dissolved oxygen, and ...

Spatial Segregation and Trophic Niche Divergence in Two Disjunct Populations of Wedge‐Tailed Shearwater Ardenna pacifica in Eastern Australia

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study investigated habitat use and trophic niche differentiation in two wedge‐tailed shearwater populations in eastern Australia (2015 to 2019). Temperate birds foraged mainly in southeastern Australian waters and undertook a pre‐staging detour towards the subtropical frontal zone before migration, whereas subtropical birds foraged further east ...

Environmental DNA Reveals Diverse and Depth‐Stratified Biodiversity in East Indian Ocean Submarine Canyons

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Environmental DNA metabarcoding reveals diverse animal communities across Cape Range and Cloates submarine canyons off Western Australia. Two assays detected 234 species spanning 125 families across 11 phyla, highlighting canyon‐specific assemblages and demonstrating the value of eDNA for establishing biodiversity baselines in remote and poorly ...

Exploring the Diversity of Temperate Mesophotic Rocky Reefs From ARMS and Water eDNA in Central Chile

Environmental DNA, Volume 8, Issue 2, March/April 2026.
LowerMesophoticEcosystems have greater alpha diversity and number of exclusive families, high turnover between LowerME and UpperME with clear differences in community composition. Water eDNA and ARMS eDNA are characterized by pelagic and benthic affinity respectively.

Brazil's Invisible Invaders: Are Craspedacusta Jellyfish a Ticking Ecological Bomb?

Austral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT The invasive freshwater jellyfish Craspedacusta sowerbii, likely of Asian origin, is globally distributed, yet its invasion history in South America remains poorly understood. Following a mass mortality event of tilapia (Oreochromis niloticus) during a jellyfish bloom in Paraná, Brazil, in March 2022, we conducted morphological and molecular ...

Critical knowledge gaps in the conservation and restoration of cold‐water corals

Restoration Ecology, Volume 34, Issue 3, March 2026.
Abstract Introduction Critical knowledge gaps hamper effective conservation of threatened cold‐water coral (CWC) ecosystems, facing cumulative anthropogenic and climate pressures. This review provides a strategic roadmap for urgent, informed intervention.

The Critical Role of Coefficients: Updating Allometric Normalisation Constants for Modern Ecology and Modelling

Ecology Letters, Volume 29, Issue 2, February 2026.
Allometry is central to a wide range of ecological research including dynamic food web modelling. Here we updated the often neglected allometric coefficients for metabolism and production, deriving new genus and metabolic group levels estimates with phylogenetic hierarchical modelling providing robust inference.

eDNA Metabarcoding Reveals Microbial Community Composition in Tropical Mangrove Forests in Makassar, Indonesia

Ecology and Evolution, Volume 16, Issue 1, January 2026.
This study used environmental DNA (eDNA) metabarcoding with 18S rRNA markers to assess microbial diversity in the Lantebung Mangrove Forest, Makassar, Indonesia. It identified 103 microbial species across five kingdoms, revealing higher species richness in open‐water areas (P1) and greater individual abundance under mangrove canopy (P2).

Environmental DNA as a Tool for the Assessment of Coral (Anthozoa) Composition in the Chagos Archipelago

Environmental DNA, Volume 8, Issue 1, January–February 2026.
Environmental DNA (eDNA) metabarcoding using ITS2 markers reliably recovered 18 coral genera, with strong overlap but also complementary detections compared to benthic transect surveys. eDNA uniquely identified several cryptic genera, while some common genera were only recovered by traditional surveys, highlighting method‐specific biases.

Orientiertes Wachstum beiMillepora dichotoma (Hydrozoa) [PDF]

Helgoländer Wissenschaftliche Meeresuntersuchungen, 1974
1. An der Westkuste des Golfes von Akaba wurde an 3 verschiedenen Probeorten die Facherorientierung vonMillepora dichotoma untersucht, wobei jede Probenflache aus drei gleichgrosen Teilflachen bestand. Die Tiefenausdehnung des Transekts wurde durch die Tiefenbegrenzung der Milleporiden bestimmt. 2.
