Proper management of woods infested by bark beetle – clearing infested trees to prevent spread of bark beetle, or leaving them to preserve biodiversity – is a hotly debated topic. Differences in temperature regime between differentially managed areas are often-used arguments in these discussions. Results from the field measurements are confusing. Therefore, here we review previous studies and report our results of using thermal sensors in the field to determine the factors that might affect the differences in temperature reported in previous papers. Our results indicate that the variability recorded in one particular habitat, dry forest, is associated with the specific characteristics of the locality of each microsite/sensor. We conclude that it is important to consider not only the temperatures recorded but also describe microsites in detail in terms of vegetation structure, sunshine or numbers of trees per unit area.

We review the foraging behaviour of predaceous ladybirds in the light of current knowledge. Ladybirds should forage optimally to maximise their resources; however, they are limited – among other things – by their poor visual acuity. Ladybird foraging behaviour includes location of the habitat of its prey, location of prey and prey-selection. Chemical cues are important in locating the habitats of their prey. This is further driven by volatiles or semiochemicals emitted by injured plants, particularly in response to attack by herbivores. Various chemicals induce positive electroantennographic responses in ladybirds that guide them to prey sites. Honeydew secreted by aphids along with alarm pheromones or kairomones act as secondary chemical cues that narrow the search from extensive to intensive and help in prey location. Visual cues further aid prey-location and enable foraging adults to locate areas with patchy or abundant prey. Thereafter, ladybirds select their prey, which starts with random attacks that result in prey selection in terms of size and palatability. Prey selection seems to be host plant driven, i.e. aphids sequester host plant chemicals, which are imbibed by ladybirds. This is evident from the fact that nutritious prey cultured on toxic host plants are usually less preferred or rejected. Foraging ladybirds, especially larvae, can perceive ladybird footprints or odours that deter them from foraging. The above information could be useful in biocontrol programmes in which foraging ladybirds are manipulated by using chemicals as attractants or rearing aphids on nutritious host plants.

Prey-predator interactions have been modelled by numerous workers. Ecologists have continuously modified Lotka–Volterra equations in order to provide more realistic descriptions of the complexity of these interactions. The response of predator(s) to increasing prey density can be best described in terms of a functional response, which is an important criterion determining the success or failure of predator(s) to control fluctuating prey populations. The functional response of a predator is further differentiated into Holling’s Type I, II, III, IV and V. We discuss one-prey and one-predator interactions, in which the models are modified by the inclusion of steady-state satiation and growth factors. We review situations where two prey and one predator interact, and vice versa. We also discuss Holling’s Type IV model relevant to competition and food chains. There is a need to examine functional responses as these models were mostly developed by pure mathematicians and their relevance to field conditions remains largely untested. Prey-predator interactions can be affected even by small factors and ecologists should include these models in their experimental design when attempting to predict realistic interactions.

The IPCC IS92a scenario predicts climate changes including within-year fluctuations in precipitation and a temperature increase of 1.7 °C by the year 2050 and a further 2.7 °C by the year 2100. We attempted to detect these changes in the Sumava Mts. and compare them with climate changes in the surrounding foothills. We used meteorological data records for the years 1961-2017, provided by the Czech Hydrometeorological Institute (CHMI). We recorded a decrease in precipitation, including snow cover, in the mountains and in the foothills during the last 15-20 years. Air temperature has also increased significantly in spring and summer over the last two decades. We assume that the increase in spring temperature negatively affects snow cover and causes it to melt earlier. We found that all these changes affect both the Sumava National Park and the surrounding foothills at the same rate; as a result, natural disturbances such as windstorm and bark beetle infestations occur more often and are more severe in both areas. Thus, changes in temperature and precipitation must be also considered in future management planning.

Green Infrastructure (G.I.) is a sine qua non in contemporary planning. Green spaces can play a vital role in serving as grounds for developing G.I. and promoting environmental, social and economic benefits. In Athens and Thessaloniki (the only metropolitan areas in Greece) there has been no Green Infrastructure planning. However, existing and prospective green spaces can play a catalyzing role in the development of a Green Infrastructure. In fact, even though inadequate and insufficiently dispersed, urban green spaces present great potentials for embedding the features of “green”, “connectivity”, “multifunctionality” and “accessibility”, which are key to G.I. planning. The concept of Green Infrastructure has long been embedded in policy documents, such as the Master Plans of both metropolitan areas. And even if the G.I. term is not clearly stated in either Master Plans, there is a clear goal for the designing and networking of green spaces, to provide leisure opportunities and other functions, as well as accessibility to all citizens.

