Linear trends in seasonal vegetation time series and the modifiable temporal unit problem [PDF]

, 2012
Time series of vegetation indices (VI) derived from satellite imagery provide a consistent monitoring system for terrestrial plant productivity. They enable detection and quantification of gradual changes within the time frame covered, which are of ...

Historical data reveal earlier flowering under environmental change

Nordic Journal of Botany, EarlyView.
Global temperatures have risen ~ 1.1°C since the 1800s and the mean annual air temperature in the Arctic has increased by nearly four times the global average. Temperature has a significant effect on fundamental life‐cycle events of flora and fauna. With temperatures increasing, Arctic plants are expected to shift their active periods accordingly, with

DeepPhenoMem V1.0: deep learning modelling of canopy greenness dynamics accounting for multi-variate meteorological memory effects on vegetation phenology [PDF]

Geoscientific Model Development
Vegetation phenology plays a key role in controlling the seasonality of ecosystem processes that modulate carbon, water and energy fluxes between the biosphere and atmosphere. Accurate modelling of vegetation phenology in the interplay of Earth's surface

Bauhinia naniflora: a new species of section Amaria (Cercidoideae: Leguminosae) from Colombia

Nordic Journal of Botany, EarlyView.
Bauhinia, the most species‐rich genus of Cercidoideae (Leguminosae), is pantropically distributed and includes four sections in the Americas. During an ongoing taxonomic revision of American Cercidoideae, a new species of Bauhinia sect. Amaria ser. Decandrae currently endemic to Colombia was identified and is here described as Bauhinia naniflorasp nov.

Two new endemic species of Portulaca (Portulacaceae) from the Brazilian Pampa grasslands

Nordic Journal of Botany, EarlyView.
Portulaca L. is a monophyletic, cosmopolitan genus of succulent plants comprising ca 153 species, with particularly high diversity in xerophytic ecosystems in tropical and subtropical regions. Based on morphological evidence, we describe and illustrate two new species from the Brazilian Pampa, Portulaca guaritensis and Portulaca guenoa.

Understanding vegetation phenology responses to easily ignored climate factors in china's mid-high latitudes

Scientific Reports
Previous studies have primarily focused on the influence of temperature and precipitation on phenology. It is unclear if the easily ignored climate factors with drivers of vegetation growth can effect on vegetation phenology.

Barbacenia pendula sp. nov.(Velloziaceae) from the northern Espinhaço Range of Minas Gerais, Brazil

Nordic Journal of Botany, EarlyView.
Although botanical exploration in the Espinhaço Range has increased in recent years, several areas remain poorly sampled, particularly in northern Minas Gerais. Recently, this area has been receiving scientific expeditions, leading to the description of several new plant species.
