A serra da Bodoquena, localizada no Estado do Mato Grosso do Sul, apresenta particularidades nos seus solos, que diferem de outras regiões do bioma cerrado-pantanal. Este trabalho teve como objetivo ampliar o conhecimento dos solos formados sobre calcário, por meio da caracterização dos seus atributos físicos, químicos, mineralógicos e da matéria orgânica. Foi selecionada uma topossequência sobre calcário, onde foram abertas trincheiras no topo (P1), terço inferior (P2), sopé (P3) e baixada (P4 e P5). Os perfis foram descritos morfologicamente e analisados os atributos físicos, químicos e mineralógicos dos horizontes. de acordo com o Sistema Brasileiro de Classificação de Solos, os solos estudados foram classificados como: (P1) Organossolo Fólico Sáprico lítico - OOs; (P2) Chernossolo Háplico Órtico típico - MXo; (P3) Chernossolo Argilúvico Órtico típico - MTo; (P4) Gleissolo Melânico Carbonático chernossólico - GMk1; e (P5) Gleissolo Melânico Carbonático organossólico - GMk2. Todos os perfis estudados apresentaram cores escuras nos horizontes superficiais e mais avermelhadas ou acinzentadas em profundidade, em razão da drenagem, sempre associados com elevados valores de saturação por bases e tendo o cálcio como cátion predominante no complexo sortivo.

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Processo FAPESP: 11/06438-2; Processo FAPESP: 09/52725-3; Processo FAPESP: 09/17411-8; Premise of the study: Microsatellite primers were developed for Orthophytum ophiuroides, a rupicolous bromeliad species endemic to neotropical rocky fields. These microsatellite loci will be used to investigate population differentiation and species cohesion in such fragmented environments. The loci were tested for cross-amplification in related bromeliad species.Methods and Results: Eleven polymorphic microsatellite markers were isolated and characterized from an enriched library of O. ophiuroides. The loci were tested on 42 individuals from two populations of this species. The number of alleles per locus ranged from three to nine and the expected and observed heterozygosities ranged from 0.167 to 0.870 and from 0.369 to 0.958, respectively. Seven loci successfully amplified in other related bromeliad species.Conclusions: Our results suggest that the microsatellite loci developed here will be useful to assess genetic diversity and gene flow in O. ophiuroides for the investigation of population differentiation and species cohesion in neotropical mountainous habitats.

The diversity and spatio-temporal distribution of Elmidae (Coleoptera) assemblages in montane rivers and streams of southernmost Brazil (Rio Grande do Sul state) were studied. Six genera were found, represented mostly by larval specimens. Austrolimnius and Macrelmis are new occurrences in the region. Assemblages’ genera composition and dominance were related to the presence of the macrophyte Podostemum. Also, water temperature and stream depth and velocity were the most important drivers related to the assemblages’ distribution. Richness and abundance were positively related to high water velocity and negatively to stream depth. Temporal patterns were detected especially in assemblage abundance, yet a slight pattern in richness was also observed. The seasonal structure was related to warm temperatures, but temporal distribution of Elmidae assemblages appears to be related to the dominant genera life cycles. The studied area shows an overall Elmidae richness similar to that found in some tropical areas and the role of mountainous environments in sustaining high rates of regional diversity in the Neotropics is stated.

Emission of heavy metals from traffic activities is an important pollution source to roadside farmland ecosystems. However, little previous research has been conducted to investigate heavy metal concentrations of roadside farmland soil in mountainous areas. Owing to more complex roadside environments and more intense driving conditions on mountainous highways, heavy metal accumulation and distribution patterns in farmland soil due to traffic activity could be different from those on plain highways. In this study, design factors including altitude, roadside distance, terrain, and tree protection were considered to analyze their influences on Cu, Zn, Cd, and Pb concentrations in farmland soils along a mountain highway around Kathmandu, Nepal. On average, the concentrations of Cu, Zn, Cd, and Pb at the sampling sites are lower than the tolerable levels. Correspondingly, pollution index analysis does not show serious roadside pollution owing to traffic emissions either. However, some maximum Zn, Cd, and Pb concentrations are close to or higher than the tolerable level, indicating that although average accumulations of heavy metals pose no hazard in the region, some spots with peak concentrations may be severely polluted. The correlation analysis indicates that either Cu or Cd content is found to be significantly correlated with Zn and Pb content while there is no significant correlation between Cu and Cd. The pattern can be reasonably explained by the vehicular heavy metal emission mechanisms...

