A Review on Heat Stress in Broiler Chickens: Mechanisms, Effects and Mitigation Strategies

open access: yesVeterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Heat stress caused by high temperature and humidity compromises broiler health, welfare, and productivity by reducing feed intake, growth performance, and feed efficiency, while increasing mortality, oxidative stress, metabolic disturbances, intestinal dysfunction, gut dysbiosis, immune suppression, and meat quality deterioration.

Diversity and prevalence of endoparasites in wild and feral Columbidae across urban and natural habitats

open access: yesParasitology
Pigeons and doves (Columbidae: Columbiformes) commonly inhabit urban and natural environments, where their close association with humans, domestic animals and wildlife facilitates environmental contamination and the transmission of parasitic infections ...

Prevalence and Associated Factors of Gastrointestinal Helminths Infection in Domestic Ruminants in and Around Gondar City, Northwest Ethiopia

open access: yesVeterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Gastrointestinal helminths were highly prevalent (56.5%) in domestic ruminants in and around Gondar city. The parasites were Strongyloides, Nematodirus, Trichuris, Fasciola, Paramphistomum, Moniezia and strongyle‐type nematodes, the latter being the most common.

Proteolytic enzymes and their inhibitors in cestodes

open access: yes, 2016
Complex physiological relationships between a parasite and its host are evidenced by the following facts. Cestodes are able to produce their own proteolytic enzymes or to adsorb and utilize host proteinases, on the one hand, secreting inhibitors of these

Marine flatworms as windows into the evolution of bilaterian neuropeptide signalling

open access: yesJournal of Neuroendocrinology, Volume 38, Issue 9, September 2026.
Abstract The evolutionary origin(s) of neuropeptide signalling is still largely unknown. It has been hypothesized that signal transmission via neuropeptides played a crucial role in the regulation of nervous systems in the bilaterian ancestor. Identification, expression and functional analyses of neuropeptides and their receptors across different ...

Vitellogenesis in two spathebothriidean cestodes

open access: yes, 2005
Spermiogenesis and sperm ultrastructure of adult Cyathocephalus truncatus, a member of presumably basal group of ‘‘true’’ cestodes (Eucestoda), have been examined for the first time by using transmission electron microscopy.

Do Parasite Effects on Fish Body Condition Depend on Host Size and External Temperature? A Meta‐Analytic Approach

open access: yesJournal of Zoology, Volume 330, Issue 1, Page 32-40, September 2026.
Evaluating relationships between host body condition indices (BCIs) and parasite infections is a common approach for assessing the negative effects of parasites on host health. Researchers generally expect negative correlations between BCIs and infection levels; however, empirical results are often highly variable among host–parasite systems.

Genotype–Phenotype‐Environment Associations and Potential Local Adaptation Signals in the Mesquite Lizard Along the Eastern Trans‐Mexican Volcanic Belt

open access: yesMolecular Ecology, Volume 35, Issue 18, September 2026.
ABSTRACT Anthropogenic activities modify the composition and configuration of landscapes and fragment habitats, generating environmental gradients and dispersal barriers that alter gene flow and generate selective pressures. Identifying local adaptation, which depends on the balance between selection and gene flow, requires integrative approaches that ...
