Noninvasive sampling reveals short-term genetic rescue in an insular red fox population.

J Hered 2019 Apr 19. Epub 2019 Apr 19.

Mammalian Ecology and Conservation Unit, Veterinary Genetics Laboratory; Department of Population Health and Reproduction; School of Veterinary Medicine, University of California, Davis, Davis, CA.

Genetic factors in the decline of small populations are extremely difficult to study in nature. We leveraged a natural experiment to investigate evidence of inbreeding depression and genetic rescue in a remnant population of subalpine-specialized Sierra Nevada red foxes (Vulpes vulpes necator) using noninvasive genetic monitoring during 2010-2017. Only 7 individuals were detected in the first 2 years. Read More

Wood Growth in Pure and Mixed L. Forests: Drought Influence Depends on Site Conditions.

Front Plant Sci 2019 2;10:397. Epub 2019 Apr 2.

Department of Agricultural Sciences, University of Naples Federico II, Naples, Italy.

Climate response of tree-species growth may be influenced by intra- and inter-specific interactions. The different physiological strategies of stress response and resource use among species may lead to different levels of competition and/or complementarity, likely changing in space and time according to climatic conditions. Investigating the drivers of inter- and intra-specific interactions under a changing climate is important when managing mixed and pure stands, especially in a climate change hot spot such as the Mediterranean basin.

Direct-acting antivirals and visceral leishmaniasis: a case report.

BMC Infect Dis 2019 Apr 18;19(1):328. Epub 2019 Apr 18.

Dipartimento di Scienze per la promozione della Salute e Materno-infantile, Università di Palermo, Palermo, Italy.

Background: Visceral leishmaniasis is a vector-borne parasitic disease caused by protozoa belonging to the genus Leishmania. The clinical presentation of visceral leishmaniasis strictly depends on the host immunocompetency, whereas depressive conditions of the immune system impair the capability to resolve the infection and allow reactivation from sites of latency of the parasite.

Case Presentation: We describe a case of visceral leishmaniasis (VL) that occurred in a patient with chronic hepatitis C treated with direct-acting antiviral drugs (DAA). Read More

Spatiotemporal Variability of Asymmetric Daytime and Night-Time Warming and Its Effects on Vegetation in the Yellow River Basin from 1982 to 2015.

Sensors (Basel) 2019 Apr 17;19(8). Epub 2019 Apr 17.

Department of Geosciences, Mississippi State University, Starkville, MS 39762, USA.

Temperatures from 1982 to 2015 have exhibited an asymmetric warming pattern between day and night throughout the Yellow River Basin. The response to this asymmetric warming can be linked to vegetation growth as quantified by the NDVI (Normalized Difference Vegetation Index). In this study, the time series trends of the maximum temperature () and the minimum temperature () and their spatial patterns in the growing season (April-October) of the Yellow River Basin from 1982 to 2015 were analyzed.

Dynamic environment-induced multistability and critical transition in a metacommunity ecosystem.

Phys Rev E 2019 Mar;99(3-1):032216

Department of Mathematics, Indian Institute of Technology Ropar, Rupnagar 140 001, Punjab, India.

We study a metacommunity model of consumer-resource populations coupled via dispersal under an environment-dependent framework, and we explore the occurrence of multistability and critical transition. By emphasizing two magnitudes acting on a dynamic environment at temporal and spatial scales, the coupled system with simple diffusive coupling and the nonlinear environmental coupling enables various interesting complex dynamics such as bistability, multistability, and critical transitions. Using the basin stability measure, we find the probability of attaining each alternative state in a multistable region. Read More

Land cover change explains the increasing discharge of the Paraná River.

Reg Environ Change 2018 9;18(6):1871-1881. Epub 2018 Apr 9.

1Sustainability Science Program, Kennedy School of Government, Harvard University, Cambridge, MA USA.

Over the past 40 years, the discharge in South America's Paraná River basin has increased despite no evidence of significant rainfall increases in the basin. In this analysis, we show that the observed multi-decadal increase in discharge can be explained by concomitant changes in land cover that have occurred within the basin during this period. Our analysis also indicates that the peak discharge timing may have shifted concurrently from January/February in the 1970s to March in more recent decades. Read More

The role of atmospheric internal variability on the prediction skill of interannual North Pacific sea-surface temperatures.

Theor Appl Climatol 2018 6;133(1):113-121. Epub 2017 Jun 6.

1Atmospheric, Oceanic, and Earth Sciences, George Mason University, Fairfax, VA USA.

The sensitivity of the sea-surface temperature (SST) prediction skill to the atmospheric internal variability (weather noise) in the North Pacific (20-60N;120E-80W) on decadal timescales is examined using state-of-the-art Climate Forecasting System model version 2 (CFS) and a variation of CFS in an Interactive Ensemble approach (CFSIE), wherein six copies of atmospheric components with different perturbed initial states of CFS are coupled with the same ocean model by exchanging heat, momentum and fresh water fluxes dynamically at the air-sea interface throughout the model integrations. The CFSIE experiments are designed to reduce weather noise and using a few ten-year long forecasts this study shows that reduction in weather noise leads to lower SST forecast skill. To understand the pathways that cause the reduced SST prediction skill, two twenty-year long forecasts produced with CFS and CFSIE for 1980-2000 are analyzed for the ocean subsurface characteristics that influence SST due to the reduction in weather noise in the North Pacific.

