Ammonites phylogenetic analysis: state of the art and new prospects

2004

Abstract Two main types of data are available to resolve phylogenies using fossils data: (1) stratigraphic ordering of taxa, and (2) morphological characters. In most phylogenetic studies dealing with ammonites, authors have given priority to the stratigraphic distribution of taxa. This practice is classically justified by the fact that the ammonite fossil record is frequently outstandingly good. In practice, the level of integration of stratigraphic and morphologic information in a single analysis depends on the confidence that authors have in the quality of data. Besides, many evolutionary concepts, which could differ over time and between authors (e.g. anagenesis, cladogenesis, iterative…

Understanding how and why rates of evolutionary diversification vary is a key issue in evolutionary biology, ecology, and biogeography. Evolutionary rates are the net result of interacting processes summarized under concepts such as adaptive radiation and evolutionary stasis. Here, we review the central concepts in the evolutionary diversification literature and synthesize these into a simple, general framework for studying rates of diversification and quantifying their underlying dynamics, which can be applied across clades and regions, and across spatial and temporal scales. Our framework describes the diversification rate (d) as a function of the abiotic environment (a), the biotic envir…

Sports participation in France and Spain: An international comparison of voraciousness for sport

2020

International audience; The societal comparative approach used in this article to assess voraciousness for sport is based on local surveys. The global was studied at a local level, based on a lengthy process of harmonization of quantitative local surveys. The research is carried out in two countries that are geographically close, but quite different to each other: France and Spain. In an increasingly globalized world, the objective is to examine differences in the social uses of physical activities and sports (PAS) between the two populations, by explaining them with respect to the differences between these two societies as a whole. The social differentiations identified in the portfolio si…

Identity and socio-educational responsibilities of the educational mediator and the intercultural mediator: towards a clarification of functions

2012

El presente artículo reconoce que, ante la creciente presencia en escenarios socioeducativos de la figura profesional del mediador en los dos ámbitos principales relacionados con la educación (el escolar y el intercultural), deben identificarse los rasgos idiosincrásicos de cada uno de ellos, lo que no es óbice para reconocer cómo, a pesar de que existen, en efecto, diferencias en la definición de estos dos modelos de mediación, se evidencian aspectos coincidentes que los vinculan a un tronco común: las competencias y responsabilidades socioeducativas que adquieren cada uno de ellos. Las autoras del artículo aplican la metodología comparada para demostrar ambas realidades compatibles en las…

Sexual conflict drives micro- and macroevolution of sexual dimorphism in immunity

2021

Abstract Background Sexual dimorphism in immunity is believed to reflect sex differences in reproductive strategies and trade-offs between competing life history demands. Sexual selection can have major effects on mating rates and sex-specific costs of mating and may thereby influence sex differences in immunity as well as associated host–pathogen dynamics. Yet, experimental evidence linking the mating system to evolved sexual dimorphism in immunity are scarce and the direct effects of mating rate on immunity are not well established. Here, we use transcriptomic analyses, experimental evolution and phylogenetic comparative methods to study the association between the mating system and sexua…

African Law(s)

2023

The book presents a critical rethinking of the study of law in Africa from a comparative law perspective and proposes a new approach on how to consider law in Africa. It highlights the inadequacies of current Western theoretical perspectives in comparative law, especially for studying African law, arguing that they are too eurocentric to fully catch the peculiarities and characteristics of the African “lawscape”. The common thread of the present work is that of consider law in Africa from a different perspective. The aim of the proposed approach is to demonstrate that the African legal culture can be considered at the same level of the Western one, so that – being deeply rooted in the cultu…

Mechanisms of reciprocity and diversity in social networks: a modeling and comparative approach

2018

Individual-based computer models show that different mechanisms, proximity-based or emotional bookkeeping, can lead to reciprocation. By comparing social networks from different computer models with those of empirical data, we show that the models’ social networks bear limited resemblance with some features of the observed social networks. This indicates that additional social processes (third-party awareness) may be needed in these models to represent more accurately the social behavior and interaction patterns observed in group-living animals.

COMPARING THE MARSHALL PLAN AND THE EUROPEAN NEXT GENERATION UE. Models and Legal Tools of International and Supernational Cooperation to Promote Eco…

2022

The article analyzes and compares the European Recovery Plan of 1948, commonly known as the Marshall Plan, for the reconstruction of Europe after the Second World War (paragraphs 2, 2.1, 2.2), and the Next Generation EU (paragraphs 3, 3.1) through the lens and methods of legal comparison and historical analysis. As the description of the law cannot ignore the historicization of the object of study, such comparison is carried out inductively, through the analysis of the legal mechanisms in their concrete attitudes and the construction of descriptive schemes of facts, having regard to the legal discipline, but also to the functional profiles and the context in which the rules are conceived. T…

Hands-on or Video-based Learning with ANTicipation? A Comparative Approach to Identifying Student Motivation and Learning Enjoyment During a Lesson a…

2015

The observation of living animals in school laboratories provides authentic views of biological research. Various studies stress the importance of primary experiences in biology classes. However, educational films may serve as an alternative in some cases. The aim of this study was to investigate student motivation before and after treatments, including (1) an educational film, (2) a hands-on activity with living animals accompanied by an educational film and (3) a hands-on activity with living animals. We investigated the influence of teaching method, gender and class level on student motivation and learning enjoyment. In all treatments, Temnothorax ants were addressed, which can be easily…
