Rare insights into intraspecific brood parasitism and apparent quasi–parasitism in black–capped chickadees

open access: yesAnimal Biodiversity and Conservation, 2011
Genetic analysis of passerine birds often finds evidence of extra–pair copulations within species, but genetic evidence of intraspecific brood parasitism (IBP) and quasi–parasitism (Q–P) are relatively rare. Further, it is even rarer for genetic patterns

Natural parasitism of the Citrus Leafminer (Lepidoptera: Gracillariidae) over eight years in seven citrus regions of São Paulo, Brazil [PDF]

open access: yes, 2015
The citrus leafminer (CLM) Phyllocnists citrella Stainton (Lepidoptera: Gracillariidae) was frst recorded in Brazil in 1996. In 1998, the parasitoid Ageniaspis citricola Logvinovskaya (Hymenoptera: Encyrtdae) was introduced and established in many ...

Parasite infection and the movement of the aquatic snail Potamopyrgus antipodarum along a depth cline

open access: yesEcology and Evolution, 2023
Parasite species that use two or more host species during their life cycle depend on successful transmission between these species. These successive host species may have different habitat requirements.

A game-theoretic model of interspecific brood parasitism with sequential decisions [PDF]

open access: yes, 2008
The interaction between hosts and parasites in bird populations has been studied extensively. This paper uses game-theoretic methods to model this interaction.

Hijacking the Host Clock: A Nematode Effector Antagonizes Soybean Circadian Defense and Translation Control

open access: yesAdvanced Science, EarlyView.
Soybean employs its circadian clock, governed by GmCCA1, to rhythmically defend against soybean cyst nematodes. The pathogen retaliates by secreting the effector Hg4E02, which hijacks the clock to suppress defense and co‐opt the host's translation machinery for nutrient acquisition.

Effect on Constant Versus Fluctuating Temperature Regimes on \u3ci\u3eBathyplectes Curculionis\u3c/i\u3e (Hymenoptera: Ichneumonidae) Activity [PDF]

open access: yes, 2017
Individual female Bathyplectes curculionis parasites were exposed to either a series of constant or fluctuating temperature regimes and supplied with a new group of host Hypera postica larvae every day.

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

open access: yesAdvanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Trophic Diversity in Duckweed: Mixotrophy, More Than the Sum of its Extremes

open access: yesAdvanced Science, EarlyView.
In the context of rising DOC in aquatic environments, mixotrophic duckweed may impact carbon cycling by acting as either a carbon sink, as they absorb CO2 through photosynthesis, or a carbon source, as they release CO2 through respiration of absorbed DOC, which depends on DOC concentration, light availability, temperature, and other environmental ...

Sex‐ and state‐dependent covariation of risk‐averse and escape behavior in a widespread lizard

open access: yesEcology and Evolution, 2023
Mounting evidence has shown that personality and behavioral syndromes have a substantial influence on interspecific interactions and individual fitness.

Equine models in translational medicine: A comparative approach to human health

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This diagram summarizes and contrasts rodent and equine models, outlining their strengths, limitations, and applications. Horses offer naturally occurring diseases, genetic and physiological similarities to humans, and suitability for longitudinal and clinical‐scale studies.
