Abstract

In Ecuador, the presence of melanistic individuals of Southern Tamandua Tamandua tetradactyla Linnaeus (1758) has been recognized but there has not been a formal report written about it. Neither has there been one on the observations or the collected specimens in museums. We present six records of melanism in Tamandua tetradactyla from southern Ecuador and discuss other records in wildlife and from museum collections. Half of the records are recent photographic ones (2018), and the other three are museum specimens collected between 2009 and 2016. Our report of melanistic individuals suggests that dark coloration varieties are frequent mutations in the region. This report can be useful to promote conservation initiatives, based on the Southern Tamandua as a potential flagship-species.

Impacts of roads and linear clearings on tropical forests.

William F. Laurance, Miriam Goosem, Susan Laurance (2009)

Linear infrastructure such as roads, highways, power lines and gas lines are omnipresent features of human activity and are rapidly expanding in the tropics. Tropical species are especially vulnerable to such infrastructure because they include many ecological specialists that avoid even narrow (<30-m wide) clearings and forest edges, as well as other species that are susceptible to road kill, predation or hunting by humans near roads. In addition, roads have a major role in opening up forested tropical regions to destructive colonization and exploitation. Here, we synthesize existing research on the impacts of roads and other linear clearings on tropical rainforests, and assert that such impacts are often qualitatively and quantitatively different in tropical forests than in other ecosystems. We also highlight practical measures to reduce the negative impacts of roads and other linear infrastructure on tropical species.
