        Short-term effects of habitat fragmentation on the abundance and species richness of beetles in experimental alfalfa micro-landscapes 

        GREZ,AUDREY A.; ZAVIEZO,TANIA; REYES,SUSANA (Sociedad de Biología de Chile, 2004)

        Effects of habitat loss and fragmentation on the abundance and species richness of aphidophagous beetles and aphids in experimental alfalfa landscapes 

        Grez Villarroel, Audrey; Zaviezo, Tania; Díaz, Sandra; Camousseigt, Bernardino; Cortés, Galaxia (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 ...

        Short-term effects of habitat fragmentation on the abundance and species richness of beetles in experimental alfalfa microlandscapes 

        Grez Villarroel, Audrey; Zaviezo, Tania; Reyes, Susana (SOCIEDAD BIOLOGIA CHILE, 2004-09)
        Habitat loss and fragmentation are considered as the main causes of biodiversity depression. Habitat loss implies a reduction of suitable habitat for organisms, and habitat fragmentation is a change in the spatial configuration ...

        Mechanisms affecting population density in fragmented habitat 

        Tischendorf, Lutz; Grez Villarroel, Audrey; Zaviezo, Tania; Fahrig, Lenore (RESILIENCE ALLIANCE, 2005-06)
        We conducted a factorial simulation experiment to analyze the relative importance of movement pattern, boundary-crossing probability, and mortality in habitat and matrix on population density, and its dependency on habitat ...

        Effects of habitat loss, habitat fragmentation, and isolation on the density, species richness, and distribution of ladybeetles in manipulated alfalfa landscapes 

        Zaviezo, Tania; Grez Villarroel, Audrey; Estades Marfán, Cristián; Pérez, Astrid (BLACKWELL, 2006-12)
        1. Habitat loss and fragmentation are the main causes of changes in the distribution and abundance of organisms, and are usually considered to negatively affect the abundance and species richness of organisms in a landscape. ...

        Are some life-history strategies more vulnerable to the genetic consequences of habitat fragmentation? A case study using South Australian Caladenia R. Br. (Orchidaceae) speciesAre some life-history strategies more vulnerable to the genetic consequences of habitat fragmentation? A case study using South Australian Caladenia R. Br. (Orchidaceae) species 

        Farrington, Lachlan; Facelli, José; Donnellan, Stephen; Austin, Andy

        Responses of Chilean forest birds to anthropogenic habitat fragmentation across spatial scales 

        Vergara, Pablo M.; Armesto, Juan J. (2009)
        Although it is recognized that anthropogenic forest fragmentation affects habitat use by organisms across multiple spatial scales, there is uncertainty about these effects. We used a hierarchical sampling design spanning ...

        The use of native vegetation as a proxy for habitat may overestimate habitat availability in fragmented landscapes 

        Universidade Federal do Rio de Janeiro (UFRJ); Universidade Estadual Paulista (UNESP); Universidade do Estado do Rio de Janeiro (UERJ); Int Inst Sustainabil (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 ...

        Distribution and habitat suitability index model for the Andean catfish Astroblepus ubidiai (Pisces: Siluriformes) in EcuadorDistribution and habitat suitability index model for the Andean catfish Astroblepus ubidiai (Pisces: Siluriformes) in Ecuador 

        Velez Espino, Luis A.

        Effects of habitat fragmentation on seed quality of Lapageria rosea Efecto de la fragmentación del hábitat sobre la calidad de las semillas en Lapageria rosea 

        Henríquez, Carolina A. (2004)
        Habitat fragmentation is commonly associated to a reduction in plant fitness, because the reduction in the number of seeds produced. However habitat fragmentation might also affect plant fitness through a reduction in the ...
