open access: yesЖивотновъдни науки, 2013
An investigation with 1929 sheep from the Caucasian Merino breed at different age, belonging to the Kabiuk was carried out. The effect of year of birth (A), breeding line (B) and mating scheme (C) on the traits wool yield, staple length, clean wool ...

A preventive strategy for the control of aphids in sweet pepper using lacewings and micrococcinelid beetles

open access: yesInsect Science, EarlyView.
Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

Climatic–Anthropogenic Synergy Drives Escalating Minimum Area Requirements and Connectivity‐Protection Mismatch in a Karst‐Endemic Primate

open access: yesIntegrative Zoology, EarlyView.
Climate change and anthropogenic activities drive antagonistic degradation of landscape connectivity for endangered François’ langur (1987–2024), causing 48.8% habitat loss, north‐south fragmentation, and centroid migration (1.2 km/yr). Despite protected areas buffering connectivity, static management fails dynamic priority habitats; we propose ...

Morphological and Morphometric Analysis of Animal Hair From 18th Century Burial Sites in Mazamet (Southwest France)

open access: yesArchaeometry, EarlyView.
ABSTRACT Morphological and morphometric analysis of archaeological animal hairs offers a nondestructive method to explore past clothing. We examined hair from two 18th‐century burial areas (SP03 and SP04) in Mazamet, France. SP03 specimens exhibited a continuous medulla, a low medullary index (0.2 ± 0.03) and cuticular features suggesting goat or ...

Evaluation of Crossbreeding Effects for Wool Traits in Sheep

open access: yesAsian-Australasian Journal of Animal Sciences, 2006
Crossbreeding effects for wool quality traits viz. greasy fleece weight (kg), staple length (cm), average fibre diameter (μ) and medulation percentage were estimated using the Dickerson's and Kinghorn's models. The data analyzed involved 15 genetic groups including Nali purebred, F 1 's of two and three breeds, F 2 's and reciprocal crossbred obtained ...

No escape from microplastics: Contamination of reef manta ray feeding areas in a remote, protected archipelago

open access: yesConservation Science and Practice, EarlyView.
We found microplastic contamination of the upper water column around the Chagos Archipelago, a remote, protected archipelago in the central Indian Ocean. Key aggregation areas for reef manta rays (Mobula alfredi) were contaminated, putting them at risk of microplastic ingestion.

Polymorphisms and association of FAT1 gene with wool quality traits in Chinese Merino sheep

open access: yesCzech Journal of Animal Science, 2020
FAT atypical cadherin 1 (FAT1) is a member of the atypical cadherin superfamily and is involved in the planar cell polarity signalling pathway which regulates hair follicle morphogenesis, cycling, and orientation.

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

open access: yesEcological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.
