Changes in Habitat Use at Rain Forest Edges Through Succession: A Case Study of Understory Birds in the Brazilian Amazon
Primary tropical rain forests are being rapidly perforated with new edges via roads, logging, and pastures, and vast areas of secondary forest accumulate following abandonment of agricultural lands.

Abandoned Land Age Class Edge Effect Forest Ecosystem Habitat Fragmentation Habitat Use Insectivore Neotropical Region Passerine Rainforest Secondary Forest Succession Understory Amazonia Brasil Aves Formicarius Colma Glyphorynchus Spirurus Xiphorhynchus Pardalotus Primary tropical rain forests are being rapidly perforated with new edges via roads, logging, and pastures, and vast areas of secondary forest accumulate following abandonment of agricultural lands. To determine how insectivorous Amazonian understory birds respond to edges between primary rain forest and three age classes of secondary forest, we radio-tracked two woodcreepers (Glyphorynchus spirurus, N = 17; Xiphorhynchus pardalotus, N = 18) and a terrestrial antthrush (Formicarius colma, N = 19). We modeled species-specific response to distance to forest edge (a continuous variable) based on observations at varying distances from the primary-secondary forest interface. All species avoided 8-14-yr-old secondary forest. Glyphorynchus spirurus and F. colma mostly remained within primary forest <100 m from the young edge. Young F. colma rarely penetrated >100 m into secondary forest 27-31 yr old. Young Formicarius colma and most G. spirurus showed a unimodal response to 8-14-yr-old secondary forest, with relative activity concentrated just inside primary forest. After land abandonment, G. spirurus was the first to recover to the point where there was no detectable edge response (after 11-14 yr), whereas X. pardalotus was intermediate (15-20 yr), and F. colma last (28-30 yr +). Given the relatively quick recovery by our woodcreeper species, new legislation on protection of secondary forests > 20-yr old in Brazil's Pará state may represent a new opportunity for conservation and management; however, secondary forest must mature to at least 30 yr before the full compliment of rain forest-dependent species can use secondary forest without adverse edge effects. © 2015 Association for Tropical Biology and Conservation Inc. 2020-06-15T21:42:55Z 2020-06-15T21:42:55Z 2015 Artigo https://repositorio.inpa.gov.br/handle/1/17448 10.1111/btp.12253 en Volume 47, Número 6, Pags. 723-732 Restrito Biotropica |

Primary tropical rain forests are being rapidly perforated with new edges via roads, logging, and pastures, and vast areas of secondary forest accumulate following abandonment of agricultural lands. To determine how insectivorous Amazonian understory birds respond to edges between primary rain forest and three age classes of secondary forest, we radio-tracked two woodcreepers (Glyphorynchus spirurus, N = 17; Xiphorhynchus pardalotus, N = 18) and a terrestrial antthrush (Formicarius colma, N = 19). We modeled species-specific response to distance to forest edge (a continuous variable) based on observations at varying distances from the primary-secondary forest interface. All species avoided 8-14-yr-old secondary forest. Glyphorynchus spirurus and F. colma mostly remained within primary forest <100 m from the young edge. Young F. colma rarely penetrated >100 m into secondary forest 27-31 yr old. Young Formicarius colma and most G. spirurus showed a unimodal response to 8-14-yr-old secondary forest, with relative activity concentrated just inside primary forest. After land abandonment, G. spirurus was the first to recover to the point where there was no detectable edge response (after 11-14 yr), whereas X. pardalotus was intermediate (15-20 yr), and F. colma last (28-30 yr +).
