Organiza??o comunitária de um encrave de cerrado sensu stricto no bioma Caatinga, chapada do Araripe, Barbalha, Ceará
Costa, Itayguara Ribeiro da;Araújo, Francisca Soares de;
Acta Botanica Brasilica , 2007, DOI: 10.1590/S0102-33062007000200004
Abstract: this paper describes the community organization of a cerrado area within the caatinga biome, semiarid northeast brazil, on the araripe plateau, barbalha municipality, ceará state. the phytosociological survey was carried out using the point-centered quarter method (200 points) and included plants with a minimum stem diameter of 3 cm at ground level. relative parameters of density, dominance and cover (vc) were calculated. these data were compared with other brazilian cerrado areas. the cerrado area had 2224 ind.ha-1 with 19.2 m2 ha-1 of basal area, which is lower than other cerrado areas in brazil. a total of 43 species in 28 families were found in the area. populations with greater density were miconia albicans, vismia guianensis and casearia grandiflora, represented by low, slender shrubs. byrsonima sericea and qualea parviflora had greater vc; these are widespread species in cerrado, in spite of increased dryness as is the case of araripe. shannon diversity index (h') was 2.88 nats. ind.-1 and equability (j') 0.77. the disparity of criteria makes a more precise comparative analysis difficult and this is discussed.

Abstract: this study investigated density, germinability and floristic composition of the soil seed bank in an area of caatinga (thorny deciduous woodland). random soil samples were collected in a single sampling at fazenda n?o me deixes, quixadá, ce, from litter (n=100), 0-5cm depth layer (n=100) and 510cm layer (n=80). the seedling emergence method was used to determine density and germination curve. the floristic composition was determined using seedling morphology. the total density of the bank was 807 seeds.m2 and specific densities were 352 seeds.m-2 (litter), 304 seeds.m-2 (0-5cm) and 108 seeds.m-2 (5-10cm). most of the seeds germinated between the first and fourth weeks: 91% (n=1278 ; litter), 88% (n=1061 ; 0-5cm depth) and 89% (n=307; 5-10 depth), but some seeds germinated for up to 14th week. we determined 40 different morphospecies. the germination of about 88% of the seeds between the first and fourth week suggests that most caatinga seeds germinate at the onset of the favorable season, probably losing dormancy, if it exits, during the dry season.

Acta Botanica Brasilica , 1999, DOI: 10.1590/S0102-33061999000100002
Abstract: is the "carrasco" on the ibiapaba plateau a unique plant formation? to answer this question the vertical height (except of climbers) and the stem basal diameter (from 3cm on) of woody plants were measured, and soil extracts (0-50 and 50-100cm depth) were taken from 100 random plots (10x10m) at jaburuna (3o54'34"s and 40o59'24"w, altitudes near 830m), municipality of ubajara, ceará state. data on climate, soil, diameter height, density, basal area, and physiognomy were compared with those surveyed by other researchers from the carrasco, caatinga, and cerrado in northeastern brazil. the carrasco occurs under an annual rainfall of between 668 and 1,289mm and temperatures from 22 to 24oc, on alic quartz sand soils, at altitudes between 700 and 900m: it has a larger density and a smaller basal area than the caatinga and the cerrado, small and similar diameters, and an average vertical height between 3,7 and 5,4m. it differs from the caatinga, cerrado (and cerrad?o) and secondary forest in many items of lhe ecotope, organization and physiognomy, thus being a unique plain formation, which can be characterized as a deciduous, high, closed, and unistratified shrubland intermingled by lianas, with an irregular canopy and sparse, emergent trees.
Physiognomy and structure of a caatinga with Cordia oncocalyx (Boraginaceae), a new type of community in Andrade-Lima's classification of caatingas
Costa, Rafael Carvalho da;Araújo, Francisca Soares de;
Rodriguésia , 2012, DOI: 10.1590/S2175-78602012000200003
Abstract: recently, the inclusion of physiognomies with cordia oncocalyx allem?o (boraginaceae) as a new type/unit within andrade-lima's classification of caatingas (alfpc) has been proposed. however, no study has quantitatively analyzed this proposal so far. in order to fill this gap, a phytosociological study was conducted in a caatinga with c. oncocalyx, and differences in structure and physiognomy in relation to compiled caatinga studies were verified. 1795 plants from 25 species and a total basal area of 35.26 m2 were found. c. oncocalyx and mimosa caesalpiniifolia benth. (fabaceae) had 48% of total importance index (iv). the physiognomy was characterized by the predominance of individuals of intermediate height (3?4 m) and the tallest ones accounted for the highest fraction of basal area. of the five species with highest iv, only one had high frequency among the species with highest iv in the compiled studies (16/35). only two of these compiled studies were comparable to the present study, and only one could be classified according to alfpc. a contrast between that study and the present one was found, as the first reports a dense community with high number of small diameter individuals accounting for most of the basal area. these findings suggest the suitability of including c. oncocalyx caatingas in low and medium caatinga forests as proposed in alfpc. however, the low number of comparable studies limits generalizations.

