A novel approach to assess livestock management effects on biodiversity of drylands
(Ecological Indicators, 2015-01-01)In drylands livestock grazing is the main production activity, but overgrazing due to mismanagement is a major cause of biodiversity loss. Continuous grazing around water sources generates a radial gradient of grazing intensity ... -
Assessing the effects of elephant foraging on the structure and diversity of an Afrotropical forest
(Biotropica, 2020-05-01)African forest elephants (Loxodonta cyclotis) are ecosystem engineers that browse and damage large quantities of vegetation during their foraging and movement. Though elephant trail networks and clearings are conspicuous ... -
Biomass offsets little or none of permafrost carbon release from soils, streams, and wildfire: An expert assessment
(Environmental Research Letters, 2016-03-07)As the permafrost region warms, its large organic carbon pool will be increasingly vulnerable to decomposition, combustion, and hydrologic export. Models predict that some portion of this release will be offset by increased ... -
Boom and bust carbon-nitrogen dynamics during reforestation
(Ecological Modelling, 2017-09-24)© 2017 Elsevier B.V. Legacies of historical land use strongly shape contemporary ecosystem dynamics. In old-field secondary forests, tree growth embodies a legacy of soil changes affected by previous cultivation. Three patterns ... -
Changes in evapotranspiration and phenology as consequences of shrub removal in dry forests of central Argentina
(Ecohydrology, 2015-10-01)More than half of the dry woodlands (forests and shrublands) of the world are in South America, mainly in Brazil and Argentina, where in the last years intense land use changes have occurred. This study evaluated how the ... -
Climate and health impacts of US emissions reductions consistent with 2 °C
(Nature Climate Change, 2016-05)© 2016 Macmillan Publishers Limited. All rights reserved. An emissions trajectory for the US consistent with 2 °C warming would require marked societal changes, making it crucial to understand the associated benefits. Previous ... -
Climate change challenges the current conservation strategy for the giant panda
(Biological Conservation, 2015-10-01)The global total of protected areas to conserve biodiversity is increasing steadily, while numerous studies show that they are broadly effective. That said, how will current conservation strategies work, given the current ... -
Climate science strategy of the US National Marine Fisheries Service

Climatic and Resource Determinants of Forest Elephant Movements
(Frontiers in Ecology and Evolution, 2020-04-17)As a keystone megafaunal species, African forest elephants (Loxodonta cyclotis) influence the structure and composition of tropical forests. Determining the links between food resources, environmental conditions and elephant ... -
Comparing Stakeholder Perceptions With Empirical Outcomes From Negotiated Rulemaking Policies: Is Participant Satisfaction a Proxy for Policy Success?
(Marine Policy, 2016)Evaluation of natural resource management policies often is made difficult by lack of robust or long-term data on the resource. In the absence of empirical data, natural resource policy evaluation may rely on expert ... -
Conceptualizing and operationalizing human wellbeing for ecosystem assessment and management
(Environmental Science and Policy, 2016-12-01)© 2016 Elsevier Ltd There is growing interest in assessing the effects of changing environmental conditions and management actions on human wellbeing. A challenge is to translate social science expertise regarding these ... -
Contribution of Subsidies and Participatory Governance to Fishers’ Adaptive Capacity
(Journal of Environment and Development, 2016-12-01)© 2016, © The Author(s) 2016. The need for strengthening fishers' adaptive capacity has been proposed in the literature as an important component of effective fisheries governance arrangements in the presence of rising numbers ... -
Convergent evolution in lemur environmental niches
(Journal of Biogeography, 2020-04-01)Aim: To test the hypothesis that adaptive convergent evolution of climate niches occurred in multiple independent lemur lineages. Location: Madagascar. Taxon: Lemurs. Methods: I collected climate and altitude data from WorldClim ... -
Creating linked datasets for SME energy-assessment evidence-building: Results from the U.S. Industrial Assessment Center Program
(Energy Policy, 2017-12-01)© 2017 Elsevier Ltd Lack of information is commonly cited as a market failure resulting in an energy-efficiency gap. Government information policies to fill this gap may enable improvements in energy efficiency and social ... -
Defaunation of large mammals alters understory vegetation and functional importance of invertebrates in an Afrotropical forest
(Biological Conservation, 2020-01-01)Hunting has reduced or eliminated large-bodied vertebrates in many areas across the tropics, contributing to the global process of defaunation. Elucidating the ecological consequences of hunting has important implications ... -
Defining Small-Scale Fisheries and Examining the Role of Science in Shaping Perceptions of Who and What Counts: A Systematic Review
(Frontiers in Marine Science, 2019-05-07) -
Deforestation risks posed by oil palm expansion in the Peruvian Amazon
(Environmental Research Letters, 2018-11-01)Further expansion of agriculture in the tropics is likely to accelerate the loss of biodiversity. One crop of concern to conservation is African oil palm (Elaeis guineensis). We examined recent deforestation associated with ... -
Describing the diversity of community supported fishery programs in North America
(Marine Policy, 2016-04-01)© 2016 Elsevier Ltd. This research investigates organizational diversity within Community Supported Fisheries (CSFs) in North America. Generally understood as the direct marketing of seafood through pre-arranged deliveries, ... -

DNA barcoding exposes a case of mistaken identity in the fern horticultural trade.
(Molecular ecology resources, 2010-11)Using cheilanthoid ferns, we provide an example of how DNA barcoding approaches can be useful to the horticultural community for keeping plants in the trade accurately identified. We use plastid rbcL, atpA, and trnG-R sequence ...
