Problems with the application of cladistics to forest fragmentation studies
(Wiley Blackwell Publishing, Inc, 2007-12)
Recently, Pellens et al. (2005) applied standard parsimony methods to the analysis of species communities in forest fragments. Their proposal consists of assembling a data matrix of species presence/absence for each fragment ...
Variations in tree community composition and structure in a fragment of tropical semideciduous forest in southeastern Brazil related to different human disturbance histories
(Elsevier B.V., 2004-08-23)
In an area of tropical seasonal semideciduous forest, the soil characteristics, floristic composition, physiognomic structure, and the distribution of three regeneration and three dispersal guilds were studied for four ...
A quantitative analysis of forest fragmentation in Los Tuxtlas, southeast Mexico: patterns and implications for conservation
(Sociedad de Biología de Chile, 2005)
Frugivory, Post-feeding Flights of Frugivorous Birds and the Movement of Seeds in a Brazilian Fragmented Landscape
(Wiley-Blackwell, 2011-05-01)
Habitat fragmentation can break down the movement processes of frugivorous animals, thus influencing the relationship between plants and their seed dispersers by altering the number and identity of seed dispersers, and ...

Experimental assessment of Heliconia acuminata growth in a fragmented Amazonian landscape
(Blackwell Publishing, 2002-08-01)
1 Fragmentation severely alters physical conditions in forest understories, but few studies have connected these changes to demographic impacts on forest species using detailed experimental examination at the individual ...
Denied density-dependent seedling recruitment in a fragmented forest does not decrease seedling diversity
(2011)
Negative density-dependent relationships in plant communities are currently claimed as an important mechanism for the maintenance of plant diversity. However, anthropogenic perturbations such as forest fragmentation might ...
Composition, species richness and abundance of nocturnal folivorous insects associated with Aristotelia chilensis (maqui) in the fragmented Maulino forest Composición, riqueza de especies y abundancia de insectos defoliadores de actividad nocturna asociad
(2008)
At the Maulino forest, herbivory upon Aristotelia chilensis (maqui) is negatively affected by forest fragmentation, being higher in the continuous forest than in the small remnant fragments, particularly at the beginning ...
Spatial dynamics of atlantic forest fragments in a river basin
(2020-01-01)
Considering the intrinsic relationship between vegetation and conservation of water resources, we evaluated the natural vegetation of an Atlantic Forest fragment through landscape metrics and spectral vegetation indices, ...
