Causes of mortality in koalas autopsied at the University of Melbourne
Australian Veterinary Journal, EarlyView.Objective To determine the causes of mortality in koalas autopsied at the University of Melbourne based on the retrospective analysis of autopsy reports. Methods The autopsy reports of 239 koalas examined at the University of Melbourne from 1970 to 2023 were reviewed to determine which of the comorbidities present was the primary cause to which death ...

In Vitro and In Vivo Effect of Amitraz on Honey Bee Drone Sperm Quality
Acta Zoologica, EarlyView.ABSTRACT Honey bee hive infestation by the ectoparasitic mite, Varroa destructor, has been a major cause of declining populations. Treating such infestations is important for sustainability. Knowledge about the sub‐lethal effects of commonly used acaricides on drone reproductive health, particularly sperm quality, is limited. The effect of in vitro and

Exploiting Nest Defense Behavior of Hosts: A Case Study of Successful Parasitism by a Common Cuckoo [PDF]
Ecol EvolWe document the case of a common cuckoo (Cuculus canorus) successfully locating and parasitizing the nest of a gray bush chat (Saxicola ferreus) by exploiting the latter's nest defense behavior. Our findings offer a new perspective for further exploring the behavioral strategies of parasitic birds and the evolutionary dynamics of the host's nest ...

Relevance of state–behaviour feedbacks for animal welfare
Biological Reviews, EarlyView.ABSTRACT An animal's behaviour and its state, including its health and affective state, are dynamic and tightly coupled, influencing each other over time. Although both are relevant to the animal's welfare, there has been limited research on their dynamics in welfare studies. Here we aim to: (i) review evidence for feedbacks between state and behaviour

The evolution of reproduction in Ediacaran–Cambrian metazoans
Biological Reviews, EarlyView.ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major
