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.","PeriodicalId":11931,"journal":{"name":"European journal of environmental sciences","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2018-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42397580","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}

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.","PeriodicalId":11931,"journal":{"name":"European journal of environmental sciences","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2018-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45708015","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}

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.","PeriodicalId":11931,"journal":{"name":"European journal of environmental sciences","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2018-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48791714","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}

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.","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":"42611143","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}

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.","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":"48026563","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}

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.","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}
