Long‐Term Effects of Forestry on Birds of the Eastern Canadian Boreal Forests: a Comparison with Fennoscandia

摘要: : Logging is considered the most important threat to species in boreal forests. In contrast eastern Canada, where forests remain largely untouched, Fennoscandia it possible assess cumulative, long-term effects of intensive forestry on wildlife. But harvesting stands rapidly changing Canadian forests, which represent an proportion world's We show that and Canada present striking similarities terms forest-age structure, natural-disturbance regime, structure bird assemblages, we provide assessment birds forest. used life-history traits from habitat, nesting site, geographical range calculate index sensitivity changes induced by modern for each region. Tropical migrants commonly found have are not factors relation caused forestry. Therefore, general belief tropical North America more sensitive landscape than those Europe may hold coniferous Canada. Nine Fennoscandian high levels sensitivity, at least eight similar concern. both regions, resident cavity nesters. Given between two northern expansion commercial likely result significant decline several species, as has occurred Fennoscandia. Resumen: La tala es considerada la amenaza mas importante para las especies de los bosques boreales. En contraste con el este donde boreales permanecen practicamente sin tocar, posible evaluar efectos acumulativos largo plazo actividad forestal intensiva sobre vida silvestre en Fennoscandia. Sin embargo, explotacion madera esta cambiando rapidamente canadienses, que representan una proporcion del mundo. Mostramos y tienen similitudes notables terminos estructura edades bosque, regimen perturbaciones comunidades aves, aportamos evaluacion a actividades forestales aves Utilizamos rasgos historia como sitio anidacion rango geografico calcular un indice sensibilidad cambios inducidos por modernas cada Los migrantes tropicales son comunes no factores relacion causados moderna. Por lo tanto, creencia generalizada mayor paisaje Norte comparacion Europa puede ser valida coniferas Canada. Nueve presentan altos niveles sensibilidad, mientras menos ochos interes similar. ambas regiones, mayoria sensitivas residentes anidan cavidades. Dadas importantes entre dos probable que, Fennoscandia, comerciales resulte declinacion significativa varias residentes.
