Models, mechanisms and pathways of succession
(1987)
The study of succession has been hampered by the lack of a general theory. This is illustrated by confusion over basic concepts and inadequacy of certain models. This review clarifies the basic ideas of pathway, mechanism, ...
Heterospecific Vocal Interactions in a Frog from the Southern Temperate Forest, Batrachyla taeniata
(2011)
Animals using sound communication employ different strategies to overcome interferences from biotic and abiotic sources. However, interactions among acoustically active species have been studied to a very limited extent. ...
Kin recognition in the largely solitary bee, manuelia postica (Apidae: Xylocopinae)
(2010)
The recognition of conspecifics is a central issue to social behaviour. In eusocial hymenopterans, kin recognition has been clearly demonstrated. Manuelia postica is a largely solitary bee species in which larvae develop ...
Frequency-modulated vocalizations of eupsophus queulensis (Anura: Cycloramphidae)
(2009)
The advertisment calls of the recently described frog Eupsophus queulensis (Cycloramphidae) are analyzed, based on recordings of seven males. Eupsophus queulensis emits an advertisment call consisting of a harmonic-rich ...
Allozyme divergence in two syntopic Liolaemus of the Liolaemus monticola group (Squamata: Tropiduridae)
(Society for the Study of Amphibians and Reptiles, 2003)
Genetic divergence between two traditionally recognized subspecies, Liolaemus monticola chillanensis and Liolaemus monticola ssp, was assessed by allozymic comparison. Both morphotypes are syntopic and restricted to the ...
