In a context of exponential growth, small evolutionary changes in early cohorts led to a substantial difference in population size on the longer term (Fig. 2b). Discussion As there is accumulating evidence that AFR has evolutionary potential across several modern human populations15,16, the role ...
Landscape connectivity, the extent to which a landscape facilitates the flow of ecological processes such as organism movement, has grown to become a central focus of applied ecology and conservation science. Several computational algorithms have been developed to understand and map connectivity, and man...
The evolutionary ecology of venomous catfishes, with a focus on members of the North American family Ictaluridae (Teleostei: Siluriformes).The venom glands of fishes represent a widespread, putatively adaptive antipredatory trait, which have received little attention relative to those of other venomous...
We build on a commonality between proposed organism-level mechanisms of microbialisation, namely that macrobe communities are expected to be more vulnerable to stressors than microbial communities [26,27], an observation both supported in general [28] and in the case of OA in particular [29]....
nov., were investigated using modern methods. Here we provide detailed morphological information of these four species based on observations of specimens in vivo and after silver staining (Table 1). In addition, their phylogenetic relationships inferred from SSU rDNA, ITS1-5.8S-ITS2 and LSU rDNA...
The Netherlands (NL) was selected as an example because it is a major biofuels exporter and one of the greatest contributors to the biofuel science and R&D expenditure in the EU [1]. The analysis presented does not intend to assess the biofuel strategies adopted by Netherlands, but only to ...
The article below, from July’s American Naturalist (one of the major journals in ecology and evolutionary biology) shows two things. First, it’s one of the more ludicrous examples of science policing I’ve seen. Second, it shows how the American Society of Naturalists, which pub...
splitting of a group of interbreeding populations into two reproductively isolated groups, has been a major focus of evo- lutionary biology (1). In the widespread process known as “allopatric speciation,” populations that become geographically isolated experience selective pressures and/or genetic ...
Brain tissue is metabolically expensive. Consequently, the evolution of humans’ large brains must have occurred via concomitant shifts in energy expenditure and intake. Proposed mechanisms include dietary shifts such as cooking. Importantly, though, any
Synanthropic behavior, i.e., the behavior of wild animals that benefit from a shared ecology with humans, has existed long before the sedentarization of Ho
