The contribution of aquatic foods to human nutrient intake and adequacy in a small Island developing state.

Many Small Island Developing States (SIDS) are experiencing a nutrition transition, wherein high prevalence of malnutrition co-occurs with growing rates of diet-related non-communicable diseases. Sustainably managed and accessible aquatic foods can serve as a rich and bioavailable source of nutrients, helping communities achieve healthy diets and meet key sustainable development goals (e.g.

Prevalence and spatio-demographic variability of nutrition-related health issues in Kiribati.

The nutrition transition in Small Island Developing States like Kiribati has led to a significant shift from traditional diets to processed, imported foods, resulting in a double burden of malnutrition. This study provides the first comprehensive assessment of nutrition-related health issues in Kiribati, analyzing data from a nationally representative household survey conducted in 2019-2020 (with over 12,000 participants). We examined anthropometric measures and biomarkers related to both under- and overnutrition across 21 islands, including obesity, anemia, hypertension, diabetes, and dyslipidemia.

Characterizing pathways of seafood access in small island developing states.

Ensuring healthy and sustainable food systems in increasing social, economic, and ecological change is a key global priority to protect human and environmental health. Seafood is an essential component of these food systems and a critical source of nutrients, especially in coastal communities. However, despite rapid transformations in aquatic food systems, and our urgent need to understand them, there is a dearth of data connecting harvested food production to actualized food consumption.

Effects of management objectives and rules on marine conservation outcomes.

Understanding the relative effectiveness and enabling conditions of different area-based management tools is essential for supporting efforts that achieve positive biodiversity outcomes as area-based conservation coverage increases to meet newly set international targets. We used data from a coastal social-ecological monitoring program in 6 Indo-Pacific countries to analyze whether social, ecological, and economic objectives and specific management rules (temporal closures, fishing gear-specific, species-specific restrictions) were associated with coral reef fish biomass above sustainable yield levels across different types of area-based management tools (i.e.

Inter-group alliance dynamics in Indo-Pacific bottlenose dolphins (Tursiops aduncus).

The social intelligence hypothesis holds that complex social relationships are the major selective force underlying the evolution of large brain size and intelligence. Complex social relationships are exemplified by coalitions and alliances that are mediated by affiliative behavior, resulting in differentiated but shifting relationships. Male Indo-Pacific bottlenose dolphins in Shark Bay, Australia, form three alliance levels or 'orders', primarily among non-relatives.

Allied male dolphins use vocal exchanges to "bond at a distance".

Vocal interactions are intrinsic features of social groups and can play a pivotal role in social bonding. Dunbar's social bonding hypothesis posits that vocal exchanges evolved to "groom at a distance" when social groups became too large or complex for individuals to devote time to physical bonding activities. Tests of this hypothesis in non-human primates, however, suggest that vocal exchanges occur between more strongly bonded individuals that engage in higher grooming rates and thus do not provide evidence for replacement of physical bonding.

Affiliation history and age similarity predict alliance formation in adult male bottlenose dolphins.

Male alliances are an intriguing phenomenon in the context of reproduction since, in most taxa, males compete over an indivisible resource, female fertilization. Adult male bottlenose dolphins () in Shark Bay, Western Australia, form long-term, multilevel alliances to sequester estrus females. These alliances are therefore critical to male reproductive success.

Bottlenose Dolphins Retain Individual Vocal Labels in Multi-level Alliances.

Cooperation between allied individuals and groups is ubiquitous in human societies, and vocal communication is known to play a key role in facilitating such complex human behaviors [1, 2]. In fact, complex communication may be a feature of the kind of social cognition required for the formation of social alliances, facilitating both partner choice and the execution of coordinated behaviors [3]. As such, a compelling avenue for investigation is what role flexible communication systems play in the formation and maintenance of cooperative partnerships in other alliance-forming animals.
