Mounting a specific immune response increases energy expenditure of the subterranean rodent Ctenomys talarum (tuco-tuco): Implications for intraspecific and interspecific variation in immunological traits
(Company of Biologists, 2010-03)
It was recently hypothesised that specific induced defences, which require substantial time and resources and are mostly beneficial against repeated infections, are more likely to be favoured in 'slow-living-pace' species. ...
Ecological divergence and hybridization of Neotropical Leishmania parasites
(National Academy of Sciences, 2020)
The tropical Andes are an important natural laboratory to understand speciation in many taxa. Here we examined the evolutionary history of parasites of the Leishmania braziliensis species complex based on whole-genome ...
Intra- and inter-specific vocal variation in three Neotropical cardinalids (Passeriformes: Fringillidae) and its relationship with body mass
(Csiro Publishing, 2014-03)
The negative relationship between song frequencies and body weight found by Wallschläger in 1980 is well supported by several studies considering a large number of bird species. However, the results obtained when comparing ...
Further Study on the esterase patterns of sibling species in the Drosophila saltans subgroup (saltans group): Intraspecific and interspecific variations in the development
(2006-03-01)
Twenty of the 32 esterase bands previously detected in the adults of D. prosaltans, D. saltans and D. austrosaltans were found in larvae and pupae studied in this work. The results showed that, in addition to expressing ...
Producción de híbridos interespecíficos entre Nierembergia ericoides y Nierembergia linariaefolia mediante la aplicación de técnicas de rescate embrionario = Production of interspecific hybrids between Nierembergia ericoides and Nierembergia linariaefolia through the application of embryo rescue techniques
(Universidad de Concepción, Chile, 2018)
La hibridación interespecífica es una de las técnicas más utilizadas en el mejoramiento de plantas ornamentales, debido a su alto potencial para obtener vigor híbrido y variación en caracteres, aspectos que no se expresan ...
Spider-fed bromeliads: seasonal and interspecific variation in plant performance
(OXFORD UNIV PRESS, 2011)
Background and Aims Several animals that live on bromeliads can contribute to plant nutrition through nitrogen provisioning (digestive mutualism). The bromeliad-living spider Psecas chapoda (Salticidae) inhabits and breeds ...
Phylogenetic analysis of standard metabolic rate of snakes: a new proposal for the understanding of interspecific variation in feeding behavior
(Springer Heidelberg, 2018)
The current proposal about the variation of standard metabolic rates (SMR) in snakes predicts that SMR is influenced by the feeding frequency (frequent or infrequent feeders). However, feeding frequency in snakes is poorly ...
