Abstract Breeding technology is of utmost importance for reproduction of wild fish in captivity for the reintroduction and selective breeding programs purposes. The main challenge is that when applied to wild undomesticated specimens, conventional protocols often cause breeders and/or embryo mortality ...
From current theories on life-history evolution, fast early-life growth to reach early reproduction in heavily hunted populations should be favored despite the possible occurrence of mortality costs later on. However, fast growth may also be associated with better individual quality and thereby lower ...
Understanding and communicating the links among human activities and marine ecosystem services are fundamental for ecosystem-based management, which aims at attaining ecological, economic and social sustainability in the use of our seas. Relationships are typically complex and may differ between geographic ...
Plastics, owing to their various beneficial properties (durability, flexibility and lightweight nature), are widely regarded as the workhorse material of our modern society. Being ubiquitously and increasingly present over the past 60 years, they provide various benefits to the global economy. However, ...
Increased concentrations of phosphorus (P) in riverine systems lead to eutrophication and can contribute to other environmental effects. Chalk rivers are known to be particularly sensitive to elevated P levels. We used high-frequency (daily) automatic water sampling at five distinct locations in the ...
In the immediate aftermath of disaster, governments usually act quickly to reduce risk and to recover their communities’ socio-economic functioning. Policy makers in these situations need—but may not have the capacity or time for—substantial analysis and public debate about how to balance short- and ...
Objective: to know the prevalence of occupational accidents in children and youth who work with their families in the rural environment and to identify the associated factors. Method: exploratory, descriptive and analytical study with quantitative approach, developed in three rural areas. Participants ...
Access to food has been determined to be a factor that strongly influences the dietary intake and eating habit of indigenous people (Orang Asli, OA). This study explored food acquisition and the barriers in obtaining traditional and market foods among the Jahai subtribe (within the Negrito ethnic group) ...
Key Takeaways Approximately two-thirds of the 2016 U.S. imports originated in countries with workplaces less safe than those in the U.S. The U.S. has failed to achieve the low fatal injury rates attained by some top importing countries. Readers are asked to reflect on how the U.S. can share its knowledge ...
Ecological resilience describes systems that have the capacity to recover after a complete collapse of system function. For a system to be ecologically resilient, system collapse is accepted as being inevitable and requires that the resources for subsequent system recovery be buried in the wreckage ...
The use of environmental data to support science, technology, and marine operations has evolved dramatically owing to long-term ocean observatories, unmanned platforms, satellite and coastal remote sensing, data assimilative numerical models, and high-speed communications. Actionable environmental information ...
The broad outline of a Cyber Republic should have emerged by now. Many details are still missing, but the purpose of this book has been to provide a first iteration, an imperfect yet adequate paper prototype to trigger a broader discussion for an evolved system of liberal government fit for the Fourth ...
Artificial intelligence is opening up many new and exciting ways to improve environmental management. AI is certainly not a panacea. The applications of intelligent automation and machine learning tend to reflect the same technocentric and anthropocentric biases of ecosystem management more generally. ...
Rapid urbanization, marked by massive land-use and land-cover change (LUCC) and explosive population growth, has a significant impact on human activities. To provide a comprehensive understanding of the characteristics of LUCC in the Zhoushan Archipelago, dynamic monitoring and analysis of LUCC was ...
Moving target detection is of vital importance to maritime security and maritime resource protection. However, the detection of slow or weak targets is difficult based on traditional methods. A new detection method is proposed by using the different motion variations of radar moving target and sea clutter ...
With elaborate reviews and on-site investigations, this paper systematically depicts the water resource status of Jaffna Peninsula from perspectives of both lagoon water and groundwater. The main problems that local government faced in water resources development and utilization process are heterogeneity ...
the coastal zone is a zone where the ocean and the land meets, which is also the "life belt" of today's human social and economic development. Due to the impact of global climate change, the ecological environment of the coastal zone is seriously threatened. This paper briefly describes the corresponding ...
Hong Kong’s port is one of the busiest in the world. Such heavy traffic is associated with a high accident rate. The present study uses Bayesian Networks to analyze accident risk in Hong Kong waters using 331 accident reports during the period of 1999-2017. The methodology adopted is comprised of an ...
