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

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

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.

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.

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.

The aim of this research is to analyze the socio-cultural importance of non-ligneous forest products (NWFPs) in the forest of Agoua, located in the department of Hills in Benin. This research led to an inventory of NWFPs and ethnobotanical surveys among 50 foresters, 62 NWFP resellers, 46 consumers and 12 phytotherapists. The data collected relate to the plant species used as NWFPs by populations living on the massif of Agoua, to endogenous knowledge and to the use values of NWFPs. Thus, 105 plant species distributed in 48 families have been inventoried within the forest massif of Agoua. The d

Unlike other countries in the region, Cameroon is already experiencing very significant pressure on land, not only due to demographic factors but also related to the development of economic activities. This study focuses on the characterization of ligneous species in the Mbalmayo forest reserve. Trees having ≥10cm diameter at breast height (D.B.H) were identified and measured in 33 plots (250m x 20m). Species composition, structure, and conservation status of trees were assessed. Results of the study indicated that there were 129 tree species belonging to 100 genera and 33 families. The plo

Invasion by alien species (AS) is one of the most serious threats to ecosystems. In Europe, the Natura 2000 habitats network was established to protect habitats vital for the conservation of biodiversity and function of ecosystems. Therefore, the appearance of AS in Natura 2000 habitats is a warning signal that the most valuable European habitats may be endangered. However, quantitative studies encompassing a wide spectrum of habitats are lacking, and there is no insight into the differences in the level of invasion among habitats. Our survey is based on the State Monitoring of Natura 2000 dat

Cyatheaceae (tree ferns) appeared during the Jurassic period and some of the species still remain. Those species may have some morphological and/or physiological characteristics for survival. A tree fern was observed to suppress the growth of other ligneous plants in a tropical forest. It was assumed that the fern may release toxic substances into the forest floor, but those toxic substances have not yet been identified. Therefore, we investigated the phytotoxicity and phytotoxic substances of Cyathea lepifera (J. Sm. ex Hook.) Copel. An aqueous methanol extract of C. lepifera fronds inhibited

Populus italica (Du Roi) Moench, growing in different ecological conditions, acted as an indicator species. Sampling of poplar bark was carried out at 21 points, including the background one. The laboratory determined the following biogeochemical parameters: acidity, ash content, content of chemical elements. During the summer period 2022– 2023 samples were taken and analyzed. According to the data obtained, the pH of the aqueous extract of the samples varied from 5.
