Hacia una biogeografía evolutiva Towards an evolutionary biogeography

open access: yesRevista Chilena de Historia Natural, 2007
La proliferación de métodos en las últimas décadas ha llevado a algunos autores a cuestionar si la biogeografía es una disciplina coherente. Las biotas son mosaicos complejos debidos a dispersión (expansión de las distribuciones) y vicarianza ...

Analyzing Trends in Software Product Lines Evolution Using aCladistics Based Approach

open access: yesInformation, 2015
A software product line is a complex system the aim of which is to provide a platform dedicated to large reuse. It necessitates a great investment. Thus, its ability to cope with customers’ ever-changing requirements is among its key success factors ...

Genomic Variation and Population Structure of Portuguese Native Dog Breeds

open access: yesAnimal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT The presence of dogs in Portugal is confirmed by zooarchaeological evidence dating to at least 7600 years ago. The 11 native dog breeds that exist in this territory are therefore the end‐product of a complex evolutionary process. This study characterises the genomic diversity and population structure of 10 native breeds based on whole‐genome ...

Revision and phylogenetic analysis of the subfamily Platerodinae (Coleoptera: Lycidae)

open access: yesEuropean Journal of Entomology, 2001
Genus-group taxa of Platerodinae are revised and valid taxa are redescribed. The validity of Plateros Bourgeois, 1879 is reinstated. Libnetomimus Kleine, 1927 is made a junior synonym of Libnetis Waterhouse, 1878. Calleros Gorham, 1881, Calloplateros Pic,

Early evolutionary history of the seed

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Hypothetico-deductivism in systematics: fact or fiction?

open access: yesPapéis Avulsos de Zoologia, 2008
Phylogenetic systematics (the cladistic analysis of phylogenetic relationships) is not hypotheticodeductively structured (in the sense of a covering law model of scientific explanation).

Multiple Reassortments, Limited Geographic Spread, and Comparable Pathogenicity of Crimean‐Congo Hemorrhagic Fever Viruses in Sivas Province, Türkiye

open access: yesJournal of Medical Virology, Volume 98, Issue 6, June 2026.
ABSTRACT Crimean‐Congo hemorrhagic fever virus (CCHFV) is a segmented RNA virus that can cause severe hemorrhagic fever and is primarily transmitted to humans and other mammals through tick bites. Since segment reassortment can increase genetic diversity and disease severity, we sampled infected ticks and humans in Sivas Province, Türkiye, a region ...

Phylogenetic position and redescription of Orchestina manicata Simon, 1893 (Araneae: Oonopidae) [PDF]

open access: yesJournal of Insect Biodiversity and Systematics
The goblin spider Orchestina manicata Simon, 1893 (Araneae: Oonopidae) has remained taxonomically unrevised and has not been phylogenetically placed until now. In this study, O.

Phylogenetic analysis and the recognition of a new genus for Mexican Crassulaceae segregated from Echeveria

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract Systematic knowledge of the Mexican Crassulaceae is slowly progressing as data from new DNA regions and species sampling efforts increase. We compiled and generated new rbcL, matK, rps16, ITS/ITS2, and ETS DNA sequences and performed an updated phylogenetic reconstruction for a group of 131 Mexican Crassulaceae terminals from 11 of the 13 ...
