Повний текст джерелаFor the majority of large ungulates living in temperate regions winter is the limiting season, because of the combined effects of lack of resource availability and severity of climatic conditions. Those species that did not develop any particular morphological and physiological adaptation to cope with winter severity may adopt movement and space use tactics instead (like e.g. migration). Specifically, these space use patterns may emerge at different spatiotemporal scales to allow individuals to accede the resources they need and escape unfavourable conditions, thus determining both individual fate and population dynamics. A detailed understanding of the relationship between limiting factors in wintertime, and individual movement response, is remarkable to preserve and manage wildlife successfully, especially in the context of fast-occurring climate change that induces important alterations in landscape and resource distribution (e.g. changes of snow cover patterns). The comparison of movement tactics under different environmental scenarios, e.g. by means of large –scale analysis at the species distribution range, represents a valuable approach to work in that direction and to assess the effects of landscape alteration on individual movement. Roe deer (Capreolus capreolus) is an excellent model species to investigate these issues, because its distribution range covers most of Europe, thanks to its high ecological plasticity. For those populations that live in northern and mountain environments, winter is the limiting season because roe deer lack any morphological and physiological adaptations to cope with winter severity. In spite of the adoption of specific movement tactics such as partial migration from summer to winter ranges, roe deer may still face limiting conditions in some areas of the distribution range exposed to winter severity

The need for new tools to detect pollutants and of importance in the subject, electrochemical sensors are shown as a great alternative, considering its low cost, good limits of detection, and speed of analysis. An electro-spinning technique is a small fiber production technique where many possibilities for a sensor construction are offered, mainly using biodegradable polymers. This work has the objective of incorporating polymeric fibers with graphite optimized by an electrochemical technique, as well as an electrochemical sensor capable of obtaining a detection limit for the 2,4,6-trichlorophenol compound. A total of 35 experiments were carried out, using five different electrophilic techniques (needle distance to the collector, flow, tension, % of polymers, and % of graphite), as fibers as morphologically characterized using optical microscopy, SEM and a test of Wettability. For physical e structural analyzes, DSC, TGA and FTIR analyzes were performed, where it was sought to know if the incorporation of graphite into the polymer is capable of altering its structure. Then, for a sensor construction, a membrane obtained by electrospinning was then subjected to a heat treatment of 500°C for 3 hours, the powder obtained was mixed with the Nujol® wetting agent, thereby forming a uniform paste which was inserted into the End of a hypodermic plastic syringe with a silver wire for electrical contact, being manually pressed. The electrode was subjected to a characterization and an evaluation where a limit of detection was established for compound 2,4,6-TCP, in addition to a test with real samples collected in water treatment station supply. The minimum diameter obtained in the fibers was 1.49μm, using where the stress and voltage flows interacted, showing the effect of the second most significant order among all. As it analyzes morphologically revealed that a graphite incorporation has given the polymer membrane new characteristics to the surface, while as thermal analyzes show what is graphite changing a structure of the fibers when incorporated as its own. The only oxidation pic viewed with the Cyclic Voltammetry analysis characterizated the sensor containing a irreversible behavior face to 2,4,6-TCP. Based on the Square Wave Voltammetry analyzes, was obtained a detection limit for the 2,4,6-TCP of 1x10-7 mol.L-1 and showed a detection of the concentration test of 6x10-7 mol.L-1, with recovery rates of water samples between 80 and 93%, both in accordance with current Brazilian legislation.
A necessidade de novas ferramentas para detecção de poluentes é de suma importância atualmente, neste quesito, sensores eletroquímicos se mostram como uma ótima alternativa, tendo em vista seu baixo custo, bons limites de detecção, e rapidez na análise. A eletrofiação é uma técnica de produção de fibras em pequenas escalas onde muitas possiblidades para a construção de sensores são ofertadas, principalmente utilizando polímeros biodegradáveis. Este trabalho tem por objetivo obter fibras poliméricas incorporadas com grafite de forma otimizada pela técnica de eletrofiação, além de desenvolver um sensor eletroquímico capaz de obter um limite de detecção para o composto 2,4,6-Triclorofenol. Foram realizados 35 ensaios utilizando cinco diferentes parâmetros para eletrofiação (Distância da agulha ao coletor, fluxo, tensão, % de polímeros, e % de grafite), as fibras foram caracterizadas morfologicamente utilizando microscópio óptico, MEV, e um teste de molhabilidade. Para as análises físicas e estruturais, foram realizadas analises de DSC, TGA e FTIR, onde buscou-se saber se a incorporação de grafite ao polímero foi capaz de alterar sua estrutura. Depois, para a construção do sensor, a membrana obtida por eletrofiação foi então submetida a um tratamento térmico de 500°C por 3 horas, e o pó obtido foi misturado ao agente umectante Nujol®, formando assim uma pasta uniforme que foi inserida no interior da extremidade de uma seringa plástica hipodérmica com um fio de prata para o contato elétrico, sendo prensada manualmente. O eletrodo foi submetido a uma avaliação onde estabeleceu-se uma caracterização e um limite de detecção para o composto 2,4,6-TCP, além de um teste com amostras reais coletadas em estação de tratamento de águas de abastecimento. O Diâmetro mínimo obtido nas fibras foi de 1.49μm onde os parâmetros fluxo e tensão interagiram apresentando o efeito de segunda ordem mais significativo entre todos. As analises morfológicas revelaram que a incorporação de grafite concedeu a membrana polimérica novas características a superfície, enquanto que as análises térmicas mostraram que o grafite alterou a estrutura das fibras quando incorporado as mesmas. Ao obter apenas um pico de oxidação com a análise de voltametria cíclica o sensor apresentou um comportamento irreversível frente ao 2,4,6-TCP. Já com base nas análises de voltametria de onda quadrada obteve-se com o sensor um limite de detecção para 2,4,6-TCP de 1x10-7 mol.L-1 e o teste com águas de abastecimento detectou a concentração de 6x10-7 mol.L-1, com taxas de recuperação das amostras de água tratada entre 80 e 93%, ambas em concordância com a legislação brasileira vigente.

