How to escape from insect egg parasitoids: A review of potential factors explaining parasitoid absence across the Insecta: Escape from insect egg par…
2020
The egg is the first life stage directly exposed to the environment in oviparous animals, including many vertebrates and most arthropods. Eggs are vulnerable and prone to mortality risks. In arthropods, one of the most common egg mortality factors is attack from parasitoids. Yet, parasitoids that attack the egg stage are absent in more than half of all insect (sub)orders. In this review, we explore possible causes explaining why eggs of some insect taxa are not parasitized. Many insect (sub)orders that are not attacked by egg parasitoids lack herbivorous species, with some notable exceptions. Factors we consider to have led to escape from egg parasitism are parental egg care, rapid egg deve…
General framework for assessing the risks for in-soil organisms exposed to Plant Protection Products (PPP)
2017
The Panel on Plant Protection Products and their Residues (PPR) has been tasked by EFSA to revise the SANCO guidance Document on Terrestrial Ecotoxicology which is currently used for conducting the risk assessment for terrestrial non-target organisms, except for birds and mammals and non-target arthropods. For each group of organisms, the PPR Panel first summarises the science behind the respective risk assessment in a scientific opinion and, in a second step, EFSA will develop practical guidance on how to perform the risk assessment. The main scope of the revision is to take into consideration: (i) the entry into force of the Regulation 1107/2009 replacing the Directive 91/414/EEC; (ii) th…
Rhagoletis cerasi (L.) in Western Sicily: presence, damages and control in cherry orchards.
2012
The research was carried out from 2006 to 2010 in 12 cherry orchards in Western Sicily, were Rhagoletis cerasi (L.), the cherry fly, represents a problem for medium late ripening cultivars. Presence and infestation of the dipteran were monitored on local cultivars and effectiveness of some products allowed in organic farming was tested compared with net bags. The presence of the cherry fly was recorded in all cherry orchards except in two recently planted and isolated. The infestation on fruits was not very high until the end of May. Pyrethrum and spinosad did not lower the infestation, on the contrary nets reduced it.
Control of powdery mildew in cut roses using natural products in the greenhouse.
2009
Roses grown under greenhouse cultivation are commonly affected by diseases and regular fungicide applications are commonly used. The aim of this research was to identify natural products that can substitute and reduce the health and environmental impacts of typical chemical treatments in the control of powdery mildew [(Podosphaera pannosa (Wallr. Fr.) de Bary] and grey mould (Botrytis cinerea Pers.). Treatments were applied in the greenhouse on the cut rose cultivars Sunluck (Gold Strike®) and Nirpbredy (New Fashion®) growing in a soilless system. Oregano and clove essential oil at 0.5 ml/l (an emulsifier was added) and sodium bicarbonate (NaHCO3) at 4 g/l were sprayed on rose plants to run…
Studies on the genus Capparis L. (Capparaceae) in Lao PDR. IV: A new species from the Khammouan Province
2020
A new species of Capparis, C. florida, is described and illustrated from the Hin Nam No National Protected Area, Khammouan Province in central Lao PDR. The new species, collected in forest habitats of the Khammouan karst, belongs to sect. Monostichocalyx. It is an erect shrub characterized by the widely ovate or elliptical leaf-blade, by the flowers serial in supra-axillary rows, and by the slender ovary with evident style. Its affinities with related taxa, such as the widespread C. micracantha, are discussed and its conservation status assessed.
ARE MARINE PROTECTED AREAS (MPAs) EFFECTIVE IN PROTECTING FROM INVASIVE SPECIES? THE CASE STUDY OF CAULERPA CYLINDRACEA SONDER (CAULERPALES, CHLOROPH…
2019
The main purpose of Marine Protected Areas (MPAs) is biodiversity conservation. The effects that invasive species have on MPAs, and vice versa, are still not completely known, even though their assessment is crucial for MPA management and conservation purposes. In this respect, monitoring plans are essential and the involvement of citizen scientists may be fundamental. Our experience of Caulerpa cylindracea Sonder 1845 monitoring within the Egadi Islands MPA highlighted that the alga is widespread within the MPA, mainly at Favignana Island, also threatening valuable habitats such as vermetid reef and coralligenous formations. Moreover, Favignana is the island of the Aegadian archipelago mos…
Citizen science: a successful tool for monitoring biodiversity in Marine Protected Areas
2018
In the last few decades, anthopogenic activities, introduction of Non-Indigenous Species (NIS, i.e. organisms introduced outside of their natural range), and climate changes, have significantly affected Mediterranean marine biodiversity and ecosystem functioning (Coll et al., 2010). All that is also true for Marine Protected Areas (MPAs), whose major aim is biodiversity conservation. Therefore, monitoring and surveillance plans are strongly needed, and the creation of public awareness campaigns might be effective tool to plan effective management and conservation strategies in MPAs. Since intensive monitoring programs could be very expensive, citizen science, the involvement of citizens in …
Forest ecosystems in the Monti Sicani Park (Sicily)
2022
The authors analysed the forest ecosystems in the Monti Sicani Park (Sicily). In particular, the state of the natural and non-native forests in the Site of Community Interest (SCI ITA040005) - Monte Cammarata, Contrada Salaci, was evaluated in terms of distribution, evolution of forest dynamics and, silvicultural activities. The evolution of vegetation within two different forest plots are analysed and management strategies are proposed. The finding on Mount Cammarata of seedlings of Fagus sylvatica in the undergrowth of a conifer afforestation is noteworthy.
Five key attributes can increase marine protected areas performance for small-scale fisheries management
2016
AbstractMarine protected areas (MPAs) have largely proven to be effective tools for conserving marine ecosystem, while socio-economic benefits generated by MPAs to fisheries are still under debate. Many MPAs embed a no-take zone, aiming to preserve natural populations and ecosystems, within a buffer zone where potentially sustainable activities are allowed. Small-scale fisheries (SSF) within buffer zones can be highly beneficial by promoting local socio-economies. However, guidelines to successfully manage SSFs within MPAs, ensuring both conservation and fisheries goals, and reaching a win-win scenario, are largely unavailable. From the peer-reviewed literature, grey-literature and intervie…
Bright spots as climate‐smart marine spatial planning tools for conservation and blue growth
2021
Marine spatial planning that addresses ocean climate-driven change (‘climate-smart MSP’) is a global aspiration to support economic growth, food security and ecosystem sustainability. Ocean climate change (‘CC’) modelling may become a key decision-support tool for MSP, but traditional modelling analysis and communication challenges prevent their broad uptake. We employed MSP-specific ocean climate modelling analyses to inform a real-life MSP process; addressing how nature conservation and fisheries could be adapted to CC. We found that the currently planned distribution of these activities may become unsustainable during the policy's implementation due to CC, leading to a shortfall in its s…
