Necromass in forests of Madre de Dios, Peru: A comparison between terra firme and lowland forests
(Universidad Nacional Mayor de San Marcos, Facultad de Ciencias Biológicas, 2011-04-01)Stocks of dead wood or necromass represent an important portion of biomass and nutrients in tropical forests. The objectives of this study were: 1) to evaluate and compare the necromass of “terra firme” and lowlands forests, ... -
Killing squirrels: Exploring motivations and practices of lethal wildlife management
(Sage, 2018-03-07)Wildlife management, pest control and conservation projects often involve killing nonhuman animals. In the United Kingdom, introduced grey squirrels Sciurus carolinensis are killed in large numbers to protect remnant ... -
Invasive species management will benefit from social impact assessment
(Wiley, 2016-11-14)Invasive species management aims to prevent or mitigate the impacts of introduced species but management interventions can themselves generate social impacts that must be understood and addressed. Established approaches ... -
Placing Early Photography: The Work of Robert Hunt in Mid-Nineteenth-Century Britain
(Taylor & Francis (Routledge), 2017-11-28)The invention of photography in the late 1830s is conventionally framed in terms of simultaneous rival developments by a few well-known figures in England and France. Less attention has been paid to how early photography ... -
Long Term Planetary Habitability and the Carbonate-Silicate Cycle
(Mary Ann Liebert, 2018)The potential habitability of an exoplanet is traditionally assessed by determining whether or not its orbit falls within the circumstellar ‘habitable zone' of its star, defined as the distance at which water could be ... -
Gaian bottlenecks and planetary habitability maintained by evolving model biospheres: The ExoGaia model
(Oxford University Press, 2018-03-14)The search for habitable exoplanets inspires the question - how do habitable planets form? Planet habitability models traditionally focus on abiotic processes and neglect a biotic response to changing conditions on an ... -
Abrupt Climate Change in an Oscillating World.
(Nature Publishing Group, 2018-03-22)The notion that small changes can have large consequences in the climate or ecosystems has become popular as the concept of tipping points. Typically, tipping points are thought to arise from a loss of stability of an ... -
Orbital-scale climate forcing of grassland burning in southern Africa.
(National Academy of Sciences, 2013-03-26)Although grassland and savanna occupy only a quarter of the world's vegetation, burning in these ecosystems accounts for roughly half the global carbon emissions from fire. However, the processes that govern changes in ... -
Pollen from the deep-sea: A breakthrough in the mystery of the Ice Ages
(Frontiers Media, 2018)Pollen from deep-sea sedimentary sequences provides an integrated regional reconstruction of vegetation and climate (temperature, precipitation and seasonality) on the adjacent continent. More importantly, the direct ... -
The ACER pollen and charcoal database: A global resource to document vegetation and fire response to abrupt climate changes during the last glacial period
(Copernicus Publications, 2017-09-11)Quaternary records provide an opportunity to examine the nature of the vegetation and fire responses to rapid past climate changes comparable in velocity and magnitude to those expected in the 21st-century. The best ... -
Climate change and the global pattern of moraine-dammed glacial lake outburst floods
(European Geosciences Union (EGU) / Copernicus Publications, 2018-04-09)Despite recent research identifying a clear anthropogenic impact on glacier recession, the effect of recent climate change on glacier-related hazards is at present unclear. Here we present the first global spatio-temporal ... -
Will fire danger be reduced by using Solar Radiation Management to limit global warming to 1.5°C compared to 2.0°C
(American Geophysical Union, 2018-04-06)The commitment to limit warming to 1.5°C as set out in the Paris Agreement is widely regarded as ambitious and challenging. It has been proposed that reaching this target may require a number of actions, which could include ... -
Engaging stakeholders in research to address water-energy-food (WEF) nexus challenges
(Springer Verlag, 2018-04-04)The water–energy–food (WEF) nexus has become a popular, and potentially powerful, frame through which to analyse interactions and interdependencies between these three systems. Though the case for transdisciplinary research ... -
Genetic diversity in the Andes: variation within and between the South American species of Oreobolus R. Br. (Cyperaceae)
(Springer Verlag, 2017-09-05)This study examines genetic relationships among and within the South American species of Oreobolus that span the temperate and tropical Andes hotspots and represent a good case study to investigate diversification in the ... -
Comment on “The extent of forest in dryland biomes”
(American Association for the Advancement of Science, 2017-11-17)Bastin et al. (Reports, 12 May 2017, p. 635) infer forest as more globally extensive than previously estimated using tree cover data. However, their forest definition does not reflect ecosystem function or biotic composition. ... -
Dispersal, isolation and diversification with continued gene flow in an Andean tropical dry forest.
(Wiley, 2017-06-20)The Andes are the world's longest mountain chain, and the tropical Andes are the world's richest biodiversity hot spot. The origin of the tropical Andean cordillera is relatively recent because the elevation of the mountains ... -
Coevolutionary arms race versus host defense chase in a tropical herbivore–plant system
(National Academy of Sciences, 2017-09-05)Coevolutionary models suggest that herbivores drive diversification and community composition in plants. For herbivores, many questions remain regarding how plant defenses shape host choice and community structure. We ... -
Plant diversity patterns in neotropical dry forests and their conservation implications
(American Association for the Advancement of Science, 2016-09-23)Seasonally dry tropical forests are distributed across Latin America and the Caribbean and are highly threatened, with less than 10% of their original extent remaining in many countries. Using 835 inventories covering 4660 ... -
Dispersal assembly of rain forest tree communities across the Amazon basin
(National Academy of Sciences, 2017-03-07)We investigate patterns of historical assembly of tree communities across Amazonia using a newly developed phylogeny for the species-rich neotropical tree genus Inga. We compare our results with those for three other ... -
Global Carbon Budget 2017
(Copernicus Publications, 2018-03-12)Accurate assessment of anthropogenic carbon dioxide (CO 2 ) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere-the "global carbon budget"-is important to better understand the global ...
