Trends in vegetation productivity and seasonality for Namaqualand, South Africa between 1986 and 2011: an approach combining remote sensing and repeat photography

open access: yes, 2013
This thesis presents an assessment of vegetation change and its drivers across a subset of Namaqualand, South Africa. Namaqualand forms part of the Succulent Karoo biome, which is characterised by exceptionally high species biodiversity but which has ...

Mapping Spatiotemporal Changes in Vegetation Growth Peak and the Response to Climate and Spring Phenology over Northeast China

open access: yes, 2020
Global climate change has led to significant changes in seasonal rhythm events of vegetation growth, such as spring onset and autumn senescence. Spatiotemporal shifts in these vegetation phenological metrics have been widely reported over the globe ...

Tetrataenium paikadae (Apiaceae), a new species from the Western Ghats, India

open access: yesNordic Journal of Botany, EarlyView.
A new species, Tetrataenium paikadae C.Rekha, Manudev & Prasanth (Apiaceae), is described from the State of Kerala, India. The new species is characterised by its hirsute to hispid stems, broadly ovate or rounded leaflets, long petioles with hirsute leaf sheaths, tomentose rays, symmetric flowers, ovate‐lanceolate involucel bracteoles, and mericarp ...

Cumulative and Lagged Effects of Drought on the Phenology of Different Vegetation Types in East Asia, 2001–2020

open access: yes
Drought disturbances are becoming more frequent with global warming. Accurately assessing the regulatory effect of drought on vegetation phenology is key to understanding terrestrial ecosystem response mechanisms in the context of climate change ...

Reinstatement and generic reassignment of Phyllanthus asteranthos Croizat (Phyllanthaceae) based on living plant observations and specimen analysis

open access: yesNordic Journal of Botany, EarlyView.
Phyllanthus asteranthos Croizat has been treated as a synonym of P. pulcher Wall. ex Müll. Arg. (syn. Nymphanthus glaucescens (Miq.) R.W.Bouman) since 1987. Through detailed morphological observations of living plants and critical examinations of type materials and additional specimens, this study revealed that the two taxa are morphologically very ...

Taxonomic identities of Coelogyne roseans, C. chen‐tsii and C. niana (Coelogyninae, Orchidaceae)

open access: yesNordic Journal of Botany, EarlyView.
The taxonomic identities of Coelogyne roseans (= Pholidota roseans) and C. niana (= P. niana) have long been misunderstood. Our findings indicate that C. chen‐tsii (= P. longipes) is conspecific with C. niana, consequentially C. chen‐tsii is reduced to a synonym of C. niana. Although C. roseans and C.

Shifts in vegetation phenology along flyways entail varying risks of mistiming in a migratory songbird [PDF]

open access: yes, 2016
Long-term shifts in vegetation phenology generally follow the pattern of global warming. Yet, topographical complexity and biome diversity cause uneven spatial trends in the phenological response of vegetation to climate change.

Breynia phuongiana (Phyllanthaceae), a new species from the Central Highlands of Vietnam

open access: yesNordic Journal of Botany, EarlyView.
A new species, Breynia phuongiana (Phyllanthaceae subgen. Sauropus), is described and illustrated from the Central Highlands of Vietnam. It is morphologically similar to B. beillei, B. bonii, and B. thorelii, but differs in having oblong‐elliptic leaves, sepals marked with reddish striations, an androphore exceeding 1 mm in length, and distinctly ...
