“…For example, a study in the Amazon region concluded that island size is the most important determinant of species richness, yet they found no such relationship if based on islands that were below 10 ha (Benchimol & Peres, ). In our study site, the Thousand Island Lake, both amphibians and snakes have been found to have a clear threshold at 100 ha, below which no relation between fragment size and species richness was apparent (Wang, Wang, Wu, Chen, & Xu, ; Wang et al., ), which is consistent with our findings that both small and large mammal species richness do not respond to island sizes below 100 ha.…”

“…At present, 88.5% of the island area is covered by secondary forest which is dominated by Masson pine ( Pinus massoniana ) under which broad‐leaved trees and shrubs grow (Hu, Feeley, Wu, Xu, & Yu, ). This island system has been monitored for birds, mammals, reptiles and plants since 2006 to study the effects of fragmentation on these organisms (Si, Baselga, Leprieur, Song, & Ding, ; Wang, Bao, Yu, Xu, & Ding, ; Wang et al., ; Wilson et al., ; Yu et al., ), and thus provides an ideal platform for our study.…”

Aim Small, old‐growth forest fragments generally have more small‐seeded plants than large patches, due to the disappearance of large seed dispersing vertebrates. This pattern may differ for secondary forest fragments where differential migration ability rather than persistence of seed dispersers may be driving plant community assembly. In this study, we investigated the effect of habitat fragmentation on seed dispersers and plant community structure in regenerating forests. Location The Thousand Island Lake, China. Taxon Plants, birds and mammals. Methods We compiled diversity and abundance data for birds and mammals on islands in the Thousand Island Lake, China. We also surveyed the secondary plant communities and measured seed dispersal traits. Results Community‐weighted mean seed size of woody plants decreased with island size. This pattern was related to compositional difference of the dispersers. We found that mammal diversity and abundance was only weakly or not related to island size; whereas bird diversity and abundance increased strongly with island size. Density of bird‐dispersed plants was significantly positively related with island size. Since birds tend to disperse smaller seeds than mammals, the trend in seed size may have been a consequence of the shift in relative abundance of the two disperser guilds. Main Conclusions Differential responses of seed dispersers to habitat fragmentation may lead to pervasive shifts in the plant community structure of regenerating forest fragments. Our study highlights the importance of keeping large continuous forests in order to retain mammals and their dispersal capabilities.

“…Hanski et al (2013) [58] predicted such a decline while demonstrating that SARs that only account for area effects tend to overestimate species richness in fragmented landscapes if fragments are highly isolated, and they proposed an extension of the power function SAR that downsizes species richness in small fragments. In turn, a number of empirical studies reported a small island effect [12] where species density in very small islands or habitat patches increased [59–60]. Our results do not support either prediction.…”

Contrasting Patterns of Species Richness and Functional Diversity in Bird Communities of East African Cloud Forest Fragments

et al. 2016

Rapid fragmentation and degradation of large undisturbed habitats constitute major threats to biodiversity. Several studies have shown that populations in small and highly isolated habitat patches are prone to strong environmental and demographic stochasticity and increased risk of extinction. Based on community assembly theory, we predict recent rapid forest fragmentation to cause a decline in species and functional guild richness of forest birds combined with a high species turnover among habitat patches, and well defined dominance structures, if competition is the major driver of community assembly. To test these predictions, we analysed species co-occurrence, nestedness, and competitive strength to infer effects of interspecific competition, habitat structure, and species′ traits on the assembly of bird species communities from 12 cloud forest fragments in southern Kenya. Our results do not point to a single ecological driver of variation in species composition. Interspecific competition does not appear to be a major driver of species segregation in small forest patches, while its relative importance appears to be higher in larger ones, which may be indicative for a generic shift from competition-dominated to colonisation-driven community structure with decreasing fragment size. Functional trait diversity was independent of fragment size after controlling for species richness. As fragmentation effects vary among feeding guilds and habitat generalists, in particular, tend to decline in low quality forest patches, we plead for taking species ecology fully into account when predicting tropical community responses to habitat change.

“…The average annual temperature is 17.0°C, ranging from −7.6°C in January to 41.8°C in July. Annual precipitation in the region is 1430 mm, with an average of 155 days of precipitation per year (Wang et al, 2015). As land-bridge islands, the faunas of the archipelago and mainland have the same origin (Wang and Feng, 2009;Wang et al, 2010).…”
