The geometric morphometric (GM) analysis of complex anatomical structures is an ever more powerful tool to study biological variability, adaptation and evolution. Here, we propose a new method (combinland), developed in R, meant to combine the morphological information contained in different landmark coordinate sets into a single dataset, under a GM context. combinland builds a common ordination space taking into account the entire shape information encoded in the starting configurations. We applied combinland to a Primate case study including 133 skulls belonging to 14 species.

Background: The brown dog tick Rhipicephalus sanguineus (sensu stricto) is reputed to be the most widespread tick of domestic dogs worldwide and has also been implicated in the transmission of many pathogens to dogs and humans. For more than two centuries, Rh. sanguineus (s.s.) was regarded as a single taxon, even considering its poor original description and the inexistence of a type specimen. However, genetic and crossbreeding experiments have indicated the existence of at least two distinct taxa within this name: the so-called "temperate" and "tropical" lineages of Rh.

While urban areas expand both in terms of population and built/paved surfaces, cities are facing growing challenges. In particular, the wellbeing and comfort of urban population is of primary importance, and has to be pursued together with other objectives, such as the reduction of energy consumptions and emissions. These issues are all related, since energy consumptions lead to higher emissions, which translate into higher temperatures in cities, thus reduced thermal comfort for pedestrians, and air quality deterioration.

Guest-editor of a Special issue focused on the morphological isoglosses in the Indo-European languages.

In PIE, quality modifiers were expressed by stative verbs and nominal epithets, rather than by special adjectival lexemes. Adjectives did not form a separate lexical class. This made the encoding of the NP constituency less explicit. If we consider what I suggest calling “second-generation IE languages” we can observe a general tendency to create new, more explicit morphological means of dependency marking within a NP. The exact outcomes of this diachronic process vary from one language to another. However, if we parametrise the variation, a common pattern becomes clearly observable.
