Phylogenetic signal, evolutionary process, and rate
A recent advance in the phylogenetic comparative analysis of continuous traits has been explicit, model-based measurement of “phylogenetic signal” in data sets composed of observations collected from species related by a ...
Geographical variation in head shape of a Neotropical group of toads: the role of physical environment and relatedness
(Wiley-Blackwell, 2017-02-01)
In this study we review the morphological variation within the Rhinella crucifer species group using geometric morphometrics. We sampled 270 specimens from 78 localities comprising all genetic units delimited for the group. ...
Phylogenetic signal of nematocysts in Staurozoa (Cnidaria)

Evolution of Climatic Related Leaf Traits in the Family Nothofagaceae
(2018)
The current relationship between leaf traits and environmental variables has been widely used as a proxy for climate estimates. However, it has been observed that the phylogenetic relationships between taxa also influence ...
Phylogenetic signal of photobiont switches in the lichen genus Pseudocyphellaria s. l. follows a Brownian motion model
(Springer, 2017-06)
Lichen symbioses are defined as a symbiotic relationship between a mycobiont (generally an ascomycete) and one or more photobionts (green algae or/and cyanobacteria). It was proposed that cephalodia emancipation is an ...
Non-congruent fossil and phylogenetic evidence on the evolution of climatic niche in the Gondwana genus Nothofagus
(WILEY-BLACKWELL, 2016)
AimWe used fossil and phylogenetic evidence to reconstruct climatic niche evolution in Nothofagus, a Gondwana genus distributed in tropical and temperate latitudes. To assess whether the modern distribution of the genus ...
Phylogenetic signal of subsets of morphological characters: a case study in the genus erythemis (anisoptera: libellulidae)
(Caldasia, 2014-06-05)
Erythemis Hagen, 1861 shows a considerable variation in genitalic characters, body coloration and wing venation. Since it is known that these traits are affected by different kinds of selection that probably blur their ...
Consequences of the last glacial maximum on Nyctelia confusa (Coleoptera: Tenebrionidae) in Patagonia
(Consequences of the last glacial maximum on Nyctelia confusa (Coleoptera: Tenebrionidae) in Patagonia, 2016)
The Last Glacial Maximum (LGM) has affected the population size and spatial distribution of a number of organisms in southern Patagonia. It has been hypothesized that species were able to persist in isolated refuges, which ...
