Vitex oreadica and V. umbellata (Lamiaceae): two new species from Cerrado and Atlantic forest of Brazil

Nordic Journal of Botany, EarlyView.
Vitex L. is a pantropical genus of Lamiaceae comprising 209 taxa. Brazil harbors 35 species, representing nearly 50% of the genus richness in the Neotropics, with the Amazon showing the highest richness, followed by the Atlantic Forest and Cerrado domains. Nevertheless, most taxonomic studies of the genus have been conducted in Africa and Asia.

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.

Meyna grisea (King & Gamble) Robyns and Meyna peltata Robyns (Rubiaceae: Vanguerieae) – a new record of two ethnobotanically significant fruit trees from Manipur, India

Nordic Journal of Botany, EarlyView.
Meyna grisea and M. peltata, two new records from Imphal Valley, Manipur, India, characterised by a capitate stigma with 4–5 divergent, spreading lobes on a globose base, and a prominent peltate stigma, respectively, are described and illustrated here. Photographs, key to the species, along with their coordinates and diagnostic characters in comparison

Leaf phenology : from physiology to global change

, 2016
The timing and duration of leaf deployment strongly regulate earth-atmosphere interactions and biotic processes. Leaf dynamics therefore have major implications for life on earth, including the global energy balance, carbon and water cycles, feedbacks to

Additions to the Acanthaceae of the Flora of Tropical East Africa: two new species from northern Kenya

Nordic Journal of Botany, EarlyView.
The new species Barleria kulalensis I.Darbysh. & Q.Luke and Dicliptera huriensis I.Darbysh. & Q.Luke are described and illustrated and their extinction risk is assessed provisionally. The former is based on Barleria sp. G of the Flora of Tropical East Africa (FTEA), with recent field observation and collection of this species from the foothills of ...

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.

From field to globe: upscaling of crop growth modelling

, 2011
Recently, the scale of interest for application of crop growth models has extended to the region or even globe with time frames of 50-100 years. The application at larger scales of a crop growth model originally developed for a small scale without any ...

Reestablishment and a new name for Actinostemon grandifolius (Müll.Arg.) Pax

Nordic Journal of Botany, EarlyView.
The genus Actinostemon has undergone several changes in its circumscription due to persistent difficulties in its taxonomic placement. The taxonomic history of the genus is controversial and marked by nomenclatural issues, particularly involving its type species, Actinostemon grandifolius Klotzsch, including incorrect synonymizations and the ...

Solar Radiation Triggers the Bimodal Leaf Phenology of Central African Evergreen Broadleaved Forests

Journal of Advances in Modeling Earth Systems
Central African evergreen broadleaved forests around the equator exhibit a double annual cycle for canopy phenology and carbon uptake seasonality. The underlying drivers of this behavior are poorly understood and the double seasonality is not captured by

Validation and application of the MERIS Terrestrial Chlorophyll Index.

Climate is one of the key variables driving ecosystems at local to global scales. How and to what extent vegetation responds to climate variability is a challenging topic for global change analysis.
