Methodology for assessing the suitability of immature stages of Lepidoptera for nocturnal surveying using ultraviolet flashlights

open access: yesEcological Entomology, EarlyView.
Lepidoptera are highly sensitive to changes in their surroundings, making them excellent indicators of ecosystem health; however, surveying adult butterflies of certain species presents challenges. Nocturnal surveying of larvae and pupae using ultraviolet light (UV) is gaining popularity as a simple, inexpensive, and non‐invasive method.

Can you really change your stripes? Stable wing ornamentation suggests limited condition‐dependent signalling in female common eiders

open access: yesIbis, EarlyView.
Variation in the expression of white ornaments, such as flank spots or wing stripes, has previously been related to indices of individual quality in birds. We measured the white wing stripes of colour‐banded female common eiders Somateria mollissima in three islands in Iceland from 2014 to 2023, to determine whether the expression of these ornaments is

Beyond the breeding grounds: identifying post‐breeding staging areas, corridors and ecological niche of the Lesser Kestrel

open access: yesIbis, EarlyView.
The post‐breeding period is a critical yet overlooked phase in the annual cycle of migratory birds, where individuals must resolve competing bioenergetic trade‐offs between recovery from breeding, moult and migratory fuelling. Using GPS data from 54 adult Lesser Kestrels Falco naumanni tracked across Spain, we analysed 76 post‐breeding tracks to ...

A systematic review and meta‐analysis of variation in nest predation of ground‐nesting birds

open access: yesIbis, EarlyView.
Predation and communities of predators of ground‐nesting bird nests and fledglings have been studied across multiple groups of ground‐nesting birds, such as waders, waterbirds, gamebirds and passerines, and habitats, but differences and similarities between groups are less studied.

Transcriptomic and proteomic signatures underlying nymphal adaptation and foam production in the forage pest Mahanarva spectabilis

open access: yesInsect Molecular Biology, EarlyView.
RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...

Differential Varietal Responses in Faba Bean Concerning Pea Aphid and Pea Necrotic Yellow Dwarf Virus (PNYDV) When Intercropped With Oat

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The pest status of pea aphid (Acyrthosiphum pisum H.) in faba bean (Vicia faba L.) cultivation has gained importance because it transmits Pea necrotic yellow dwarf virus (PNYDV), a novel nanovirus in Europe. This study evaluated two faba bean varieties, ‘Fuego’ and ‘GL Sunrise’, grown under sole crop (SC) and intercrop (IC) conditions with oat

Depredation of Livestock by Wild Carnivores in the Eastern Serengeti Ecosystem, Tanzania

open access: yes, 2017
Globally, wild carnivore populations outside protected areas are at threat from retaliatory killings triggered by livestock depredation. Monitoring of livestock depredation in specific areas is essential to formulate conflict management strategies that can address the root causes of human carnivore conflicts and promote wild carnivore conservation ...
