Toxicity and repellency of the monoterpenoids carvone and eucalyptol on Sitophilus zeamais: contact and fumigation-based interactionsNARA Subscribed
Corn is a globally important crop; however, pest infestations during storage represent a major challenge. The maize weevil, Sitophilus zeamais (Coleoptera: Curculionidae), is a primary pest of stored maize, commonly controlled through phosphine fumigation. Nevertheless, extensive reliance on this insecticide has led to the emergence of resistant populations. Thus, the objective of this study was to evaluate the contact and fum...
Timing of water limitation moderates drought hardiness traits of western larch (Larix occidentalis) seedlingsNARA Subscribed
Water limitation during tree seedling cultivation can promote traits that improve drought hardiness. Nurseries apply water limitation mostly during a brief developmental window of seedling growth, which may restrict the range of useful traits achievable through water limitation if phenotypic responses differ across ontogeny. We characterized the diversity of western larch ( Larix occidentalis (Nutt.)) seedling traits produced...
Bacteria are fundamental to coral health and resilience, though a dearth of knowledge exists on the formation of the coral microbiome in early life history stages. Although this initial microbial consortium is thought to hold key roles throughout development, its sparsity is easily obscured by environmental background microbiota. This opacity renders accurate studies of the early coral microbiome difficult, and limits applicat...
Coral larvae have unique transcriptomic responses to pathogenic and probiotic bacteriaNARA Subscribed
The growing prevalence of coral disease and other stressors threatens coral reefs, and evidence suggests these stressors not only affect adult corals but may also have impacts on early life stages. Yet, our understanding of coral larval physiology, including immunological function, is significantly limited. Here, we leverage the temperate coral experimental system Astrangia poculata to investigate the transcript-level response...
Species‐specific processing of fluorescent dissolved organic matter by Caribbean spongesNARA Subscribed
Coral reefs are biodiverse and productive ecosystems that are found in typically oligotrophic environments. Many studies have attempted to explain this paradox by demonstrating that microbial symbionts expand metabolic capabilities of host animals. However, few studies have determined if and how coexisting organisms and their symbiotic microbial communities partition available dissolved organic matter. To address this question...
A Coast-to-Coast Assessment of Cumulative Impacts and Protection Potential in Canadian Marine Conservation NetworksNARA Subscribed
The effectiveness of marine conservation networks depends on their ability to manage and safeguard against the many overlapping human activities and stressors influencing marine ecosystems. Cumulative impact mapping (CIM) combines information on the intensity and location of stressors with the spatial extent and vulnerability of marine habitats to generate a single, relative cumulative impact (CI) score. Despite its potential...
Diagnosing scaling bottlenecks in 10 community conservation initiatives in southern and eastern AfricaNARA Subscribed
Scaling area‐based conservation, including initiatives led or comanaged by Indigenous Peoples and local communities, is a flagship goal of the Kunming‐Montreal Global Biodiversity Framework. Conservationists often aspire to scale initiatives, but this is rarely achieved in practice. Identifying and addressing factors that limit initiative adoption (i.e., bottlenecks) could improve scaling strategies. We used insightsfrom 84 ex...
The archaeological site of Perdigões (Reguengos de Monsaraz, Portugal) was a centre of social and ceremonial importance with diverse funeral traditions from the middle 4th to the 3rd millennium BC. Previous strontium isotope analysis of human remains indicates that these funerary contexts contained individuals from a wide catchment area. Together with artefactual evidence, it suggests Perdigões was a part of a large interactio...
Primate populations worldwide are experiencing rapid declines due to habitat loss, degradation, and overexploitation. These pressures are particularly severe across sub-Saharan Africa and the Gulf of Guinea biodiversity hotspot, which supports several threatened and endemic species. The Ebo-Makombe-Ndokbou forests in southwestern Cameroon contain critical habitat for several of these species, including the Critically Endangere...
