Seasonal population dynamics in Lucilia eximia (Wiedemann) (Diptera : Calliphoridae)
(Entomological Society Brasil, 2006-11-01)
In this study the seasonal variation of fecundity, wing and tibia sizes were investigated in natural populations of Lucilia eximia (Wiedemann) as an attempt to determine the variations in life history of the species ...
Body Size and Sexual Dimorphism in the Southernmost Subspecies of the Burrowing Owl (Athene cunicularia cunicularia)
(Raptor Research Foundation, 2015-12)
We studied body size and sexual dimorphism in the southernmost subspecies of the Burrowing Owl (Athene cunicularia cunicularia) at the Pampas of Argentina, and we compared our data with those from other subspecies in the ...
Allometry for Sexual Size Dimorphism in Stoneflies Defies the Rensch's Rule
(Entomological Soc Brasil, 2014-04-01)
The Rensch's rule predicts that male-biased sexual size dimorphism (SSD) increases with body size, while female-biased SSD (FBSSD) decreases. In insects, many groups follow this rule, but the evidence suggests that it is ...
Size-at-age or structure shift: Which hypothesis explains smaller body size of the fiddler crab Leptuca uruguayensis in northern populations?
(2021-06-05)
The mean body size decrease is known as the third most important global consequence of climate change to wild life. Rising temperatures may lead to decreased mean body size of organisms and change their ecological role in ...
Lama Guanicoe (Muller, 1776) body size in continental Patagonia and Tierra del Fuego
(Elsevier Masson, 2015-04-11)
Lama guanicoe (Muller, 1776) is one of the most important South American large mammal species for both biologists, ecologists and archaeologists, and body size of modern and prehistoric populations of guanaco has been one ...
Species richness, abundance, and body size relationships from a neotropical chironomid assemblage: Looking for patterns
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2008)
We investigated two of the most studied relationships in the macroecological research program (species richness vs. body size and abundance vs. body size) of a local chironomid assemblage from southeastern Brazil. Although ...
Sexually dimorphic traits and male fertility in a paper wasp
(Oxford Univ Press, 2020-07-01)
Females of many social Hymenoptera commit their reproductive potential to a single male; they mate once and never re-mate. Sexual selection theory predicts that under this regimen female precopulatory mate choice is crucial. ...
Fishing-down within populations harms seed dispersal mutualism
(2018-03-01)
Large fish are often the most effective seed dispersers, but they are also the preferred target for fisheries. We recently started to comprehend the detrimental impacts of the extirpation of large frugivorous fish species ...
