Trade‐offs in avian parental care: a review of theory and meta‐analysis of brood size manipulations
Biological Reviews, EarlyView.ABSTRACT The selective forces shaping parental care have been studied for over 50 years. While theoretical and experimental work has yielded qualitative progress, the large body of empirical work testing predictions about parental investment based on life‐history trade‐offs has yet to be synthesized.

A Problem in the Flight of Insects
Annals of the Entomological Society of America, 1912 In the usual explanations for the flight of insects, the mechanism is considered essentially as a plane with a rigid anterior border, flexible hinder border and with a vertical movement so that the vibrations result in the forward propulsion of the insect and, so far as I am aware, no further discussion of the modes of progression have been presented ...

Orchard netting impacts on biodiversity leading to cascading effects at the ecosystem level
Biological Reviews, EarlyView.ABSTRACT Agriculture must ensure food production without further compromising the ecosystem functions upon which it depends. Agricultural practices should therefore avoid harming farmland biodiversity, especially of taxa that supply the key ecosystem services (e.g.

What drives animal responses to high severity fire? The role of functional traits
Biological Reviews, EarlyView.ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

, 2020 Insects are flying all around us. However, answering the question: How do insects fly? is difficult. In this thesis, we set out to uncover the relation between the movement of the wing of an insect and the aerodynamic forces. For this we used two Dipteran species as model organisms for low frequency high amplitude and high frequency low amplitude ...

Animal empathy reconsidered: a multidimensional profile account
Biological Reviews, EarlyView.ABSTRACT Empathy is the glue that holds societies together and yet several fundamental questions about empathy persist. What is empathy (the definitional question)? Is it uniquely human and, if not, which nonhuman animals possess empathy (the distribution question)? Which type or quality of empathy is realized in different species (the quality question)

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives
Biological Reviews, EarlyView.ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.
