Body size, energetic and foraging mode of raptors in central Chile - An inference
An inferential analysis of the foraging mode (opportunist or mediate by prey selection) of a taxonomic assemblage of raptors in central Chile was conducted. The analysis of energetic aspects such as daily requirements of ...
Extreme reduction in body size and reproductive output associated with sandy substrates in two anuran species
(Brill Academic Publishers, 2008-10)
Geographic variation in body size and reproductive traits has been reported in a wide range of organisms, including amphibians. Most studies have focused on latitudinal and/or altitudinal variation where differences in ...
Parasite body volume and infracommunity patterns in the southern pomfret Brama australis (Pisces: Bramidae)
(Sociedad de Biología de Chile, 2002)
Size-fecundity relationships and reproductive investment in female frogs in the Pantanal, south-western Brazil
The ovarian complement of anurans exhibiting different reproductive modes is highly diverse, and intraspecific variation in reproductive output of anurans is generally related to variation in female properties and/or ...
Relationship between body size and flying-related structures in Neotropical social wasps (Polistinae, Vespidae, Hymenoptera)
(SPRINGERNEW YORK, 2012)
Body size influences wing shape and associated muscles in flying animals which is a conspicuous phenomenon in insects, given their wide range in body size. Despite the significance of this, to date, no detailed study has ...
Effect of body size on the abundance of ectoparasitic mites on the wild rodent Oligoryzomys nigripes
(Walter De Gruyter Gmbh, 2015-09-01)
The abundance of parasites on a host can be affected by several factors; in this study, we investigated the influence of sex and body size of the host rodent Oligoryzomys nigripes on the abundance of ectoparasitic mites ...
Geographic and climatic factors related to a body-size cline in Dichroplus pratensis Bruner, 1900 (Acrididae, Melanoplinae)
(Orthopterists' Society, 2008-12)
We studied geographic body size variation in males and females of 25 populations of the South American melanopline grasshopper Dichroplus pratensis Bruner, 1900, along more than 22 degrees of latitude (S) and between 0 and ...
Life-History Evolution on Tropidurinae Lizards: Influence of Lineage, Body Size and Climate
(PUBLIC LIBRARY SCIENCE, 2011)
The study of life history variation is central to the evolutionary theory. In many ectothermic lineages, including lizards, life history traits are plastic and relate to several sources of variation including body size, ...
Differential scaling of locomotor performance in small and large terrestrial mammals
(Company of Biologists Ltd, 2002)
It has been observed that the relationship between locomotor performance and body mass in terrestrial mammals does not follow a single linear trend when the entire range of body mass is considered. Large taxa tend to ...
