Introduction Picocyanobacteria from the genera Prochlorococcus and Synechococcus thrive across the globe in aquatic environments, have relatively small genomes, and have growth dynamics regulated by both viral interactions and abiotic conditions, making them excellent model organisms for exploring host-pathogencoevolution. Methods We developed and refined methods to sample and sequence cyanobacteria, cyanophages, and measured...
Values of protected area landscapes shape the behaviors of subsistence users in Interior AlaskaNARA Subscribed
Diverse values expressed by people living around protected areas provide insight into shared reasons why agreements and tensions may exist yet are underrepresented in research with subsistence users. We administered a mixed-mode survey to residents living near Denali National Park and Preserve and Denali State Park in Interior Alaska, USA, to understand how values placed on landscapes by multiple interest groups could lead to...
Species Loss Scenarios Identify Canada's Northern Ecosystems as Disproportionately VulnerableNARA Subscribed
Aim Amid ongoing and accelerating global change, predicting the ecological consequences of future species loss is important for prioritising conservation actions to protect biodiversity. Species richness has long been thought to protect communities from species loss by providing ecological redundancy, whereby the loss of any one species hardly impacts the integrity of the wider community due to overlap in species' ecological r...
Aim This study aims to understand how biological traits, human‐induced threats, and species popularity interact to influence the extinction risk of bird species globally. We seek to improve the accuracy of extinction risk assessments and inform conservation strategies. Location Global. Time Period Current. Major Taxa Studied Birds. Methods We predict extinction risk for bird species globally based on relevant biological traits...
Trophic Interactions Are Key to Understanding the Effects of Global Change on the Distribution and Functional Role of the Brown BearNARA Subscribed
Biotic interactions are expected to influence species' responses to global changes, but they are rarely considered across broad spatial extents. Abiotic factors are thought to operate at larger spatial scales, while biotic factors, such as species interactions, are considered more important at local scales within communities, in part because of the knowledge gap on species interactions at large spatial scales (i.e., the Eltoni...
Tempo and mode of diversification of the red devil spiders (Araneae: Dysderidae) of the Canary IslandsNARA Subscribed
The study of adaptive radiations has shed light on our current understanding of evolution. However, previous studies examining the mode in which species diversified, how diversification rates varied, and how ecological specialisation affected these processes have found few different results across different taxa and geographic and ecological systems, showing how complex this process is. To gain a more complete picture of how s...
Multi‐Species Telemetry Quantifies Current and Future Efficacy of a Remote Marine Protected AreaNARA Subscribed
Large‐scale marine protected areas (LSMPAs; > 1000 km 2 ) provide important refuge for large mobile species, but most do not encompass species' ranges. To better understand current and future LSMPA value, we concurrently tracked nine species (seabirds, cetaceans, pelagic fishes, manta rays, reef sharks) at Palmyra Atoll and Kingman Reef (PKMPA) in the U.S. Pacific Islands Heritage Marine National Monument. PKMPA and the U.S. E...
Avoidance and attraction responses of kittiwakes to three offshore wind farms in the North SeaNARA Subscribed
Seabird collision risk is a key concern in relation to the environmental impacts associated with offshore wind farms (OWFs). Understanding how species respond both to the wind farm itself, and individual turbines within the wind farm, is key to enabling better quantification and management of collision risk. Collision risk is of particular concern for the black-legged kittiwake, Rissa tridactyla , where modelling predicts unsu...
Trait‐matching models predict pairwise interactions across regions, not food web propertiesNARA Subscribed
Aim Food webs are essential for understanding how ecosystems function, but empirical data on the interactions that make up these ecological networks are lacking for most taxa in most ecosystems. Trait‐based models can fill these data gaps, but their ability to do so has not been widely tested. We test how well these models can extrapolate to new ecological communities both in terms of pairwise predator–prey interactions and hi...
Vertebrate species worldwide are currently facing significant declines in many populations. Although we have gained substantial knowledge about the direct threats that affect individual species, these threats only represent a fraction of the broader vertebrate threat profile, which is also shaped by species interactions. For example, threats faced by prey species can jeopardize the survival of their predators due to food resou...
Indicators to monitor the status of the tree of lifeNARA Subscribed
Following the failure to fully achieve any of the 20 Aichi biodiversity targets, the future of biodiversity rests in the balance. The Convention on Biological Diversity's Kunming–Montreal Global Biodiversity Framework (GBF) presents the opportunity to preserve nature's contributions to people (NCPs) for current and future generations by conserving biodiversity and averting extinctions. There is a need to safeguard the tree of...
