Latitudinal trends in digestive flexibility: testing the climatic variability hypothesis with data on the intestinal length of rodents
(2008)
Flexibility of digestive features can be understood considering the benefits of digestion, which links animal foraging to metabolizable energy and nutrient gain, and its costs, which are partly indexed by digestive tract ...
Can the pattern of juvenile recruitment and population structure of the speckled swimming crab Arenaeus cribrarius (Decapoda: Brachyura) be determined by geographical variations?
(2015-12-01)
This study evaluated the effect of environmental stimuli and selective pressures in different geographical areas along a latitudinal gradient, on the juvenile recruitment, population structure, and sex ratio of the speckled ...
Variability of water relations and photosynthesis in Eucryphia cordifolia Cav. (Cunoniaceae) over the range of its latitudinal and altitudinal distribution in Chile
(2010-04-06)
The aim of this study was to investigate, during
the summer of the year 2008, the variation in leaf water and
photosynthetic characteristics of Eucryphia cordifolia Cav.
(Cunoniaceae) along its broad latitudinal ...
New records and range extensions of reef fishes in the Western South Atlantic, with comments on reef fish distribution along the Brazilian coast
(Sociedade Brasileira de Zoologia, 1999)
An inverse latitudinal biodiversity pattern in asellote isopods (Crustacea, Peracarida) from the Southwest Atlantic between 35° and 56°S
(Springer, 2014-03)
A distinct trend of decreasing biodiversity from the tropics to the poles is well-known for terrestrial organisms. This pattern, however, is less clear in marine systems. In the present study, an inverse latitudinal ...
Seedling Mortality and Herbivory Damage in Subtropical and Temperate Populations: Testing the Hypothesis of Higher Herbivore Pressure Toward the Tropics
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
Herbivory rates are generally thought to be higher in tropical than in temperate forests. Nevertheless, tests of this biogeographic prediction by comparing a single plant species across a tropical-temperate range are scarce. ...
