Excerpt from Supplementary Appendix to Travels Amongst the Great Andes of the Equator
We accordingly pushed rapidly across the lower country both in going to and returning from the interior 51 and only acquired, whilst passing through it, such objects as came readily to hand. In respect to the interior, it should be noted (1) that the exigencies of travel often caused us to traverse considerable stretches of country without attempting to collect at all 5 (2) that, at such places as we stopped at, our researches never even approached an exhaustive character and (3) that the more minute species were rejected, owing to the known dith culty of inducing specialists to undertake their examination. Bearing these various points in mind, it appears to me improbable that in the interior (say, in the areas more elevated than 8000 feet) we obtained as much as one-tenth of the number of species which might have been collected by a person who could have given his whole time and atten tion to zoological research.

Paperback. Condizione: New. Print on Demand. This book presents the results of a journey through the great Andes of the Equator, which are mountains in the Andes with a high equatorial location. The author's aim was to collect and document as many species as possible from the highest zones, with a particular focus on Coleoptera, though they also collected many other types of insect and arachnid species. Over a third of the insects collected during this journey were previously unrecorded, and 14 new species of Coleoptera were identified. Many of the species found in the highest zones were found to be mountain representatives of species found in lower-lying areas, though some were found to be found in both temperate and high equatorial climates. The author notes that despite the presence of very similar species in high altitude and temperate regions, there was little evidence of migration along the Andes. Instead, species appear to have reached their current habitats through a combination of factors including altitude and climate, and the occasional breach of continuity of the land at the Isthmus of Panama. An additional theory proposed by the author is that the Andes may have been lower in the tropical zone during the Glacial epoch, creating different climate conditions that could have allowed tropical species to occupy a larger area.
