Large mammal burrows in late Miocene calcic paleosols from central Argentina: Paleoenvironment, taphonomy and producers
(PeerJ Inc., 2018-05)
Large cylindrical sediment-filled structures interpreted as mammal burrows occur within the loess-paleosol sequence of the late Miocene Cerro Azul Formation of central Argentina. A total of 115 burrow fills from three ...
Microvertebrates preserved in mammal burrows from the Holocene of the Argentine Pampas: a taphonomic and paleoecological approach
(Taylor & Francis, 2017-01)
Microvertebrates are a major component of many assemblages recovered from the Quaternary of the Argentine Pampas. The main goal of this paper is to analyse the taphonomic history of a Holocene microfossil bonebed, recovered ...
Large tetrapod burrows from the Middle Triassic of Argentina: A behavioural adaptation to seasonal semi-arid climate?
(Wiley Blackwell Publishing, Inc, 2013-04)
We report the discovery of large burrow casts in the early Middle Triassic Tarjados Formation, at Talampaya National Park, north-western Argentina. Facies analysis indicates the burrows are preserved in sandbars deposited ...
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 ...
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 ...
SMALL MAMMAL PREY SELECTION BY TWO OWL SPECIES IN SOUTHEASTERN BRAZIL
(RAPTOR RESEARCH FOUNDATION INC, 2008)
A variety of factors influence prey selection by predators. Because Barn Owls (Tyto alba) and Burrowing Owls (Athene cunicularia) differ in size and foraging tactics, we expected differential predation on small mammal prey. ...
Terrestrial mammals of the Americas and their interactions with plastic waste
(Springer, 2023)
Plastics have brought many benefits to society, but their mismanagement has turned them into a serious environmental problem. Today, the effects of plastic waste on wildlife are becoming increasingly evident. Since studies ...
