Seasonal changes in the parasite prevalence of a small Malagasy lemur species (Lepilemur edwardsi)

open access: yesIntegrative Zoology, Volume 18, Issue 3, Page 427-439, May 2023., 2023
The folivorous Malagasy primate Lepilemur edwardsi living in the dry deciduous forests of western Madagascar shows a seasonal increase of intestinal parasite prevalence from the wet to the dry season. The increase in intestinal parasites is presumably caused by a decrease in resource availability and quality in the habitat of L. edwardsi. Ectoparasite (

Phylogenomic Analysis of the Phylum Nematoda: Conflicts and Congruences With Morphology, 18S rRNA, and Mitogenomes

open access: yesFrontiers in Ecology and Evolution, 2022
Phylogenetic relationships within many lineages of the phylum Nematoda remain unresolved, despite numerous morphology-based and molecular analyses. We performed several phylogenomic analyses using 286 published genomes and transcriptomes and 19 new ...

Contrasting seasonal patterns in diet and dung‐associated invertebrates of feral cattle and horses in a rewilding area

open access: yesMolecular Ecology, Volume 32, Issue 8, Page 2071-2091, April 2023., 2023
Abstract Trophic rewilding is increasingly applied in restoration efforts, with the aim of reintroducing the ecological functions provided by large‐bodied mammals and thereby promote self‐regulating, biodiverse ecosystems. However, empirical evidence for the effects of megafauna introductions on the abundance and richness of other organisms such as ...

Prevalence of Helminthic Infections in the Gastrointestinal Tract of Cattle in Mazandaran Province (Northern Iran)

open access: yesJournal of Parasitology Research, Volume 2022, Issue 1, 2022., 2022
Ruminant parasites are found in all parts of the world, including the tropical and subtropical regions. Mazandaran province (northern Iran) is one of the areas prone to the activity of gastrointestinal parasites in ruminants. This study was performed in 2020, in order to identify common parasites of cattle gastrointestinal tract, the percentage of the ...

A comparative analysis of spider prey spectra analyzed through the next‐generation sequencing of individual and mixed DNA samples

open access: yesEcology and Evolution, Volume 11, Issue 21, Page 15444-15454, November 2021., 2021
Individual DNA sample sequencing obtains the accurate prey spectrum of spiders. Mixed DNA sample sequencing underestimates the prey spectrum of spiders. Individual and mixed DNA sample sequencing obtains almost the same relative abundance of prey sequences of spiders.
