Extreme Behavioral Adjustments by an Orb‐Web Spider to Restricted Spaces
(2012)
Adaptive flexibility in response to environmental variation is often advantageous and occurs in many types of traits in many species. Although the basic designs of the orb webs of a given species are relatively uniform, ...
Vestiges of an orb-weaving ancestor? The “biogenetic law” and ontogenetic changes in the webs and building behavior of the black widow spider Latrodectus geometricus (Araneae Theridiidae)
(2008)
Young juveniles of L. geometricus fit the strong trend for “ontogeny to repeat phylogeny” previously documented in other web-building spiders; younger spiders were less likely to build the derived silk retreats that occur ...
La alometría estática de estructuras bajo selección sexual.
(2012-04-24)
El proyecto se diseñó para determinar la alometría del tamaño de las estructuras genitálicas y otras no-genitálicas en varias especies de Coleoptera. El informe es una lista de las publicaciones generadas a partir de la ...
Copulatory dialogue: female spiders sing during copulation to influence male genitalic movements
(Animal Behaviour, 2006, 72, 413-421, 2006)
Female behaviour during copulation that could function as communication with the male is probably more common than previously appreciated, but its functional significance remains little studied. Stridulation during copulation ...
Movements and morphology under sexual selection: tsetse fly genitalia
(Ethology Ecology & Evolution 22: 385–391, 2010, 2010-04-17)
SHÖN (2009, Ethology Ecology & Evolution 21: 161–172) pointed out that in order
to understand the functional morphology of sexually selected structures that are used
as signaling devices in birds, it is crucial to ...
Egg sac construction by folding dead leaves in Pozonia nigroventris and Micrathena sp. (Araneae: Araneidae)
(2010)
Published descriptions of egg sac construction behavior in araneids are scarce. We describe egg sac construction and oviposition in one individual of the poorly known araneid Pozonia nigroventris (Bryant 1936) and two ...
Tie them up tight: wrapping by Philoponella vicinaspiders breaks, compresses and sometimes kills their prey
(2006)
We show that uloborid spiders, which lack the poison glands typical of nearly all other spiders, employ thousands of wrapping movements with their hind legs and up to hundreds of meters of silk line to make a shroud that ...
Possible Fisherian Changes in Female Mate-Choice Criteria in a Mass-Reared Strain of Ceratitis capitata (Diptera: Tephritidae)
(Annals of the Entomological Society of America Vol. 93, no. 2, 343-345, 2000)
The frequent interruption of male courtship in highly crowded mass-rearing cages of
Ceratitis capitata (Wiedemann) was correlated with changes in both male courtship and female
acceptance criteria in a mass-reared Costa ...
The hub as a launching platform: rapid movements of the spider Leucauge mariana (Araneae: Tetragnathidae) as it turns to attack prey
(The Journal of Arachnology arac-39-01-13.3d 22/12/10 13:25:38 1 Cust # Hi10-76, 2011)
Spiders are effectively blind with respect to the lines in their webs, and they commonly use exploratory leg movements to find lines, just as a blind man finds objects using a cane. Nevertheless, a mature female Leucauge ...
Experimental demonstration of possible cryptic female choice on male tsetse fly genitalia
(J. Insect Physiol. 2009 Nov; 55(11): 989-996, 2009)
A possible explanation for one of the most general trends in animal evolution – rapid divergent evolution
of animal genitalia – is that male genitalia are used as courtship devices that influence cryptic female
choice. ...
