Labra, Antonieta; Cortez, Soledad; Niemeyer, Hermann M. (2003)We explored chemical discrimination of own vs. novel space by different age classes (neonates, juveniles, and adults) of the lizard Liolaemus bellii, during pre- and post-hibernation seasons. We recorded the number of ...

Escobar, Claudio M.; Escobar, Carlos A.; Labra, Antonieta; Niemeyer, Hermann M. (2003)The chemical composition of secretions of precloacal pores from two populations of the lizard Liolaemusfabiani (Puilar and Punta-Brava) were compared. This is an endemic species from the Atacama Salt Flat (26°46'S 68° 14'W; ...

Labra, Antonieta; Hoare, Misque (Springer Verlag, 2015)© 2014, Springer-Verlag Berlin Heidelberg and ISPA.In a predator–prey interaction, the fitnesses of the predator and the prey depend on their abilities to recognize each other, a process that may involve different sensory ...

Fong, Lydia J. M.; Navea Bravo, Fernando; Labra, Antonieta (Springer, 2020)For a prey, its best ticket to stay alive is to get early and accurate information on predation risk and so, escape from predation at low cost. Some prey species have evolved the ability to eavesdrop signals intended for ...

Trigosso-Venario, Rodrigo; Labra, Antonieta; Niemeyer, Hermann M. (2002)For territorial organisms, recognition of familiar individuals can reduce the frequency and intensity of aggressive encounters ('dear enemy' phenomenon), stabilize social systems, and reduce the cost of territory maintenance. ...
-
Labra, Antonieta; Niemeyer, Hermann M. (Kluwer Academic/Plenum Publishers, 1999)Experimental tests were conducted to determine whether females and males of the tree-dwelling lizard Liolaemus tenuis (Tropiduridae) show intraspecific chemical recognition during breeding and postreproductive seasons. ...

Reyes Olivares, Claudio; Guajardo Santibáñez, Andrés; Segura, Bernardo; Zañartu, Nicolás; Penna Varela, Mario; Labra, Antonieta (Wiley, 2020)Vertebrate predation by invertebrates has been classically underexplored and thus underestimated, despite the fact that many arthropods consume vertebrates. To shed some light on the relevance that spider predation may ...

Predation and spatial distribution of the lizard Podarcis hispanica atrata: An experimental approach Castilla, Aurora M.; Labra, Antonieta (Elsevier B.V., 1998)This study reports on an experiment designed to quantify potential predation by birds on the lizard Podarcis hispanica atrata in the Columbretes islands (Castellon, Spain). We used plasticine replicas to examine predation ...
-
Hoare, Misque; Labra, Antonieta (2013)The evolution and functions of avian and mammalian antipredator calls are well understood, which contrasts with a lack of progress in reptiles. Here, we present the first investigation of the functions of a distress call ...
-
Labra, Antonieta; Escobar, Carlos A.; Aguilar, Paz M.; Niemeyer, Hermann M. (Sociedad de Biologia de Chile, 2002)Experimental tests were conducted with the lizard Liolaemus tenuis (Tropiduridae), to determine the potential sources of pheromones used in its chemical communication, centered in the phenomenon of self-recognition. During ...

Seligmann, Hervé; Labra, Antonieta (Elsevier Ireland Ltd, 2013)Codons expanded by a silent position (quadruplet or tetracodons) may solve the conundrum that at life's origins, the weak tricodon-anticodon interactions could not promote translation in the absence of complex ribosomes. ...
-
Labra, Antonieta (2007)Ecological and phylogenetic factors determine which sensory modalities organisms use in their day-to-day activities. Among lizards, empirical studies indicate a tight association between foraging strategies and the ability ...
-
Seligmann, Hervé; Labra, Antonieta (Elsevier, 2014)Mitochondrial light strand DNA replication is initiated at light strand replication origins (OLs), short stem-loop hairpins formed by the heavy strand DNA. OL-like secondary structures are also formed by heavy strand DNA ...
