Although mammals of Paleocene age are well known from Alberta, their record is largely restricted to one lithological unit, the Paskapoo Formation (a record that includes mammals from the Cochrane area erroneously attributed to the Porcupine Hills Formation). We report here the first occurrence of Paleocene mammals from the Porcupine Hills Formation at exposures near the western edge of the city of Calgary. The assemblage, termed the Bearspaw local fauna, documents a diversity of multituberculate and eutherian mammals, including new species of the pentacodontid Aphronorus bearspawensis sp. nov., the mixodectid Eudaemonema bohachae sp. nov., the hyopsodontid Promioclaenus thnetus sp. nov., and a new genus and species of multituberculate (Alopocosmodon hadrus gen. et sp. nov.) tentatively referred to the Microcosmodontidae. The Bearspaw local fauna also details the first Canadian occurrences of several taxa, including Ptilodus wyomingensis, Aphronorus fraudator, Bryanictis microlestes, Elpidophorus minor, and possibly Goniacodon. Preliminary biostratigraphic analyses suggest that the Bearspaw local fauna is middle Torrejonian (To2) in age, correlating most closely with near-coeval Gidley Quarry of Montana and Rock Bench Quarry of Wyoming. In addition to improving the depauperate record of Torrejonian mammals in western Canada, the new fauna is important in documenting a mammal assemblage from a lithological unit that is thought to have been deposited in semi-arid conditions, rather than the wetter and more humid conditions of the Paskapoo Formation. Further, the Bearspaw localities, along with several other recently discovered localities in the Calgary and Cochrane areas, closely bracket the 27n–26r chron boundary and as such will be important in detailing the Torrejonian–Tiffanian transition in western Canada.

The biodiversity and quality of subterranean waters were comparatively studied in the Tarf plain near Oum-El-Bouaghi and in the Ksar S’bahi in Oum-El-Bouaghi, in North-eastern Algeria. For this purpose, physicochemical and faunistic analyses were carried out on the water of ten stations located in the area of Tarf, and thirteen in the area of S’bahi. In the wells of Tarf, the average stygobiologic diversity was relatively high in the wells located upstream the dumping site from the city where the groundwater presented low contents of nitrates and orthophosphates. In contrast, the wells located in the spreading zone of Tarf wastewaters were characterized by the scarcity or the absence of stygobic species; in these latter wells, the water was highly polluted. It was rich in nitrates, nitrites, ammonium, and the conductivity was rather high. In the area of S’bahi, the faunistic inventory recorded ten species, some of which were living in hot springs. The subterranean water was highly mineralized. In the two studied areas, biodiversity decreased when well water was locally polluted.

Resumo O crescimento urbano desordenado e sem planejamento tem contribuído para o surgimento de vários problemas socioeconômicos e ambientais, até mesmo em pequenas cidades localizadas no semiárido do Nordeste brasileiro. Objetivou-se com este estudo verificar as ineficiências e os desafios que norteiam a implantação do Plano Diretor Participativo do município de Ibimirim, estado de Pernambuco. O estudo em evidência é de caráter descritivo e exploratório complementando-se, para o alcance dos resultados propostos, com o método observacional. Foram feitas análises documentais e observações diretas em campo. Verificou-se que o Plano Diretor está composto por eixos e que algumas normas não estão sendo cumpridas conforme a legislação em vigor. O município não revisa o seu Plano Diretor desde o ano de 2006 e não existe fiscalização nas construções, devido à ausência de instrumentos, como o código de posturas, o código de obras e edificações e o zoneamento urbano-ambiental. Espera-se que esta observação possa subsidiar políticas públicas para uma regularização urbana e promoção de melhores condições de vida para as presentes e futuras gerações, neste e em outros municípios do semiárido. Palavras-chave: Urbanização. Estatuto das cidades. Plano Diretor. Ibimirim. Abstract The uncontrolled and unplanned urban growth has contributed to the insertion of several socioeconomic and environmental problems, even in small cities located in the semi-arid region of Northeast Brazil. The objective of this study was to verify the inefficiencies and challenges that guide the implementation of the Participatory Master Plan of the municipality of Ibimirim, state of Pernambuco. The study in evidence is descriptive and exploratory, complementing it in the proposed results' scope with the observational method. Documentary analyses and direct observations were made in the field. It was found that the Master Plan is composed of axes and that some standards are not being complied with according to the legislation in force. The municipality has not revised its Master Plan since 2006, and there is no inspection in the buildings due to the absence of instruments, such as the city administrative rules, the code of works and buildings, and the urban-environmental zoning. It is expected that this observation can support public policies for urban regularization and promotion of better living conditions for present and future generations, in this and other municipalities of the semi-arid region.