Повний текст джерелаAim: Product descriptions can communicate the beneficial properties that comes with a product, which can make the product stand out, among others. In recent decades, there has been an increased interest in both sensory and environmentally friendly product descriptions and for companies, it is becoming increasingly important to succeed in identifying the factors that affect consumers’ willingness to pay. The purpose of this study is therefore to investigate how sensory and environmentally friendly product descriptions affect consumers’ willingness to pay. Method: The method has a deductive approach, and our empirical data has been based on a quantitative method in the form of a survey. The population refers to individuals between the ages of 15 and 75 who either drink coffee regularly or have ever bought brewed coffee in a grocery store. The results have been processed in SPSS where they have been analyzed based on descriptive statistics, correlation analysis and regression analysis. Result & Conclusion: The results of the study show that sensory product descriptions of coffee have a positive effect on the consumer’s willingness to pay. Sensory taste attributes are the most important to communicate in a product description to appeal to the consumer. On the other hand, the results of the study show that product descriptions that are ecological and Fairtrade-labeled have a stronger impact on the consumer’s willingness to pay for coffee than with sensory product descriptions. Contribution of the thesis: Our contribution to the subject of business administration and marketing is that product descriptions for coffee should primarily communicate ecological and Fairtrade-labels if such exist, to influence the consumer’s willingness to pay. In the case of non-ecological or Fairtrade-labeled products, the sensory attributes should be communicated to have a positive impact on the consumer’s willingness to pay. Suggestions for future research: After this study, we can state that the willingness to pay differs depending on which product description is presented. It would therefore be of interest to also look at different brands for coffee when producing different types of product descriptions to see if the willingness to pay changes. For future research, it would also be of interest to see how sensory product descriptions in combination with environmentally friendly product description had affected the willingness to pay.

Obesity in adolescence is associated with a complex web of ecological, psychosocial, and physiological factors, and many of these factors relate to nutrition and physical activity behaviors. Before interventions are developed, researchers need to know what factors specifically influence an adolescent’s food choices and physical activity within the community context. Cultural norms, school environment, and neighborhood attributes are examples of factors that may vary across different communities, and accounting for this variation can be quite challenging, unless community perspectives are acknowledged. The use of qualitative data from focus groups has shown to be an effective way of gathering community perspectives about the diversity of their views and experiences. The current study used focus groups to reveal facilitators and barriers to healthy eating behavior and physical activity engagement in 6th to 8th grade youth in a low-income community in South-Western Kansas. This methodology enabled community members (adolescents, parents, and teachers) to discuss and articulate their perceptions in relation to 6th to 8th grade youth’s eating habits and physical activity, and assessed available resources, needs, and opportunities for developing effective and sustainable intervention approaches in the community. Using the socio-ecological model, individual influences (e.g., taste preferences), social influences (e.g., parent and peer influences), and larger contextual influences (e.g., school) on early adolescent health were assessed. This information will be used to develop interventions addressing factors at these different levels of influence that are needed to improve eating habits and physical activity of youth in the community.

