Mature cow weight (MWT), height (MHT), and body condition score (BCS) are economically important traits that significantly influence cowherd profitability by affecting maintenance feed requirements, which is the largest component of production costs. This study aimed to identify genomic regions, candidate genes, and pleiotropic variants associated with mature cow size traits in American Angus cattle, and to characterize their...
Benthic primary producers affect pelagic nitrogen fixation by influencing benthic nutrient fluxes in a shallow lakeNARA Subscribed
Nutrient supply is an important determinant of N fixation rates in pelagic cyanobacteria. In shallow aquatic ecosystems, benthic primary producers can affect nutrient release from the sediment to the pelagic zone, yet the relationship between benthic primary producers and pelagic N fixation is not well understood. Here, we explore the effect of benthic primary producers on benthic nutrient fluxes and pelagic N fixation rates i...
Individual Trees Respond to 40 Years of Climate Change Through Leaf Functional Trait AcclimationNARA Subscribed
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...
Insights from three decades of IUCN Red List assessments catalyzing shark, ray, and chimaera conservationNARA Subscribed
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is a critical measure of global aquatic and terrestrial biodiversity status. It is also the basis for the Red List Index, which tracks extinction risk over time. Sharks, rays, and chimaeras (Chondrichthyes) have now been comprehensively assessed twice (1996–2011 and 2012–2021) with hindcast assessments from 1970 onward, yielding an unprece...
Ecosystem engineering by primary consumers increases long-term benthic primary production in Lake Mývatn, IcelandNARA Subscribed
Ecosystem engineers impact ecosystems by changing the physical environment in which species interact. In Lake Mývatn, Iceland, larvae of the midge Tanytarsus gracilentus function as ecosystem engineers by building tubes in the sediment that solidify the benthic surface and create a 3-dimensional structure on which microalgae can grow. To assess the ecosystem-scale effect of midge engineering, we took advantage of the natural h...
Organisms that move across ecosystem boundaries can create resource gradients in adjacent ecosystems. Midges that emerge from Lake Mývatn, Iceland, are deposited as nutrient-rich carcasses on land, and this generates a nutrient gradient from its shoreline. We contrasted the distribution and photobiont characteristics of two lichen species, Nephromopsis cucullata and Peltigera leucophlebia, in a lava field adjacent to Mývatn al...
Inorganic nutrients can vary over space and time in lakes due to abiotic and biotic factors. To understand the drivers of spatial variation in nutrients in shallow Lake Mývatn, Iceland, we mapped dissolved inorganic and organic nitrogen (N) and phosphorus (P) concentrations in benthic (interstitial) and pelagic zones in summer 2021 during a lake-wide pelagic cyanobacterial bloom and in spring 2022 when there was no cyanobacter...
Dynamics and drivers of benthic crustaceans in Lake MývatnNARA Subscribed
The community of benthic crustaceans in Lake Mývatn, Iceland, is dynamic, with different taxa showing different patterns of variation through time. Here, we analyze the dynamics of eight crustaceans collected during the summer from a central station in Mývatn over 29 years, 1995–2023. We investigated the hypothesis that fluctuations in the dominant benthic tube-forming midge, Tanytarsus gracilentus , drives fluctuations in ben...
In nitrogen-limited lakes, cyanobacterial nitrogen (N) fixation rates can be high. However, the effect of cyanobacterial N fixation on ecosystem N availability depends, in part, on the retention of fixed N. Here, we explore patterns of benthic and pelagic N fixation and fixed N retention in Lake Mývatn, Iceland. Our N budget, updated from previous assessments, showed that the annual rate of lake-scale N fixation needed to acco...
Balancing risk and reward: Toward resilient human–primate coexistence in a rapidly changing environment in Sulawesi, IndonesiaNARA Subscribed
This study explores human–moor macaque ( Macaca maura ) coexistence in Sulawesi, Indonesia, using resilience thinking to assess temporal patterns of coadaptation amidst stressors such as provisioning and road construction. Comparing data from 2016–2017 to 2023–2025, we examine changes in provisioning patterns, macaque roadside use, and people’s perceptions of macaques to evaluate factors that may test the system’s resilience....
Fine‐Scale Ecological Biomonitoring in a Large, Complex Agriculturally Impacted Watershed via eDNA MetabarcodingNARA Subscribed
DNA‐based approaches utilizing high‐throughput sequencing (HTS) (e.g., DNA metabarcoding) have revolutionized ecological biomonitoring by providing higher sample throughput, greater reproducibility, and better cost‐benefits compared to traditional morphology‐based bioassessment studies. Here, we utilized DNA metabarcoding in a watershed in Ontario (Canada) dominated by agricultural land uses. Our aim is to understand patterns...
A Review of Advances in Nutrition Research towards Commercial Aquaculture of Pompanos, Trachinotus spp.NARA Subscribed
Among the jack family (Carangidae), pompanos, Trachinotus spp., are the most farmed globally. The top four most aquacultured species are golden pompano, T. ovatus , snubnose pompano, T. blochii , Indian pompano, T. mookalee , and Florida pompano, T. carolinus . While initial efforts to culture these species heavily relied on wild‐caught small fish of various species (commonly referred to as ‘trash fish’) for growout, pompanos...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Seed production on native seed farms has increased to meet the rising demand for plant material for restoration. Although these propagation efforts are necessary for restoration, cultivating wild populations may also result in unintentional selection and elicit evolutionary changes that mimic crop domestication, essentially turning these efforts into artificial domestication experiments. Here, we investigated whether phenotypi...
