Portulaca abscondita (Portulacaceae, Caryophyllales), a new microendemic species from Monte Azul, Minas Gerais, Brazil

Nordic Journal of Botany, EarlyView.
Portulaca (Portulacaceae) is a cosmopolitan genus with centers of diversity in Africa and South America. In Brazil, 22 species are recognized, most occurring in xerophytic environments of the Cerrado, particularly in Campos Rupestres. These rocky montane habitats, especially in northern Minas Gerais state, remain undercollected despite their high ...

Sinningia pampeana sp. nov. (Gesneriaceae) from the Pampa's rocky outcrops in southern Brazil and Uruguay

Nordic Journal of Botany, EarlyView.
Sinningia pampeana is a new rupicolous species from the rocky outcrops of the Pampa biome in southern Brazil and Uruguay. Morphological analyses based on herbarium material, field observations, and detailed illustrations support its recognition as a distinct species from Sinningia sellovii.

Phenology and leaf adaptive strategies of Mediterranean maquis plants

Ecologia mediterranea, 1997
La dynamique des activités végétatives et reproductives a été comparée entre différentes espèces du maquis méditerranéen et leurs stratégies adaptatives ont été étudiées. Les espèces sclérophylles sempervirentes et semi-caduques montrent des différences dans le comportement phénologique et dans le développement des bourgeons et des feuilles.

Two new species of Calea ser. Multiplinerviae (Asteraceae: Neurolaeneae) from Brazil

Nordic Journal of Botany, EarlyView.
Detailed studies of specimens from Rondônia and Mato Grosso do Sul showed that two new species have been misidentified: Calea micropappa resembles Calea pilosa, but differs by leaf apex obtuse to acuminate (versus acute), paleae present (versus paleae absent), disc corolla lobes 1.2–1.3 mm long (versus 0.7–0.8 mm), and pappus scales 0.1–0.25 mm long ...

A new species and a synonym in Centaurea sect. Microlophus (Asteraceae, Cardueae–Centaureinae) from the Khuzestan Province, southwestern Iran

Nordic Journal of Botany, EarlyView.
A new species, Centaurea baghmalekensis Negaresh (Asteraceae) in C. sect. Microlophus (Cass.) DC., is described and illustrated from the Khuzestan Province, southwestern Iran. The new species is morphologically most similar to Centaurea pabotii Wagenitz, a recently described species from the Khuzestan Province.

Inequalities in intraspecific plant–lemur interactions drive seed dispersal patterns

Oikos, EarlyView.
Biotic interactions occur between individuals and accumulate to shape species‐level interaction structure across a community. Skewed interaction structures, where a few individuals are highly connected and most have few interactions, are increasingly identified at the individual‐level.

Divergence in Autumn Phenology Extracted From Different Satellite Proxies Reveals the Timetable of Leaf Senescence Over Deciduous Forests

Geophysical Research Letters
Remote sensing detection of autumn phenology is challenging and highly uncertain, as exemplified by the observed divergence in autumn phenology extracted from different proxies.
