Humpback Whale ( Megaptera novaeangliae ) Site Fidelity, Residency, and Movement Patterns in Ireland Based on Citizen Science DataNARA Subscribed
Understanding the residency and movement patterns of large cetaceans like the humpback whale is crucial for effective conservation. In Ireland, the Irish Whale and Dolphin Group has been collecting humpback whale data since the 1990s, primarily through citizen science. This collective effort has contributed to the creation of the Irish Humpback Whale Photo‐identification Catalogue. Using this dataset, we assessed humpback whal...
Assessment of two minimally invasive methodologies for sex identification in the European eel, Anguilla anguillaNARA Subscribed
Sex is an important driver of variation in behaviour, ecology and physiology. Sex identification in the Critically Endangered European eel ( Anguilla anguilla ) currently requires fish sacrifice, or the use of morphological differences such as body length, which can be inaccurate in certain habitats and at intermediate body lengths. Non‐lethal tools for accurate sex identification in this species are therefore required. Here,...

Intervertebral disc degeneration is accelerated by GH overexpression but attenuated by GH antagonismNARA Subscribed
Background Intervertebral disc degeneration (IVDD) is a leading contributor to lower back pain, yet its underlying mechanisms remain poorly defined. While insulin-like growth factor 1 (IGF-1) has been implicated in disc homeostasis, the specific contributions of growth hormone (GH)—a key upstream regulator of IGF-1 that also acts and independently influences skeletal tissues—have not been thoroughly investigated in the context...
Animal morphometrics are essential for understanding a species’ life history and its ecological interactions with the environment. This study investigates the maturity status and body condition of humpback whales ( Megaptera novaeangliae ) across understudied areas of the Northeastern Atlantic Ocean. Uncrewed Aerial Systems (UAS or drones) were used to collect photogrammetry data from humpback whales in Ireland, Norway, and Ca...
Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Postglacial Recolonization of the Southern Ocean by Elephant Seals Occurred From Multiple Glacial RefugiaNARA Subscribed
The Southern Ocean is warming more rapidly than other parts of our planet. How this region's endemic biodiversity will respond to such changes can be illuminated by studying past events through genetic analyses of time‐series data sets, including historic and fossil remains. Archaeological and subfossil remains show that the southern elephant seal ( Mirounga leonina ) was common along the coasts of Australia and New Zealand in...
Entomopathogenic Nematode Species Vary in Their Behavior and Virulence in Response to Cardiac Glycosides Within and Around Insect HostsNARA Subscribed
Plants produce defensive toxins to deter herbivores. In response, some specialized herbivores evolved resistance and even the capacity to sequester toxins, affecting interactions at higher trophic levels. Here, we test the hypothesis that potential natural enemies of specialized herbivores are differentially affected by plant toxins depending on their level of adaptation to the plant-herbivore system. We focus on toxic cardiac...
Motivation Pollinators play a crucial role in maintaining Earth's terrestrial biodiversity. However, rapid human‐induced environmental changes are compromising the long‐term persistence of plant‐pollinator interactions. Unfortunately, we lack robust, generalisable data capturing how plant‐pollinator communities are structured across space and time. Here, we present the EuPPollNet (European Plant‐Pollinator Networks) database,...
The Toxicology Investigators Consortium 2023 Annual ReportNARA Subscribed
Language matters in shaping perceptions and guiding behaviour. The term stakeholder is widely used, yet little attention is paid to the possibility that its use may inadvertently perpetuate colonial narratives and reinforce systemic inequities. In this article, we critically examine the limitations of the stakeholder concept and its ambiguity, normativity, and exclusionary implications. We emphasise the importance of using lan...
The Toxicology Investigators Consortium 2022 Annual ReportNARA Subscribed
Human‐mediated changes in island vegetation are, among others, largely caused by the introduction and establishment of non‐native species. However, data on past changes in non‐native plant species abundance that predate historical documentation and censuses are scarce. Islands are among the few places where we can track human arrival in natural systems allowing us to reveal changes in vegetation dynamics with the arrival of no...
Association patterns and community structure among female bottlenose dolphins: environmental, genetic and cultural factorsNARA Subscribed
Social structuring from assortative associations may affect individual fitness, as well as population-level processes. Gaining a broader understanding of social structure can improve our knowledge of social evolution and inform wildlife conservation. We investigated association patterns and community structure of female Indo-Pacific bottlenose dolphins ( Tursiops aduncus ) in Shark Bay, Western Australia, assessing the role of...
