Similarities in Evasive Behavior of Wolf Spiders (Araneae: Lycosidae), American Toads (Anura: Bufonidae) and Ground Beetles (Coleopterea: Carabidae) [PDF]

open access: yes, 2017
(excerpt) While collecting newly metalnorphosed American toads, Bufo anlericanus Holbrook, we have observed that they exhibited evasive behavior similar to that of adults of the wolf spiders, Pardosa saxatilis (Hentz), Pirata insularis Emerton, Pirata ...

Beneficial Effects of Ants and Spiders on the Reproductive Value of Eriotheca gracilipes (Malvaceae) in a Tropical Savanna. [PDF]

open access: yesPLoS 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 ...

Molecular Spiders in One Dimension [PDF]

open access: yes, 2007
Molecular spiders are synthetic bio-molecular systems which have "legs" made of short single-stranded segments of DNA. Spiders move on a surface covered with single-stranded DNA segments complementary to legs.

The common house spider, Parasteatoda tepidariorum, maintains silk gene expression on sub-optimal diet.

open access: yesPLoS ONE, 2020
Cobweb weaving spiders and their relatives spin multiple task-specific fiber types. The unique material properties of each silk type result from differences in amino acid sequence and structure of their component proteins, primarily spidroins (spider ...

Effects of Wolf Spiders’ Captive Environment on Their Locomotor and Exploratory Behaviours

open access: yesInsects, 2022
Here I detail the effects of the abiotic/captive environment of an adult wandering spider, Pardosa saltans (Lycosidae) on its behaviour. These studies focused on spiders collected as adults in their natural environment and spiders developed in the ...

Terricolous Spiders (Araneae) of Insecticide-Treated Spruce-Fir Forests in West-Central Maine [PDF]

open access: yes, 2017
Spiders of 12 families, 42 genera, and at least 62 species were captured in linear-pitfall traps placed in insecticide-treated (Sevin-4-Oil®, Dipel 4L ®, Thuricide 16B®) and untreated spruce-fIr forests of west-central Maine.

Divergence in gut bacterial community between females and males in the wolf spider Pardosa astrigera

open access: yesEcology and Evolution, 2022
Sex is one of the important factors affecting gut microbiota. As key predators in agroforestry ecosystem, many spider species show dramatically different activity habits and nutritional requirements between females and males. However, how sex affects gut

Novel decorating behaviour of silk retreats in a challenging habitat [PDF]

open access: yesPeerJ, 2022
Many ecological interactions of spiders with their potential prey and predators are affected by the visibility of their bodies and silk, especially in habitats with lower structural complexity that expose spiders. For instance, the surface of tree trunks

Plant–animal interactions between carnivorous plants, sheet‐web spiders, and ground‐running spiders as guild predators in a wet meadow community

open access: yesEcology and Evolution, 2020
Plant–animal interactions are diverse and widespread shaping ecology, evolution, and biodiversity of most ecological communities. Carnivorous plants are unusual in that they can be simultaneously engaged with animals in multiple mutualistic and ...

A Study of Spiders (Araneae) on Maple Trees (Acer Spp.) [PDF]

open access: yes, 2017
We began this study to determine whether spider species occur randomly on maple species or whether they are selective in picking either their host species or their position on that host.
