| 4 | Can incidental sighting data be used to elucidate habitat preferences and areas of suitable habitat for a cryptic species?显示文摘The involvement of communities in ecological studies has been shown to augment conservation efforts,especially for cryptic species.However,there is a lack of studies addressing the utility of incidental sighting records from community members in gaining knowledge on habitat preferences and distribution of suitable habitat for these organisms.This study compares preferences of the Lumholtz’s tree kangaroo(Dendrolagus lumholtzi;LTK),a cryptic rainforest folivore in northeastern Australia,for various habitat and climatic variables derived from data collected during scientific projects to those derived from incidental sighting records using ArcGIS and Maxent.Incidental sighting records suggest that the species uses a wider range of altitudes,annual rainfalls,annual mean temperatures and vegetation types than predicted by scientific studies.Incidental records also show that the species can persist in areas of lower rainfall during the wettest month and lower minimum temperature during the coldest month.Both data place the species within a comparable range of rainfalls during the driest month,maximum temperatures of the warmest month and soil types.When using identified preferences to assess the extent and distribution of suitable habitat,incidental records predicted more areas of suitable habitat than scientific records with an overlap of up to 91%between them.The present study proves that incidental sighting records can be a valuable part of the study of cryptic species and should be considered complementarily alongside scientific studies to obtain comprehensive ecological information of a species that can assist in its conservation. | Wesley R.HAUSER Sigrid R.HEISE-PAVLOV | 2017 | Integrative Zoology2017，12，3： | 0 |
