Outcomes of competitive interactions after a natural increment of resources: the assemblage of aphid-tending ants in northern Patagonia
(Springer, 2015-05)
Ant-aphid relationships provide excellent opportunities to study how changes in resource availability may affect the outcome of competitive interactions. Variations in soil fertility may affect host plant quality, with ...
The potential for indirect effects between co-flowering plants via shared pollinators depends on resource abundance, accessibility and relatedness
(Wiley, 2014-11)
Co-flowering plant species commonly share flower visitors, and thus have the potential to influence each other's pollination. In this study we analysed 750 quantitative plant–pollinator networks from 28 studies representing ...
Medium-density particleboards from rice husks and soybean protein concentrate
(John Wiley & Sons Inc, 2007-10)
Rice husks are a valuable agricultural residue produced worldwide with potential applications as a wood substitute in particleboard manufacturing. In this work, the feasibility of producing medium-density particleboards ...
Characterization of high density polyethylene (HDPE) reinforced with banana peel fibers
(2013-05-01)
Lignocellulosic fibers from banana peels were washed with water in order to increase their compatibility with a polymeric matrix, and their properties were compared with unwashed fibers. Washed banana fibers were mixed ...

Ecological correlates of group-size variation in a resource-defense ungulate, the sedentary guanaco
(Public Library of Science, 2014-02-19)
For large herbivores, predation-risk, habitat structure and population density are often reported as major determinants of group size variation within and between species. However, whether the underlying causes of these ...
Density and Spatial Distribution of Buffy-tufted-ear Marmosets (Callithrix aurita) in a Continuous Atlantic Forest
(Springer, 2011-08-01)
The continued degradation of forest habitats and isolation of fragmented populations means that the conservation of endemic marmosets in the Brazilian Atlantic forest depends on human interventions including legal protection. ...
Crecimiento del guapote lagunero (Cichlasoma dovii) en regimen de cultivo intenso en estanques y su dependencia de la densidad
(Universidad Nacional (Costa Rica), 1996)
Se determinan las características de crecimiento del guapote lagunero, Cichlasoma dovii, en régimen de cultivo intensivo en estanques de tierra y a dos densidades diferentes (1,4 y 2,8 peces /m2). El crecimiento y la ...
Land equivalent ratio in the intercropping of cucumber with lettuce as a function of cucumber population density
(2020-03-01)
Lettuce and cucumber are two important vegetables cultivated in greenhouses. Intercropping can increase the yield without increasing the demands for inputs. A more efficient use of resources in production systems can reduce ...
