Brood parasitism by shiny cowbirds

, 2012
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 generalist parasite, the shiny cowbird (Molothrus bonariensis) and select hosts in Argentina.

Why rotation and mixture fail: treatment history and the declining acaricide efficacy in Varroa destructor

Pest Management Science, EarlyView.
The effect of IRM strategies (rotation, mixture), one additional year under acaricide treatment (Years treated (+1 year)), and one year without acaricide treatment (Years off treatment (+1 year) on mite mortality relative to an approximately 17% baseline.

Brown-and-yellow Marshbird (Pseudoleistes virescens) as a host of the Screaming Cowbird (Molothrus rufoaxillaris): first evidence of fledglings’ attendance

El Hornero
The Screaming Cowbird (Molothrus rufoaxillaris) is a highly specialized brood parasite that primarily parasitizes the Greyish Baywing (Agelaioides badius).

Comparison of nonchemical, organic and synthetic Varroa destructor control strategies in honey bee colonies: effects on parasite load, colony strength and health

Pest Management Science, EarlyView.
Combining intensive drone‐brood removal with brood interruption provided the most effective and consistent seasonal Varroa control. Abstract BACKGROUND Varroa destructor remains the most significant biotic threat to honey bee colonies, and increasing resistance to synthetic acaricides necessitates alternative control strategies.

Individual variation and prior experience affect the discrimination of a brood-parasite by its subsocial beetle host [PDF]

, 2018
In birds, host experience can modify response to parasites but nothing similar is known for insects. We studied two desert tenebrionid beetles, the subsocial host Parastizopus armaticeps and its obligate and ubiquitous brood-(clepto)parasite Eremostibes ...

A Multimodal In‐Situ Liquid Phase TEM and Electrochemical Study on Boric Acid as Electrolyte Additive for Alkaline Zinc‐Air Batteries

Small Methods, EarlyView.
This study establishes a multimodal correlative workflow to bridge disparate analytical scales in battery research. By linking dynamic in‐situ liquid‐phase TEM at the nanoscale with microscale morphological analysis and macroscale electrochemistry, a comprehensive mechanistic evaluation of electrolyte additives is achieved.

When will rejection of parasite nestlings by hosts of nonevicting avian brood parasites be favored? A misimprinting-equilibrium model

It has been suggested that discrimination and rejection of the nestlings of avian brood parasites are most likely to evolve when the parasite nestling is raised alongside the host nestlings, for example, many cowbird-host systems.

Avian brood parasitism and ectoparasite richness - scale-dependent diversity interactions in a three-level host-parasite system

, 2012
Brood parasitic birds, their foster species and their ectoparasites form a complex coevolving system composed of three hierarchical levels. However, effects of hosts’ brood parasitic life-style on the evolution of their louse (Phthiraptera: Amblycera ...