A small caseid synapsid, gen. et sp. nov., from the early Permian of Oklahoma, with a discussion of synapsid diversity at the classic Richards Spur locality.

Authors:
Robert R Reisz

PeerJ 2019 11;7:e6615. Epub 2019 Apr 11.

International Centre of Future Science, Jilin University, Changchun, Jilin, China.

The fossil record of caseids, a clade of faunivorous to large herbivorous Permian synapsids, is unusual in having a poorly documented history. Although Kungurian caseids are common in the well-known continental deposits of North America, and the fossil record of the group extends into the middle Permian (Guadalupian), with the presence of the large caseid in the Mezen Basin faunal assemblage, only two other occurrences are known in older Permian age sediments. One is an undescribed caseid from the Bromacker Quarry in Germany, and the second is from the lower Permian of Richards Spur, Oklahoma. Read More

Geographic shifts in Aedes aegypti habitat suitability in Ecuador using larval surveillance data and ecological niche modeling: Implications of climate change for public health vector control.

PLoS Negl Trop Dis 2019 Apr 17;13(4):e0007322. Epub 2019 Apr 17.

Quantitative Disease Ecology and Conservation (QDEC) Lab Group, Department of Geography, University of Florida, Gainesville, Florida, United States of America.

Arboviral disease transmission by Aedes mosquitoes poses a major challenge to public health systems in Ecuador, where constraints on health services and resource allocation call for spatially informed management decisions. Employing a unique dataset of larval occurrence records provided by the Ecuadorian Ministry of Health, we used ecological niche models (ENMs) to estimate the current geographic distribution of Aedes aegypti in Ecuador, using mosquito presence as a proxy for risk of disease transmission. ENMs built with the Genetic Algorithm for Rule-Set Production (GARP) algorithm and a suite of environmental variables were assessed for agreement and accuracy. Read More

Development of an annual drought classification system based on drought severity indexes.

An Acad Bras Cienc 2019 8;91(1):e20180188. Epub 2019 Apr 8.

Instituto Federal de Educação, Ciência e Tecnologia do Espírito Santo, Unidade Colatina, Av. Arino Gomes Leal, 1700, Santa Margarida, 29700-060 Colatina, ES, Brazil.

In order to characterize the occurrence and intensity of droughts in the Doce River Basin, as well as to develop a system for its classification, four different drought indexes were evaluated: Percent of Normal Precipitation (PNP), Deciles Method (DM), Rainfall Anomaly Index (RAI) and Standardized Precipitation Index (SPI). The indices were calculated annually, based on precipitation data from 89 rainfall stations of the Brazilian National Water Agency (ANA). Nine analysis units (AUs) were determined in the basin and the Thiessen Polygons method was used to obtain the average precipitation in the respective drainage areas. Read More

Neotectonics as a structural control of the boundaries of the Pantanal Matogrossense Sub-Regions.

An Acad Bras Cienc 2019 8;91(1):e20170697. Epub 2019 Apr 8.

Laboratório de Geoprocessamento para Aplicações Ambientais, Faculdade de Engenharias, Arquitetura e Urbanismo e Geografia, Universidade Federal de Mato Grosso do Sul, Cidade Universitária, s/n, 79070-900 Campo Grande, MS, Brazil.

Characterized by fluvio-alluvial sedimentation processes, the heterogeneity in the Pantanal Basin allows its division in several sub-regions, which present natural characteristics of their own. It is possible to find in the literature different proposals to subdivide the Pantanal plain, which vary in total area and number of sub-regions. Each author uses specific criteria - mainly vegetation, soil and humidity - in his delimitation, but does not consider the tectonic aspects of the basin. Read More

Vegetation dynamics of abandoned paddy fields and surrounding wetlands in the lower Tumen River Basin, Northeast China.

PeerJ 2019 8;7:e6704. Epub 2019 Apr 8.

Department of Ecosystem Studies, Graduate School of Agricultural and Life Sciences, University of Tokyo, Tokyo, Japan.

On the temperate lowland plain of the lower Tumen River, agricultural development has converted most marshland into paddy fields. However, the locations of old paddy fields in the lowland temperate zone, where the vegetation structure is dominated by herbs adapted to seasonally wet or waterlogged conditions, are poorly known, and the impact of land use history on marshland diversity and shifts in plant functional groups has been scantly researched. In this study, we used a chronosequence approach to investigate herbaceous wetland communities in different recovery phases (<5 years, 5-15 years, and >15 years), as well as natural wetland as a reference.

Water quality modelling of the Mekong River basin: Climate change and socioeconomics drive flow and nutrient flux changes to the Mekong Delta.

Sci Total Environ 2019 Apr 6;673:218-229. Epub 2019 Apr 6.

