Drivers of brood parasitism in solitary bees across a South American dryland ecoregion

open access: yes
International audienceAbstractWild bees are parasitized by a variety of organisms, including those that attack brood cells within nests. Brood parasitism reduces reproductive output by increasing offspring mortality, with potential impacts on the ...

Adaptation to extreme environments: A review of Antarctic fish physiology

open access: yesJournal of Fish Biology, EarlyView.
Abstract Having evolved in the chronically cold and thermally stable waters of the Southern Ocean (SO) for millions of years, Antarctic fish possess a suite of physiological specializations that enable them to survive at temperatures near the freezing point of seawater. Adaptations include the evolution of antifreeze proteins, modifications of membrane

Comparative Loss of Reproductive Potential Among Increased Clutch Sizes in Relation to Climate Change in a High Trophic Avian Predator: A 44‐Year Study

open access: yesJournal of Zoology, EarlyView.
A North America, Wisconsin population of breeding Cooper's Hawks (Astur cooperii) is responding favorably to recent climate change with earlier egg‐laying and increased reproduction. But a 44‐year study demonstrated that tallies of older age offspring only at the nestling stage wouldunderestimate the comparatively higher loss of embryos and hatchlings ...

Experimental shifts in intraclutch egg color variation do not affect egg rejection in a host of a non-egg-mimetic avian brood parasite.

open access: yesPLoS ONE, 2015
Avian brood parasites lay their eggs in the nests of other birds, and impose the costs associated with rearing parasitic young onto these hosts. Many hosts of brood parasites defend against parasitism by removing foreign eggs from the nest.

Narrator, character, other: Kafka’s triangle in Fürsprecher

open access: yesOrbis Litterarum, EarlyView.
Abstract Franz Kafka's protagonists are conspicuously featureless, and yet Kafka is persistently read as a fabulist of the plight of the individual before impervious, impersonal, and indifferent legal structures. How can Kafka champion the individual against such forces when his heroes do not have personalities to lose?

Reticence or vigilance at the nest: a cruel bind for the endangered Black-capped Vireo

open access: yesAvian Conservation and Ecology, 2017
Breeding birds vocalize to find mates and establish and defend territories, but these same critical communications may also attract predators or brood parasites, placing birds in a cruel bind.

Nest design as an adaptative tool to escape brood parasitism

open access: yes, 2023
1. Nest characteristics vary depending on environmental factors but may also be influenced by between-species interactions. As a defence against avian brood parasites, hosts can evolve specific nest architecture to minimise risks of brood parasitism by ...

Rhizobacterial Modulation of Maize Defense Alters Herbivore Performance and Parasitoid Behavior

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT The association between plants and beneficial soil microorganisms can profoundly influence aboveground trophic interactions, yet these effects are often context‐dependent. Although plant growth‐promoting rhizobacteria (PGPR) are increasingly used in maize production, little is known about how these microorganisms affect maize defenses against ...

Supplementary methods and figures from Host density predicts the probability of parasitism by avian brood parasites

open access: yes, 2019
The spatial distribution of hosts can be a determining factor in the reproductive success of parasites. Highly aggregated hosts may offer more opportunities for reproduction but can have better defences than isolated hosts.
