Mating system of the burrowing crab Neohelice granulata (Brachyura: Varunidae) in two contrasting environments: Effect of burrow architecture
(Springer, 2012-07)
Few studies conducted in crustaceans have demonstrated how habitat features could shape the mating systems. Here, the burrow of Neohelice granulata was considered as a resource used for mating, and its architecture was ...
Regenerative bioturbation by intertidal burrowing crabs modifies microphytobenthic composition and enhances primary production in SW Atlantic mudflats
(Inter-Research, 2019-12)
In coastal systems, benthic microalgae are important primary producers that significantly contribute to global primary production. Microphytobenthic (MPB) community structure and the ecosystem functions that it mediates ...
Burrowing herbivores alter soil carbon and nitrogen dynamics in a semi-arid ecosystem, Argentina
(Elsevier, 2016-12)
Activities of burrowing herbivores, including movement of soil and litter and deposition of waste material, can alter the distribution of labile carbon (C) and nitrogen (N) in soil, affecting spatial patterning of nutrient ...
Inferring the mating system in the burrowing shrimp Lepidophthalmus bocourti (Decapoda, Axiidea, Callichiridae) from the social structure and sexual dimorphism
(2021-06-01)
Abstract: Most burrowing shrimps (infraorder Axiidea and Gebiidea) are characterized by solitary habits, which led many of these species to evolve a remarkable sexual dimorphism both in body size and chelipeds because of ...
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 ...
Current state of knowledge on Virilastacus species (Crustacea, Decapoda, Parastacidae)
(Pontificia Universidad Católica de Valparaíso, 2017)
Monogamy in the Burrowing Shrimp Axianassa australis Rodrigues & Shimizu, 1992 (Decapoda, Gebiidea, Axianassidae)
(2022-01-01)
Our knowledge of the mating systems in burrowing shrimps (infraorders Axiidea and Gebiidea) is still rather limited. Here we describe the burrow use pattern, sex ratio, and sexual dimorphism of the burrowing shrimp Axianassa ...
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 ...
Taphonomy of modern communal burrow systems of the Plains vizcacha (Lagostomus maximus, Chinchillidae) in the Pampas region of Argentina: implications for the fossil record
(Taylor & Francis, 2017-09)
The Plains vizcacha (Lagostomus maximus) is one of the largest rodents in South America. They live in communal burrow systems (vizcacheras) shaped by complex subterranean galleries which produce a strong impact on the local ...
Do subterranean mammals use the Earth’s magnetic field as a heading indicator to dig straight tunnels?
(PeerJ Preprints, 2018-10-31)
Subterranean rodents are able to dig long straight tunnels. Keeping the course of such “runways” is important in the context of optimal foraging strategies and natal or mating dispersal. These tunnels are built in the ...
