The sight of an adult brood parasite near the nest is an insufficient cue for a honeyguide host to reject foreign eggs. [PDF]

open access: yes, 2015
Hosts of brood-parasitic birds typically evolve anti-parasitism defences, including mobbing of parasitic intruders at the nest and the ability to recognize and reject foreign eggs from their clutches.

Heteronanoarchitecture of Ti3C2Tx MXene and Amorphous MOF for Exceptional Durability in Electro‐Ionic Soft Actuator

open access: yesAdvanced Materials, EarlyView.
The nanoscale hybridization of MXene and amorphous metal‐organic framework (MXene–aMOF) achieves exceptional electrochemical stability and ion storage capacity, attributed to the synergistic interplay between the nanoporous surfaces of aMOF and the metal‐like electron conduction of MXene.

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

Susceptibility of rubber trees to Loranthaceae in Gabon [PDF]

open access: yes, 2009
In Gabon, two major species of Loranthaceae, Phragmanthera capitata (Sprengel) Balle and Globimetula braunii (Engl.) Danser to a lesser extent, parasitize Hevea brasiliensis (Muumlll.) Arg.

Role of the Setae in an Ectoparasitic Seal Louse in Reducing Surface Drag: Numerical Modeling Approach

open access: yesAdvanced Theory and Simulations, EarlyView.
The seal louse Echinophthirius horridus has uniquely shaped setae that may reduce drag during its host's dives. Using numerical simulations, this study demonstrates that their natural inclination promotes vortex formation, minimizing friction and energy loss. These findings provide insights into biological surface adaptations and may inspire the design

Plants, plant‐derived compounds, probiotics, and postbiotics as green agents to fight against poultry coccidiosis: A review

open access: yesAnimal Research and One Health, EarlyView.
Therapeutic effect of natural products on chicken coccidiosis. Abstract The intestinal tract is the main place for animals to digest food and absorb nutrients, which also serves as the first line of defense against pathogens that invade the internal environment.

Eastern Pine Seedworm, \u3ci\u3eCydia Toreuta\u3c/i\u3e (Lepidoptera: Tortricidae) in Red Pine Cones in Wisconsin [PDF]

open access: yes, 2017
Cydia toreuta population densities, prolonged diapause behavior, parasitism and adult emergence patterns were examined over four years at two red pine locations in Wisconsin. Last-instar densities ranged from 0.54 to 3.18 per cone.

Analyzing the Mass-Rearing System of the California Red Scale Parasitoid Aphytis melinus (Hymenoptera: Aphelinidae) [PDF]

open access: yes, 2018
Results from studies to improve mass rearing production of the parasitoid Aphytis melinus De Bach (Hymenoptera: Aphelinidae) are presented. Parasitoid production was carried out following standard commercial procedures using an alternative host ...

Daphnia‐associated bacterial communities correlate with diet quantity, environmental conditions, and epidemic size across natural outbreaks

open access: yesLimnology and Oceanography, EarlyView.
Abstract Zooplankton‐associated microbiomes play an important role for host health, and contribute to ecosystem processes such as nutrient cycling. Yet, few studies have assessed how environmental gradients and biotic interactions, including parasitism and diet, may shape the microbiome composition of wild zooplankton. Here, we analyzed the microbiomes