The aim of this article is to propose a measurable definition of green jobs based on balanced, durable and sustainable development, which is an example of both the Green Economy and New Public Management (NPM) concepts. This approach is justified due to the nature of NPM, which uses the goals of management and measures of effectiveness. In this paper, the definition of green jobs is formulated as tool for measuring, based on the Polish Classification of Activities (PKD), which has roots in the classifications proposed by UN the ISIC and Eurostat NACE. Then the ease with which this tool can be used is tested by determining the efficiency of labour market institutions. Therefore, the green jobs concept can be much wider than just a qualitative description of an organisation’s strategy. In this paper it is proposed that green job characteristics based on section E of PKD is more specific and because of its quantitative approach it is a suitable measurement not only in Polish conditions, but generally.

Extension of spatial planning from land to the marine space has recently become a key procedure for tackling the growing environmental and blue growth related challenges. However, given the transboundary nature of the sea (facilitating the flow of all kinds of materials and calling for special considerations in terms of resource and ecosystem management) not all the philosophy, planning models and procedures can be “transplanted” from terrestrial to marine spatial planning. Governance issues are subject to the same limitation.This paper discusses key differences in the marine environment (compared to the land), which affect marine spatial planning and governance and is structured around the following key issues: (i) the public status of the sea, which involves a wide spectrum of stakeholders (amongthem the maritime regimes), (ii) the sovereign rights in the sea that are not separately defined by each state but by UNCLOS (especially beyond the territorial waters), (iii) the geopolitical constraints on proclaiming EEZs that reduce the area within which each coastal country can practice MSP, (iv) the usually non-defined administrative limits in the marine parts of a coastal country that impede decentralization of competencies and decision making, and (v) the lack of geospatial and socio-economic and cultural data, which creates uncertainty both for the planners and decision-makers.This article concludes by highlighting the need for adopting a tailor-made MSP research agenda and by stressing the need to enhance crossborder cooperation as well as to make transboundary considerations when planning in the sea.

The development of urban and rural landscapes has entered a pioneering era with novel combinations of energy production andconsumption and related changes in the urban and rural fabric including associated socioeconomic issues. Accompanying this change isa realization that newly developing energy initiatives are more viable for development and upscaling and are less vulnerable to failure andresistance from society if they are well integrated into their local and regional contexts. However, institutional questions remain regardingthe required mechanisms and levels of integration, while simultaneously sustainable energy planning requires that the stakeholders withdiverse and conflicting objectives come to some degree of consensus. Inspired by these findings, a methodological approach for holisticenergy planning on a regional/local level was developed within the framework of the INTENSSS-PA project that is funded by HORIZON2020. The approach provides a holistic energy plan, which goes beyond a blueprint for allocating renewable technologies and is basedon the involvement of the wider community. Hence, this approach includes aspects such as the development of spatial concepts, newco-creating strategies, business cases, societal alliances and institutional changes and formats. To implement this approach, the LivingLab (LL) concept is applied. The case of Karditsa, in Greece, will be presented as evidence of the effectiveness of the proposed planningapproach.

The majority of the tourism industry on mainland Palawan is located in the north of the province. El Nido and Puerto Princesa are the most visited tourist areas in Palawan. The municipalities between these areas are considered to be sub-regional growth areas (Roxas, Dumaran and Taytay) since they serve as transition areas from one tourist hot spot to another. This study explores the tourism potentials of the sub-regional groregionwth areas using a potential analysis. By exploring the cases of Roxas, Dumaran and Taytay, various potentials were identified that could contribute to the development of this region of the island. Characterization resulted in the identification of the competitive advantages of each municipality, which were used to develop this region in a way that assures a sustainable growth of this subregion that complements that occurring in the tourist hot spots.

Every day citizens and visitors in Greek cities often find themselves constantly struggling with impediments: obstacles to their movement, their vision, to breathing air, etc. One cannot walk without being cautious so as not to stumble over a poorly repaired sidewalk, although it would have been easy to repair. You may find yourself next to the sea, but blocks of flats may hide it from you, restricting you to an endless maze, even though studies highlight the benefits for human health when coexisting with the natural bodies of water. One almost seems to be always close to roads with many car lanes and high traffic volumes; again despite the fact that studies highlight the adverse effects of car emissions on health. Why is this happening? Why do we choose and create such conditions? This paper attempts to shed some light on these questions by examining selected historical references to the ‘promised lands’ and some of the causes of the contemporary urban environmental degradation. The discussion focuses on an effort to comprehend the gap between the existence of urban environmental proposals and their lack of implementation at a greater scale, by (a) examining theories and proposals of major scholars concerning the environmental upgrading of urban space and by (b) examining the causes of the existing environmental urban degradation that currently affect many cities.

The discussion focuses on an effort to comprehend the gap between the existence of urban environmental proposals and their lack of implementation at a greater scale, by (a) examining theories and proposals of major scholars concerning the environmental upgrading of urban space and by (b) examining the causes of the existing environmental urban degradation that currently affect many cities.","PeriodicalId":11931,"journal":{"name":"European journal of environmental sciences","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2018-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45830500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
