The evolution of gregariousness in parasitoid wasps [PDF]

open access: yes, 1998
Data are assembled on the clutch-size strategies adopted by extant species of parasitoid wasp. These data are used to reconstruct the history of clutch-size evolution in the group using a series of plausible evolutionary assumptions.

Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Quantitative synthesis of the effects of drought on community composition and species interactions in terrestrial ecosystems

open access: yesOikos, EarlyView.
Droughts, increasingly frequent under human‐driven climate change, are expected to intensify globally. Both pulsed and prolonged droughts can strongly affect organismal survival and population dynamics, potentially altering terrestrial communities and ecosystems.

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.
