The Development of Phyllopodous Limbs in Leptostraca and Branchiopoda [PDF]

Journal of Crustacean Biology, 2009
Abstract We present a comparison of the development of trunk limbs in Nebalia sp. (Leptostraca) and Limnadopsis parvispinus (Branchiopoda). The overall correspondence in specific developmental steps and morphology, e.g., size and orientation of limb anlagen, plus the resulting interpretation of adult limb part homologies lead to the suggestion that ...

Spatial habitat partitioning enables coexistence of three Gobiidae species in estuarine environments

Journal of Fish Biology, Volume 108, Issue 2, Page 635-647, February 2026.
Abstract This study examines resource partitioning (feeding morphology, diet and habitat partitioning) among three gobiid species, the Knysna sandgoby Psammogobius knysnaensis, the prison goby Caffrogobius gilchristi and the river goby Glossogobius callidus, within an estuarine environment.

Fairy Shrimp (Branchiopoda: Anostraca) of Chile [PDF]

Journal of Crustacean Biology, 2008
Abstract Portions of Chile were surveyed for Anostraca. Including the two species of Artemia previously reported from Chile, we found 5 new localities and range extensions for 5 species of Branchinecta. Previous studies on Chilean Anostraca have focused on Artemia, and although Branchinecta was previously reported in Antarctica close to Chilean Air ...

Detection and succession properties of forested vernal pools with eDNA metabarcoding

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
We examined the capacity of environmental DNA metabarcoding for studying biodiversity of forested vernal pools, using multiple assays to investigate different eukaryotic communities over space and time. Our results suggest that metabarcoding can serve as a complementary tool for ‘scaling up’ vernal pool biodiversity monitoring, illuminating ecological ...

Phylogeny and Biogeography of Spinicaudata (Crustacea: Branchiopoda).

Zoological studies, 2020
Spinicaudata (spiny clam shrimp) is a taxon of Branchiopoda occurring since the Devonian and today it occurs nearly globally in temporary water bodies. We present the most species-rich phylogenetic analyses of this taxon based on four molecular loci: COI, 16S rRNA, EF1α and 28S rRNA.

First record and morphological features of Hemidiaptomus (Occidodiaptomus) ingens (Gurney, 1909) (Copepoda Calanoida) in Italy

Journal of Limnology, 2004
During a survey, carried out to assess the consistency of microcrustacean fauna inhabiting temporary ponds in Sicily, Hemidiaptomus (Occidodiaptomus) ingens (Gurney, 1909), a large calanoid copepod up to now known only for North-African ponds, Camargue ...

Factors affecting intraspecific diet variation of ducklings: Niche partitioning in a heterogeneous landscape?

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Variability in resource use within populations of free‐ranging animals can influence demographic and evolutionary processes. Yet in many ecological systems, the extent of intra‐population variation in the resources that animals consume and the environmental factors that contribute to this variance remain poorly understood. For example, dietary

First Record of Kurzia media (Birge 1879) (Cladocera: Chydoridae) in Brazil with notes on the holotype [PDF]

Acta Amazonica
The genus Kurzia, initially described in 1894 by Dybowski and Grochowski, has a worldwide distribution and includes eight species. In Brazil, Kurzia polyspina is so far the only species considered valid. Here we report the first record of Kurzia media in

Ecological and Genetic Insights Into Antarctic Fairy Shrimp, Branchinecta gaini Daday, 1910 (Branchiopoda: Anostraca) Populations on King George Island, Antarctica

Freshwater Biology, Volume 70, Issue 12, December 2025.
ABSTRACT The Antarctic fairy shrimp (Branchinecta gaini) is the largest inland animal in Antarctica and a key component of its freshwater ecosystems. Despite its broad distribution, little is known about its population structure, habitat tolerance, and potential vulnerability to climate change. This study investigated the occurrence, genetic structure,

Large branchiopods (Branchiopoda: Anostraca, Notostraca and Spinicaudata) from the salt lakes of Algeria

Journal of Limnology, 2006
We conducted a survey of large branchiopods (Crustacea, Branchiopoda) of the major salt lakes of Algeria, particularly those of the eastern Hauts Plateaux.
