Alien plants in urban nature reserves : from red-list species to future invaders? [PDF]

open access: yes, 2011
Urban reserves, like other protected areas, aim to preserve species richness but conservation efforts in these protected areas are complicated by high proportions of alien species.

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population

open access: yesPopulation Ecology, EarlyView.
This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

Studies on the behavior of some cultivars of Dahlia in the Botanical Garden Cluj-Napoca

open access: yesRomanian Journal of Horticulture
Dahlias are particularly appreciated due to the elegance of the inflorescences and the long duration of flowering, which gives them multiple uses both in floral art and in landscaping.

Stable equatorial ice belts at high obliquity in a coupled atmosphere-ocean model [PDF]

open access: yesApJ, Year 2018, Volume 864, Number 2, Page 106, 2018
Various climate states at high obliquity are realized for a range of stellar irradiance using a dynamical atmosphere-ocean-sea ice climate model in an Aquaplanet configuration. Three stable climate states are obtained that differ in the extent of the sea ice cover.

Nodulation in Onobrychis Perennial Legume Plants [PDF]

open access: yesAmerican Journal of Plant Sciences, 2010
A total of 110 strains of nodule bacteria was isolated from plants Onobrychis transcaucasica and Onobrychis chorassanica. Nodulation study of bacteria in both Onobrychis plant species in microvegetation experiment gave a very low nodulation on plant roots.

Orthology guided transcriptome assembly of Italian ryegrass and meadow fescue for single-nucleotide polymorphism discovery [PDF]

open access: yes, 2016
Single-nucleotide polymorphisms (SNPs) represent natural DNA sequence variation. They can be used for various applications including the construction of high-density genetic maps, analysis of genetic variability, genome-wide association studies, and ...

Electricity Generation From Ambient Water Evaporation in the Absence of Sunlight via PVA‐Based Porous Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
In this article, a water‐evaporation driven energy harvester is devised that works even in the absence of sunlight. This is achieved by combining PVA hydrogel with thermoelectrics (TEG) to directly capture energy from water evaporation. Under mild conditions (RH 40%, T of 26 °C, and 2.8 m s−1 wind), 1.71 mW (1.02 W m−2) power can be generated, >3 fold ...

Perennials and the Group-Theoretical Quantization of a Parametrized Scalar Field on a Curved Background [PDF]

open access: yesJ.Math.Phys. 37 (1996) 3522-3538, 1995
The perennial formalism is applied to the real, massive Klein-Gordon field on a globally-hyperbolic background space-time with compact Cauchy hypersurfaces. The parametrized form of this system is taken over from the accompanying paper. Two different algebras ${\cal S}_{\text{can}}$ and ${\cal S}_{\text{loc}}$ of elementary perennials are constructed ...

Combined genetic, genomic and physiological approaches to characterize flowering in Fragaria [W324] [PDF]

open access: yes, 2015
Flowering is a key event for production of seeds or fruits. To date, studies of this process were mainly focused on the molecular mechanisms involved in the control of flowering until now.
