A sensitivity study of daytime net radiation during snowmelt to forest canopy and atmospheric conditions [PDF]

, 2004
This study investigates the dependence of net radiation at snow surfaces under forest canopies on the overlying canopy density. The daily sum of positive values of net radiation is used as an index of the snowmelt rate.

Novelty for the flora of Espírito Santo, Brazil: a new species of Ouratea Aubl. (Ochnaceae)

Nordic Journal of Botany, EarlyView.
Here, we describe and illustrate the new species Ouratea oberdanii Fraga & Deccache, which is named after Dr Oberdan José Pereira. This new species is found in the mountainous regions of the evergreen Atlantic Forest in the Brazilian state of Espírito Santo. Ouratea oberdanii is similar to O. linearis (A.Gray) Sastre & Offroy and O.

Analysis of vertical differentiation of vegetation in Taishan World Heritage site based on cloud model

Scientific Reports
While the forests on Mount Taishan are predominantly man-made, there is a notable vertical variation in vegetation. This study employs the method of cloud model, quantifying uncertainty (fuzziness and randomness) of things.

High functional diversity is related to high nitrogen availability in a deciduous forest - evidence from a functional trait approach

, 2010
The current study tested the assumption that floristic and functional diversity patterns are negatively related to soil nitrogen content. We analyzed 20 plots with soil N-contents ranging from 0.63% to 1.06% in a deciduous forest near Munich (Germany ...

Cybianthus anthuriophyllus (Primulaceae), a new record for the flora of Colombia: distribution modeling and conservation assessment

Nordic Journal of Botany, EarlyView.
Cybianthus anthuriophyllus (Primulaceae) was previously known from eastern Ecuador and northern Peru. Here we document the first confirmed occurrences of this species in Colombia and develop a distribution model based on collections from the Andean–Amazonian foothills of Caquetá, Cauca, and Putumayo departments, in order to clarify its conservation ...

A new combination in Strophopappus (Asteraceae, Vernonieae, Lepidaploinae)

Nordic Journal of Botany, EarlyView.
Revisions of herbarium collections reveal a new combination in Strophopappus (Asteraceae, Vernonieae, Lepidaploinae). Strophopappus comprises nine species occurring in South America, eight of which are endemic to Brazil. Currently, Vernonia riedeliana is treated as a synonym of Strophopappus bicolor.

Drivers of individual plant species contributions to β‐diversity are scale‐dependent

Oikos, EarlyView.
Species introductions and local extinctions of native species are driving biotic homogenisation in plant communities by reducing β‐diversity. Individual species vary in their contributions to β‐diversity (species contribution to β‐diversity; species‐β), yet our understanding of how species characteristics shape these contributions remains limited ...

Functional Traits of Trees From Dry Deciduous “Forests” of Southern India Suggest Seasonal Drought and Fire Are Important Drivers

Frontiers in Ecology and Evolution, 2019
Two dominant biomes that occur across the southern Indian peninsula are dry deciduous “forests” and evergreen forests, with the former occurring in drier regions and the latter in wetter regions, sometimes in close proximity to each other.

PRAIRIE INCLUSIONS IN THE DECIDUOUS FOREST CLIMAX

American Journal of Botany, 1922
In the deciduous forest of the central states small fragments of prairie frequently occur (see fig. I). These vary in area from a few square feet to several acres, occurring usually on hillsides exposed to the south, southeast, or southwest. Shimek (5, 6, 7) has noted them in northwestern Iowa and along the Missouri River; Pammel, MacDonald, and Clark (
