Clarifying the identity of Helichrysum sordidum (Compositae): typification and proposal of a replacement name

Carme Blanco‐Gavaldà, Genís Puig-Surroca, Mercè Galbany‐Casals, Santiago Andrés‐Sánchez

A replacement name, Helichrysum kintamalandy C.B.Gavaldà & Puig-Surroca, is proposed for H. sordidum Humbert [1923], an endemic species from the Tsaratanana Massif in northern Madagascar. The latter name is illegitimate because it is a later homonym of H. sordidum S.Moore [1906], a …

Climate change vulnerability of the Afrotemperate flora on Africa’s tropical sky islands

Elvira Castillo-Almansa, Rubén G. Mateo, Mercè Galbany‐Casals, Carme Blanco‐Gavaldà et autres

Abstract Climate change poses a significant threat to the Afrotemperate flora of the Eastern Afromontane Biodiversity Hotspot, particularly to species confined to high-elevation ecosystems such as those found on the African sky islands. This study evaluates the vulnerability of tropical Afroalpine and …

Hidden lineages in the African Sky Islands: A taxonomic reevaluation of Afrocarduus (Compositae)

Lucía D. Moreyra, Juan Antonio Calleja, Cristina Roquet, Siri Birkeland et autres

Abstract Accurate species delimitation is crucial for biodiversity research, as it significantly impacts taxonomy, ecology, and conservation. Recent advances in molecular phylogenetics and integrative taxonomy have improved classifications and resolved long‐standing taxonomic uncertainties. Here, we use Hyb‐Seq (489 nuclear loci) and phylogenomic …

From Pleistocene Corridors to Isolated Peaks and Back: Biogeography of Afrocarduus (Compositae) in the Afromontane Archipelago

Lucía D. Moreyra, Cristina Roquet, Alfonso Susanna, Siri Birkeland et autres

ABSTRACT Aim We investigated the biogeographic history and diversification dynamics of Afrocarduus , an Afromontane–Afroalpine genus endemic to eastern Africa. We aimed to assess the roles of geographic isolation, habitat transitions, and ecological speciation in shaping current diversity. Location The Afromontane and …

Climatic oscillations, dispersibility and adaptability behind worldwide mountain radiations of the Helichrysum–Anaphalis–Pseudognaphalium (HAP) clade (Compositae)

Carme Blanco‐Gavaldà, Renske E. Onstein, Luís Valente, Thijs Janzen et autres

BACKGROUND AND AIMS: Mountain ecosystems are recognised as biodiversity hotspots. However, the origins of their remarkable diversity remain unresolved. We explore this question by focusing on the HAP clade (Helichrysum-Anaphalis-Pseudognaphalium), a megadiverse lineage within the Compositae family that spans tropical and temperate …

A thorny tale: The origin and diversification of Cirsium (Compositae)

Lucía D. Moreyra, Alfonso Susanna, Juan Antonio Calleja, Jennifer R. Ackerfield et autres

Widely distributed plant genera offer insights into biogeographic processes and biodiversity. The Carduus-Cirsium group, with over 600 species in eight genera, is diverse across the Holarctic regions, especially in the Mediterranean Basin, Southwest Asia, Japan, and North America. Despite this diversity, evolutionary …

Biome conservatism prevailed in repeated long-distance colonization of Madagascar’s mountains by Helichrysum (Compositae, Gnaphalieae)

Carme Blanco‐Gavaldà, Cristina Roquet, Genís Puig-Surroca, Santiago Andrés‐Sánchez et autres

Colonization and diversification processes are responsible for the distinctiveness of island biotas, with Madagascar standing out as abiodiversity hotspot exceptionally rich in species and endemism. Regardless of its significance, the evolutionary history and diversification drivers of Madagascar's flora remain understudied. Here we …

African Mountain Thistles: Three New Genera in the Carduus-Cirsium Group

Lucía D. Moreyra, Núria Garcia‐Jacas, Cristina Roquet, Jennifer R. Ackerfield et autres

The floras on the highest mountains in tropical eastern Africa are among the most unique floras in the world. Despite the exceptionally high concentration of endemic species, these floras remain understudied from an evolutionary point of view. In this study, we focus …

Repeatedly Northwards and Upwards: Southern African Grasslands Fuel the Colonization of the African Sky Islands in Helichrysum (Compositae)

Carme Blanco‐Gavaldà, Mercè Galbany‐Casals, Alfonso Susanna, Santiago Andrés‐Sánchez et autres

The Afromontane and Afroalpine areas constitute some of the main biodiversity hotspots of Africa. They are particularly rich in plant endemics, but the biogeographic origins and evolutionary processes leading to this outstanding diversity are poorly understood. We performed phylogenomic and biogeographic analyses …