Terrorism is the greatest threat to national security and cannot be defeated by conventional military force alone. In critical areas such as Iraq, Afghanistan and Turkey, regular forces cannot reach these hostile/terrorist groups, the instigators of terrorism. These groups have a clear understanding of the relative ineffectiveness of counter-guerrilla operations and rely on guerrilla warfare to avoid major combat as their primary means of continuing the conflict with the governmental structures. In Internal Security Operations, detection of terrorist and hostile groups in their hiding places such as caves, lairs, etc. can only be achieved by professionally trained people such as Special Forces or intelligence units with the necessary experience and tools suitable for collecting accurate information in these often harsh, rugged and mountainous countries. To assist these forces, commercial micro-sensors with wireless interfaces could be utilized to study and monitor a variety of phenomena and environments from a certain distance for military purposes. In order to locate hidden terrorist groups and enable more effective use of conventional military resources, this paper proposes an active remote sensing model implanted into animals capable of living in these environments. By using these mobile sensor devices...

Populations of large carnivores can persist in mountainous environments following extensive land use change and the conversion of suitable habitat for agriculture and human habitation in lower lying areas of their range. The significance of these populations is poorly understood, however, and little attention has focussed on why certain mountainous areas can hold high densities of large carnivores and what the conservation implications of such populations might be. Here we use the leopard (Panthera pardus) population in the western Soutpansberg Mountains, South Africa, as a model system and show that montane habitats can support high numbers of leopards. Spatially explicit capture-recapture (SECR) analysis recorded the highest density of leopards reported outside of state-protected areas in sub-Saharan Africa. This density represents a temporally high local abundance of leopards and we explore the explanations for this alongside some of the potential conservation implications.

Much of the rural poor -- who are growing in number -- are concentrated in ecologically fragile and remote areas. The key ecological scarcity problem facing such poor households is a vicious cycle of declining livelihoods, increased ecological degradation and loss of resource commons, and declining ecosystem services on which the poor depend. In addition, developing economies with high concentrations of their populations on fragile lands and in remote areas not only display high rates of rural poverty, but also are some of the poorest countries in the world today. Policies to eradicate poverty therefore need to be targeted at the poor where they live, especially the rural poor clustered in fragile environments and remote areas. The specific elements of such a strategy include involving the poor in payment for ecosystem services schemes and other measures that enhance the environments on which the poor depend; targeting investments directly to improving the livelihoods of the rural poor, thus reducing their dependence on exploiting environmental resources; tackling the lack of access of the rural poor in less favored areas to well-functioning and affordable markets for credit...

These guidelines have three sections. Section one provides food for thought, regarding poverty and environment, and how the two are linked. Section two provides practical tools to incorporate the environment into a village-level action plan for the environment. Section three provides ideas for innovative activities relating to the environment in poverty reduction programs. Finally two practical checklists are provided: one for poverty reduction managers who wish to monitor progress in incorporating environment into staff work; and one for poverty reduction staff involved into village poverty reduction plans. The guidelines focus on Southwest China where poor areas are mostly mountainous areas. In other parts of China where poor areas are also arid areas, poverty reduction staff may use these guidelines as a reference but will need to adjust specific contents in section 2 to the different environmental issues of the region they work in.

Observation network design requires some framework for sensitivity studies. The goal is to place observations where they will reduce forecast error the most. We use uncertainty estimates from our best forecast models as an indicator of forecast error. The first step is then to find initial-state perturbations that reduce forecast uncertainty by minimizing a user-dependent norm. Adjoint models have helped meet this challenge for decades. More recently, ensemble sensitivities have emerged as a powerful alternative to adjoint models. Under the conditions of Gaussian statistics and an infinite ensemble, lagged covariances from an ensemble can be used equivalently to an adjoint model to give the least-squares minimization of a given cost function. One practical advantage is that costly development and maintenance of tangent linear and adjoint models are avoided. Ensemble sensitivities have been shown to be an effective alternative to adjoint models. They have been used successfully to diagnose predictors of forecast error in synoptic storms, extratropical transition and developing hurricanes. Because they rely on lagged covariances from a finite-sized ensemble, they are subject to sampling error and spurious covariances. However, their efficacy for high-resolution forecasts in mountainous environments has not been thoroughly explored. We present results from experiments designed to establish the potential for ensemble sensitivity computations with a high resolution mesoscale model (grid spacing 4 km) in complex terrain. Using the Weather Research and Forecast (WRF) model and the Data Assimilation Research Testbed (DART) we compute sensitivities with cost functions defined to emphasize parameters affecting fog forecasting in the boundary layer. High sensitivities are interpreted as indicating low predictability for forecasting in the mountains. Results from convergence studies reveal the ensemble sizes needed to robustly estimate the sensitivities. We comment on the implications of results for observation placement and on the expected impact of model inadequacy.