Повний текст джерелаThe main goal of this dissertation is to calibrate the cerrado vegetation physiognomies (Brazilian savannas) with their seasonal spectral signatures to help the monitoring and the conservation of their remnants. The study area is the cerrado Pé-de- Gigante (belonging to State Park of Vassununga in Santa Rita do Passa Quatro -SP). Using NDVI images derived from TM-Landsat (red and near infrared), the physiognomic classes were identified spectral and seasonally. To validate the method, a map of areas of probable physiognomies occurrence were build using NDVI images from dry and wet season. After field checking, the NDVI values of 5 dates were extracted to establish the NDVI range of each physiognomy. Using the digital terrain model, slope and aspect maps were used to prepare another map with 5 zones (N, S, W, E and flat), looking for to test the topographic effect in NDVI. Added to this, the NDVI classes were compared with the literature, as well as the separate signature in red, near infrared and middle infrared. It was noticed a strong weather condition influence over the physiognomies along the seasons, corroborated by the NDVI variation classes obtained from satellite imagery.

(Jardim Sensorial da UFJF, um Espaço de Terapia e Conscientização). O Jardim Sensorial (JS) da Universidade Federal de Juiz de Fora (UFJF) é formado por três canteiros circulares. Apresenta a entrada no leste, referenciando o sol nascente (fogo), seu oposto oeste corresponde à terra do poente, ao sul o elemento água vem com as chuvas, e ao norte temos o ar de expansão. Este referencial é baseado no “Opy”, casa de reza Tupi-Guarani. Contém 30 plantas sensoriais distribuídas nestes quadrantes. O trabalho avaliou as sensações e percepções do JS por visitantes adultos (18 a 59 anos) a partir de questionários semiestruturados respondidos voluntariamente pelas pessoas que visitavam o JS necessariamente pela 1ª vez, a fim de comparar duas formas de visita, uma quando os visitantes necessariamente caminhavam calçados e sem venda, não tocando nem cheirando nenhuma planta, denominada forma controle (FC) e outra quando os visitantes necessariamente realizavam o percurso descalços e de olhos vendados, tateando e cheirando as plantas, denominada forma Jardim Sensorial (FJS). Foram respondidos 474 questionários pelos adultos, sendo para FJS, 239 questionários para o sexo feminino e 118 para o masculino, e para a FC, 64 questionários para o sexo feminino e 53 para o masculino. A média de idade dos visitantes foi de 25 anos e 98% experimentou este modelo sensorial pela primeira vez, confirmando o caráter inovador do JS. Os sentimentos gerados foram predominantemente positivos, destacando-se Tranquilidade, Bem-estar, Calma e Paz (para ambas as formas de visita) demonstrando que o JS alivia o stress cotidiano provocando relaxamento. A partir da análise estatística, a alteração nas formas de percepção geradas na FJS, aumento do tato, olfato, audição e energia, alteração da percepção do tempo e espaço, as lembranças provocadas pelo aroma de determinadas plantas, além dos sentimentos positivos despertados pela percepção da planta dos pés, demonstram que essa forma de visita retira o visitante do estado contemplativo cotidiano além de apresentar um caráter provocativo. A educação ambiental como destaque de transmissão de conhecimento, aponta o caráter conscientizador do JS. O JS promove o alívio do estresse, pois espontaneamente provoca sentimentos positivos, tornando o visitante mais relaxado e onde tato e olfato agradáveis promovem sinergia e consequente bem-estar.
(UFJF Sensory Garden, a Place of Theraphy and Awareness). The Sensory Garden (SG) of Federal University of Juiz de Fora (UFJF) is formed by three circular beds. Its entrance is directed to the east referring to the rising sun (fire), the west corresponds the land of the sunset, to the south the element water comes with the rains, and to the north, it has the air of expansion. This reference is based on "Opy", a Tupi-Guarani prayer house. The SG has 30 sensory plants distributed in these quadrants. The work evaluated the sensations and perceptions of SG through adult visitors (with age between 18 and 59 years) that answered voluntarily a semistructured questionary, in order to compare the two ways of visit: one when the visitors necessarily walked through the space with shoes and with no blindfold, without touching nor smelling any plant – it´s called Control Form (CF), and another one when visitors necessarily performed the course barefoot and blindfolded, groping and smelling the plants, - this way is called Sensory Garden Form (SGF). 474 questionnaires were answered by the adults, being 239 questionnaires for females and 118 for males in SGF, and for 64 surveys for women and 53 for men in CF. The average age of the visitors was 25 years, and 98% experienced this sensory model for the first time, confirming the innovative character of SG. The feelings generated were predominantly positive, standing out Tranquillity, Well-being, Calm and Peace (for both forms of visit) demonstrating that SG relieves daily stress causing relaxation. From the statistical analysis, the alteration in the forms of perception generated inside the SG increased tact, smell, hearing and energy. It also altered the perception of time and space, activated memories by the aroma of some plants, and awakened positive feelings by the judgment of the soles of the feet. All those sensations demonstrate that this form of visit removes the visitor from the daily contemplative state and besides that, present a provocative character. Environmental education as a highlight of knowledge transmission points out the awareness of SG. The SG promotes stress relief by spontaneously provoking positive feelings, making the visitor more relaxed and where pleasant tact and sense of smell promote synergy and consequent well-being.

