Modes and Frequencies of Colonization and its Relation to Extinctions, Habitat and Seasonality in the Social Spider Anelosimus Eximius in the Amazon (Araneidae: Theridiidae)
(1993-01-01)
Numbers of colonizations and extinctions of incipient colonies of the social spider Anelosimus eximius were greater at the edges of Amazonian forest than in continuous forest. The frequency of colony foundations by sociotomy, ...
Cotinine: A Therapy for Memory Extinction in Post-traumatic Stress Disorder
(NLM (Medline), 2018)
Preventing Return of Fear in an Animal Model of Anxiety: Additive Effects of Massive Extinction and Extinction in Multiple Contexts
(Behavior Therapy 44 (2013) 249–261, 2013)
Fear conditioning and experimental extinction have been
presented as models of anxiety disorders and exposure
therapy, respectively. Moreover, the return of fear serves as
a model of relapse after exposure therapy. Here ...
Education as a tool for addressing the extinction crisis: Moving students from understanding to action
(Universidad de Costa Rica, 2010)
Reacquisition of Associative Tolerance to Ethanol: The Effect of Massive Extinction
The repeated intake of certain drugs produces tolerance, that is, a decrease in its effects and therefore the need to take larger doses. From the Pavlovian conditioning paradigm, the present research examined in two experiments ...
The late Pleistocene-early Holocene rails (Gruiformes: Rallidae) of Laguna de Tagua Tagua Formation, central Chile, with the description of a new extinct giant coot
(Elsevier, 2020)
Rallidae, which includes coots, crakes and moorhens, is one of the most speciose families among the Gruiformes. This family exhibits a pattern of diversification that has involved significant episodes of regional expansion ...
Requirement for BDNF in the reconsolidation of fear extinction
(Society for Neuroscience, 2015-04)
Therapies based on the impairment of reconsolidation or the enhancement of extinction offer the possibility of decreasing the persistent recollection of distressing memories. However, the direct interplay between reconsolidation ...
Context-dependent extinction of an appetitive operant conditioned response in infant rats
(John Wiley & Sons Inc, 2017-03)
The present study evaluated context-dependent learning under an operant conditioning procedure in infant rats. Preweanling rats were trained in context A during postnatal days (PDs) 16 and 17 to learn an appetitive operant ...
Selective extinction of late Neogene bivalves on the temperate Pacific coast of South America
(PALEONTOLOGICAL SOC INC, 2007)
We assessed selective extinction patterns in bivalves during a late Neogene mass extinction event observed along the temperate Pacific coast of South America. The analysis of 99 late Neogene and Quaternary fossil sites ...
Cladistics and mass extinctions: the example of conulariids (Scyphozoa, Cnidaria) and the End Ordovician Extinction Event
(Oxford, 2014)
The End Ordovician Extinction Event (EOEE) had little impact on supra-specific diversity and disparity within the order Conulariida (Scyphozoa, Cnidaria). With two possible exceptions (Exoconularia and Glyptoconularia), ...
