Spectral Characterization of the Life Stages and Physiological Responses of Diatraea saccharalis Fabricius (Lepidoptera: Crambidae) Larvae Parasitized by Cotesia flavipes Cameron (Hymenoptera: Braconidae)

Entomologia Experimentalis et Applicata, EarlyView.
Hyperspectral proximal sensing was used to characterize the life stages and physiological responses of Diatraea saccharalis and to detect parasitism by Cotesia flavipes. Distinct spectral signatures differentiated eggs, larval instars, pupae, and adults, as well as live, dead, and parasitized larvae.

Technologies for equine welfare and performance monitoring under field conditions – Where do we stand?

Equine Veterinary Journal, EarlyView.
Abstract The need for comprehensive equine welfare assessments has become particularly evident amid ongoing debates about the social licence to operate in equestrian sports. During exercise, multiple physiological systems, principally the cardiovascular, respiratory, muscular, thermoregulatory, endocrine, and locomotory systems, undergo complex ...

Free‐living Black‐tailed Godwits maintain constant intake rates across varying grassland habitat conditions by adjusting their foraging behaviour

Ibis, EarlyView.
Free‐living birds need to acquire enough food to fulfil their energetic needs, which may require more effort in habitats with less favourable conditions. Therefore, to maintain their necessary energy intake, birds need to adjust their foraging behaviour in response to varying habitat conditions.

Behavioural and fitness effects of experimental immune activation during incubation in a wild passerine

Ibis, EarlyView.
Incubation is vital for avian embryo development but demands significant parental investment, potentially at the cost of self‐maintenance and immune function. For example, the acute phase response (APR), a systemic reaction against inflammation, infection or tissue injury, can trigger sickness behaviours such as reduced activity and foraging.

Environmental correlates of spatio‐temporal patterns of colour variation in a bird of prey: The common buzzard (Buteo buteo)

Ibis, EarlyView.
High colour variability in animals has been associated with adaptability to environmental change. Establishing how such variability is distributed in time and space, and identifying environmental correlates, can help understand the processes driving it.

Combining δ2H and δ34S stable isotopes identifies diverse moult strategies in a short‐distance migratory bird

Ibis, EarlyView.
Moult strategies in birds can vary considerably even within a single species, particularly in terms of where moulting takes place. Yet, the factors underlying this variation and its consistency across years and individuals remain poorly understood. One such strategy, moult migration, involves individuals moving to a specific moulting location amid ...
