Precision, Applicability, and Economic Implications: A Comparison of Alternative Biodiversity Offset Indexes
2021
AbstractThe rates of ecosystem degradation and biodiversity loss are alarming and current conservation efforts are not sufficient to stop them. The need for new tools is urgent. One approach is biodiversity offsetting: a developer causing habitat degradation provides an improvement in biodiversity so that the lost ecological value is compensated for. Accurate and ecologically meaningful measurement of losses and estimation of gains are essential in reaching the no net loss goal or any other desired outcome of biodiversity offsetting. The chosen calculation method strongly influences biodiversity outcomes. We compare a multiplicative method, which is based on a habitat condition index develo…
Performance of a membrane-coupled high-rate algal pond for urban wastewater treatment at demonstration scale
2020
[EN] The objective of this study was to evaluate the performance of an outdoor membrane-coupled high-rate algal pond equipped with industrial-scale membranes for treating urban wastewater. Decoupling biomass retention time (BRT) and hydraulic retention time (HRT) by membrane filtration resulted in improved process efficiencies, with higher biomass productivities and nutrient removal rates when operating at low HRTs. At 6 days of BRT, biomass productivity increased from 30 to 66 and to 95 g.m(-3).d(-1) when operating at HRTs of 6, 4 and 2.5 days, respectively. The corresponding nitrogen removal rates were 4, 8 and 11 g N.m(-3).d(-1) and the phosphorous removal rates were 0.5, 1.3 and 1.6 g P…
A new species and a new synonymy of the plant bug genusiFulvius/ifrom Japan (Hemiptera: Heteroptera: Miridae: Cylapinae).
2017
Fulvius Stål (Cylapinae: Fulviini) is a large plant bug genus, with more than 80 described species distributed throughout the world (Schuh, 1995; 2002–2014). In Japan, five species listed below have been recorded mostly from the subtropical Ryukyu arc (Yasunaga, 2000, 2001; Yasunaga & Miyamoto, 2006; Yasunaga et al., 2012). Our recent closer examinations of these Japanese species suggest that (1) what was previously identified as Fulvius dimidiatus Poppius represents an undescribed species, and (2) F. nakatai Yasunaga & Miyamoto described from Okinawa Island is evidently conspecific with F. subnitens Poppius that was described from New Guinea but is now known from pantropical zones …
Taxonomic review of the bifenestratus species group of the genus Fulvius Stål with descriptions of two new species (Hemiptera, Heteroptera, Miridae, …
2018
Two new species of the genus Fulvius Stål are described from the Philippines and Papua New Guinea. A taxonomic review of representatives of the F.bifenestratus species group, illustrations of the male genitalia, a color habitus image of each species, and a key to species of the group are provided.
Do Grapholita funebrana Infestation Rely on Specific Plum Fruit Features?
2019
The effective control of the plum fruit moth, Grapholita funebrana (Lepidoptera: Tortricidae) still represents a difficult challenge for organic plum farming. Little information is available on the susceptibility of plum cultivars to this moth pest. We investigated the roles of several fruit parameters (i.e., shape, volume, hardness, fruit colour, and physiochemical properties) on the susceptibility of four different plum cultivars (Angeleno, Friar, President and Stanley) to G. funebrana attack. Field data demonstrated the importance of some fruit parameters (i.e., elongation index, sugar degree, titratable acidity, cover colour percentage) on susceptibility to G. funebrana infestation. Und…
Characterizing the effects of salt stress in Calendula officinalis L
2017
In this study the effects of salt stress on growth and several stress markers were investigated in the ornamental and medicinal plant Calendula officinalis. One month old plants were submitted to increasing concentrations of salt up to 150mM NaCl for a period of 30 days. Salinity affected growth in terms of stem length and fresh weight of the plants, but water content remained unchanged indicating a certain tolerance to low and mild concentrations of salt. Although Na+ and Cl− increased in parallel to applied salt treatments, the levels of K+ and Ca2+ showed no significant change, while Mg2+ levels recorded a two folds increase upon the application of the highest salt concentration. Other m…

A Cultivar-Sensitive Approach for the Continuous Monitoring of Olive (Olea europaea L.) Tree Water Status by Fruit and Leaf Sensing
2020
Sustainable irrigation is crucial to reduce water use and management costs in modern orchard systems. Continuous plant-based sensing is an innovative approach for the continuous monitoring of plant water status. Olive (Olea europaea L.) genotypes can respond to drought using different leaf and fruit physiological and morphological mechanisms. This study aimed to identify whether fruit and leaf water dynamics of two different olive cultivars were differently affected by water deficit and their response to changes of midday stem water potential (Ψstem), the most common indicator of plant water status. Plant water status indicators such as leaf stomatal conductance (gs) and Ψstem were measured…
Detecting Mild Water Stress in Olive with Multiple Plant-Based Continuous Sensors.
2021
A comprehensive characterization of water stress is needed for the development of automated irrigation protocols aiming to increase olive orchard environmental and economical sustainability. The main aim of this study is to determine whether a combination of continuous leaf turgor, fruit growth, and sap flow responses improves the detection of mild water stress in two olive cultivars characterized by different responses to water stress. The sensitivity of the tested indicators to mild stress depended on the main mechanisms that each cultivar uses to cope with water deficit. One cultivar showed pronounced day to day changes in leaf turgor and fruit relative growth rate in response to water w…
Nomenclatural synopsis of cirsium sect. Eriolepis (asteraceae) in Italy
2021
The names of the Italian taxa in Cirsium sect. Eriolepis are discussed. The accepted names are: Cirsium echinatum, C. eriophorum subsp. eriophorum, C. eriophorum subsp. spathulatum, C. ferox, C. italicum, C. lacaitae, C. lobelii, C. morisianum, C. scabrum, C. tenoreanum, C. vallis-demonii subsp. vallis-demonii, C. vallis-demonii subsp. calabrum comb. nov., and C. vulgare (= C. crinitum, C. sylvaticum). Four accepted names are typified by specimens preserved at FI (one lectotype), G (one lectotype and one neotype), P (one lectotype), and by illustrations (two lectotypes). Several other heterotypic synonyms of taxa described from Italy are discussed and six of them are typified. A new combina…
