Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Aggregation of parasitism risk in an aphid-parasitoid system: Effects of plant patch size and aphid density

open access: yes, 2008
Few studies have linked density dependence of parasitism and the tritrophic environment within which a parasitoid forages. In the non-crop plant-aphid, Centaurea nigra-Uroleucon jaceae system, mixed patterns of density-dependent parasitism by the ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological 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.

In Situ Bilayer Interphase Enables Air‐Stable Li Metal Anode for Long‐Term Li‐Air Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An in situ formed bilayer SEI—featuring an Ag/LiF‐enriched inner backbone and a CF3‐dominated hydrophobic outer shell—enables fast/uniform Li+ transport and exceptional moisture‐air stability for Li metal. Lithium metal is an attractive anode for next‐generation high‐energy batteries, but its practical use is plagued by dendrite growth and parasitic ...

Intersexuality in the holotype of Photina gracilis (Mantodea: Mantidae: Photininae) and its taxonomic implications

open access: yesZoologia (Curitiba), 2014
Parasitism by horsehair worms (Nematomorpha) in Mantodea is well known, but only a few cases of intersexuality were reported in the literature. In the present study, intersexuality of the holotype of Photina gracilis Giglio-Tos, 1915 is documented as a ...

Environmental variability affects optimal trade‐offs in ecological immunology

open access: yesEcosphere, 2021
The costs of mounting and maintaining an immune response lead to trade‐offs with investment in (or maintenance of) other organ systems or functions such as reproduction, as has been observed in several taxa, including birds, insects, and mammals.

Host suitability of Mediterranean olive (Olea europaea L.) varieties to two root‐knot nematode species (Meloidogyne javanica and M. incognita) under greenhouse conditions

open access: yesNew Plant Protection, EarlyView.
Root‐knot nematodes significantly threaten olive production in Morocco. Screening of seven olive varieties revealed strong resistance in Koroneiki and Picholine Marocaine, characterized by suppressed nematode reproduction, sustained plant growth, and enhanced defense responses.

Rainforest conversion to monoculture plantations restructures functional communities of braconid parasitoid wasps

open access: yesOikos, EarlyView.
The conversion of rainforests into rubber and oil palm plantations drives biodiversity loss in Southeast Asia. Parasitoid wasps are highly diverse and play an essential role in ecosystems by regulating herbivore populations. Declines in density and diversity of parasitoid wasps, after land‐use change is well‐documented, but potential functional losses ...
