Phylogeny and Character Behavior in the Family Lemuridae

Test of the Optimal Body Size Model for Strepsirhines

“…1. The phylogeny of the strepsirhines in this study (Mayor et al, 2004;Wyner et al, 2000;Yoder, 1997Yoder, , 2003Yoder et al, 2000). strepsirhines, includes numerous regions of the genome, and supports many of the phylogenetic relationships reported from morphological studies.…”

“…strepsirhines, includes numerous regions of the genome, and supports many of the phylogenetic relationships reported from morphological studies. We supplemented the phylogeny with more recent genetic data (Delpero et al, 2001;Mayor et al, 2004;Poux and Douzery, 2004;Wyner et al, 2000;Yoder et al, 2000). Serial independence tests indicated significant phylogenetic autocorrelation for male body size (C = .442, p = .001) and female body size (C = .685, p = .001), but not for 2-dimensional home range size in males (C = .169, p = .197) and females (C = .201, p = .171).…”

Geometric Morphometric Investigation of Molar Shape Diversity in Modern Lemurs and Lorises

“…Modern strepsirrhines are incredibly diverse in their body size [between $30 g and 6840 g (0.3-6.84 kg)], ecological habitat, and dietary patterning (Fleagle, 1999). Whereas lemurs and lorises are generally considered the most basal of the extant primates, particular systematic issues continue to be debated in the literature (Crovella et al, 1993;Purvis, 1995;Yoder and Irwin, 1999;Wyner et al, 2000;Yoder et al, 2001;Pastorini et al, 2003;Roos et al, 2004;Karanth et al, 2005;Masters et al, 2005). Discussion also continues regarding the relationships between primates and non-primate outgroup taxa.…”

“…1. Summary of current phylogenetic hypotheses concerning the relationships between lemuriforms, lorisiforms, and outgroup nonprimate taxa (Tupaia) (Crovella et al, 1993;Purvis, 1995;Yoder and Irwin, 1999;Wyner et al, 2000;Yoder et al, 2001;Pastorini et al, 2003;Roos et al, 2004;Karanth et al, 2005;Masters et al, 2005Masters et al, , 2006.

Genetic Comparison of Two Populations of Hapalemur simus Inferred from D-Loop Mitochondrial DNA Sequences

“…Other procedures are detailed elsewhere [Andriaholinirina et al, 2002]. DNA extraction amplification and sequencing procedures are those previously described [Fausser et al, 2002], but with the following modifications: a double-stranded fragment of 481 bp corresponding to a part of the mitochondrial D-loop was generated with the primers D1p1.5 (5¢-GCACCCAAA-GCTGARRTTCTA-3¢) [Wyner et al, 2000] and D1p5 (5¢-CCATCGWGATGTCTTATTTA-AGRGGAA-3¢) [Baker et al, 1993]. Reactions were done in a Perkin Elmer Cetus DNA thermocycler 480 as follows: pre-denaturation (10 min at 94°C) and 35 cycles of denaturation (1 min at 94°C), annealing (1 min at 54°C), extension (90 s at 72°C), followed by a final extension step (10 min at 72°C).…”
