Networks of marine reserves are increasingly being promoted as a means of conserving marine biodiversity. One consideration in designing systems of marine reserves is the maintenance of connectivity to ensure the long-term persistence and resilience of populations. Knowledge of connectivity, however, is frequently lacking during marine reserve design and establishment. We characterise patterns ...

According to risk systems theory and the characteristics of the chemical industry, an index system was established for risk assessment of enterprises in chemical industrial parks (CIPs) based on the inherent risk of the source, effectiveness of the prevention and control mechanism, and vulnerability of the receptor. A comprehensive risk assessment method based on catastrophe theory was then pro...

Although livestock anthrax is declining in many parts of the world, with an increasing number of countries probably truly free of the disease, anthrax remains enzootic in many national parks and even in some game ranching areas. These infected areas can present a persistent risk to surrounding livestock, which may otherwise be free of the disease, as well as a public health risk. The authors us...

Only 25-35% of Canadian children and youth regularly engage in active transportation (AT; e.g., non-motorized travel modes such as walking and cycling) to/from school. Previous research shows that distance between home and school is the strongest barrier to AT. Based on social ecological theory, we describe several strategies to overcome this barrier. At the individual level, children and youth...

As limited-control dog parks become more popular, concerns arise about whether these parks encourage interdog aggression. Systematic observations made at 1 park over 72 hr across 8 months found that 28 conflicts or potential conflicts occurred (< 0.5%). Of these, 14 were clear aggressive episodes. Each lasted less than 1 min (< 0.33% of total observation time). There were 14 other incidents of ...

The concept of crowdsourcing sounds like a potentially useful method to gather information collectively contributed by a group of individuals. However, how willing would individuals actually be in contributing information in reality? This paper primarily presents the findings from a visitor survey conducted at a prominent National Park in Victoria, Australia, as part of a research project. The ...
