Dataset of male and female reproductive success in the forest tree species Abies alba Mill.
No full textSilver fir (Abies alba Mill.) is a shade tolerant European conifer, distributed across temperate mountain areas (e.g. in France: Pyrenees, Massif Central, Alps, Jura, Vosges, Montagne de l'Aigle), at moderate elevations between 300 and 1800 meters above sea level. This monoecious, wind-pollinated species is self-compatible and has a mixed mating system, although it passively avoids self-fertilization (geitonogamy): female strobili (i.e. cones) are located within the top third of the crown, whereas male strobili (catkins) are located within the bottom two thirds of the crown.
The dataset includes male and female reproductive yield (pollen and cone production), tree location, tree density, height, circumference and crown shape, quality of seeds (filled versus empty seeds and selfing rate), and seed weight of 148 silver fir trees from two marginal mountains in the south-eastern French Alps, Ventoux and Lure, monitored over a period of four years (2002-2005). This period includes year 2003, characterized by an intense summer heat wave in that part of France. The data also include selfing rate calculated using genotyping of chloroplast DNA (microsatellites) as explained in the PhD thesis of G. Restoux (2009). The data can be used to test the effect of environmental drivers on selfing and female reproductive success and shed light on the evolution of mixed mating in plants.
The data are in file "Data_selfing" and the description of the dataset contents is in file "MetaData_Selfing_En" for the English version of the metadata and in file "MetaData_Selfing_Fr" for the French version.<br
Single-nucleotide polymorphism (SNP) data for 1,085 adult individuals from 54 range-wide populations of 5 European conifer species
No full textGeneral description
This dataset contains the Single Primer Enrichment Technology (SPET) data (variant call format -vcf- files) of five conifer species used in the manuscript "Genome-wide data to assist conservation in five European conifer species". The SNPs were selected based on DNA regions containing loci with a known adaptive function or putatively under selection, sequences of orthologous gene families with functions of interest, and genes with unknown functions and presumably neutral loci.
For each species, between 161 and 371 genotyped trees are included, sampled across their European range in 9 to 15 locations. Three different datasets are provided for each species: (1) target SNPs (TARGET), (2) de novo SNPs - detected within 100 base pair (bp) distance from each targeted SNP (DENOVO) and (3) target and de novo SNPs combined (COMBINED), resulting in three vcf files per species, built as [species tag]_v5.2.2.1_[TARGET/DENOVO/COMBINED].vcf.gz. The vcf files can be opened and analyzed using the following custom-made pipeline: https://github.com/amfarsakoglou/GenTree_SPET_Pipeline_short_version.
The file "GenTree consortium" lists all authors involved in DNA sampling and extraction.
Species included: Abies alba Mill. (tag: AA), Pinus cembra L.(tag: PC), Pinus halepensis Mill.(tag: PH), Pinus nigra J.F.Arnold (tag: PN), and Taxus baccata L. (tag: TB)</p
Phenotypic trait dataset of Pinus pinea from five common gardens of the INRAE GEN4X network
No full textDonnées sur les traits phénotypiques de Pinus pinea mesurés dans les jardins communs du réseau INRAE de génétique forestière pour la recherche et l'expérimentation (GEN4X).
Ce jeu de données est composé d'observations telles que la hauteur totale, la circonférence, le nombre de cônes, la survie et la fourchaison, réalisées jusqu'en 2012 dans cinq tests de provenance de Pinus pinea du réseau français de jardins communs GEN4X (réseau de génétique forestière pour la recherche et l'expérimentation). Il permet de comparer jusqu'à 40 unités génétiques différentes (provenances) de Pinus pinea plantées dans des conditions environnementales variées du sud de la France et d'obtenir des informations sur la plasticité phénotypique et la diversité génétique de ces caractères phénotypiques.
Les jardins communs ont été plantés entre 1993 et 1995 et contiennent plus de 5000 individus.
L'archive contient sept fichiers. Le fichier "Description provenances archive" contient les métadonnées sur les provenances. Le fichier "Description Jardins communs archive" contient les métadonnées sur les sites de plantation. Chacun des cinq fichiers restants contient les données phénotypiques, un fichier par jardin commun.

This dataset is composed of observations such as height, circumference, cone number, survival and forking, made from 1994 to 2022 in five Pinus pinea provenance trials of the French common gardens network GEN4X (forest genetics network for research and experimentation). The dataset makes possible the comparison of up to 40 different Pinus pinea genetic units (provenances) planted under varied environmental conditions in southern France and to inform on the phenotypic plasticity and genetic diversity of the phenotypic traits measured.
The common gardens were planted between 1993 and 1995 and include between 1770 and over 5000 individuals..
The archive contains seven files:
File "Description provenances archive" contains metadata on provenances
File "Description Jardins communs archive" contains metadata on test sites
Each of the remaining files contain the data themselves, one per common garden. Variable metadata are included in these files, as first rows of each file.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Forests and global change what can genetics contribute to the major forest management and policy challenges of the twenty-first century?
No full textThe conservation and sustainable use of forests in the twenty-first century pose huge challenges for forest management and policy. Society demands that forests provide a wide range of ecosystem services, from timber products, raw materials and renewable energy to sociocultural amenities and habitats for nature conservation. Innovative management and policy approaches need to be developed to meet these often-conflicting demands in a context of environmental change of uncertain magnitude and scale. Genetic diversity is a key component of resilience and adaptability. Overall, forest tree populations are genetically very diverse, conferring them an enormous potential for genetic adaptation via the processes of gene flow and natural selection. Here, we review the main challenges facing our forests in the coming century and focus on how recent progress in genetics can contribute to the development of appropriate practical actions that forest managers and policy makers can adopt to promote forest resilience to climate change. Emerging knowledge will inform and clarify current controversies relating to the choice of appropriate genetic resources for planting, the effect of silvicultural systems and stand tending on adaptive potential and the best ways to harness genetic diversity in breeding and conservation programs. Gaps in our knowledge remain, and we identify where additional information is needed (e.g.;the adaptive value of peripheral populations or the genetic determinism of key adaptive traits) and the types of studies that are required to provide this key understanding. © 2015, Springer-Verlag Berlin Heidelberg
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
