The determination of maturity stages in male elasmobranchs (Chondrichthyes) using a segmented regression of clasper length on total length
2013
A novel statistical method for estimating the stages of maturity in male sharks and skates based on a segmented regression (SRM) is proposed. We hypothesize that this method is able to find the transition points in the three-phase relationship between total length (TL) and clasper length (CL). We applied an SRM to TL–CL data of nine species, from large pelagic sharks (e.g., Carcharhinus falciformis) to small coastal skates (e.g., Rioraja agassizi), captured in the southwestern Atlantic and northeastern Pacific. As expected, SRM detected two breakpoints, defining three maturity stages (immature, maturing, and mature), in six out of nine species. For three species, it was not possible to fin…
The genetic heritage of Alpine local cattle breeds using genomic SNP data
2020
Abstract Background Assessment of genetic diversity and population structure provides important control metrics to avoid genetic erosion, inbreeding depression and crossbreeding between exotic and locally-adapted cattle breeds since these events can have deleterious consequences and eventually lead to extinction. Historically, the Alpine Arc represents an important pocket of cattle biodiversity with a large number of autochthonous breeds that provide a fundamental source of income for the entire regional economy. By using genotype data from medium-density single nucleotide polymorphism (SNP) arrays, we performed a genome-wide comparative study of 23 cattle populations from the Alpine Arc an…
On the origin and diversification of Podolian cattle breeds: testing scenarios of European colonization using genome-wide SNP data
2021
AbstractBackgroundDuring the Neolithic expansion, cattle accompanied humans and spread from their domestication centres to colonize the ancient world. In addition, European cattle occasionally intermingled with both indicine cattle and local aurochs resulting in an exclusive pattern of genetic diversity. Among the most ancient European cattle are breeds that belong to the so-called Podolian trunk, the history of which is still not well established. Here, we used genome-wide single nucleotide polymorphism (SNP) data on 806 individuals belonging to 36 breeds to reconstruct the origin and diversification of Podolian cattle and to provide a reliable scenario of the European colonization, throug…

Bryophyte diversity in the gypsum outcrops of Sicily (Italy)
2020
Abstract: A study on the bryophyte diversity of 12 Sicilian gypsum outcrops, falling in 4 Nature Reserves and 5 Special Areas of Conservation (SAC), is presented in order to increase knowledge about this peculiar flora for which conservation efforts need to be addressed. The bryoflora consists of a total of 85 taxa, 8 liverworts and 77 mosses, most of them belonging to the Pottiaceae family and characterized by xero-morphological adaptations. The bio-ecological analysis has emphasized the prevalence of xerophytic and basiphytic species with life form turf and life strategy colonist. Regarding the gypsicolous character, only one species, Tortula revolvens, behaves as a strict gypso- phyte, a…
The image of the smoking and non-smoking young person
1985
MORE than 1,600 Finnish secondary school pupils between the ages of 12 and 16 completed a question naire about their image of the smoking and non- smoking adolescent. A smoker was described as nervous, unfriendly, untidy, stupid and a low achiever in sport and academic work, but despite this, was seen as a leader. Non-smokers were seen as calm, strong, fairly modest, friendly, tidy and smart, but not as leaders. Older pupils saw the smoker in a more positive light. Those who smoked saw the non- smoker image as positive, and rated the smoking image more highly than did non smokers.

A learning model for the dual evolution of human social behaviors
2003
In this work we modelize, with an abstract mathematical model by computer simulation, the processes that have made to appear in the world a strong duality between orient and occident, by combining changes in conditions of initialization, natural system and the opposition gregarious/individualism of the social behaviors. Finally we present a statistical study of the influence of the repression adaptability, resignation and recycling on the ecological destruction and social evolution. This model can help us to analyze if the current capitalist globalization can be stopped, changed or regulated, and if it is possible to overcome it towards a Free Scientific Society.
