Spatial density‐dependent parasitism and specificity in the robber fly Mallophora ruficauda (Diptera: Asilidae)
(Wiley, 2010-02)The density‐dependence in parasitism by the robber fly Mallophora ruficauda (Diptera: Asilidae) on scarab beetle larvae (Coleoptera: Scarabaeidae) populations was studied in the present research. Mallophora ruficauda is a ... -
Spatial distribution of Mycobacterium bovis spoligotypes in cattle from the state of Minas Gerais, Brazil
(Springer, 2022-07)Genotyping methods have led to a better understanding of the epidemiology of Mycobacterium bovis (M. bovis) infection, and its transmission dynamics, as well as the possible phylogenetic relationships between Mycobacterium ... -
Spatial distribution of pesticides in surface water of the Estacas stream (Argentine Espinal region) associated with crop production
(Springer, 2023-01)The Espinal region (Entre Ríos, Argentina) has sufered land use changes caused by expansion of the agricultural frontier. This expansion has led to an increased use of pesticides. This study is aimed at better understanding ... -
Spatial distribution of soil carbon storage in desert shrubland ecosystems of northwest Mexico
(Elsevier, 2020-12)The scarce information about soil carbon (C) storage in water-stressed ecosystems limits our understanding on soil contribution to the C cycle in arid zones. This study, performed in arid NW México: (i) estimated soil ... -
Spatial distribution of volcanic ash deposits of 2011 Puyehue-Cordón Caulle eruption in Patagonia as measured by a perturbation in NDVI temporal dynamics
(2018-03)Volcanic ash fallout is a recurrent environmental disturbance in forests, arid and semi-arid rangelands of Patagonia, South America. The ash deposits over large areas are responsible for several impacts on ecological ... -
Spatial dynamics of a Sirex noctilio woodwasp population within a pine plantation in Patagonia, Argentina
(Wiley, 2007-12)The woodwasp Sirex noctilio F. (Hymenoptera: Siricidae) is probably the most important pest of pine tree plantations of the southern hemisphere. We studied the spatial arrangement of an endemic population of the woodwasp ... -
Spatial heterogeneity in species composition constrains plant community responses to herbivory and fertilisation
(Wiley, 2018-09)Environmental change can result in substantial shifts in community composition. The associated immigration and extinction events are likely constrained by the spatial distribution of species. Still, studies on environmental ... -
Spatial pattern of attacks of the invasive woodwasp Sirex noctilio, at landscape and Stand Scale
(2015-05-18)Invasive insect pests are responsible for important damage to native and plantation forests, when population outbreaks occur. Understanding the spatial pattern of attacks by forest pest populations is essential to improve ... -
Spatial pattern of Pindó Palm (Syagrus romanzoffiana) recruitment in Argentinian atlantic forest: the importance of tapir and effects of defaunation
(Wiley; Association of Tropical Biology and Conservation, 2014-11)Hunting pressure, fragmentation and deforestation have caused global declines in animal abundance, and the consequences for plant communities are poorly understood. Many large‐seeded plants, for instance, depend on large ... -
Spatial patterns of cultural ecosystem services provision in Southern Patagonia
(Springer, 2016-02)Context Although there is a need to develop a spatially explicit methodological approach that addresses the social importance of cultural ecosystem services for regional planning, few studies have analysed the spatial ... -
Spatial prediction of soil organic carbon stocks in Ghana using legacy data
(Elsevier, 2019-11)Soil organic carbon (SOC) is a major driver of the multiple functions of soils in the delivery of ecosystem services. While the spatial prediction and mapping of SOC stocks are of key importance for land managers to ... -
Spatial variability of nitrous oxide emissions from croplands and unmanaged natural ecosystems across a large environmental gradient
(Wiley, 2025-03)Atmospheric nitrous oxide (N2O) is a potent greenhouse gas, with long atmospheric residence time and a global warming potential 273 times higher than CO2. N2O emissions are mainly produced from soils and are influenced by ... -
Spatially variable hidrologic impact and biomass production tradeoffs associated with Eucaliptus ( E. Grandis) cultivation for biofuel production in Entre Ríos, Argentina
(Wiley, 2021-01-11)Climate change and energy security promote using renewable sources of energy such as biofuels. High woody biomass production achieved from short-rotation intensive plantations is a strategy that is increasing in many parts ... -
Spatial–temporal trends and economic losses associated with bovine abortifacients in central Argentina
(Springer, 2022-07-30)The aims of this work are, firstly, to provide the geolocalization of cases of bovine abortion with definitive diagnosis and, secondly, to estimate the economic losses due to the most frequent abortifacients diagnosed ... -
Spatio and temporal spread of Plum pox virus infecting European plum (Prunus domestica L. cv. D'agen) orchard in Mendoza, Argentina = Distribución espacial y temporal del Plum pox virus en un monte de ciruelo europeo (Prunus domestica L cv D'agen) de Mendoza, Argentina
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020)Sharka, caused by Plum pox virus (PPV), is considered one of the most serious viral diseases of stone fruits worldwide due to the great yield losses in orchards. In Rama Caída, Mendoza, a 5-year study (2007-2011) was ... -
Spatio-temporal dynamics of landscape use by the bumblebee Bombus pauloensis (Hymenoptera: Apidae) and its relationship with pollen provisioning
(Plos One, 2020-07)Understanding how bees use resources at a landscape scale is essential for developing meaningful management plans that sustain populations and the pollination services they provide. Bumblebees are important pollinators for ... -
