Habitat heterogeneity drives bird species richness, nestedness and habitat selection by individual species in fluvial wetlands of the Paraná River, Argentina
(Wiley Blackwell Publishing, Inc, 2016-11)
We assessed the relationship between habitat heterogeneity and bird species richness and composition within wetlands of the floodplain of the Middle Paraná River, Argentina. Given the high habitat heterogeneity in these ...
The use of native vegetation as a proxy for habitat may overestimate habitat availability in fragmented landscapes
(Springer, 2016-05-01)
Native vegetation is often used as a proxy for habitat to estimate habitat availability in landscapes. This approach may lead to incorrect estimates of the impacts of habitat loss and fragmentation on species, which have ...
Effects of habitat loss and fragmentation on the abundance and species richness of aphidophagous beetles and aphids in experimental alfalfa landscapes
(Czech Academy of Sciences, 2008)
In agro-ecosystems, habitat loss and fragmentation may alter the assemblage of aphidophagous insects, such as foliarforaging (coccinellids) and ground-foraging predators (carabids), potentially affecting intraguild ...
Land use intensification differentially benefits alien over native predators in agricultural landscape mosaics
(2013)
Aim: Both anthropogenic habitat disturbance and the breadth of habitat use by alien species have been found to facilitate invasion into novel environments, and these factors have been hypothesized to be important within ...
Bromeliads as biodiversity amplifiers and habitat segregation of spider communities in a Neotropical rainforest
(Amer Arachnological Soc, 2010-01-01)
Although bromeliads can be important in the organization of invertebrate communities in Neotropical forests, few studies support this assumption. Bromeliads possess a three-dimensional architecture and rosette grouped ...
Bromeliads as biodiversity amplifiers and habitat segregation of spider communities in a Neotropical rainforest
(2010-08-01)
Although bromeliads can be important in the organization of invertebrate communities in Neotropical forests, few studies support this assumption. Bromeliads possess a three-dimensional architecture and rosette grouped ...
How population loss through habitat boundaries determines the dynamics of a predator-prey system
(Elsevier B.V., 2014-12-01)
The increased persistence of predator-prey systems when interactions are distributed through the space has been acknowledged by both empirical and theoretical studies. One salient feature of predator-prey interactions in ...
Tadpole community structure in lentic and lotic habitats: richness and diversity in the Atlantic Rainforest lowland
(British Herpetol Soc, 2017-07-01)
The analysis of species richness and community composition provides basic information to understand the structure of species assemblages. Here, we compared species richness and composition, compositional similarity and ...

Does the effect of aquatic plant types on invertebrate assemblages change across seasons in a subtropical wetland?¿El efecto de los tipos de plantas acuáticas sobre los ensambles de invertebrados cambia en las distintas estaciones en un humedal subtropical?
(Asoc Espan Limnol-mislata, 2017-05)
La complejidad del hábitat es uno de los factores fundamentales que determinan la distribución de los ensambles de invertebrados debido a que las diferentes arquitecturas y formas de crecimiento de las plantas acuáticas ...
