Plant recruitment bottlenecks in temperate forest fragments: seed limitation and insect herbivory

Abstract: Numerous studies have documented declines in plant diversity in response to habitat loss in fragmented landscapes. However, determining the mechanisms that lead to species loss is challenging using solely a correlative approach. Here we link correlative assessments of plant community composition with seed additions for a focal species to test the hypothesis that distributions of forests plants within a fragmented landscape are limited by seed dispersal. Woody plant species richness of fragments declined as fra… Show more

“…Lack of habitat continuity in the case of forest ecosystems can affect the occurrence of some trees, especially heavy-grain species that have constrained dispersal ranges and colonization abilities (McEuen and Curran 2006). However, we did not detect differences in the occurrence of heavy-grain oak among ownership categories (Table 1), which may indicate that the origin of private and state forests was in fact similar or had no effect on present stand characteristics.…”

“…However, these patches begin to exist independently from the moment of extraction. The intensity of various biotic and abiotic factors, such as climate parameters, expansion of alien species, seed dispersion, may differ in forest interiors and at its edges (Saunders et al 1991;Saunders et al 1999;McEuen and Curran 2006) and all this may induce patches varying in size to develop differently (e.g. Ries et al 2004).…”

“…These researchers reported a greater seedling mortality due to herbivorous mammals on the smaller islands than on the larger islands and in mainland Panama and attributed this diVerence to the absence of vertebrate predators on the small islands, where seedling survival increased sixfold when protected from the herbivores. In a hardwood North American forest, McEuen and Curran (2006) also found greater levels of herbivory in isolated fragments. However, in landscapes where small mammals have been decimated by habitat fragmentation, there is less herbivory in small fragments (Benítez-Malvido 1998;Dirzo 2001).…”

“…In forests, habitat loss and fragmentation increase isolation and physical and biotic edge eVects and, therefore, may alter tree regeneration and biotic interactions inside the fragments (Janzen 1983;Benítez-Malvido and Lemus-Albor 2005;McEuen and Curran 2006). The nature of the surrounding landscape (external matrix) often has the largest eVect on tree regeneration (Alverson et al 1988;Saunders et al 1991) because of the increased biotic and physical (Paton 1994;Curran et al 1999;Laurance 2000;Laurance et al 2002).…”

“…Lindera benzoin plants in the understory also have lower flower production and fruit set, and they experience significantly more herbivory in comparison to plants in edges and gaps (Niesenbaum 1992a(Niesenbaum , 1993. Herbivory also negatively affects seedling survival in the forest understory (McEuen and Curran 2006). Differences in herbivory between light environments may be explainable by lower nutritional quality of sun leaves to herbivores (Muth et al 2008) and by increased bird predation on herbivores in gaps and edges (Skoczylas et al 2007).…”
