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

open access: yesJournal 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?

open access: yesEcosphere, 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

VIII. On the feeding mechanism of the Branchiopoda [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series B, Containing Papers of a Biological Character, 1932
Abstract Introduction . In Lankester’s classical essay (1881) on the appendages of Apus he defines the proximal endite of the trunk limb as a “ gnathobase,” stating th at “ it is a jaw process ” and clearly has the function of assisting, by means of apposition to its fellow of the opposite side, in seizing and moving particles which ...

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

open access: yesJournal 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 ...

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

open access: yesActa 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

open access: yesFreshwater 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,

Zooplankton Community Composition in the White and Blue Niles Near Khartoum: Combining Molecular and Morphological Approaches

open access: yesEnvironmental DNA, Volume 7, Issue 6, November–December 2025.
Environmental DNA (eDNA) metabarcoding of bulk zooplankton from the White and Blue Nile near Khartoum recovered 40 genus/species‐level taxa belonging to Cladocera, Copepoda, and Rotifera, representing 53%–72% of ASVs. Rotifers were the most diverse group, and low Cladocera read counts likely reflect primer mismatch despite similar morphological ...
