Parasites play a critical yet understudied role in Arctic ecosystems, particularly within key subsistence species such as Arctic char ( Salvelinus alpinus ). As the Arctic undergoes rapid climate-driven change, establishing baseline parasite biodiversity is essential for monitoring ecological shifts and anticipating emerging health and conservation concerns. This study provides the most comprehensive assessment to date of Arct...

In light of growing mental health challenges globally, understanding the positive impacts of nature on mental wellbeing is more important than ever. However, the impacts of one of the most common intentional human–wildlife interactions, feeding wild birds, are not well understood. We surveyed 3658 participatory scientists in the USA and Canada who take part in Project FeederWatch to examine associations between wellbeing and b...

Keymessage Standardized microhaplotype databases for eight diverse crops enable multiallelic analyses, comparative genetics, and breeding decisions. Abstract Microhaplotypes are short genomic segments that contain multiple tightly linked variants, providing multi-allelic data that can enhance genetic resolution compared to traditional biallelic single nucleotide polymorphism (SNP) markers. Here, we present the creation and uti...

Experimental determinations of trace element distribution between rocks/minerals and fluids at mantle pressures and temperatures have concentrated on eclogite and on fluids containing H 2 O with or without the addition of NaCl. Here we present data for websterite (pyroxenite) coexisting with five different fluids: H 2 O, H 2 O+CO 2 , H 2 O+NaCl, H 2 O+CO 2 +NaCl and H 2 O+NH 3 . All experiments were conducted at 1.5 GPa and 80...

Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high. Seabirds often segregate at sea according to sex and life‐history stage, and bycatch risk can vary accordingly. Few studies have tested whether spatial segregation among colonies...

Lynch syndrome, the most common hereditary cancer syndrome, is caused by germline pathogenic variants in DNA mismatch repair (MMR) genes. Identifying complex or structural MMR gene pathogenic variants can be challenging with short-read sequencing resulting in patients with unexplained MMR-deficient tumours. In this study, we report multiple members of a family who developed MSH2-deficient tumours where clinical multi-gene pane...

Rationale A major obstacle in the pre-clinical study of mood-related disorders and novel affective state therapeutic evaluation is the lack of animal models that fully recapitulate human symptomatology. Objective In this study, we developed a touchscreen-based cognitive judgement bias (CJB) task for mice. Methods In the CJB task, animals first learned to discriminate between two visual stimuli displayed on the touchscreen: one...

Victoria Cave, north Yorkshire, England, contains a long sequence of Pleistocene clastic sediments and calcite flowstones. Earlier work, using U–Th dating, established that the flowstone units formed in interglacial stages corresponding to Marine Isotope Stages (MIS) 13, 11, 9, 7 and 5. The intervening laminated sediments were therefore assigned to glacial stages (MIS 12, 10, 6 and 2) and regarded as rhythmites that settled fr...

Aim Evaluate the relative contributions of palaeotemperature, palaeogeographic reconfiguration, and habitat heterogeneity to the diversification and biogeographic history of turtles (Order Testudines) from the Triassic to the present. Location and Time Period Global; Triassic–Recent. Taxa Extant Testudines (time‐calibrated phylogeny sampling ~286 species). Methods We combined a near‐complete, time‐calibrated phylogeny with com...

Forests are vital for regulating climate and sustaining biodiversity, but climate change threatens their ability to do so, especially in the tropics. Our knowledge of how tropical forests and their constituent trees will respond to changes in climate is largely based on functional trait studies; however, few previous studies have investigated trait changes within individual tropical trees across decades, limiting our ability t...

Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now potentially becoming a global threat. Yet, no comprehensive appraisal exists across...

Indigenous tribal communities are frequently underserved by genomic medicine because they are under-represented in research, often live in remote locations and have ethical and cultural perspectives that vary from westernised standpoints. The Rakeiora platform, a permissioning and analytical environment that incorporates Māori perspectives and ethical frameworks on how precision medicine research is best conducted was used to...
