Assis, Leandro C.S., Brigandt, Ingo
Taxa and homologues can in our view be construed both as kinds and as individuals. However, the conceptualization of taxa as natural kinds in the sense of homeostatic property cluster kinds has been criticized by some systematists, as it seems that even such kinds cannot evolve due to their being...

The ability of farmers to adapt to changing rural environments in developing countries is an important determinant of welfare. However, farmers' adaptation may be constrained by their adaptive capacity because economic resources, information, and institutions are often weak or missing in these...

Independent evolution of leaf and root traits within and among temperate grassland plant communities
Download2011-01-01
In this study, we used data from temperate grassland plant communities in Alberta, Canada to test two longstanding hypotheses in ecology: 1) that there has been correlated evolution of the leaves and roots of plants due to selection for an integrated whole-plant resource uptake strategy, and 2)...

DownloadFall 2013
The Latino population in Canada has been increasing during the past decade accounting for 11% of newcomers in 2011. One of the core values in Latino culture is familism, the family is the main source of support and has an important role in childrearing. This qualitative study focuses on the...

Fall 2014
With well over 3,400 described species, snakes undoubtedly represent one of the most successful groups of reptiles. Much has been written about their ecology, behavior, anatomy, relationships and evolution. However, despite the debate about the origin of this taxonomic group dating back to the...

Fall 2018
A full understanding of the evolution of novel forms requires inference about their origins through the study of variation in extant taxa and clues from the fossil record. However, the origins of morphological diversity in many groups are obscured by the scarcity of transitional fossils or...

Osteology, Taxonomy, Phylogeny, and Body Shape Changes of Eocene Catostomid and Problematic Catostomid Fishes
DownloadFall 2016
Extant catostomid fishes occupy diverse aquatic ecosystems and niches in North America (NA). Less than 3% of catostomid taxonomic richness, or two species, are found outside of NA in Asia. Such adjunct and unbalanced distribution pattern has been established since the late Oligocene, when...

Fall 2009
When European children’s literature is adapted to North American film, parts of the stories are removed and changed in the hopes of producing something that will be considered acceptable in the target culture. Much of what is educational and cultural in the stories to begin with is removed...

Palaeoenvironment and palaeoecology of three Cretaceous snakes: Pachyophis, Pachyrhachis, and Dinilysia
Download2001
Caldwell, M. W., Albino, A. M.
The palaeoecology of three Late Cretaceous snakes is evaluated. Pachyophis woodwardi Nopcsa, 1923 and Pachyrhachis problematicus Haas, 1979, are Cenomanian in age and are found in carbonate rocks deposited in marine inter-reef basin environments of the European and African Tethys Sea. Dinilysia...
