Habitat associations and nest survival of Yellow Warblers in California [PDF]
Yellow Warblers have experienced population declines in California, earning them special status as a Species of Special Concern. The causes are thought to be habitat loss, nest predation, and Brown-headed Cowbird parasitism.

Twenty‐four bark beetle biocontrol programmes involving 41 natural enemy introductions are reported globally. A total of 36.6% of agents were established and 9.8% were reported effective, while many agent establishments and impacts often remained unassessed and incomparable across regions.

Brood parasitism by shiny cowbirds
Brood parasitic birds lay eggs amongst the clutches of other species, which then assume all costs of parental care on their behalf. This thesis addresses several puzzles of avian brood parasitism, using field studies and theoretical modelling of the ...

THE NEST AND EGGS OF BLACK-CAPPED SPARROW Arremon a. abeillei (PASSERELLIDAE) IN SOUTHWESTERN ECUADOR [PDF]
I describe the nest and egg of Black-capped Sparrow (Arremon a. abeillei), providing the first substantiated information on its reproductive biology and the first report of brood parasitism by Shiny Cowbird (Molothrus bonariensis).

ABSTRACT One core aspect of science is communication, both among researchers as well as with the public. For successful communication, it is crucial that the terminology used is clear to avoid misunderstandings. Especially when researchers working on different groups of organisms communicate, they often use different terms for similar morphological ...

Larval character evolution in Holometabola (Insecta)
Abstract Larvae, a novel type of immature stage, are a crucial innovation of the Holometabola. Larval features therefore provide key evidence for reconstructing evolutionary transformations in this megadiverse group. Here we present the first formal reconstruction of larval character evolution, using maximum parsimony and Bayesian ancestral‐state ...

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

Several hypotheses have been proposed to explain the evolution of conspecific brood parasitism (CBP), and recent studies suggest that nest predation may be an important factor in shaping this behavior.

We describe methods for collecting and rearing the tachinid parasitoid Istocheta aldrichi from parasitized Japanese beetle adults. Hosts can be collected by hand and reared in the laboratory, or by using modified trap containers with added plant material and substrate to provide suitable conditions for I.

Larval parasitism of the autumnal moth reduces feeding intensity on the mountain birch [PDF]
Plants respond to grazing by herbivorous insects by emitting a range of volatile organic compounds, which attract parasitoids to their insect hosts. However, a positive outcome for the host plant is a necessary precondition for making the attraction ...
