False broomweed is a troublesome weed on south Texas rangelands. The plant suppresses the growth of desirable herbaceous plant species and is unpalatable to livestock and wildlife. The objectives of this study were to evaluate multispectral satellite data for automated detection, classification, and mapping of false broomweed infestations. Determining the optimum phenological conditions for false broomweed detection was a major goal. Results indicate that satellite data can be used to detect major stands of this shrub and map the relative extent of infested areas. The best classification was obtained when the foliage of the shrub was fully developed and during periods of low herbaceous biomass production. Limited ground or aerial surveying will be needed to produce more exact estimates of the extent of false broomweed stands; however, these efforts can be focused on areas identified by satellite classification.

The objective of this study was to evaluate the ability of savanna thinning and enrichment with grasses to maintain local biodiversity and intensify biomass production in an area of Caatinga. The study was carried out in a Caatinga area thinned into savanna and an unmanipulated area during the rainy and rainy-dry transition seasons of 2016. The herbaceous biomass production, diversity, and equability of the thinned and unmanipulated areas were evaluated by calculating values of the Shannon-Weaver (H?) and Pielou (J?) indices. The establishment of massai and buffel grasses in the savanna-thinned area was also evaluated. The area thinned into savanna produced more native herbaceous forage biomass in both the rainy (1,940.55 kg ha-1) and rainy-dry transition seasons (1,918.55 kg ha-1) than that in the unmanipulated area in the same periods (78.42 and 37.40 kg ha-1, respectively), without compromising biodiversity, as the Shannon-Weaver and Pielou indices for the savanna-thinned area (H? = 1.48 and J? = 0.62, respectively) and for the unmanipulated area (H? = 1.29 and J? = 0.72) were comparable. The frequency of species with a known forage value in the area thinned into savanna was still able to increase by 141% in the rainy season and 1,700% in the rainy-dry transition season. Massai grass became better-established in the savanna-thinned area that buffel grass, where it produced up to 3 t of dry matter ha-1. The thinning and enrichment treatments promoted an increase in the biodiversity of the area, and moreover contributed to increases in forage biomass in the Caatinga.

Abstract. Background: Perioperative evaluation in peripheral artery disease (PAD) by common vascular diagnostic tools is limited by open wounds, medial calcinosis or an altered collateral supply of the foot. Indocyanine green fluorescent imaging (ICG-FI) has recently been introduced as an alternative tool, but so far a standardized quantitative assessment of tissue perfusion in vascular surgery has not been performed for this purpose. The aim of this feasibility study was to investigate a new software for quantitative assessment of tissue perfusion in patients with PAD using indocyanine green fluorescent imaging (ICG-FI) before and after peripheral bypass grafting. Patients and methods: Indocyanine green fluorescent imaging was performed in seven patients using the SPY Elite system before and after peripheral bypass grafting for PAD (Rutherford III-VI). Visual and quantitative evaluation of tissue perfusion was assessed in an area of low perfusion (ALP) and high perfusion (AHP), each by three independent investigators. Data assessment was performed offline using a specially customized software package (Institute for Laser Technology, University Ulm, GmbH). Slope of fluorescent intensity (SFI) was measured as time-intensity curves. Values were compared to ankle-brachial index (ABI), slope of oscillation (SOO), and time to peak (TTP) obtained from photoplethysmography (PPG). Results: All measurements before and after surgery were successfully performed, showing that ABI, TTP, and SOO increased significantly compared to preoperative values, all being statistically significant (P < 0.05), except for TTP (p = 0.061). Further, SFI increased significantly in both ALP and AHP (P < 0.05) and correlated considerably with ABI, TTP, and SOO (P < 0.05). Conclusions: In addition to ABI and slope of oscillation (SOO), the ICG-FI technique allows visual assessment in combination with quantitative assessment of tissue perfusion in patients with PAD. Ratios related to different perfusion patterns and SFI seem to be useful tools to reduce factors disturbing ICG-FI measurements.
