A horizon scan of global conservation issues for 2014
This paper presents the output of our fifth annual horizon-scanning exercise, which aims to identify topics that increasingly may affect conservation of biological diversity, but have yet to be widely considered. A team of professional horizon scanners, researchers, practitioners, and a journalist identified 15 topics which were identified via an iterative, Delphi-like process. The 15 topics include a carbon market induced financial crash, rapid geographic expansion of macroalgal cultivation, genetic control of invasive species, probiotic therapy for amphibians, and an emerging snake fungal disease. © 2013 Elsevier Ltd
A 2018 Horizon Scan of Emerging Issues for Global Conservation and Biological Diversity.
This is our ninth annual horizon scan to identify emerging issues that we believe could affect global biological diversity, natural capital and ecosystem services, and conservation efforts. Our diverse and international team, with expertise in horizon scanning, science communication, as well as conservation science, practice, and policy, reviewed 117 potential issues. We identified the 15 that may have the greatest positive or negative effects but are not yet well recognised by the global conservation community. Themes among these topics include new mechanisms driving the emergence and geographic expansion of diseases, innovative biotechnologies, reassessments of global change, and the development of strategic infrastructure to facilitate global economic priorities
9 - Life-history and Reproductive Strategies of Bats
The timing and frequency of reproduction are major determinants of life-history strategies, which have evolved to maximize lifetime reproductive output, and thus to maximize fitness in terms of an individual\u27s genetic contribution to the next generation. Bats have distinctive life-history strategies for mammals of their size. Most small animals have evolved a âlive fast - die youngâ strategy, characterized by rapid reproduction and high mortality. In contrast, bats generally have a life history characterized by longevity with multiple reproductive events, low litter size and delayed onset of sexual maturity. Typically a single young is produced, although twins are common in some species. The trend for smaller mammals to generally produce relatively larger young reaches its extreme in bats, in which the neonate may weigh up to 43% of maternal mass. Coupled with one of the lowest mass-specific fetal growth rates recorded within mammals, bats are characterized by long gestation lengths for mammals of their size. This is followed by a relatively long period of lactation and post-natal care. Longer gestation, coupled with a shorter period of lactation, may reflect lower energetic investment per day in gestation, compared to the high costs of lactation, and may represent a strategy by which energetic investment in young is optimized in relation to seasonal food abundance

A Horizon Scan of Emerging Global Biological Conservation Issues for 2020.
In this horizon scan, we highlight 15 emerging issues of potential relevance to global conservation in 2020. Seven relate to potentially extensive changes in vegetation or ecological systems. These changes are either relatively new, for example, conversion of kelp forests to simpler macroalgal systems, or may occur in the future, for example, as a result of the derivation of nanocelluose from wood or the rapid expansion of small hydropower schemes. Other topics highlight potential changes in national legislation that may have global effect on international agreements. Our panel of 23 scientists and practitioners selected these issues using a modified version of the Delphi technique from a long-list of 89 potential topics.NERC and RSPB fundin
A horizon scan of global conservation issues for 2015
This paper presents the results of our sixth annual horizon scan, which aims to identify phenomena that may have substantial effects on the global environment, but are not widely known or well understood. A group of professional horizon scanners, researchers, practitioners, and a journalist identified 15 topics via an iterative, Delphi-like process. The topics include a novel class of insecticide compounds, legalisation of recreational drugs, and the emergence of a new ecosystem associated with ice retreat in the Antarctic
