Neoichnology of mygalomorph spiders: Improving the recognition of spider burrows in the geological record
(Elsevier B.V., 2021-06-01)
The female Mygalomorphae spiders are sedentary and long-lived organisms that spend most of their lives inside their burrows. Neoichnological studies provide relevant information that can help the recognition of these ...
Wolf spider burrows from a modern saline sandflat in central Argentina: Morphology, taphonomy and clues for recognition of fossil examples
(PeerJ Inc., 2018-06)
Pavocosa sp. (Lycosidae) burrows found in an open sparsely vegetated area on the edge of the Gran Salitral saline lake, in central Argentina, are described. Burrows were studied by capturing the occupant and casting them ...
Female and juvenile burrow-digging in Allocosa brasiliensis, a South American sand-dwelling wolf spider
(British Arachnological Society, 2015-02)
Allocosa brasiliensis is a sand-dwelling wolf spider that constructs burrows along the coasts of rivers, lakes and the Atlantic Ocean in Argentina, Brazil and Uruguay. This species shows a reversal in typical sex roles in ...
Association between neotropical burrowing spiders (araneae: nemesiidae) and mites (acari: heterostigmata, scutacaridae)
(Societe Acarologique, 2002-01)
Whilst collecting burrowing spiders of the family Nemesiidae from 16 localities in Argentina, phoretic mites were found on Stenoterommata iguazu, Stenoterommata platense and Stenoterommata uruguai. These mites are described ...
Previous experience and substrate matter: Plasticity in burrow digging in a South American wolf spider
(Gauthier-Villars/Editions Elsevier, 2019-10)
Burrowing behavior can be affected by substrate conditions such as percentages of minerals, organic substances, granulometry, and biotic factors like densities of burrowing individuals, potential prey, and predators. ...
Surface Soil Type Preference for Burrowing of the Endangered and Endemic Trapdoor Spider Calathotarsus simoni (Araneae: Migidae)
(British Arachnological Society, 2018-07-01)
Calathotarsus simoni Schiapelli & Gerschman, 1975 is an endemic and rare trapdoor spider that lives exclusively in the mountainous systems of southern Buenos Aires province, central Argentina. In previous studies, authors ...
A matter of choice: Substrate preference by burrow-digging males of a sand-dwelling spider
(Springer Tokyo, 2018-09)
Animals may build refuges to avoid predation, to communicate, to mate, and to protect against extreme temperatures, among other factors. Allocosa senex is a wolf spider that constructs burrows in the coastal sand dunes of ...
Another migid in the wall: natural history of the endemic and rare spider Calathotarsus simoni (Mygalomorphae: Migidae) from a hill slope in central Argentina
(Taylor & Francis, 2014-03)
A population of Calathotarsus simoni Schiapelli and Gerschman (1975) was discovered on a hillside in the Ventania system, Argentina. Our objectives were to quantify burrow density, record burrow morphology and door ...
A contribution to the knowledge of burrows and reproductive biology of Stenoterommata platensis Holmberg (Mygalomorphae: Nemesiidae)
(GAZI University, 2014-01)
Stenoterommata platensis is a medium-sized nemesiid spider that lives in
open burrows. The biology of the Nemesiidae is almost unknown. We describe the courtship and mating of S. platensis for the first time based on two ...
No pain, no gain: Male plasticity in burrow digging according to female rejection in a sand-dwelling wolf spider
(Elsevier Science, 2017-07)
Behavioral plasticity allows individuals to reversibly respond to short-term variations in their ecological and social environment in order to maximize their fitness. Allocosa senex is a burrow-digging spider that inhabits ...