Southern Institute of Water Resources Research (SIWRR), Research Centre for Rural Infrastructure Engineering Development, 658th Vo Van Kiet avenue Dist.5 HCMC, Viet Nam.

The Mekong delta is recognised as one of the world's most vulnerable mega-deltas, being subject to a range of environmental pressures including sea level rise, increasing population, and changes in flows and nutrients from its upland catchment. With changing climate and socioeconomics there is a need to assess how the Mekong catchment will be affected in terms of the delivery of water and nutrients into the delta system. Here we apply the Integrated Catchment model (INCA) to the whole Mekong River Basin to simulate flow and water quality, including nitrate, ammonia, total phosphorus and soluble reactive phosphorus.

Impact of increased atmospheric moisture on the precipitation depth caused by Hurricane Ivan (2004) over a target area.

Sci Total Environ 2019 Apr 1;672:916-926. Epub 2019 Apr 1.

University of California, Davis, 1 Shields Ave, Davis, CA 95616, United States of America.

In this article, numerical experiments are performed to investigate the effects of increasing atmospheric moisture on the precipitation depth (PD) produced by Hurricane Ivan (2004) over a target area, chosen as the drainage basin of the city of Asheville, NC. Atmospheric moisture was increased indirectly by increasing the sea surface temperature (SST) in the simulation initial conditions, and by letting the regional atmospheric model adjust the atmospheric fields to the SST perturbation. The SST was increased in two ways: 1) using spatially constant increments and 2) using a climate change perturbation field obtained from a climate projection. Read More

Quantification of Leishmania Parasites in Murine Models of Visceral Infection.

Methods Mol Biol 2019 ;1971:289-301

i3S-Instituto de Investigação e Inovação em Saúde, Universidade do Porto, Porto, Portugal.

Visceral leishmaniasis (VL) is mainly caused by Leishmania donovani (India and East Africa), and Leishmania infantum (Mediterranean Basin and South America) infections. Although murine models of visceral infection lack the clinicopathological aspects of VL in humans, they have been proven useful at advancing our knowledge in the Leishmania field. Indeed, these models have been used not only to better understand the pathophysiology of the infection but also in drug and vaccine development. Read More

NO removal efficiency in field denitrification beds: key controlling factors and main implications.

Environ Microbiol Rep 2019 Apr 11. Epub 2019 Apr 11.

Institute for Applied Biosciences, Department of Applied Biology, Karlsruhe Institute of Technology (KIT), Karlsruhe, Germany.

Nitrate pollution is a growing environmental threat that affects both ground- and surface-water. The typically used technique for nitrate elimination in wastewater treatment plants cannot be applied for all water streams as it necessitates a highly developed technical infrastructure. Field denitrification beds comprise one strategy to treat surface water containing high nitrate loads, which typically is due to the increasing agricultural land use. Read More

Spatial variability of nitrate and ammonium in Pleistocene aquifer of central Yangtze River Basin.

Ground Water 2019 Apr 12. Epub 2019 Apr 12.

School of Environmental Studies, China University of Geosciences, Wuhan, 430074, China.

It becomes increasingly important and challenging for nitrogen pollution prevention to identify key controls for spatial variability of nitrogen in groundwater that could be affected by multiple factors, including anthropogenic input, groundwater flow and local geochemistry. This study characterized spatial variability of both nitrate and ammonium in the Pleistocene aquifer of central Yangtze River Basin and assessed the effect of various factors in controlling nitrate and ammonium levels based on multiple statistical approaches (correlation, geostatistics, multiple liner regression). The results indicate that nitrate is mostly influenced by Cl that represents anthropogenic input, while Eh representing local redox state is a secondary variable influencing nitrate concentrations.

Patterns of genetic differentiation in Colorado potato beetle correlate with contemporary, not historic, potato land cover.

Evol Appl 2019 Apr 12;12(4):804-814. Epub 2019 Jan 12.

Department of Entomology University of Wisconsin-Madison Madison Wisconsin.

Changing landscape heterogeneity can influence connectivity and alter genetic variation in local populations, but there can be a lag between ecological change and evolutionary responses. Temporal lag effects might be acute in agroecosystems, where land cover has changed substantially in the last two centuries. Here, we evaluate how patterns of an insect pest's genetic differentiation are related to past and present agricultural land cover change over a 150-year period. Read More

Geochemical behaviors of antimony in mining-affected water environment (Southwest China).

Environ Geochem Health 2019 Apr 10. Epub 2019 Apr 10.

College of Resource and Environmental Engineering, Guizhou University, Guiyang, 550025, Guizhou, China.

Antimony (Sb) is a harmful element, and Sb pollution is one of the typical environmental issues in China, meaning that understanding of the geochemical behaviors of Sb is the key to control the fate of environmental Sb pollution. Sb tends to migrate in soluble form in the water-sediment system, but the fate of dissolved Sb is poorly known. Duliujiang river basin, located in southwest China, provided us with a natural aqueous environment to study the transport of Sb because of its unique geological and geographical characteristics.