O bioma Caatinga, ecossistema de clima semi?rido localizado no nordeste do Brasil, apresenta forte sazonalidade com baixo regime de precipita??o. Esta regi?o possui as proje??es de mudan?as clim?ticas mais alarmantes do pa?s, com o aumento temperatura do ar e a redu??o da pluviosidade com tend?ncias mais fortes que as previs?es m?dias globais. As mudan?as clim?ticas no bioma podem acarretar na diminui??o da cobertura vegetal e altera??o de sua distribui??o, bem como do funcionamento ecossist?mico. Desta forma, influencia fortemente na diversidade de esp?cies. Nesse contexto, a proposta desse estudo ? modelar a din?mica da vegeta??o em fun??o das condi??es ambientais (pluviosidade e temperatura), bem como predizer as consequ?ncias das mudan?as clim?ticas, baseadas nesses determinantes ambientais para o verdor da vegeta??o. O ?ndice de vegeta??o EVI (Enhanced Vegetation Index) foi usado para estimar o verdor da vegeta??o no bioma. A fim de considerar a forte autocorrrela??o temporal e espacial, bem como a heterogeneidade presente nos dados, v?rios modelos GLS (Generalized Least Squares) foram desenvolvidos e comparados para se obter o melhor modelo. Tal modelo refletiu a influ?ncias das condi??es ambientais na previs?o do verdor da vegeta??o no futuro. Diante da aplica??o dos novos cen?rios de mudan?as clim?ticas no modelo, a modifica??o dos determinantes ambientais, pluviosidade e temperatura, influenciou negativamente no verdor da vegeta??o no bioma Caatinga. Esse modelo foi usado para criar imagens de vegeta??o potencial nos per?odos presente e futuro do bioma Caatinga considerando que at? 2040 haver? uma diminui??o de 20% da precipita??o e um aumento de 1?C na temperatura; at? 2070 haver? uma diminui??o de 35% na precipita??o e um aumento de 2,5?C na temperatura; e at? o final do s?culo o percentual de diminui??o das chuvas alcan?ar? 50% e a temperatura ter? um aumento de at? 4,5?C. Os resultados desse estudo sugerem que o funcionamento do ecossistema ser? afetado com a diminui??o de 5,9% do verdor da vegeta??o at? 2040, 14,2% at? 2070 e 24,3 % at? o final do s?culo. A vegeta??o da Caatinga em ?reas de baixa altitude (maior parte do bioma) ser? mais afetada pelas mudan?as clim?ticas.
The Caatinga biome, a semi-arid climate ecosystem found in northeast Brazil, presents low rainfall regime and strong seasonality. It has the most alarming climate change projections within the country, with air temperature rising and rainfall reduction with stronger trends than the global average predictions. Climate change can present detrimental results in this biome, reducing vegetation cover and changing its distribution, as well as altering all ecosystem functioning and finally influencing species diversity. In this context, the purpose of this study is to model the environmental conditions (rainfall and temperature) that influence the Caatinga biome productivity and to predict the consequences of environmental conditions in the vegetation dynamics under future climate change scenarios. Enhanced Vegetation Index (EVI) was used to estimate vegetation greenness (presence and density) in the area. Considering the strong spatial and temporal autocorrelation as well as the heterogeneity of the data, various GLS models were developed and compared to obtain the best model that would reflect rainfall and temperature influence on vegetation greenness. Applying new climate change scenarios in the model, environmental determinants modification, rainfall and temperature, negatively influenced vegetation greenness in the Caatinga biome. This model was used to create potential vegetation maps for current and future of Caatinga cover considering 20% decrease in precipitation and 1 ?C increase in temperature until 2040, 35% decrease in precipitation and 2.5 ?C increase in temperature in the period 2041-2070 and 50% decrease in precipitation and 4.5 ?C increase in temperature in the period 2071-2100. The results suggest that the ecosystem functioning will be affected on the future scenario of climate change with a decrease of 5.9% of the vegetation greenness until 2040, 14.2% until 2070 and 24.3% by the end of the century. The Caatinga vegetation in lower altitude areas (most of the biome) will be more affected by climatic changes.

