Due to the logistical and financial challenges in studying migratory marine species, there is relatively limited knowledge of the reproductive biology, behavior, and habitat use of many ecologically important marine megafauna species, including the Atlantic tarpon Megalops atlanticus. Here, we present a novel observation using consumer-grade aerial drones to observe, quantify the scale of, and classify behaviors within a previously unreported tarpon aggregation (N = 182) over the course of a 2-day fish aggregation event. After the event, we analysed and compared observed behaviors (e.

Annually, approximately 16% of adults aged 60 and older are victims of abuse in community settings. A critical first step toward effectively intervening and reducing the prevalence of elder abuse is to better understand the current state of knowledge, beliefs, and practices. This qualitative descriptive study explored the perceptions of US frontline community workers regarding elder abuse through focus groups and interviews conducted in the spring and summer of 2021.

Gene flow is important for maintaining the genetic diversity required for adaptation to environmental disturbances, though gene flow may be limited by site fidelity in small coastal sharks. Bonnethead sharks ()-a small coastal hammerhead species-demonstrate site fidelity, as females are philopatric while males migrate to mediate gene flow. Consequently, bonnetheads demonstrate population divergence with distance, and Atlantic populations are genetically distinct from those of the Gulf of Mexico.

Maternal investment theory is the study of how breeding females allocate resources between offspring size and brood size to achieve reproductive success. In classical trade-off models, r/K-selection and bet-hedging selection, the primary predictors of maternal investments in offspring are population density and resource stability. In crowded, stable environments, K-selected females invest in large offspring at an equivalent cost in brood size.

There is intense public interest surrounding the conservation and management of sharks, including a debate over whether sustainable shark fisheries are possible or fishing bans on sharks are needed to conserve these animals. An important but rarely discussed data point in discussions of global shark fisheries is the case of British Columbia's fishery for Pacific spiny dogfish, Squalus suckleyi, which in 2011 became the first Marine Stewardship Council-certified shark fishery anywhere in the world. A few years later, despite reportedly healthy local stocks and thriving global markets for this shark, the fishery voluntarily withdrew its MSC certification, and in recent years more than 95% of the quota for Pacific spiny dogfish has been left in the water.

We build on environmental attitude research to provide a foundation for considering policies making economic and environmental trade-offs. We conducted a large online survey of Florida public attitudes (n = 829), a state grappling with trade-offs between economic development and environmental quality. Findings provide the first baseline understanding of Floridian perceptions of relationships between key economic drivers and the environment.

Despite evidence of their importance to marine ecosystems, at least 32% of all chondrichthyan species are estimated or assessed as threatened with extinction. In addition to the logistical difficulties of effectively conserving wide-ranging marine species, shark conservation is believed to have been hindered in the past by public perceptions of sharks as dangerous to humans. Shark Week is a high-profile, international programming event that has potentially enormous influence on public perceptions of sharks, shark research, shark researchers, and shark conservation.

Environmental media discourse analysis allows researchers to explore thematic patterns in media coverage of environmental issues through qualitative observations and quantitative coding. In this paper, we review newspaper media coverage in Florida pertaining to the connections between agriculture, other non-point pollution sources, and downstream ecosystem health. We analyzed 930 articles from 2007 through 2019 to determine common patterns in how these issues are covered by Florida media, including patterns in the causes of environmental problems, potential solutions, and stakeholders mentioned.

Many species of sharks are threatened with extinction, and there has been a longstanding debate in scientific and environmental circles over the most effective and appropriate strategy to conserve and protect them. Should we allow for sustainable fisheries exploitation of species which can withstand fishing pressure, or ban all fisheries for sharks and trade in shark products? In the developing world, exploitation of fisheries resources can be essential to food security and poverty alleviation, and global management efforts are typically focused on sustainably maximizing economic benefits. This approach aligns with traditional fisheries management and the perspectives of most surveyed scientific researchers who study sharks.

Objective: To test the hypothesis that a culturally tailored sugar-sweetened beverage (SSB) campaign designed specifically for the Victorian Aboriginal community will not only be valuable for Aboriginal Victorians but will also have cross-over benefits for non-Aboriginal Victorians.

Methods: An online survey was completed by 155 Victorians (78 Aboriginal, 77 non-Aboriginal) four months after the Aboriginal Rethink Sugary Drink (RSD) advertisement was launched. Differences between Aboriginal and non-Aboriginal respondents were assessed using χ2 and Wilcoxon rank-sum tests.

Sharks are a taxon of significant conservation concern and associated public interest. The scientific community largely supports management policies focusing on sustainable fisheries exploitation of sharks, but many concerned members of the public and some environmental advocates believe that sustainable shark fisheries cannot and do not exist and therefore support total bans on all shark fisheries and/or trade in shark products. The belief that sustainable shark fisheries cannot and do not exist persists despite scientific evidence showing that they can and do, and are important to livelihoods.

The Rural Hastings Health Link coordinates care for the 1-5% of the local population whose complexity represents two-thirds of healthcare spending. Gateway Community Health Centre developed a primary care-led model with local partners in primary care and the broader health and social sector built on four interventions: a structure to support integrated system thinking with partners, system navigators embedded in primary care addressing medical and social needs, a digital care-coordination tool and data management supporting accountability. It has altered how providers respond to clients' needs and, as an integrated system of care, created a shared culture of change driven by trust.
