Occupation Times on the Legs of a Diffusion Spider. [PDF]
Entropy (Basel)We study the joint moments of occupation times on the legs of a diffusion spider. Specifically, we give a recursive formula for the Laplace transform of the joint moments, which extends earlier results for a one-dimensional diffusion. For a Bessel spider, of which the Brownian spider is a special case, our approach yields an explicit formula for the ...

Mantidfly larvae use cues on substrate to locate and distinguish different sexes and life stages of potential spider hosts [PDF]
Scientific ReportsIn many animals, early-life decisions influence long-term fitness. Mantidflies are spider egg predators; their tiny larvae climb aboard spiders to find eggs, but little is known about how they find spiders. We tested the hypothesis that mantidfly larvae (

An Introduction to Some Common and Charismatic Florida Spiders
EDIS, 2023 Florida has a rich diversity of spiders that vary greatly in body shape, size, color, hunting strategy, and habitat. While spiders are often feared, they are generally non-aggressive and provide essential ecosystem services, such as controlling pest ...

Coloring with Spiders: Our Favorites from Florida
EDIS, 2023 Florida has a rich diversity of spiders that vary greatly in body shape, size, color, hunting strategy, and habitat. While spiders are often feared, they are generally non-aggressive and provide essential ecosystem services, such as controlling pest ...

Unintended importation of tropical jumping spiders (Salticidae) into a laboratory monkey colony via banana supply [PDF]
Primate Biology, 2020 This report describes a case of unintended importation of tropical baby jumping spiders to a laboratory monkey colony. The spiders were detected in a cocoon attached to a banana for monkey consumption.

PLoS ONE, 2021 To investigate a specificity of spiders as a prototypical fear- and disgust-eliciting stimuli, we conducted an online experiment. The respondents rated images of 25 spiders, 12 non-spider chelicerates, and 10 other arthropods on a fear and disgust 7 ...

Spider movement, UV reflectance and size, but not spider crypsis, affect the response of honeybees to Australian crab spiders. [PDF]
PLoS ONE, 2011 According to the crypsis hypothesis, the ability of female crab spiders to change body colour and match the colour of flowers has been selected because flower visitors are less likely to detect spiders that match the colour of the flowers used as hunting

The trace reconstruction problem for spider graphs [PDF]
Discrete Mathematics, 346(1), 113115 (2022), 2022 We study the trace reconstruction problem for spider graphs. Let $n$ be the number of nodes of a spider and $d$ be the length of each leg, and suppose that we are given independent traces of the spider from a deletion channel in which each non-root node is deleted with probability $q$. This is a natural generalization of the string trace reconstruction

Epigaeic spider response to sagebrush steppe restoration treatments
Ecosphere, 2022 Epigaeic (ground‐active) spiders are dominant predators of arthropods and are important prey for vertebrates in sagebrush steppe systems. As part of the Sagebrush Steppe Treatment Evaluation Project (SageSTEP), the response of epigaeic spiders to ...

Beneficial Effects of Ants and Spiders on the Reproductive Value of Eriotheca gracilipes (Malvaceae) in a Tropical Savanna. [PDF]
PLoS ONE, 2015 Predators affect plant fitness when they forage on them and reduce the action of herbivores. Our study evaluates the complementary effects of spiders and ants that visit the extrafloral nectaries of Eriotheca gracilipes (Malvaceae) on the production of ...