Повний текст джерелаO forrageio de abelhas geralmente depende de disponibilidade de flores, intensidade de luz e temperatura. Contudo, algumas abelhas desenvolveram hábitos noturnos e voam durante os crepúsculos e a noite. Não se sabe como essas abelhas lidam com os fatores ambientais, especialmente os reduzidos níveis de luminosidade. Dado que os olhos compostos de aposição de abelhas funcionam melhor em maiores luminosidades, espera-se uma maior dependência da luz para os grupos noturnos. Abelhas noturnas e crepusculares são visitantes frequentes do cambuci (Campomanesia phaea, Myrtaceae) no sudeste do Brasil. Nosso objetivo foi investigar como a intensidade de luz afeta a visitação floral do cambuci por abelhas noturnas e crepusculares, controlada também por outros fatores ambientais. Para isso, contamos as visitas a cada minuto ao longo de 30 noites/crepúsculos em 33 árvores de cambuci em um pomar comercial, medindo as seguintes variáveis ambientais: intensidade de luz, disponibilidade de flores, temperatura, umidade e velocidade do vento. A intensidade de luz foi a única variável que explicou a visitação floral de abelhas noturnas no cambuci, a qual tem um pico em níveis intermediários de luz que ocorrem ao redor de 30 minutos antes do nascer do sol. O limiar mínimo de intensidade de luz para as abelhas começarem a voar foi de 0.00024 cd/m2, o primeiro valor registrado para abelhas noturnas e crepusculares procurando por flores em um contexto agroflorestal. Nossos resultados destacam pela primeira vez como as abelhas noturnas dependem da luz para explorar recursos e mostram que essa dependência, para abelhas em geral, não é sempre linear, como postulado por modelos teóricos prévios. Este é o primeiro passo para entender como abelhas noturnas reagem a fatores ambientais. Nossos dados também trazem alertas para possíveis efeitos negativos da poluição luminosa à noite para a interação entre cambuci e abelhas noturnas

Повний текст джерелаThis thesis is an attempt to provide the philosophical foundations for an ecological conversion while revealing the ontological aspects of the ecological crisis. Following the path described in the Laudato Si’ encyclical letter, where Pope François launches a vibrant call for ecological conversion, the author seeks to adress the philosophical issues in relation to this notion. Refering to philosophers such as Heidegger and Hans Jonas, the first part of this research accounts for the necessity of a true ecological conversion to face the metaphysical « peril » represented by the technical way of mind which leads to an unauthentic « being-in-the-world ». As catastrophism rages, the author underlines the humanistic aspect of its founders’ thought (Gûnther Anders, Jacques Ellûl) while confronting their vision to Ernst Bloch’s « Principle of Hope ».The second chapter of the thesis aims at laying down the ethical and religious foundations of the concept of conversion. From Plato’s metanoia to stoïcian and epicurian soul therapies, the author explores the importance of the knowledge of nature (physis) in the process of epistrophè (return to one’s « Inner Self »). Can these therapies be considered as the roots of a true ecological conversion throughout which we could not only modify the way we look at nature but also be transformed by it? If the answer is yes, what would the terms be? From this perspective, what is the specificity of Christian metanoia compared to Plato’s? To what extent can the doctrine of the “spiritual senses” experienced by both the Franciscan mystic and the neptical Fathers’ « Prayer of the heart » - be considered a crucial step to a living experience of ecological conversion that appeals to our body and heart? To carry out this research, the author relies on the phenomenological methodology, evidencing the links between conversion and reduction.The last part, more specifically dedicated to modern ecology, relies on the definitions of ecological conversion outlined with greek and Christian authors to think through a deep change in our « affect for the world ». Refering to Merleau Ponty’s notions of « flesh of the word » and « wild being », the author endeavours to develop the concept of “universal empathy” as the corner stone of environmental ethics. Through a merleau-pontian interpretation of two major ecological schools of thought, wilderness and deep ecology, the thesis provides tools for elaborating a relational ontology based on two concepts. The first one, called deepening of the Self, refers to the wilderness. The author shows that what has to be preserved is not only territories such as natural reserves but the “wild being” in the innermost part of ourselves so as to enable us to be transformed by nature itself through this experience of wilderness described by famous authors such as Henri-David Thoreau in Walden life in the woods… The second one, called “enlargment of the Self” refers to the experience described by Arne Naess as identification to other living beings as a source of self-realization, echoing the merleau-pontian “flesh of the word”.Aware of the limits of western thought to reach this universal empathy based on non-duality, the author points out, in a conclusive paragraph, the influence of the buddhist way of mind on Arne Naess’s deep ecology, explores a spirituality of the resonance with the world through zen buddhism embodied by Master Dogen, and goes as far as thinking an “echology of Joy”

