Environmental variation across latitudinal gradients has led to consistent differences in vertebrate life histories [1]. This is especially well studied in birds where tropical birds produce smaller clutches of offspring [2] and have lower basal metabolic rates [3,4], but live longer [5,6] than ...
Pheno- types controlled by few, large-effect loci typically show predictable genetic paths of evolution, such as melanic colouration in mammals, fish, and birds22–25, perhaps due to selective constraints on genetic pathways21,26,27. Organisms adapting to complex environmental chal- lenges that ...
. Such general tropical-temperate differences seem to have promoted a slow pace of life in the tropics with reduced fecundity and increased survival [33,47], which for birds has been robustly established. For example, tropical birds, independent of biome, lay smaller clutches [48] and have ...
5. Birds 5.1. Non-passerines Non-passerines are typically larger than most passerines and even the small species tend to have relatively large gapes and can swallow large fruits for their body sizes (Corlett, 1998). With a few exceptions, such as the Asian koel (Eudynamys scolopaceus), mos...

No matter where you visit in the park, you’re bound to come across birds you haven’t seen before but those who are wanting the best birding opportunities possible should head to Yellow Water Billabong. Getting out on the water with Yellow Water Cruises is a popular choice for many, ...
Tiny, fat fluffly birds, pecking away at the trees and looking for a tasty morsels to sustain them. Whichever creature lost its feather, I hope it is thriving, and the loss of that single gorgeous bit of its plume simply reflected a change in the seasons rather than an encounter with ...
1836 is used as a major example. The content of this paper is mostly addressed to non-specialists whose research embraces scorpions in several fields such as venom toxins and public health. Although efforts have been made in the last 20 years to create better links between ‘true scorpion expe...
