Continuos g-contraíbles

Revista Integración, 2012
Diremos que un continuo X es g-contraíble si existe una función continua y sobreyectiva f : X → X que es homotópica a una función constante. En este artículo hacemos una recopilación de los resultados conocidos acerca de los continuos g-contraíbles ...

Molecular phylogenetics of Thymelaeaceae‐Thymelaeoideae: Resolving the paraphyly of Gnidia and a new monophyletic generic classification for the group

TAXON, Volume 75, Issue 4, August 2026.
Abstract Earlier phylogenetic analyses of the family Thymelaeaceae using combined plastid (matK, rbcL, rps16, trnL‐F) and nuclear (ITS) regions showed that the African‐Malagasy genus Gnidia was extensively polyphyletic in relation to the southern African genera Lachnaea, Passerina and Struthiola, as well as to other Southern Hemisphere genera such as ...

All pieces together now? A phylogenomic analysis and tribe‐level classification of the heterogeneous family Plantaginaceae

TAXON, Volume 75, Issue 4, August 2026.
Abstract The plant family Plantaginaceae comprises approximately 2100 species in 106 genera, representing around 1% of all eudicots. The current circumscription of the family has been established in recent decades based on insights from DNA‐based phylogenetic analyses, which have united genera previously considered unrelated.

Ceramic Production and Geodiversity in Iron Age Iberia: An Archaeometric Study of Pottery from Castrejón de Capote (SW Spain)

Archaeometry, Volume 68, Issue 4, Page 659-673, August 2026.
ABSTRACT The hillfort of Castrejón de Capote is one of the best investigated settlements of Late Iron Age southwest Iberia. Located in the territory that the classical sources attributed to the Celtici, it was occupied between the early 4th and the 1st centuries bce.

Cross‐Linguistic Variations in Word‐Final Position: The Parametric Hierarchies, Connections and Networks

Studia Linguistica, Volume 80, Issue 2, August 2026.
ABSTRACT Word‐final position is widely recognized as a structurally weak and restricted domain, yet languages differ strikingly in how they regulate segments and clusters at the right edge. While some systems categorically prohibit final consonants, others allow only a subset of segments, and still others impose process‐based adjustments such as final ...

Coral reef and mangrove interplay during Holocene sea level changes, Belitung Island, Indonesia

Earth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.
The fate of mangroves and coral reefs during the ongoing sea level rise depends not only on our ability to preserve the ecosystems but also on their geological preconditioning. Therefore, strategies to preserve mangrove ecosystems, while undoubtedly essential, wecan only be successful if accounting for their geological history. Abstract Coral reefs and

Tensor Products of Dendroidal Sets

, 2022
AbstractIn the first chapter we described the Boardman–Vogt tensor product of two operads. This operadic tensor product induces a related tensor product on dendroidal sets by the method of Kan extension. This new dendroidal tensor product agrees with the Cartesian product when restricted to simplicial sets, and reproduces the Boardman– Vogt tensor ...

The dendroidal category is a test category [PDF]

Mathematical Proceedings of the Cambridge Philosophical Society, 2018
AbstractWe prove that the category of trees Ω is a test category in the sense of Grothendieck. This implies that the category of dendroidal sets is endowed with the structure of a model category Quillen-equivalent to spaces. We show that this model category structure, up to a change of cofibrations, can be obtained as an explicit left Bousfield ...

Calyx and epicalyx morphology in Indian Hibiscus (Malvaceae) and its taxonomic importance

Nordic Journal of Botany, Volume 2026, Issue 7, July 2026.
Hibisceae is one of the largest tribes in Malvaceae, having a diverse floral morphology. The genus Hibiscus shows a wide range of evolutionary patterns in calyx and epicalyx morphology. Genera like Abelmoschus, Azanza, Gossypium, Hibiscus,and Thespesia are separated on the basis of calyx and epicalyx morphology, meaning that the calyx and epicalyx have

Contrasting Forest Trajectories Drive Changes in Bird Functional Traits

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim We investigated how bird functional diversity varies across forest habitat types with distinct successional trajectories, namely (1) natural succession forests, with naturally regenerating forests established on former grasslands; (2) secondary forest remnants resulting from deforestation; and (3) conserved forests.
