Describing posterior distributions of variance components: Problems and the use of null distributions to aid interpretation
(Peer reviewed; Journal article, 2023)1. Assessing the biological relevance of variance components estimated using Markov chain Monte Carlo (MCMC)-based mixed-effects models is not straightforward. Variance estimates are constrained to be greater than zero and ... -
Moon phase and season alter road use by lions
(Peer reviewed; Journal article, 2023)Roads within protected areas facilitate management and tourism but can also alter animal movements and foraging opportunities. Animal tracks observed along roads are also used to index species distributions and abundance. ... -
A species-level trait dataset of bats in Europe and beyond
(Peer reviewed; Journal article, 2023)Knowledge of species’ functional traits is essential for understanding biodiversity patterns, predicting the impacts of global environmental changes, and assessing the efficiency of conservation measures. Bats are major ... -
Circular economy for aquatic food systems: insights from a multiscale phosphorus flow analysis in Norway
(Peer reviewed; Journal article, 2023)As wild-caught fish become scarce, feed ingredients for farming fish, such as salmon, are increasingly sourced from agricultural plants that depend on mineral fertilizers. Since these fish are naturally carnivorous, they ... -
Notes on Early Land Plants Today. 82. Frullanoides chinantlana (Gottsche) comb. nov., an older name for Frullanoides tristis (Steph.) van Slageren
(Peer reviewed; Journal article, 2023)Frullanoides tristis (Steph.) van Slageren is a well-established taxon and the name has been used frequently since the revision of the genus by van Slageren (1985). But there is a nomenclature problem with the name as van ... -

Upcycling of carbon, nitrogen, and phosphorus from aquaculture sludge using the polychaete Hediste diversicolor (OF Müller, 1776) (Annelida: Nereididae)
(Peer reviewed; Journal article, 2023)Introduction: Focusing on circular bioeconomy and finding solutions for managing finite and scarce resources such as phosphorus are issues that need to be addressed across sectors to attain food security. Land-based ... -
Adaptation to the High-Arctic island environment despite long-term reduced genetic variation in Svalbard reindeer
(Peer reviewed; Journal article, 2023)Typically much smaller in number than their mainland counterparts, island populations are ideal systems to investigate genetic threats to small populations. The Svalbard reindeer (Rangifer tarandus platyrhynchus) is an ... -
Evaluating permafrost definitions for global permafrost area estimates in CMIP6 climate models
(Peer reviewed; Journal article, 2023)Global permafrost regions are undergoing significant changes due to global warming, whose assessments often rely on permafrost extent estimates derived from climate model simulations. These assessments employ a range of ... -
The role of seasonality in shaping the interactions of honeybees with other taxa
(Peer reviewed; Journal article, 2023)The Eltonian niche of a species is defined as its set of interactions with other taxa. How this set varies with biotic, abiotic and human influences is a core question of modern ecology. In seasonal environments, the ... -
Effects of temperature, salinity and diet on embryonic and early larval development in Littorina littorea (Gastropoda: Littorinimorpha)
(Peer reviewed; Journal article, 2023)Introduction: The common periwinkle Littorina littorea is a delicacy in southern Europe. Enabling aquaculture production would be measure to avoid future over-harvesting and ensure a constant market supply. Methods: ... -
Immunomodulatory effect of different dietary ARA/EPA/DHA ratios in gilthead sea bream (Sparus aurata) juveniles after infection with Photobacterium damselae subsp. piscicida
(Peer reviewed; Journal article, 2022)The immunomodulatory effect of different dietary arachidonic acid (ARA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) ratios was evaluated in gilthead sea bream juveniles after intraperitoneal injection ... -
Adaptation to the High-Arctic island environment despite long-term reduced genetic variation in Svalbard reindeer
(Peer reviewed; Journal article, 2023)Typically much smaller in number than their mainland counterparts, island populations are ideal systems to investigate genetic threats to small populations. The Svalbard reindeer (Rangifer tarandus platyrhynchus) is an ... -
Mercury Exposure in Birds of Prey from Norway: Relation to Stable Carbon and Nitrogen Isotope Signatures in Body Feathers
(Peer reviewed; Journal article, 2023)Mercury (Hg) and stable carbon and nitrogen isotope ratios were analysed in body feathers from nestlings of white-tailed eagles (Haliaeetus albicilla) (WTE; n=13) and Northern goshawks (Accipiter gentilis) (NG; n=8) and ... -
Understanding Organisms Using Ecological Observatory Networks
(Peer reviewed; Journal article, 2023)Human activities are rapidly changing ecosystems around the world. These changes have widespread implications for the preservation of biodiversity, agricultural productivity, prevalence of zoonotic diseases, and sociopolitical ... -
A novel method for measuring acute thermal tolerance in fish embryos
(Peer reviewed; Journal article, 2023)Aquatic ectotherms are vulnerable to thermal stress, with embryos predicted to be more sensitive than juveniles and adults. When examining the vulnerability of species and life stages to warming, comparable methodology ... -
Eyes on the future: buffering increased costs of incubation by abandoning offspring
(Peer reviewed; Journal article, 2023)Life history theory states that the resources invested in current reproduction must be traded off against resources needed for survival and future reproduction. Long-lived organisms have a higher residual reproductive value ... -
Social and ecological drivers of illegal bird hunting in the Indawgyi wetland ecosystem in Myanmar
(Peer reviewed; Journal article, 2023)Hunting and illegal bird killing are major concerns for avian conservation globally. Unsustainable bird hunting in wetland habitats, particularly those located along important flyways, has contributed to avifauna defaunation ... -
Extreme events, trophic chain reactions, and shifts in phenotypic selection
(Peer reviewed; Journal article, 2023)Demographic consequences of rapid environmental change and extreme climatic events (ECEs) can cascade across trophic levels with evolutionary implications that have rarely been explored. Here, we show how an ECE in high ... -
