Genetic analysis of landscape connectivity in tree populations (2006, background): “Many studies have shown that anthropogenic disturbance results in a loss of vertebrate dispersal agents (e.g., Wright and Duber 2001), which may reduce the connectivity among fragments if it increases isolation (Table 1).”
Forest fragment size and microhabitat effects on palm seed predation (2006, background): “Most studies that have examined the effect of microhabitat on seed predation have not considered the influence of forest area and/or defaunation on this process (Smythe, 1986; Schupp, 1988a,b; Smythe, 1989; Forget and Milleron, 1991; Tellerı́a et al., 1991; Schupp and Fuentes, 1995; Cintra and Horna”
Predicting the Long‐Term Effects of Hunting on Plant Species Composition and Diversity in Tropical Forests (2007, background): “Wright and Duber (2001) found that hunting reduces rodent seed predation of the large-seeded palm Attalea butyraceae from over 90 percent to approximately 40 percent of seeds.”
Theory meets reality: How habitat fragmentation research has transcended island biogeographic theory (2008, background): “When hyperabundant, such omnivores can have important impacts on nesting birds (Crooks and Soulé, 1999; Schmidt, 2003), large-seeded plants (Wright and Duber, 2001), and other species (Dirzo and Miranda, 1991; Laurance, 1997).”
Seed survival and dispersal of an endemic Atlantic forest palm: the combined effects of defaunation and forest fragmentation (2006, background): “Old endocarps were not sampled (see, e.g., Wright et al ., 2000; Wright & Duber, 2001).”
Domestic dogs as an edge effect in the Brasília National Park, Brazil: interactions with native mammals (2009, background): “…tolerance of the responsive species (Lovejoy et al., 1986; Laurance, 1990, 1994); (3) indirect biological effects, involving changes in species interactions, such as predation, parasitism, competition and herbivory (Dirzo & Miranda, 1991; Wright & Duber, 2001; Asquith & MejiaChang, 2005).”
Biodiversity Regulation of Ecosystem Services (2005, background): “As the heavy poaching, the number of seeds dispersed decreases (e.g., Wright biomass from the dead trees decomposes, it is converted into greenhouse and Duber 2001; Wright et al. 2000).”
The myriad consequences of hunting for vertebrates and plants in tropical forests (2003, methodology): “Just two studies have directly examined the consequences of hunting for plant-vertebrate interactions in tropical forests (Wright et al. 2000; Wright & Duber 2001).”
Fruit Availability and Peccary Frugivory in an Isolated Atlantic Forest Fragment: Effects on Peccary Ranging Behavior and Habitat Use (2007, background): “Area reduction is generally accompanied by a loss of habitat diversity, which in turn affects fruit diversity (Wright & Duber 2001, Tabarelli et al. 2004).”
Differential Responses to Hunting in Two Sympatric Species of Brocket Deer (Mazama americana and M. nana) (2008, background): “…whole ecosystem, such as severe changes in the structure and composition of the forest, can also follow reductions in numbers of large ungulates (Wright & Duber 2001, Corlett 2007), although the long-term consequences of this phenomenon are still not clear (Wright et al. 2000, Wright 2003,…”
Differential Effects of Hunting on Pre‐Dispersal Seed Predation and Primary and Secondary Seed Removal of Two Neotropical Tree Species (2007, background): “The protected and hunted areas are in close proximity to each other and are both in lowland rain forests with similar species composition (Wright & Duber 2001).”
Size‐Related Differential Seed Predation in a Heavily Defaunated Neotropical Rain Forest (2007, background): “The possibility of compensatory seed predation by insects needs to be investigated, but available information suggests that in the absence of mammalian seed predators, insect seed predation cannot fully compensate for predation by mammals (Wright & Duber 2001).”
Testing predictions of the Janzen–Connell hypothesis: a meta-analysis of experimental evidence for distance- and density-dependent seed and seedling survival (2014, background): “In particular, studies have found that patterns of density and distance dependence can be altered when vertebrate seed disperser and seed predator populations are reduced due to poaching and other human disturbances (Wright & Duber 2001; Wyatt & Silman 2004).”
Biodiversity, species interactions and ecological networks in a fragmented world (2012, background): “In turn, important animal–plant interactions can be affected (Aizen and Feinsinger, 1994a,b; Cunningham, 2000; Fleury and Galetti, 2006; Galetti et al., 2006; Jordano and Schupp, 2000; Wright and Duber, 2001).”
EFFECTS OF SMALL RODENTS AND LARGE MAMMALS ON NEOTROPICAL SEEDS (2004, background): “While many different Neotropical mammalian species contribute to seed predation (Forget 1993, 1994, Asquith et al. 1997, 1999, Wright et al. 2000, Wright and Duber 2001), to date, few studies have quantified dif- ferences in how these groups of seed predators interact.”
