1. Adjustment to the light environment in small-statured forbs as a strategy for complementary resource use in mixtures of grassland species

Author:
Roscher, Christiane; Kutsch, Werner L.; Kolle, Olaf; Ziegler, Waldemar; Schulze, Ernst-Detlef

Annals of botany 2011 v.107 no.6 pp. 965-979
ISSN:

Subject:
biodiversity; biomass; canopy; carbon; forbs; grasslands; ground vegetation; leaves; metabolism; niches; photophase; plant communities; transmittance
Abstract:
... BACKGROUND AND AIMS: The biological mechanisms of niche complementarity allowing for a stable coexistence of a large number of species in a plant community are still poorly understood. This study investigated how small-statured forbs use environmental niches in light and CO₂ to explain their persistence in diverse temperate grasslands. METHODS: Light and CO₂ profiles and the corresponding leaf cha ...

Subject:
Caryophyllaceae; alpine plants; altitude; biodiversity; ecosystems; keystone species; plant ecology; prediction; rain
Abstract:
... BACKGROUND: Cushion plants are commonly considered as keystone nurse species that ameliorate the harsh conditions they inhabit in alpine ecosystems, thus facilitating other species and increasing alpine plant biodiversity. A literature search resulted in 25 key studies showing overwhelming facilitative effects of different cushion plants and hypothesizing greater facilitation with increased enviro ...

3. Nuclear DNA amounts in angiosperms: targets, trends and tomorrow

Author:
Bennett, M.D.; Leitch, I.J.

Annals of botany 2011 v.107 no.3 pp. 467-590
ISSN:
0305-7364
Subject:
sequence analysis; parasitic plants; buffers; plant architecture; chromosome number; DNA; biodiversity; flow cytometry; nuclear genome; flora; Angiospermae; databases
Abstract:
... BACKGROUND AND AIMS: The amount of DNA in an unreplicated gametic chromosome complement is known as the C-value and is a key biodiversity character of fundamental significance with many practical and predictive uses. Since 1976, Bennett and colleagues have assembled eight compilations of angiosperm C-values for reference purposes and subsequently these have been pooled into the Angiosperm DNA C-va ...

Abstract:
... BACKGROUND: Carnivorous pitcher plants (CPPs) use cone-shaped leaves to trap animals for nutrient supply but are not able to kill all intruders of their traps. Numerous species, ranging from bacteria to vertrebrates, survive and propagate in the otherwise deadly traps. This paper reviews the literature on phytotelmata of CPPs. PITCHER FLUID AS A HABITAT: The volumes of pitchers range from 0·2 mL t ...
