Elliptic Fourier analysis on the tympanic bullae in three Meriones species (Rodentia, Mammalia): its application in biosystematics

TL;DR: The results show that characters of the auditory meatus separate these three species from each other, and the shape of different parts of the bullae within each species is also shown to vary such as in two populations of M. persicus.

Abstract: . The size and shape of the auditory bullae are investigated across three species of Meriones, in order to determine the biosystematic value of bulla characteristics in species recognition. This study is based on outline (geometric morphometric) with elliptical Fourier and eigenshape analysis of tympanic bullae in: (a) the suprameatal triangle, (b) the mastoid, (c) the auditory meatus, and (d) the ventral view of bullae. The results show that characters of the auditory meatus separate these three species from each other. The shape of different parts of the bullae within each species is also shown to vary such as in two populations of M. persicus. The shape of organs is important in the interaction between the organism and its environment. Tympanic bullae variation is similar in the Geno population of M. persicus (Geno is located in south of Iran), and in M. libycus which lives in similar climates. The results of this analysis of tympanic bullae differ from the characters described by CORBET (1978).

Adaptive latitudinal trends in the mandible shape of Apodemus wood mice
Sabrina Renaud,Johan Michaux +1 more
- 01 Jan 2002
TL;DR: In this paper, the shape and size of the mandible of the European wood mouse (Apodemus sylvaticus) were investigated across the latitudinal range of the mouse in order to address the relative importance of genetic structure, insularity and geographical gradient in patterning morpho-logical variation.

Molecular systematics of gerbils and deomyines (Rodentia: Gerbillinae, Deomyinae) and a test of desert adaptation in the tympanic bulla
TL;DR: Support is found for the discordance between molecular and morphological phylogenies in gerbils being partly due to convergent adaptations to arid environments, primarily in the suite of traits associated with inflation of the tympanic bullae.

A phylogenetic test of adaptation to deserts and aridity in skull and dental morphology across rodents
TL;DR: Bullar hypertrophy is among the strongest patterns of convergent cranial desert adaptation in rodents and indicates that adaptation plays a similar role in shaping the evolution of this structure in different desert rodent clades.

Qualitative and Quantitative Analysis of Talons of Diurnal Bird of Prey
TL;DR: This work set out to find a tool that allows for the determination of toe (I-IV) and hindlimb (left or right) identity, and established qualitative and quantitative differences and similarities among talons lacking the keratin sheath in diurnal raptors.

Patterns of skull shape variation in Meriones persicus (Rodentia: Muridae) in relation to geoclimatical conditions
TL;DR: This study investigates skull variation in Persian jird, Meriones persicus in relation to the geoclimatical conditions across its distribution range through landmark-based geometric morphometric techniques and the Two-Block Partial Least-Squares method.

Elliptic Fourier shape analysis of fossil bivalves: some practical considerations
TL;DR: Elliptic Fourier shape analysis is a powerful, though underutilized, biometric tool that is particularly suited for the description of fossils lacking many homologous landmarks, such as several common bivalve groups as discussed by the authors.

The anatomy, physiology, functional significance and evolution of specialized hearing organs of gerbilline rodents
TL;DR: Middle and inner ear anatomy correlates with neurophysiological responses to a wide range of sound frequencies for species of the Gerbillinae representing generalized, intermediate, and specialized anatomical conditions.
Adaptive latitudinal trends in the mandible shape of Apodemus wood mice
Sabrina Renaud,Johan Michaux +1 more
TL;DR: The latitudinal gradient in mandible shape observed in the threespecies of wood mice is interpreted as an intraspecific adaptive response to gradualchanges in feeding behaviour and should be interpreted as a secondary process of shape differentiation.

Elliptic Fourier analysis of the form of genitalia in two Spodoptera species and their hybrids (Lepidoptera: Noctuidae)
TL;DR: The results suggest that morphological differences may be controlled by a polygenic system with maternal effect in F1 and parental dominance in backcross hybrids in S. latifascia and S. descoinsi, a closely related species of Noctuid moths.
