An Uncommon Instance of Egyptian Blue in the “Pigmented Intonachino” of the Fishpond Wall Painting From the Roman Villa of Torre di Pordenone (Northeast Italy)

open access: yesArchaeometry, EarlyView.
ABSTRACT The increasingly close integration of analytical techniques in the study of Greek and Roman wall paintings has shown that Egyptian blue was a common pigment, widely documented in the production of blue and greenish hues in ancient painted production.

Spatial heterogeneity in exposure to Brucella suis and pathogenic leptospires in feral pigs across New South Wales

open access: yesAustralian Veterinary Journal, EarlyView.
Feral pigs (Sus scrofa) are important reservoirs for zoonotic and livestock pathogens in Australia, but robust information on the spatial distribution of pathogens in pig populations remains limited. We analysed serological data from a systematic, state‐wide surveillance program to investigate spatial heterogeneity in exposure to Brucella suis and ...

Anatomical and Histological Descriptions of the Male Reproductive System of the Alfalfa Weevil of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae) Using Light and Scanning Electron Microscopies

open access: yesActa Zoologica, EarlyView.
ABSTRACT Features of the reproductive organs, such as the number of testicular follicles, testis colour and the morphology of the glands, can be used as systematic characters. For this purpose, this paper was the first description of the male reproductive system anatomy and histology of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae), a ...

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

open access: yesBoreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

The collective application of shorebird tracking data to conservation

open access: yesConservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Physiological Host Range of the Tachinid Istocheta aldrichi, a Potential Biological Control Agent for the Japanese Beetle in Europe

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
This study provides the first laboratory assessment of the physiological host range of Istocheta aldrichi, a candidate biological control agent for Popillia japonica in Europe. In sequential no‐choice tests with 14 European scarab beetles, the parasitoid oviposited on six species but successfully developed only in the two Rutelinae Anomala vitis and ...

Wood Thrush (Hylocichla mustelina) occupancy patterns reveal sensitivity to low precipitation on nonbreeding grounds in northern Costa Rica

open access: yesIbis, EarlyView.
Climatic change and anthropogenic disturbances are reshaping animal populations. Habitat loss and extreme climatic events are particularly strong drivers of declines in species that depend on forested areas. For migratory songbirds, climate and the persistence of suitable habitat over time are fundamental to sustaining populations annually.

Declining habitat directive butterflies within a major stronghold: Challenges for conservation Rückläufige Tagfalter der FFH‐Richtlinie in einer bedeutenden Hochburg: Herausforderungen für den Naturschutz

open access: yesInsect Conservation and Diversity, EarlyView.
Myrmecophilous Phengaris nausithous and P. teleius are highly specialized grassland butterflies and flagship species for European nature conservation, but they exhibit ongoing population declines. We show strong declines for both species in the Westerwald mountain range, western Germany, since 1994, driven by inappropriate timing of mowing, grassland ...

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

Better Control With More Food: Continuous Provision of Alternative Food Enhances Thrips Control by Predatory Mites

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The use of alternative food has become an integral component of biocontrol, allowing the introduction and establishment of predators into a crop before pest invasion and sustaining populations even when pest densities are low. The addition of alternative food also has a positive long‐term effect in decreasing the densities of the pest.
