Visual odometry in the wolf spider Lycosa tarantula (Araneae: Lycosidae).
The wolf spider Lycosa tarantula homes using path integration. The angular component of the displacement is measured using a polarized-light compass associated with the functioning of the anterior median eyes. However, how L. tarantula estimates the linear component of the displacement was not known prior to this investigation. The ability of L. tarantula to gauge the distance walked after bein...
متن کاملCircadian Rhythms of Locomotor Activity in Lycosa tarentula (Araneae, Lycosidae) and the Pathways of Ocular Entrainment
Lycosa tarentula is a ground-living spider that inhabits a burrow where it awaits the appearance of prey or conspecifics. In this study, circadian rhythms of locomotor activity were examined as well as the ocular pathway of entrainment. Thirty-three adult virgin females were examined under constant darkness (DD); all of them exhibited robust circadian rhythms of locomotor activity with period a...
متن کاملAnterior Median Eyes of Lycosa Tarentula (araneae, Lycosidae) Detect Polarized Light: Behavioral Experiments and Electroretinographic Analysis
We studied solar light cues that may be used by Lycosa tarentula (Linnaeus 1758) (Araneae, Lycosidae) for homing. Experiments performed under clear skies, under overcast skies, and under clear skies as seen through a plastic sheet (which changed the polarization from linear to elliptical), allowed us to discover which attributes of daylight were used by the spiders during orientation and homing...
متن کاملMolecular systematics of the wolf spider genus Lycosa (Araneae: Lycosidae) in the Western Mediterranean Basin.
In this study, we present the first molecular phylogeny of the wolf spider genus Lycosa Latreille, 1804 in the Western Mediterranean Basin. With a wide geographic sampling comprising 90 localities and including more than 180 individuals, we conducted species delimitation analyses with a Maximum Likelihood approach that uses a mixed Yule-coalescent model to detect species boundaries. We estimate...
متن کاملDevelopment of a sampling strategy and sample size calculation to estimate the distribution of mammographic breast density in Korean women.
Mammographic breast density is a known risk factor for breast cancer. To conduct a survey to estimate the distribution of mammographic breast density in Korean women, appropriate sampling strategies for representative and efficient sampling design were evaluated through simulation. Using the target population from the National Cancer Screening Programme (NCSP) for breast cancer in 2009, we veri...