Approved for public release, distribution is unlimited; The modern battlefield is extremely lethal. Many weapons systems provide the capability to engage a target far in excess of the range at which positive target identification can be made. This capability increases the likelihood of inadvertent engagement of friendly forces or, fratricide. Numerous initiatives have been undertaken to provide solutions to reduce fratricide. These solutions generally focus in one of two areas: target identification or situational awareness. Several situational awareness systems are under development. The Marine Corps has explored the concept of improving situational awareness through a mobile network application; however, the requirements for this system are not well understood. One method of identifying the situational awareness requirements, which was used in this research, was through simulation. Three simulated combat environments were modeled (urban, mixed, and mountainous desert terrain) and the interaction of forces in the environments was observed. Based on the observations and the author's experience, conclusions were drawn about the requirements for a network situational awareness system. Principle findings of this research include system update rates...

Recent research in S E Asia and Vietnam in particular, funded by the World Bank and DfID since 2003, has focused on improving rural community access through more sustainable low volume rural road design. More appropriate design ensures that roads built are cost effective in terms of whole life performance. Because of increasing recognition that gravel surfacing was not always the best solution for rural roads in Vietnam, the initial research focused on the performance of existing unsealed roads and the identification of sustainable alternatives. Subsequent research has focused on the relative performance of the alternative option trials and their role in providing a more climate resilient rural infrastructure. In general, this work has concentrated on a range of pavements to establish the best performance within a range of physical and socio-economic environments. This note highlights the findings of the Rural Road Gravel Assessment Programme (RRGAP) and the Rural Road Surfacing Trials (RRST phases I, II and III) undertaken within Vietnam under the umbrella of the Ministry of Transport Rural Road Surfacing Research (RRSR) committee. Outcomes were enhanced by information from complimentary projects within Lao PDR and Cambodia.

Lesotho is one of the poorest and most unequal countries in the world. It is a small, mostly mountainous, and largely rural country of about 2 million people, completely surrounded by South Africa. The persistence of poverty and rising inequality are striking for an economy that grew at annual rates of 4 percent per capita over the past decade. Redefining the role of the state will be critical for meeting the twin goals through boosting inclusive growth and avoiding macroeconomic and social risks. In this context, this Systematic Country Diagnostic (SCD) is intended to assess development challenges and identify priorities for rapid progress in achieving the objectives of: (i) eliminating extreme poverty on a sustainable basis and (ii) ensuring shared prosperity by improving the welfare of Lesotho’s poorer citizens. The report analyzes the opportunities and challenges in meeting these objectives, focusing on growth, inclusiveness, and sustainability. The SCD concludes by prioritizing the key challenges. Lesotho has an opportunity to eradicate extreme poverty and boost shared prosperity in coming years. It will require shifting to a growth model led by an export-oriented private sector...

Although treeline elevations are limited globally by growing season temperature, at regional scales treelines frequently deviate below their climatic limit. The cause of these deviations relate to a host of climatic, disturbance, and geomorphic factors that operate at multiple scales. The ability to disentangle the relative effects of these factors is currently hampered by the lack of reliable topoclimatic data, which describe how regional climatic characteristics are modified by topographic effects in mountain areas. In this study we present an analysis of the combined effects of local- and regional-scale factors on southern beech treeline elevation variability at 28 study areas across New Zealand. We apply a mesoscale atmospheric model to generate local-scale (200 m) meteorological data at these treelines and, from these data, we derive a set of topoclimatic indices that reflect possible detrimental and ameliorative influences on tree physiological functioning. Principal components analysis of meteorological data revealed geographic structure in how study areas were situated in multivariate space along gradients of topoclimate. Random forest and conditional inference tree modelling enabled us to tease apart the relative effects of 17 explanatory factors on local-scale treeline elevation variability. Overall...

