Exploring Science Identity and Latent Factors of Student Gains in a Place-based Marine Science CURE Designed to Provide Access to Hawai'i Students from Historically Marginalized Ethnicities.

Hawai'i students, and in particular Native Hawaiian students, face high rates of attrition and low representation in Science, Technology, Engineering, and Mathematics (STEM) academic majors and careers, but place-based Course-based Undergraduate Research Experiences (CUREs) such as the Research Experiences in Marine Science (REMS) summer program may help to better engage these students with scientific content understanding and skills development. This article assesses latent factors of student gains after participating in the REMS program as they relate to student science identity. Results from an exploratory factor analysis examining the internal structure of an assessment measure delivered during the program suggest strong evidence of four latent factors in student self-reported learning gains: Content Understanding, Scientific Skills, Interest, and Integration.

Study Protocol: Interactive Dynamics of Coral Reef Fisheries and the Nutrition Transition in Kiribati.

The Kiribati 2019 Integrated Household Income and Expenditure Survey (Integrated HIES) embeds novel ecological and human health research into an ongoing social and economic survey infrastructure implemented by the Pacific Community in partnership with national governments. This study seeks to describe the health status of a large, nationally representative sample of a geographically and socially diverse I-Kiribati population through multiple clinical measurements and detailed socio-economic surveys, while also conducting supporting food systems research on ecological, social, and institutional drivers of change. The specific hypotheses within this research relate to access to seafood and the potential nutritional and health benefits of these foods.

Environmental performance of blue foods.

Fish and other aquatic foods (blue foods) present an opportunity for more sustainable diets. Yet comprehensive comparison has been limited due to sparse inclusion of blue foods in environmental impact studies relative to the vast diversity of production. Here we provide standardized estimates of greenhouse gas, nitrogen, phosphorus, freshwater and land stressors for species groups covering nearly three quarters of global production.

Depth as an organizing force in Pocillopora damicornis: intra-reef genetic architecture.

Relative to terrestrial plants, and despite similarities in life history characteristics, the potential for corals to exhibit intra-reef local adaptation in the form of genetic differentiation along an environmental gradient has received little attention. The potential for natural selection to act on such small scales is likely increased by the ability of coral larval dispersal and settlement to be influenced by environmental cues. Here, we combine genetic, spatial, and environmental data for a single patch reef in Kāne'ohe Bay, O'ahu, Hawai'i, USA in a landscape genetics framework to uncover environmental drivers of intra-reef genetic structuring.

Rise and fall of a hybrid zone: implications for the roles of aggression, mate choice, and secondary succession.

Hybridization can be an important evolutionary force by generating new species and influencing evolution of parental species in multiple ways, including introgression and the consequences of hybrid vigor. Determining the ecological processes underlying evolution in hybrid zones is difficult however because it requires examining changes in both genotypic frequencies over time and corresponding ecological information, data that are rarely collected together. Here, we describe genetic and ecological aspects of a hybrid zone between the Eastern Fence Lizard, Sceloporus undulatus, and the Florida Scrub Lizard, Sceloporus woodi, occurring over at least 23 generations.

Genetic relatedness does not retain spatial pattern across multiple spatial scales: dispersal and colonization in the coral, Pocillopora damicornis.

Patterns of isolation by distance are uncommon in coral populations. Here, we depart from historical trends of large-scale, geographical genetic analyses by scaling down to a single patch reef in Kāne'ohe Bay, Hawai'i, USA, and map and genotype all colonies of the coral, Pocillopora damicornis. Six polymorphic microsatellite loci were used to assess population genetic and clonal structure and to calculate individual colony pairwise relatedness values.
