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

The complete mitogenome of the fairy shrimp Streptocephalus cafer (Lovén, 1847) (Crustacea: Branchiopoda: Anostraca) from an ephemeral pond in Botswana, southern Africa

open access: yesMitochondrial DNA Part B: Resources, 2020
Fairy shrimps (Anostraca) constitute an important component of seasonally aquatic habitats, but few complete mitochondrial genomes have been published for this group.

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,

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

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 ...

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 ...

Species composition of Sididae (Branchiopoda: Cladocera) in Vientiane Province and Vientiane City, Laos

open access: yes, 2020
The species composition of the Sididae (Branchiopoda: Cladocera) of Laos (Vientiane Province and Vientiane City) was studied, based on 52 samples from 28 localities. Five species were recorded, with the genus Diaphanosoma represented by three.

Novel Methods in Cladoceran Size Structure Analysis Reveal ~60 Years of Trophic Change in a Sediment Core From a Great Lakes Area of Concern (Bay of Quinte, Lake Ontario)

open access: yesFreshwater Biology, Volume 70, Issue 10, October 2025.
ABSTRACT Nutrient loading, aquatic invasive species, and climate warming have altered food web dynamics in the Great Lakes. Long‐term data are required to characterise the response of the lower food web to multiple environmental drivers and develop trophic indicators for future research and management efforts.

Using fecal DNA metabarcoding to investigate the animal diet of black rails, yellow rails, and soras

open access: yesWildlife Society Bulletin, Volume 49, Issue 3, September 2025.
We used fecal DNA metabarcoding to investigate the diet of yellow rails, Eastern black rails, and sora during the non‐breeding season. Arthropods, particularly ants, were prevalent in their diets, suggesting possible interactions with invasive red imported fire ants.
