BODY CONDITION AND MATE CHOICE IN TETRAGNATHA ELONGATA (ARANEAE, TETRAGNATHIDAE)

The Complete Mitochondrial Genome of two Tetragnatha Spiders (Araneae: Tetragnathidae): Severe Truncation of tRNAs and Novel Gene Rearrangements in Araneae

Mitogenomes can provide information for phylogenetic analysis and evolutionary biology. The Araneae is one of the largest orders of Arachnida with great economic importance. In order to develop mitogenome data for this significant group, we determined the complete mitogenomes of two long jawed spiders Tetragnatha maxillosa and T. nitens and performed the comparative analysis with previously pub...

Ancient DNA Resolves the History of Tetragnatha (Araneae, Tetragnathidae) Spiders on Rapa Nui

Rapa Nui is one of the most remote islands in the world. As a young island, its biota is a consequence of both natural dispersals over the last ~1 million years and recent human introductions. It therefore provides an opportunity to study a unique community assemblage. Here, we extract DNA from museum-preserved and newly field-collected spiders from the genus Tetragnatha to explore their histor...

Mate choice

If you are interested in the diversity of life, you can not ignore the plethora of striking behaviors and morphologies that have been the handiwork of sexual selection. The peacock’s tail is one emblematic result, but a compendium would also include: the songs of birds, frogs, and crickets, the brilliant colors of fishes and corals, the complex odors of moths and mustelids, and the differences ...

Mate Choice and Learning

Mate Choice in Parasitized

Synopsis. A recent model by Hamilton and Zuk (1982) suggests that exaggerated sec? ondary sexual traits facilitate mate choice for genetic resistance to parasites. The model predicts that individuals discriminate against parasitized mates by scrutinizing traits indicative of parasite load. In the case of birds and their feather-feeding lice, for example, individuals might avoid parasitized mate...
