This analysis is about the period from 1980 to 2004 and the economy activities selected are compose the structure of the Mossoro' s life, fixing shapes, functions and contents of the city territory, especially in its urban space to understand the present process of urban expansion and its relations with the dynamic of the city we recall history of this territory, wich as a urban word, connect the changes with the primary economy actives - commerce and sea salt extraction. ln this relation between the present process of urban expansion and the dynamic of the city economy, the economy activities studies where the sea salt extraction, and irrigated fruit crops organizes the space so they can be viable in all stages - production, trade and circulation - to be viable they change, amplify and build a urban space together with public policy, that also increases with the arrival of new inhabitant, service structure, mount by the public administration as well as by private resources. This work point out the needs of a development a new main plan for Mossoro, that will reorganize it's territory, but also grant the needs of its society, wich desires a more given city, where citizenship will be exercise with dignity / Este Trabalho tem por objetivo identificar os processos de expans?o urbana da cidade de Mossor?, relacionando-os com as Economias que dinamizam esta Sociedade. Esta an?lise corresponde ao per?odo de 1980 a 2004 e as atividades econ?micas selecionadas s?o aquelas que exercem um papel estruturante na vida da Cidade, por determinarem formas, fun??es e conte?dos no territ?rio do Munic?pio, e, principalmente em seu espa?o urbano. Para que se possam entender os processos da expans?o urbana atual e suas rela??es com a din?mica da Cidade, recorremos ? hist?ria desse territ?rio, que, ao definir-se como mundo urbano, sintonizam essas transforma??es com as atividades econ?micas fundadoras - o Emp?rio Comercial e a Extra??o de sal marinho. Nesta rela??o entre a expans?o urbana atual e a din?mica econ?mica da Cidade, as atividades econ?micas trabalhadas foram a Economia Salineira, a Extra??o de Petr?leo e G?s, e a Fruticultura Irrigada. Essas Economias (re)organizam um espa?o para viabilizar-se nas suas mais diversas etapas - produ??o, comercializa??o e circula??o - e, para tanto, modificam, ampliam e criam juntamente com as Pol?ticas P?blicas um espa?o urbano, que se expande tamb?m pela chegada de migrantes, pela estrutura de servi?os, montada pelo Poder P?blico, bem como pelo Capital Privado. O Trabalho aponta para necessidade de elabora??o um novo Plano Diretor para a Cidade, que reorganize esse territ?rio, n?o apenas na perspectiva do Capital e dos seus interesses, mas que tamb?m incorpore as aspira??es da sua Sociedade, que deseja uma Cidade mais generosa, onde a cidadania possa ser exercida com dignidade

Abstract Broadleaved forests are highly valuable biotopes with important recreational value and contain rich occurrences of species of conservation concern. To monitor the development of nature values in a forest ecosystem during an interval of approximately ten years, follow-up inventories were carried out, following the first inventories which took place ten years ago in two nature reserves (Karlsvik and Bohult) dominated by broadleaved trees in the county of Halland, Sweden. Indicator species of lichen and moss were searched for and compared to the first inventories. The results show that both reserves contain more indicator species today than approximately ten years ago, though a change in the species composition was observed. In Bohult fewer indicator lichens were observed, although more observations were made of indicator mosses - making the total number of indicator species higher than in the previous inventory. Potential explanations to the differing results of the two reserves were discussed and assessed to be for varied reasons. The observed increased occurrences of indicator species may be due to increased continuity leading to bigger and older trees which make way for more epiphytes. The observed decreased occurrences of indicator species may be due to human activity such as newly carried out clearcutting in close proximity to the reserve (which could lead to edge effects or other environmental stresses), nitrogen deposition or exploitation. An observed threat for both reserves is the increasing growth of norway spruce (Picea abies) which may outcompete broadleaved species and the potential indicator species they may inhabit. / Sammanfattning Ädellövskogar är mycket värdefulla naturtyper med höga rekreationsvärden och med rika förekomster av naturvårdsarter. För att utvärdera förändringen av skogliga naturvärden inom en tidsperiod av ca tio år utfördes uppföljningsinventeringar av två tidigare inventerade naturreservat som domineras av ädellövskog i Hallands län i Sverige. Signalarter av lavar och mossor eftersöktes och jämfördes med tidigare funna signalarter. Båda reservatens ursprungliga inventeringar utfördes för ca tio år sedan och resultaten visar att de båda reservaten nu har fler signalarter än tidigare, samtidigt som en förändring observerades i artsammansättningen då samtliga signalarter ej återfanns. I Bohult observerades färre signalartslavar, men fler signalartsmossor - vilket resulterade i ett större antal signalarter totalt för området. Potentiella förklaringar till de skilda förändringarna diskuterades och bedömdes bero på varierande orsaker. Det större antalet observerade signalarter skulle kunna förklaras av ökad tid för kontinuitet med fler grova och äldre träd som utgör lämpliga substrat för kolonisering av de eftersökta signalarterna. Det färre antalet observerade signalartslavar i Bohult skulle kunna bero på mänsklig påverkan i form av nyligen utförda kalavverkningar i angränsning till reservatet, vilket kan bidra till kanteffekter eller andra påfrestningar på miljön. Kvävenedfall, dikning av vattendrag eller annan exploatering föreslås också som möjlig orsak. Ett observerat hot för båda reservaten var igenväxningen av gran, vilken skulle kunna konkurrera med ädellövträden och de signalarter de kan husera.
