(1994)Young Drosophila larvae (24-28 and 48-52-h old) show a preference for feeding in dark environments, while older larvae (72-76 h post-hatching) prefer more illuminated environments. Changes in the photoresponse during larval ...
-
(2009)Meiosis is a complex type of cell division that involves homologous chromosome pairing, synapsis, recombination, and segregation. When any of these processes is altered, cellular checkpoints arrest meiosis progression and ...

(Public Library of Science, 2014)The current genetic makeup of Latin America has been shaped by a history of extensive admixture between Africans, Europeans and Native Americans, a process taking place within the context of extensive geographic and social ...
-
(2009)Females in several ungulates transfer milk to non-filial (NF) offspring, in a process known as allonursing. This behavior is less common in monotocous species, including most ungulates, and it has been associated ...
-
(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 ...
-
(Blackwell Munksgaard, 1999)Seeds of seven tree species, six shrub species, and one epiphyte were tested for their rates of removal by seed predators in two remnant patches (15-20 ha) of old-growth temperate forest in Chiloe Island, southern Chile ...

(1993)Frugivores affect Cryptocarya alba seeds both positively and negatively by the simple act of removing the pericarp of the fruits. Germination is both increased and advanced but simultaneously seed mortality by rodent ...
-
(Academic Press, 2002)Under predation risk, prey may prioritize antipredator behaviours and sacrifice feeding. However, energetically constrained animals may choose to sacrifice or change antipredator responses and accept relatively greater ...
-
(1992)Evaluated germination of Cryptocarya alba seeds dispersed by Dusicyon culpaeus. Defecated seeds are viable and germinate at higher proportion than controls. in the field, germination was greater for seeds located beneath ...
-
(2012)Most neurodegenerative diseases involve the accumulation of misfolded proteins in the nervous system. Impairment of protein degradation pathways such as autophagy is emerging as a consistent and transversal pathological ...
-
(2002)To explore the bacterial microbiota in Chilean oyster (Tiostrea chilensis), a molecular approach that permits detection of different bacteria, independently of their capacity to grow in culture media, was used. Bacterial ...
-
(Nature Publishing Group, 2019)© 2018, International Society for Microbial Ecology.Larger volumes of sea ice have been thawing in the Central Arctic Ocean (CAO) during the last decades than during the past 800,000 years. Brackish brine (fed by meltwater ...

(1990)The rare Darwin's fox Dusicyon fulvipes (Martin, 1837) was thought to be restricted to Chiloé Island in southern Chile, and to be a subspecies of Dusicyon griseus. We report the finding of a continental population of D. ...
