The relative importance of regional and local factors in shaping zooplankton diversity in high-altitude tropical shallow lakes

Journal of Freshwater Ecology, 2020
In Brazil, although, high-altitude shallow lakes comprise large parts of conservation units and are considered highly important environments for biodiversity studies, little is known about the factors that regulate the zooplankton community.

Plant clonal integration mediates the horizontal redistribution of soil resources, benefiting neighbouring plants

Frontiers in Plant Science, 2016
Resources such as water taken up by plants can be released into soils through hydraulic redistribution and can also be translocated by clonal integration within a plant clonal network.

Pesticides, Preference Heterogeneity and Environmental Taxes [PDF]

, 2007
In this paper we present results from two Choice experiments (CE) designed to take account of the different negative externalities associated with pesticide use in agricultural production. For cereals production the most likely impact of pesticide use is

Genetic analysis of environmental variation [PDF]

, 2010
Environmental variation (V-E) in a quantitative trait - variation in phenotype that cannot be explained by genetic variation or identifiable genetic differences - can be regarded as being under some degree of genetic control. Such variation may be either

Effects of Habitat Heterogeneity and Topographic Variation on Insect Pest Risks in Alpine Regions

Land, 2023
Insect pests pose a significant threat to alpine ecosystems, especially under rapid environmental change conditions. Therefore, it is necessary to explore the effects of environmental factors on insect pest risks and provide methods for pest management ...

Dispersal Modifies the Diversity and Composition of Active Bacterial Communities in Response to a Salinity Disturbance

Frontiers in Microbiology, 2018
Dispersal can influence the response of bacterial communities to environmental changes and disturbances. However, the extent to which dispersal contributes to the community response in dependence of the character and strength of the disturbance remains ...

Structure of molluscan assemblages in sheltered intertidal unconsolidated environments

Brazilian Archives of Biology and Technology, 2005
The molluscan macrofauna from 13 oceanic sheltered intertidal unconsolidated environments and its relationship with abiotic factors were studied in order to establish the degree of species richness and to understand the role environment plays in ...

Plant architecture and vegetation structure: Two ways for insect herbivores to escape parasitism

European Journal of Entomology, 2008
Interactions between herbivorous insects and their parasitoids occur in highly structured and complex environments. Habitat structure can be an important factor affecting ecological interactions between different trophic levels.

Habitat associations of woody plant species in evergreen–deciduous broadleaf karst forests in southwest China

Frontiers in Ecology and Evolution, 2023
The effects of habitat filtering on community assembly have been extensively researched, and topography has been identified as a critical factor influencing the spatial distribution of trees. In this study, a 25-ha plot was established in karst evergreen–
