Additional notes on Clathrozoella drygalskii (Vanhöffen, 1910) (Cnidaria, Hydrozoa)

open access: yesScientia Marina, 2000
Study of the material of Clathrozoella drygalskii (Vanhöffen, 1910), a hydroid initially referred to the thecate hydroids but probably better classified in athecate hydroids along with such families as Hydractiniidae and Solanderiidae, has been continued

Trophic Niche Overlap Between the Invasive Crab Rhithropanopeus harrisii (Gould, 1841) and Native Crab Species in the Southwest Atlantic Coast

open access: yesMarine Ecology, Volume 47, Issue 3, May/June 2026.
ABSTRACT The introduction of exotic species is one of the main drivers of biodiversity loss in aquatic ecosystems. The Harris mud crab Rhithropanopeus harrisii, native to the Atlantic coast of North America, was recorded in the Patos Lagoon estuary (southern Brazil) in the 1980s, likely introduced via ballast water. However, the effects of this invader

Approaches to the ethology of hydroids and medusae (Cnidaria, Hydrozoa)

open access: yesScientia Marina, 2000
The behavioural patterns of 26 species of Antho- and Leptomedusae (with or without medusa stage) were investigated by video recordings. The analysed activities were: answers to mechanical stimuli, prey capture and ingestion, digestion, egestion, and ...

Genomics of Caddisfly (Insecta: Trichoptera) Species Associated With Terrestrial Habitats

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Species of Limnephilidae (tube case making caddisflies (Trichoptera)) occur across a wide range of habitats, from cold headwater streams to stagnant pools to even terrestrial environments. We present high‐quality genome assemblies and annotations from two species that are associated with terrestrial environments: Enoicyla pusilla (Burmeister, 1839) and

Evaluating the possible role of bottom currents and internal waves in shaping seafloor morphology in a mesophotic reef

open access: yesSedimentology, Volume 73, Issue 3, Page 593-619, April 2026.
ABSTRACT Mesophotic reefs are located in low light conditions which, depending on the region, are usually found in water depths greater than ~30 m. They are less affected by ocean warming than reefs found in shallower water depths and thus might become increasingly important for the sustainability of marine biodiversity.

ECOLOGICL ASPECTS OF THE MORPHODYNAMICS OF SOME HYDROZOA [PDF]

open access: yesAmerican Zoologist, 1965
The specific architecture of a Hydroid polyp or a colony is, morphologically speaking, not a stable entity, because it is subjected to an incessant turnover and renewal at both cellular and higher levels. A continuous morphogenetic activity is in many cases (e.g., Hydra ) necessary for the maintenance of the shape and size of the individual polyp ...

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

open access: yesEcology 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 ...

Photosynthetic planulae and planktonic hydroids: contrasting strategies of propagule survival

open access: yesScientia Marina, 2000
Settlement delays can be important to prevent propagule waste when proper settling substrates are not immediately available. Under laboratory conditions, the planulae of Clytia viridicans underwent two alternative developmental patterns.

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

open access: yesEnvironmental 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 ...
