This study investigated the ecology, diversity and seasonal distribution of wild mushrooms at Environmental Pollution Science and Technology (ENPOST) forest reserve, Ilesa, Southwestern Nigeria. Mushrooms growing in the ligneous and terrestrial habitats of the forest were collected, identified and enumerated between March 2014 and March 2015. Diversity indices including species richness, dominance, and species diversity were eva

Abstract:
In this article nine alien woody species within the Danube Delta were evaluated, from the perspective of certain population indices. The frequency and the abundance and the calculation of ecological significance index of these species were taken into account, both in fluvial and fluvial-maritime delta. Five zones of investigation were chosen so that they should comprise all the natural features of the Danube Delta. Within these areas, several vegetation units are included, as follows: ontea-Fortuna, natural lake complex with reed beds, forests liable to flooding and meadows; Mati a-Merhei lake

Abstract:
In many tropical countries, woody forage plays an important role in ruminant nutrition. Five woody species commonly used in south-eastern Mali were subjected to a preference test, in order to examine their potential of being included in the rations of stall-fed sheep. A complete randomised block (Latin square) experiment with four rams was carried out during two test periods of five days each to test the appreciation of fresh and dried leaves, respectively, of the five species. On each test day, the five species were offered concomitantly to the rams for 30 min in the morning, and the paramete

Abstract:
The objective of this research was to investigate the effect of seasonality on the chemical composition and concentration of phenolic compounds in some ligneous species. The research was conducted at the Aristotle University’s farm, Thessaloniki, Greece. From five ligneous species (Robinia pseudoacacia var. monophylla, Amorpha fruticosa, Colutea arborescens, Morus alba and Arbutus unedo) samples (leaves and twigs) were collected during two different seasons (spring and autumn). All samples were analyzed for crude protein (CP), Neutral Detergent Fiber (NDF), Acid Detergent Lignin (ADL) and in v

Abstract:
Early post-fire structural dynamics in three Quercus pyrenaica communities after intense fires was studied. In the first year there is a marked domination of perennial species (herbaceous or woody); afterwards, herbaceous species tend to decrease in importance and ligneous species increase. Changes in species diversity were analysed as an indicator of recovery and stability in the communities. An increase was observed in the second year, and then diversity was maintained or reduced slightly in the third and fourth years. Spatial heterogeneity tends to diminish with time.

Abstract:
A new species, Ticanto xylocarpa K. W. Jiang & Shi J. Li is described and illustrated here. It is superficially similar to T. magnifoliolata in its leaf shape and ferruginous young branches and inflorescence axes. However, it is readily distinguished by the ligneous and wingless pods that are dehiscent when mature. Calculations of Area of Occupancy (AOO) and Extent of Occurrence (EOO) suggest that Ticanto xylocarpa meets the criteria for Least Concern (LC) in the IUCN Red List.

Abstract:
The present study was carried out to explore the plant diversity in the famous Santala Devi Sacred Grove, situated on the outskirts of Dehradun city in Uttarakhand state. A total of 103 plant species belonging to 90 genera under 46 families were documented. The study centered only on the diversity of ligneous (woody) species in the forest. The recorded plant species have been presented based on their scientific and vernacular names, family habit and their uses. Moreover, the ecological importance of plants and their conservation needs have been also discussed in this paper.

Abstract:
A preliminary non-exhaustive study was conducted on the ignition of some ligneous biomass pellets inside a laboratory scale traveling bed furnace. The experiments consisted in the measurement of the ignition time of volatiles released by six different types of pellets, obtained from wood species found in the Portuguese forest, namely Pinus pinaster, Acacia dealbata, Cytisus scoparius, Cistus ladanifer, Paulownia cotevisa and Eucalyptus globulus. The experiments were carried out at corrected furnace temperatures of 359, 381, 403, 424 and 443 °C, using two different pellet sizes and with batches

Abstract:
ABSTRACT Permanent preservation areas (PPAs) adjacent to drainage channels may include forests, savannahs, or grassland Under a former environmental legislation ("Forest Code"), it was required to maintain a strip of native vegetation (at least 30 m wide) at the margin of any drainage channel, to support environmental functions. Under the current native vegetation protection policy, if a riparian margin was degraded prior to 2008, the landholder is required to regenerate a strip of only 5-20 m, in some cases.

There are two types of electric crossing : i ) subterranean / submarine line ii ) overhead-line crossing. We always consider the last one as a more economic option. The inconvenience of an overhead-line crossing would be the environmental constraints among which the existing obstacles, the clearance for the navigation and the aesthetics demanded by the public. The overhead-line crossings usually have conductors of long ranges which are outside of the field of application for the current transmission line codes. These are limited to reaches of a length included between 200 m and 800 m, as well

Les infrastructures linéaires sont reconnues pour faciliter la dispersion de plantes indésirables dans leur emprise et les habitats adjacents. Toutefois, les impacts des emprises de lignes électriques ont été peu étudiés, particulièrement en milieux humides. Cette étude a examiné la végétation des emprises de lignes électriques et de leurs habitats adjacents dans 23 tourbières ombrotrophes (bogs) et 11 minérotrophes (fens). Dans les fens, la dispersion des espèces indésirables est facilitée le long des emprises et certaines espèces peuvent se propager à plus de 43 m dans les habitats adjacents
