Floristic Quality Assessment of Wisconsin Lake Plant Communities with Example Applications [PDF]

open access: yesLake and Reservoir Management, 1999
ABSTRACT Floristic quality is a rapid assessment metric designed to evaluate the closeness of the flora of an area to undisturbed conditions. To be useful for a variety of monitoring applications it has to be calibrated for local conditions. Based on data from 554 lakes, this paper develops a floristic quality metric for Wisconsin lake plant ...

Potential Hazard of Open Space Fire in Black Pine Stands (Pinus nigra J.F. Arnold) in Regard to Fire Severity

open access: yesSouth-East European Forestry, 2020
Black pine (Pinus nigra J.F. Arnold) is one of the most important reforestation species for dry and rocky terrain in the sub-Mediterranean zone. Fire is an important factor in black pine stands that largely defines the distribution range of black pine ...

Gradient-Based Assessment of Habitat Quality for Spectral Ecosystem Monitoring

open access: yesRemote Sensing, 2015
The monitoring of ecosystems alterations has become a crucial task in order to develop valuable habitats for rare and threatened species. The information extracted from hyperspectral remote sensing data enables the generation of highly spatially resolved

Floristic Quality Index and Forested Floristic Quality Index: Assessment Tools for Restoration Projects and Monitoring Sites in Coastal Louisiana

open access: yes, 2018
In 2003, the Coastwide Reference Monitoring System (CRMS) program was established in coastal Louisiana marshes and swamps to assess the effectiveness of individual coastal restoration projects and the cumulative effects of multiple projects at regional and coastwide scales (Steyer et al., 2003). In order to make these assessments, analytical teams were

Floristic quality assessment signals human disturbance over natural variability in a wetland system

open access: yesEcological Indicators, 2013
a b s t r a c t A common concern regarding the popular Floristic Quality Assessment (FQA) method is whether the site floristic quality scores change with natural temporal and site-specific variability. The more ignored question is whether this background variability will confound the index of human disturbance.

Phylogenomics and Biogeography of the Eastern Asian–Eastern North American Disjunct Genus Hylodesmum (Fabaceae)

open access: yesBiological Diversity, EarlyView.
Integrating data from plastid genomes, nrDNA, and 353 low‐copy nuclear genes, this study establishes a robust phylogenetic framework for Hylodesmum. This framework supports a taxonomic revision recognizing 18 species and reveals a complex pattern of bidirectional EA–ENA dispersal, with mammals as a plausible dispersal agent. ABSTRACT Phylogenomics with
