Previous studies on the phylogenetic relationships between lamprey species relied either on a low number of morphological characters related to the feeding apparatus, or on a low number of molecular mitochondrial DNA markers. Here, we apply a multilocus approach to assess the phylogenetic relationships of northern hemisphere lampreys, with a specia...

Abstract In this paper, we analyzed the phylogeny of the section Bulbocodii (genus Narcissus; Amarillydaceae) using the matK and trnL-F fragments of cpDNA in order to review the validity of the recognized taxa. Our results indicate that Narcissus obesus should be considered a valid species, and that N. blancoi is a distinct taxon. In addition, seve...
Chapter
We reviewed 54 studies on teleost fishes and crustaceans inhabiting European waters to test for the emergence of phylogeographic patterns. Concerning latitudinal variation of genetic diversity, we found that: (1) contrary to the predictions of the “central-margin hypothesis,” only a minority of species (~10 %) revealed higher genetic diversity in t...

The molecular analysis of Genista anglica L. and Genista ancistrocarpa Spach in Europe and North Africa validated the separation of these two sister taxa as two distinct genetic entities, strengthening the already described morphological differentiation. A coastal clade of G. ancistrocarpa outlines a biogeographic region that seems to depart geneti...

• A wide range of factors (developmental, physiological, ecological) with unpredictable interactions control variation in leaf form. Here, we examined the distribution of leaf morphologies (simple and complex forms) across angiosperms in a phylogenetic context to detect patterns in the directions of changes in leaf shape. • Seven datasets (diverse...

Many of the fundamental concepts of biology lack consensual, precise definitions. Partly, this is due to a contrast between our discrete language and the continuous character of nature. Some debates over these concepts are confounded by the use of the same terms with different specific meanings, indicating a possible need for an expanded scientific...
Article
In this paper, the phylogenetic relationships of the marine blenny Salaria pavo and the freshwater S. fluviatilis and S. economidisi were analyzed using four molecular markers: the mitochondrial 12S rRNA, 16S rRNA, and the control region and the nuclear first intron of the S7 ribosomal protein. The monophyly of Salaria is supported, as well as that...

Cytochrome b sequences of European leuciscins were employed to investigate phylogenetic relationships among species, using Bayesian inference, and to estimate times of diversi...
Article
Several characteristics of the Gobiesocidae, such as the fact that they are small cryptic fishes, could explain the scarcity of studies on these species when compared with other rocky littoral fish families. Analyses of molecular and meristic data are in agreement with the views of previous workers. The genus Lepadogaster must be redefined to inclu...

In their Editorial “Eaxonomy: impediment or expedient?”, Q. D. Wheeler et al. make a strong case for the internationalization of taxonomy through a cyber-infrastructure that would give taxonomists and museums access to the right tools for documenting species diversity (16 Jan., p. [285][1]).
Chapter
This chapter discusses coevolution, which is the joint evolution of two or more species or genomes, owing to interactions between them. These interactions include interspecific competition, mutualism, and interactions between consumers and victims, as well as other interactions such as mimicry. Quantitative genetic models of the evolution of compet...

The gap between evolutionary studies in laboratory versus natural populations is a persistent problem.
Article
Although inbreeding, on average, decreases additive genetic variance, some inbred populations may show an increase in phenotypic variance for some characters. In those populations with increased phenotypic variance, character changes by peak shifts may occur because of the effects of the higher variance on the adaptive landscape. A population's inc...

Project
MARE http://www.mare-centre.pt/en ISPA http://www.ispa.pt/ Kids Dive is an educational project that intends to bring ocean literacy to a wide audience of children (8-17 years old). What distinguishes this program from others is that it is performed by scientists and it is 100% practical, including a diving experience. The dive includes educational activities intrinsically related to two workshops presented in the same day: (1) "How to displastify the Ocean" raising questions and solutions on plastic pollution and (2) "Wonders of marine biodiversity" bringing augmented reality to explore the diversity of marine organisms. This educational program is further complemented by a second day visiting a local marine intertidal area, a third day in a guided visit and workshop in Lisbon Oceanarium and a forth day attending the National Geographic Summit, which started in Lisbon (Portugal) in 2017 with an enormous success. To wrap up, a short 5-10 min. documentary is produced for each project edition (60 children) so that they can share their experience with all their colleagues at school and families at home.

R&D Project of the FCT (Fundação para a Ciência e Tecnologia). Glacial refugia are often linked to the the persistence of different genetic lineages during Terciary or Quaternary climate fluctuations and thus of high genetic diversity and differentiation. Recent research proved that regional Mediterranean hotspots include an extremely high number of glacial refugia. Identification of refugia may be critical in spatial planning policies and conservation strategies, as they constitute significant reservoirs of threatened genetic diversity. Of the 52 plant refugia identified by Médail & Diadema (2009) for the Mediterranean bioclimatic region, 25 are included in three peninsulas: the Balkan, Iberian and Italian peninsulas. Among these, the Iberian Peninsula has the highest number of refugia (12). It is therefore an ideal place for studies on the issue of glacial refugia. In Portugal, three areas are considered putative refugia (Beira Litoral, Estremadura, Algarve), but other areas in mainland Portugal may have also as plant refugia, namely the Sado and coastal Alentejo regions. This project might prove the validity of these areas as refugia, particularly for turfophilous plants. We have identified in Portugal several peatland areas with isolated populations of species with temperate optimum, namely in Estremadura, along the mouth of the Sado River and along coastal Alentejo, which may constitute such refugia. To understand the paleobiogeographic effects of Quaternary climate changes, upon plant species occurring in a specific community, peat-rich environments, we will use a combination of different approaches: (1) morphological and phytosociological information, (2) paleobotanical and palynological information and (3) phylogeographic analyses, using genetic data, of several populations of four tufophilous species populations. This multiple approach will give us a comprehensive picture of the history of these environments, the relationship among southern peninsular refugia and Central European populations, and of the genetic diversity structure, population structure and gene flow among the populations of the four target species. We aim to answer several important questions: -- the characterization and location of glacial refugia of wetland species; - whether the Pyrenees played the role of a biogeographical barrier in the separation of genetically differentiated populations; - what migration routes were used by our studied peatland species, especially in SW Europe; - infer the consequences of Quartenary climate change upon European peatland communities; - and what are the future evolutive scenarios concerning recent and prospective climate changes.
