Comparative studies on plant species richness, endemism, floristic composition, and structure between protected and unprotected forests are few in the Eastern Arc Mountains, one of the most biodiverse ecosystems in Africa. This study from one mountain range, the East Usambaras, examines floristic and structural tree data from 41-0.5 ha plots in four types of Eastern Arc forest: active agrofores...

Using complementary metrics to evaluate phylogenetic diversity can facilitate the delimitation of floristic units and conservation priority areas. In this study, we describe the spatial patterns of phylogenetic alpha and beta diversity, phylogenetic endemism, and evolutionary distinctiveness of the hyperdiverse Ecuador Amazon forests and define priority areas for conservation. We established a ...

One of the main steps in road and railway embankment restoration is the spreading of previously removed topsoil, which provides an input of seeds, organic matter and microorganisms and encourages the establishment of a vegetation cover, essential to stabilise the embankment and blend it with the landscape. However, topsoil is a scarce resource, prompting the search for economic alternatives wit...

Caragana, with distinctive variation in leaf and rachis characters, exhibits three centers of geographic distribution, i.e., Central Asia, the Qinghai-Tibetan Plateau (QTP), and East Asia, corresponding to distinct biomes. Because Caragana species are often ecologically dominant components of the vegetation in these regions, it is regarded as a key taxon for the study of floristic evolution in ...

The Atlantic forest is a terrestrial biome that extends along the Brazilian coast and has been subject of intense deforestation for decades. There are presently several efforts to try to preserve the flora and fauna of what remains from this region (e.g., Coco et al. 2014, Maciel-Silva et al. 2014, Missagia et al. 2014), but several questions on how the distinct floristic units of this biome ar...

A floristic exploration was carried out of the epiphyllous bryophytes in Mount Tebu Forest Reserve, state Terengganu, Peninsular Malaysia. Epiphyllous liverworts are reported for first time from Terengganu. total 54 species 18 genera and seven families were discovered, these, 43 newly The largest family is represented by Lejeuneaceae, with 44 (81%) 12 genera, genus Cololejeunea , 15 (28%). Most...

Long-term effects of Lupinus lepidus on vegetation dynamics at Mount St. Helens by Roger del Moral & Lara Rozzell Abstract: The nitrogen-fixing legume Lupinus lepidus is the most abundant herb on recently formed volcanic surfaces at Mount St. Helen. We compared vegetation structure in 30 Lupinus colonies in three age classes (old, mature, or young based on known years of their establishment) to...

a r t i c l e i n f o Spatial observations of plant occurrences contain a wealth of information on relations among species and on the relation between species and environmental conditions. Typically, inventory data of this kind are large co-occurrence matrices, and hence, direct ecological interpretations based on expert knowledge are often very difficult. Hitherto, ordination approaches have b...

Flora of Jahanbin mountain area in Chaharmahal and Bakhtiari province, located between Shahrekord and Hafshejan cities, with 12’187 hectares and 2’150 to 3’300 m elevation above sea level, is investigated. Vegetation of this area comprises of 273 species, 189 genera and 42 families. Asteraceae (37 species, 13.5%), Poaceae (31 species, 11.3%) and Fabaceae (25 species, 9.1%) were the most importa...