The Northwest of Algeria, characterized by a semi-arid climate has seen in recent decades its surface and ground water potential decrease due to the scarcity of rainfall. Demographic pressure has increased the difficulties in the management of water resources, leading to problems of water scarcity in several areas of the country, especially in low-rainfall areas. From the hydrogeological point of view, the study area contains many karstic springs with great importance, which flows can exceed 50 l /s during flood periods. Aquifer recharge occurs primarily by rainwater.The main objective of this study was to evaluate the water balance of the karst aquifer situated near the city of Saida (North-West of Algeria) and to follow its evolution on several decades. In this region, the karst groundwater is important for drinking water supply, irrigation and industrial units.This approach to assessment will be based on the water balance equation by involving precipitation, evapotranspiration, infiltration and groundwater flow. The total volume of the groundwater reserves obtained from the balance method represent 45 million m3. These reserves have decreased with time.

Objetivou-se avaliar neste trabalho a influência da variabilidade climática sobre a pluviometria local e, consequentemente sobre a produção agrícola, sobretudo das culturas de milho, feijão e mandioca, responsáveis pelas maiores atuações na renda dos agricultores familiares de Aiuaba (CE). Os resultados das Análises de Ondeletas apontaram ciclos de 5-6 anos (ENOS) para ocorrência de anos chuvosos, consequência da associação de diferentes escalas temporais, enquanto que em anos secos foram observados ciclos entre 4 e 6 anos (ENOS), mostrando que a escala de ENOS influencia em toda série de precipitação. Na falta de associação com as demais escalas temporais ocorreram anos secos. Correlações entre precipitação e todas as variáveis de produção apresentaram-se altas e com significância estatística, manifestando menores correlações apenas entre precipitação e área planta e colhida para a cultura da mandioca, únicas variáveis sem significância estatística. O presente estudo mostrou que as informações geradas para o município são proveitosas para os diversos setores como agrícola e socioeconômico. Notou-se também que a variabilidade climática tem efeitos substanciais na produção da agricultura familiar local.   A B S T R A C T In semi-arid regions such as the county of Aiuaba (CE) the agricultural productivity is more likely to be influenced by edaphoclimatic factors, what beyond of the importance of the producer’s technological level, also influence directly in agriculture. The objective this work was to evaluate the influence of climate variability on the local rainfall and consequently on agricultural production, especially of maize, beans and cassava, account for the greatest performances in the income of farmers of Aiuaba (CE). To reach these objectives were used statistical methods as Correlation and Analysis of Wavelet. The results of the Wavelet analysis pointed cycles of 5-6 years (ENSO) for the occurrence of rainy years, a consequence of several different temporal scales, while in dry years were observed cycles between 4 and 6 years (ENSO), showing that the ENSO scale influence on all series of rainfall. In the absence of association with other timescales occurred dry years. Correlations between rainfall and all production variables were high and with statistical significance, showing only small correlations between rainfall and plant and harvested area for cassava, only variables not statistically significant. This study showed that the information generated for the city are useful for various industries like agriculture and socioeconomic. It was also noted that climate variability has significant effects on the production of local family farmers. Keywords: Climate variability, Family farming, Correlation, Wavelets, ENSO.
