The application of 'least-cost' modelling as a functional landscape model (2003, unknown): “Recently, some studies used ‘least-cost’ modelling as an approach to incorporate detailed geographical information as well as behavioural aspects in a measure for connectivity (e.g. Walker and Craighead, 1997; Villalba et al., 1998; Halpin and Bunn, 2000; Ferreras, 2001; Graham, 2001; Michels et al.”
Vertebrate responses to fruit production in Amazonian flooded and unflooded forests (2007, background): “In the case of toucans, Graham (2001) noted that fruit abundance influenced toucan movements in Mexico when habitat connectivity was high.”
Large frugivorous birds facilitate functional connectivity of fragmented landscapes (2014, background): “Several studies demonstrate that large fruit-eating bird species such as hornbills in South-East Asia and Africa, and toucans in the Neotropics are able to fly between forest patches of fragmented landscapes and have the potential to act as long-distance seed dispersers (Kemp 1995; Powell & Bjork 19”
Does matrix resistance influence Red squirrel (Sciurus vulgaris L. 1758) distribution in an urban landscape? (2003, methodology): “Thanks to the new possibilities offered by GISsystems, landscape complexity can be included in the isolation measure when modelling dispersal Schippers et al. 1996; Tischendorf 1997; Halpin and Bunn 2000; Ferreras 2001; Graham 2001; Chardon et al. 2003 .”
Impact of landscape composition and configuration on forest specialist and generalist bird species in the fragmented Lacandona rainforest, Mexico (2015, background): “Nevertheless, because habitat generalist birds use resources not only from old-growth forests, but from other land covers in the matrix (Graham, 2001; Lindell et al., 2004), our findings indicate that their a-diversity can be negatively related to landscape forest cover, most probably because the in”
Cost distance modelling of landscape connectivity and gap‐crossing ability using radio‐tracking data (2010, background): “…based on expert judgement (Beier et al. 2008), based on proxy data such as the time spent in different habitat types by dispersing animals (e.g. Graham 2001) or by assuming that dispersal habitat is similar to breeding or foraging habitat (Chetkiewicz, Cassady St. Clair & Boyce 2006; e.g.…”
Can agroforest woodlots work as stepping stones for birds in the Atlantic forest region? (2008, background): “Because these elements can determine the probability of colonization between patches ( Fischer and Lindenmayer 2002b; Baum et al. 2004), it is expected that they can also have a larger-scale inXuence, as on the total diversity of a landscape.”
Estimating landscape resistance to movement: a review (2012, methodology): “None of these cases involved optimizing the HSF based on the home range data; in two of these cases they compared the composition of the home ranges to that of the study area in order to assign a habitat preference index to each environmental condition and then assigned resistance as the inverse of ”
Frequent bird movements across a highly fragmented landscape: the role of species traits and forest matrix (2013, background): “Food resource availability has been shown to strongly shape bird movements across heterogeneous landscapes (Zanette et al., 2000; Graham, 2001; Kennedy et al., 2010).”
Placing linkages among fragmented habitats: do least‐cost models reflect how animals use landscapes? (2011, background): “…solely to predict occupancy, model species distributions (e.g. Verbeylen et al. 2003; Magle, Theobald & Crooks 2009), explain gene flow (e.g. Vignieri 2005) or predict how landscape changes might affect focal species (e.g. Graham 2001) if they did not explicitly aim to design or evaluate linkages.”
Scattered trees are keystone structures – Implications for conservation (2006, background): “…in African savannas (N. Van Rooyen, unpublished data, cited in Jeltsch et al., 1996), Central American farming landscapes (Harvey and Haber, 1999; Graham, 2001), dehesas (Pulido et al., 2001), British wood-pastures (Kirby et al., 1995), and temperate Australian grazing areas (Spooner et al.,…”
Forks in the Road: Choices in Procedures for Designing Wildland Linkages (2008, methodology): “Graham (2001) used data on daily movements of Keel-billed Toucans (Ramphastos sulfuratus) to assign resistance scores to 3 coarse land-cover classes.”
The role of remnant trees in seed dispersal through the matrix: Being alone is not always so sad (2009, background): “This difference probably resulted from the reluctance (although not complete avoidance) of frugivorous birds to exploit fruit resources in the open matrix (Price et al., 1999; Graham, 2001 ).”
