Predictors and consequences of diet composition in a declining generalist aerial insectivoreNARA Subscribed
For generalist animals that have a broad range of food choices, the specific diet characteristics that are important for health and fitness are often unclear. Here, we examine whether individual variation in diet composition predicts nestling mass and fledge success, and we identify potential drivers of variation in diet composition, in a declining generalist aerial insectivore, the tree swallow ( Tachycineta bicolor ). We col...

The impact of coal mine dust characteristics on pathways to respiratory harm: investigating the pneumoconiotic potency of coalsNARA Subscribed
Exposure to dust from the mining environment has historically resulted in epidemic levels of mortality and morbidity from pneumoconiotic diseases such as silicosis, coal workers’ pneumoconiosis (CWP), and asbestosis. Studies have shown that CWP remains a critical issue at collieries across the globe, with some countries facing resurgent patterns of the disease and additional pathologies from long-term exposure. Compliance meas...
Marine natural sciences have been instrumental in helping society understand how ocean systems operate and the threats they face. However, there is a growing realisation that the societal challenges related to the marine environment can only be addressed through more effective integration with all aspects of social sciences. Nevertheless, to date, social sciences remain insufficiently integrated into marine research. Recognisi...
In an investigation of stromatic Xylariales in Thailand, several specimens of Daldinia were discovered. Three novel species ( D. flavogranulata , D. phadaengensis , and D. chiangdaoensis ) were recognized from a molecular phylogeny based on concatenated ITS, LSU, RPB2 , and TUB2 sequence data, combined with morphological characters and secondary metabolite profiles based on high performance liquid chromatography coupled to dio...
Birds are hosts for several zoonotic pathogens. Because of their high mobility, especially of longdistance migrants, birds can disperse these pathogens, affecting their distribution and phylogeography. We focused on Borrelia burgdorferi sensu lato, which includes the causative agents of Lyme borreliosis, as an example for tick‐borne pathogens, to address the role of birds as propagation hosts of zoonotic agents at a large geog...
Economically viable aquaponics? Identifying the gap between potential and current uncertaintiesNARA Subscribed
Aquaponics, which integrates hydroponic farming and aquaculture, has the potential for sustainably producing high‐quality food, but has yet to achieve commercial success. In recent years, however, commercial‐scale aquaponics has received considerable attention from the scientific community, with the current literature covering many aspects of aquaponic production. We reviewed this literature and classified the specific areas c...
The current extinction and climate change crises pressure us to predict population dynamics with ever‐greater accuracy. Although predictions rest on the well‐advanced theory of age‐structured populations, two key issues remain poorly explored. Specifically, how the age‐dependency in demographic rates and the year‐to‐year interactions between survival and fecundity affect stochastic population growth rates. We use inference, si...

Global importance of large‐diameter treesNARA Subscribed
Aim To examine the contribution of large‐diameter trees to biomass, stand structure, and species richness across forest biomes. Location Global. Time period Early 21st century. Major taxa studied Woody plants. Methods We examined the contribution of large trees to forest density, richness and biomass using a global network of 48 large (from 2 to 60 ha) forest plots representing 5,601,473 stems across 9,298 species and 210 plan...