In Brazil, the production of organic vegetables has increased approximately 40% per year in the last decade. Considering the above, 108 samples of irradiated, minimally processed, organic watercress from producers in the region of Sao Roque, Sao Paulo, were collected through November 2005 to March 2007, to assess the microbial ecology and vitamin C content. Samples of organic watercress collected at the farm level and at the industry level showed populations higher than 3,0 UFC/g for aerobic mesophilic, psychrotrophic, Pseudomonas spp, fecal coliforms and E. coli. Salmonella, E. coli O157:H7 and L. monocytogenes were not detected along the production chain. Comparing the minimal process and the combination of minimal process and irradiation, the combination was more efficient since even the lower dose (1 kGy) was sufficient to reduce the population of the various groups of microorganisms. The ascorbic acid, dehidroascorbic acid and vitamin C content varied at all stages of minimal processing as well as with the exposed doses of irradiation (1, 2 and 3 kGy). The population of L. monocytogenes decreased approximately 4.5, 5.5, and 5.9 log cycles, depending on the exposed doses, throughout the shelf life of irradiated minimally processed organic watercress. Similar behavior was showed by the Salmonella population. Sensory evaluation results showed that previous knowledge or none by consumers does not interfere with the acceptance and intention of purchase of irradiated minimally processed organic watercress. Thus the process of irradiation to improve the microbiological quality of minimally processed organic watercress is feasible provided that Good Agricultural Practice, Good Practice Production and Good Irradiation Practice are followed.

In order to survive and reproduce, human spoil the ecological environment. We need to monitor and collect the change to inform and protect people. How to gather information from nature is the important issue. We study and solve this problem by the wireless sensor network. The wireless sensor network will self-organize [1]. We will make a real-time monitoring, observation data collection system environment. Implementing control on the use of Wang Yang company produced the board, the use of low-power and save electricity modules, TI''s MSP430 [2, 3] of the MCU, CC2500''s RF modules, Sensors and Timer, etc. modules. Wireless Sensor Networks is used DMAS [4] for the network topology architecture. According to the actual operation, the topology is more perfect, and analysis, adjust, improve the system. The system on the transmission data to avoid packet collision and interference noise, in order to enhance transmission efficiency. To reach the collection of sensing data, dynamic topology, scalability, fault tolerance, the load node of average energy consumption, energy-saving effect, etc. In addition, according to demand actually, the addition of solar power modules, as supplemented and auxiliary power supply.

The ecological monitoring system usually needs to monitor the targets for a long time, and acquires measured data steadily. Only contented with the conditions, the data just can be used to establish the ecological model. Therefore, this thesis presented an improved medium-access control protocol for wireless sensor network that aims to content with the characteristics of ecological monitoring, and it is applicable for a long-term monitoring and collecting reliable data. The proposed protocol adopted the concept of active/sleep mode in Sensor MAC (S-MAC). The sensor nodes used synchronization protocol to make nodes active/sleep synchronously. The protocol considered the number of network hierarchical levels and time slot assignment to plan the node working schedule during data transmission. It can improve the problem of data collision and idle nodes. Besides, the protocol monitored the situation of data loss while the wireless sensor network is transmitting data. When there were lost or un-transmitted data, the nodes uploaded the data by multi-paths to reduce the data loss and complete data collection. In order to keep the reliable connection of the wireless sensor network, the protocol demanded nodes to collect the information of the neighbors and found an alternative path when some nodes were out of power or damaged. Finally, we compared the designed protocol with S-MAC protocol in the power consumption, data stability and transmission latency. We also used the designed protocol in application of the oriental fruit fly monitoring system to examine the efficiency and functions.
