Abstract The present work aims to provide a discussed floristic treatment for Cuphea (Lythraceae) from the Rio Grande do Sul state, Brazil. Morphological, ecological and geographic distribution data were obtained through revision of several herbaria collection expeditions. A morphological analysis seeds under scanning electron microscopy preliminary assessment conservation status species includ...

BACKGROUND Potentially Inappropriate Prescriptions (PIPs) are a common cause of morbidity, particularly in the elderly. OBJECTIVE We sought to understand how the Screening Tool of Older People's Prescriptions (STOPP) prescribing criteria, implemented in a routinely used primary care Electronic Medical Record (EMR), could impact PIP rates in community (non-academic) primary care practices. M...

Assessing and mapping patterns of (semi-)natural vegetation types at a large spatial scale is a difficult task. The challenge increases if the floristic variation within vegetation types (i.e., subtype variation of species composition) is the target. A desirable way to deal with this task may be to address such vegetation patterns with remote-sensing approaches. In particular data from multispe...

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 ...

Myanmar (Burma) constitutes a significant component of the Indo-Myanmar biodiversity hotspot, with elements of the Indian, the Indochina, and the Sino-Japanese floristic regions, yet thus far only a few reliable sources of the country's flora have been available. As a part of a contribution for the floristic inventory of Myanmar, since it is important in a floristic survey to obtain as much inf...

The paper is aimed to assess the effect of anthropogenic fragmentation on biodiversity plants in northern meadow steppes located southeast Nizhny Novgorod region. were chosen as a model group. A quantitative analysis dependence number species area habitats was carried out according data collected at 158 sites and steppe meadows with total 10752 ha. For each surveyed, area, proportion, covered c...

Varied floristic works relevant to Kashmir Himalaya were thoroughly examined compile taxonomic contributions of various taxonomists viz. a diversity in gymnosperms this region. Extensive field surveys and standard methods used locate, collect, identify prepare an updated list the target group. A total 25 species belonging 13 genera 6 families 4 orders have been documented from Himalaya. Wild ar...

Canonical correlations analysis uses a secondary set of multivariate observations to correlate with, and thereby help to explain, differences among a primary set of multivariate observations. In ecology, the variables of the primary data set may be of the “presence/absence” type, or they may be the abundances of individual species in a species list, whereas the secondary set often involves envi...

floristic studies are fundamental for the applied sciences such as rangelandmanagement and conservation. unique ecological and climatic conditions in the northernkhorasan province (nkp) make it a remarkable habitat for the floristic studies. plant specieswere collected from 50 field sites, representing major habitats of winter and rural rangelands.surveys were conducted during active growth per...
