Abstract Thousands of small populations are at increased risk of extinction because genetics and evolutionary biology are not well-integrated into conservation planning–a major lost opportunity for effective actions. We propose that if the risk of outbreeding depression is low, the default should be to evaluate restoration of gene flow to small inbred populations of diploid outbreeding organisms that were isolated by human activities within the last 500 years, rather than inaction. We outline the elements of a scientific-based genetic management policy for fragmented populations of plants and animals, and discuss the reasons why the current default policy is, inappropriately, inaction.

Abstract Conservation management is strongly shaped by the interpretation of population trends. In the Serengeti ecosystem, Tanzania, aerial total counts indicate a striking increase in elephant abundance compared to all previous censuses. We developed a simple age-structured population model to guide interpretation of this reported increase, focusing on three possible causes: (1) in situ population growth, (2) immigration from Kenya, and (3) differences in counting methodologies over time. No single cause, nor the combination of two causes, adequately explained the observed population growth. Under the assumptions of maximum in situ growth and detection bias of 12.7% in previous censuses, conservative estimates [...]

Abstract Cities are increasingly considered important places for biodiversity conservation because they can harbor threatened species and because conservation in cities represents an opportunity to reconnect people with nature and the range of health and well-being benefits it provides. However, urbanization can be catastrophic for native species, and is a well-known threat to biodiversity worldwide. Urbanization impacts can be mitigated by urban design and development improvements, but take-up of these practices has been slow. There is an urgent need to incorporate existing ecological knowledge into a framework that can be used by planners and developers to ensure that biodiversity conservation is [...]

Abstract The Earth's oceans are inherently 3-D in nature. Many physical, environmental, and biotic processes vary widely across depths. In recent years, human activities, such as oil drilling, mining, and fishing are rapidly expanding into deeper frontier ocean areas, where much of the biodiversity remains unknown. Most current conservation actions, management decisions and policies of both the pelagic and benthic domains do not explicitly incorporate the 3-D nature of the oceans and are still based on a two-dimensional approach. Here, we review current advances in marine research and conservation, aiming to advance towards incorporating the third dimension in marine systematic conservation [...]
