Consequences of nest reuse for parasite burden and female health and condition in blue tits, Cyanistes caeruleus [PDF]

open access: yes, 2007
Research on the costs of nest reuse is central to understanding the population ecology and evolution of cavity-nesting birds. We explored the consequences of nest reuse by offering blue tits three types of nestboxes in which to breed: nestboxes with an ...

Developmental Stage‐Specific Responses to Extreme Climatic Events and Environmental Variability in Great Tit Nestlings

open access: yesGlobal Change Biology, Volume 32, Issue 3, March 2026.
Extreme climatic events (ECEs) impact great tit nestlings in a developmental stage‐specific and context‐dependent manner. Using 60 years of data on 83,000+ great tit nestlings from Wytham Woods, UK, we show that cold snaps are detrimental to hatchlings, while older nestlings are more affected by extreme rain and heat.

Predation vs. Parasitism: A Case Study of Indigenous Co‐Stewardship and Science Co‐Production to Measure Temporal Shifts in Moose Mortality on Ancestral Lands of the Grand Portage Ojibwe

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
This study, led by the Grand Portage Band of Lake Superior Chippewa, tracks survival and examines causes of adult moose mortality from 2010 to 2022 on the Grand Portage Indian Reservation and in Voyageurs National Park. Using a Bayesian framework, we integrated multiple contributing factors to accurately estimate cause‐specific mortality probabilities ...

Blood metabolites as predictors to evaluate the body condition of Neopelma pallescens (Passeriformes: Pipridae) in northeastern Brazil

open access: yesZoologia (Curitiba)
Body condition is an important ecological attribute that can provide a measure of the energy stored by an animal or population. Body condition is traditionally ascertained with morphometric body condition indices (BCIs), but some researchers have used ...

The little-known relationship between class insecta and rodents [PDF]

open access: yesArthropods, 2022
Rodents are one of the largest order of mammals and they are ubiquitous worldwide. Research has been done over the past years globally to understand the function and ecological role of rodents.

Temperature‐dependent interspecific interference alters pygmy backswimmer predation on water fleas

open access: yesEcological Entomology, Volume 50, Issue 5, Page 948-951, October 2025.
Increasing densities of water mites alter the predation behaviour of pygmy backswimmer, particularly in higher temperatures. Pygmy backswimmer displayed type II functional response across all the treatments. In the absence of water mites, the functional response was higher at 25°C than at 16°C, indicated by a higher space clearance rate.

Data from: Incongruence between morphological data sets: an example from the evolution of endoparasitism among parasitic wasps (Hymenoptera: Braconidae)

open access: yes, 1999
Phylogenetic analyses of molecular and morphological data sets for a group of parasitic wasps (Hymenoptera: Braconidae) give strikingly different results.

The marine leech Stibarobdella loricata (Harding, 1924) (Hirudinea, Piscicolidae), parasitic on the angel shark Squatina spp. and sandtiger shark Carcharias taurus Rafinesque, 1810 (Chondrichthyes: Squatinidae, Carchariidae) in Southern Brazilian waters

open access: yesBrazilian Journal of Biology, 2003
The presence of the marine leech, Stibarobdella loricata (Harding, 1924) (Hirudinea, Piscicolidae), is reported on the southern coast of Brazil, based on seven lots with 47 specimens, between 71 and 182 mm in total length, collected on the dorsal region ...

Superinfection Exclusion in Neotropical Honey Bees May Block DWV‐B, an Emerging Infectious Disease Variant of Deformed Wing Virus

open access: yesEvolutionary Applications, Volume 18, Issue 8, August 2025.
ABSTRACT RNA viruses often comprise multiple variants that co‐circulate in a host population, with potentially complex dynamics. Deformed wing virus (DWV), arguably the most impactful virus of honey bees (Apis mellifera), nowadays exists as two major variants, genotypes A (DWV‐A) and B (DWV‐B), which provide an amenable window into the dynamics of ...
