Relationship Processes in Understudied Samples : Implications for Relationship Functioning and Sexuality in Romantic Relationships

Uhlich, Maximiliane ; Schoebi, Dominik (Dir.)

Thèse de doctorat : Université de Fribourg, 2020.

Relationship functioning can be investigated from different angles; next to investigating dyadic outcomes between couples we can also zoom into processes within subjects. Adopting a cultural lens adds another layer, as the cultural context influences norms around intimate relationships, and can be inspected using the framework of Bronfenbrenner´s (1977) ecological systems theory. In more...

Adapting spherical-harmonics-based geometric morphometrics (SPHARM) for 3D images containing large cavity openings using ambient occlusion: a study with hermit crab claw shape variability

Ege, Yannic C. ; Foth, Christian ; Baum, Daniel ; Wirkner, Christian S. ; Richter, Stefan

In: Zoomorphology, 2020, p. -

One of the advantages of mesh-based geometric morphometrics (GM) over landmark-based approaches, is that it affords the possibility of the precise examination of highly irregular shapes and complex topographic surfaces. In the case of spherical-harmonic-based GM, the main prerequisite is a completely closed mesh surface, which is often lacking, particularly when dealing with natural objects....

Modularity of the neck in birds (Aves)

Terray, Léa ; Plateau, Olivia ; Abourachid, Anick ; Böhmer, Christine ; Delapré, Arnaud ; la Bernardie, Xavier de ; Cornette, Raphaël

In: Evolutionary Biology, 2020, p. -

The neck connects the head and the trunk and is the key structure allowing all movements of the head. The neck morphology of birds is the most variable among living tetrapods, including significant differences in the number and shape of the cervical vertebrae. Despite these differences, according to the literature, three morphofunctional regions (i.e., modules) have been identified along the...

A new alligatoroid from the Eocene of Vietnam highlights an extinct Asian clade independent from extant Alligator sinensis

Massonne, Tobias ; Vasilyan, Davit ; Rabi, Márton ; Böhme, Madelaine

In: PeerJ, 2019, vol. 7, p. e7562

During systematic paleontological surveys in the Na Duong Basin in North Vietnam between 2009 and 2012, well-preserved fossilized cranial and postcranial remains belonging to at least 29 individuals of a middle to late Eocene (late Bartonian to Priabonian age (39–35 Ma)) alligatoroid were collected. Comparative anatomical study of the material warrants the diagnosis of a new taxon,...

A Bit of Sex Stabilizes Host+Parasite Dynamics

Flatt, Thomas ; Maire, Nicolas ; Doebeli, Michael

In: Journal of Theoretical Biology, 2001, vol. 212, no. 3, p. 345-354

To date, only a few studies have focused on the effects of sex on population dynamics. Previous models have typically found that sexual reproduction dampens population fluctuations. Although asexual and sexual reproduction are just the two endpoints along a continuum of varying rates of sex, previous work has ignored the effects of intermediate degrees of sex on population dynamics. Here we study...
