| movement control strategies during jumping in a lizard (anolis valencienni). | whereas maximal performance is subjected to specific control criteria, sub-maximal movements theoretically allow for an infinite number of control strategies. yet sub-maximal movements are predominant in the locomotor repertoire of most organisms and often little understood. previous data on sub-maximal vertical jumping in humans has suggested that a movement effectiveness criterion might best explain the observed control strategy employed. here we test the generality of this criterion in jumpin ... | 2006 | 16061237 |
| molecular phylogenetic perspective on evolution of lizards of the anolis grahami series. | we report the results of phylogenetic analyses of 1447 bases of mitochondrial dna sequence for 21 populations representing seven species of the anolis grahami series (a. conspersus, a. garmani, a. grahami, a. lineatopus, a. opalinus, a. reconditus, and a. valencienni), six of which occur on jamaica. these data include 705 characters that are phylogenetically informative according to parsimony. a parsimony analysis of these data combined with previously published allozymic data yields a single mo ... | 2002 | 11932945 |
| geometric morphometric analysis of the breast-shoulder apparatus of lizards: a test case using jamaican anoles (squamata: dactyloidae). | the breast-shoulder apparatus (bsa) is a structurally and kinematically complex region of lizards. compared with the pelvic region it has received little attention, even though its morphological variation is known to be extensive. this variability has seldom been the focus of functional explanation, possibly because the bsa has been difficult to explore as a composite entity. in this study we apply geometric morphometric techniques to the analysis of the bsa in an attempt to more fully understan ... | 2014 | 24482396 |