Triggered by a fascinating publication in the New England Journal of Medicine detailing China's new multi-pronged strategy to control and eventually interrupt the transmission of Schistosoma japonicum, this PLoS Neglected Tropical Diseases Debate critically examines the generalizability and financial costs of the studies presented from the marshlands of the lake region. Edmund Seto from the University of California and colleagues emphasize that the epidemiology and control of schistosomiasis varies according to the social-ecological context. They conjecture that the successful intervention packages piloted in the lake region is not fully fit for the hilly and mountainous environments in Sichuan and Yunnan provinces, and hence call for more flexible, setting-specific, and less expensive control strategies. In response, Xiao-Nong Zhou from the National Institute of Parasitic Diseases at the Chinese Center of Disease Control and Prevention and colleagues explain the steps from designing pilot studies to the articulation and implementation of a new national control strategy through a careful process of scaling-up and adaptations. Finally, the two opponents converge. The need for integrated, intersectoral, and setting-specific control measures is stressed...

Airborne laser scanning (ALS) is an active remote sensing technique that uses the time-of-flight measurement principle to capture the three-dimensional structure of the earth's surface with pulsed lasers that transmit nanosecond-long laser pulses with a high pulse repetition frequency. Over forested areas most of the laser pulses are reflected by the leaves and branches of the trees, but a certain fraction of the laser pulses reaches the forest floor through small gaps in the canopy. Thus it is possible to reconstruct both the three-dimensional structure of the forest canopy and the terrain surface. For the retrieval of quantitative forest parameters such as stem volume or biomass it is necessary to use models that combine ALS with inventory data. One approach is to use multiplicative regression models that are trained with local inventory data. This method has been widely applied over boreal forest regions, but so far little experience exists with applying this method for mapping alpine forest. In this study the transferability of this approach to a 128 km2 large mountainous region in Vorarlberg, Austria, was evaluated. For the calibration of the model, inventory data as operationally collected by Austrian foresters were used. Despite these inventory data are based on variable sample plot sizes...

Aim: The environments that existed in south-east Asian islands during the last glacial are poorly known, limiting our understanding of mammalian biogeography in the region. The objective of this research is to investigate the ecological characteristics of mammal faunas on small islands, and to see whether the habitat requirements of the species in those faunas can be used to deduct the vegetation types that existed on islands before becoming isolated by rising sea levels. Location: The maps presented here cover the small islands of tropical south-east Asia, including the Burmese, Thai and Cambodian islands in the north, the islands off the coast of west Sumatra in the west, the islands around Java in the south, and the islands off the east coast of Borneo in the east, including the Philippine islands of Palawan and those in the Sulu Archipelago. Methods: The presence records of mammal species on 215 small islands in the region were compiled, and the habitat requirements for each of these species was assessed (species that had probably been introduced by humans were excluded from the analysis). For each island location (longitude and latitude), maximum altitude of the island, total area, depth to nearest land, distance to nearest island...

Priority Areas for Conservation are defined in order to protect environments that are home to a richness of species, endemisms and/or endangered species. However, besides these factors, additional studies such as Environmental Perception of local communities and Landscape Analysis are relevant to assess and minimize the negative effects caused to natural environments. In this context and in this perspective, the Mountain Range Complex João do Vale was studied, located in the state of Rio Grande do Norte, which holds a set of landscapes with different vegetation types that are being replaced by various economic activities resulting from disordered population growth and consequent exploitation of natural resources' potential. The use of these resources, in most cases, occurs improperly, leading to a depletion of this potential. This study proposes to combine Analysis of Landscape, through a Geographic Information System (GIS), to the Environmental Perception of rural communities in order to define Priority Areas for Conservation. Perception data were obtained through direct observation, questioning, interviews and application forms (n = 240); as to the landscape, data from slope maps, Permanent Preservation Areas (PPA) and Environmental Vulnerability were used. The Content Analysis used for perception data showed that respondents have a sense of topophilia regarding where they live...