Acta Botanica Brasilica , 2003,
Abstract: Este trabalho objetiva conhecer a densidade, riqueza e curva de germina o do banco de sementes no solo em uma área de caatinga. Em uma única amostragem aleatória, no final da esta o seca (outubro/novembro/1999) dentro da área de 1ha, foram coletadas 100 amostras de solo na serrapilheira à profundidade de 05cm, e 80 amostras na profundidade de 5-10cm. A área estudada localiza-se na Fazenda N o Me Deixes (RPPN - Reserva Particular do Patrim nio Natural), município de Quixadá, CE. Foram calculadas a densidade de sementes e a curva de germina o do banco, pelo método de emergência de plantulas. Também foi feita a determina o da composi o florística baseada principalmente na morfologia das plantulas. A densidade total do banco foi 807 sem.m-2. Na serrapilheira, 0-5cm e 5-10cm foram encontradas 352 sem.m-2, 304 sem.m-2 e 108 sem.m2, respectivamente. Quanto à curva de germina o, mais de 88% das sementes germinaram nas quatro primeiras semanas, porém algumas sementes continuaram germinando por até 14 semanas. Foram determinadas 40 morfoespécies diferentes de plantulas. A germina o de cerca de 88% das sementes nas primeiras quatro semanas indica que a maioria das sementes da caatinga est o aptas a germinar no início das chuvas e possivelmente devem perder a dormência, se tiverem, no decorrer do período seco.

Abstract: this study is an attempt to understand consumers' perceptions regarding cause related marketing [crm]. the research findings were based on a survey of 200 consumers in the brighton area and published data. the research aim was focused on the consumers' perception of the alliance between corporations and non-profit organisations. the research found that consumers have a better perception of firms that work with charities and good causes than those that do not. they believe that the partnership between corporations and charities has an impact on the good of society. however, they are aware that corporations themselves benefit from this partnership. concerning good causes, consumers prefer to support those related to children. the researchers noticed that an individual connection with a cause might have considerable influence on consumer attitudes and behaviour in relation to a specific cause.

Abstract: corporate social responsibility strategy and competitive advantage are important issues for the contemporary discussion on corporations in society when taking into account social and environmental impacts. empirically, we can see that social responsibility strategies are associated with competitive advantages, such as attracting valuable employees as well as enhancing the company image and reputation. this paper presents a theoretical review that demonstrates the association between social strategy and competitive advantage through the formulation of social strategies that influence and are influenced by opportunities, resources, skills, corporation merits, industry structure and stakeholders. based on the literature and a case study of carrefour, a model is proposed for competitive advantages stemming from the formulation of social strategies, which are explained based on their elements and adaptation to societal expectations. this article seeks to enrich the discussion on the strategic management of social responsibility and contribute to the literature on corporate social responsibility as well as strategy and competitive advantage.
