PERIPHYTIC DIATOMS OF LAKES WITH DIFFERENT TROPHIC STATE IN THE DEPARTMENT OF CAUCA (COLOMBIA)
SANDRA MORALES VELASCO,MARGARITA SALAZAR SáNCHEZ
Luna Azul , 2012,
Abstract: The presence and absence of Phyto-periphytic species have been used as indicators of trophic state of the aquatic systems, among which diatoms are emphasized. That situation and the lack of information for the department of Cauca, brought to the evaluation of three lakes with different trophic state and the performance of a adhered periphyton scrape in the plates established .. Samples were taken form the internal, medium and outer parts of each plate. The collected sample was preserved in Lugol-acetic acid. The lakes showed differences in the physicochemical characteristics of water, which determined the trophic state of each. According to this, the established ranges for nitrites, nitrates and total phosphorus, typified Lake 1 as oligotrophic, Lake 2 as meso-oligotrophic and Lake 3 as eutrophic. Diatoms predominated in all lakesbut the Lake 3 differs from the other lakes in the high dominance of the number of species and greater abundance of Gomphonema, a condition that is reflected in low values for Pielou equitability index.

Abstract: El agua es la base para los procesos productivos, no debe presentar riesgo de contaminación física, química o microbiológica en niveles que pongan en peligro el bienestar de los animales y la producción de leche cruda; condición que ha llevado al gobierno nacional a través de los Ministerios de Agricultura y Ministerio de Trabajo y de Seguridad Social (Viceministro de Salud) a realizar controles en los hatos lecheros. La Cooperativa de Productos Lácteos de Nari o COLACTEOS, muestreó 10 fincas proveedoras, determinando que el 90% no presentan sistemas de tratamiento y potabilización; y los problemas críticos se generan por ausencia de prácticas de manejo de las fuentes abastecedoras de agua y la relación con el sistema de producción.

Abstract: morphological characterization was performed of 114 accessions of tadehagi triquetrum from thailand, vietnam, china, indonesia and papua new guinea. the plant material is part of genebank fodder program of the international center for tropical agriculture (ciat). these accessions are used in animal feed and initially were sown in the greenhouse of ciat forage program palmira and after 8 weeks were transplanted to the final location on the grounds of the ciat experimental substation santander de quilichao. each accession was planted in a row of three plants, which were subjected to qualitative and quantitative descriptions of each of the organs of the plant (leaves, stem, inflorescence, flower, fruit and seed). during the morphological description of the accessions were three types of leaves in the form, oblong, ovate and oblong, ovate between. there were also three types of growth habit, erect, ascending and prostrate. it was also found that the species tadehagi triquetrum has compound leaves, pinnate with acute termination and winged petioles, stems with no branches simpondiales growing woody herb with simple racemose type inflorescences axial and terminal, complete with four flower whorls, hermaphrodites, stamens diadelphous cognates with an average of 10 per flower, the fruits are dehiscent legumes with an average of 4 seeds per pod which are characterized by three-dimensional with an average weight of 0.37 g per 100 seeds.

Abstract: given the low production of high quality fodder and environmental issues related to livestock at the regional level, this paper presents the results of research conducted in livestock production systems of tropical high cauca department, among the municipalities silvia, totoro, sotara and purace. the study aimed to establish a baseline of tree and shrub species with fitness forage utilization in beef production systems for cold climates department, dropping a line resulted in 17 families are currently being used by different arrangements livestock. la research systems developed from the recognition and primary data collection with the help of local producers, followed by the systematization and analysis for the identification of those species with higher occurrence and use. although there were a significant number of species, further study is necessary in some of these, since information about their phenological development and behavior in cattle production systems is still unknown. thus, the findings constitute a source of information for the design of livestock production systems more efficient in cold climates, while the basis for the formulation of future research proposals related to the field of agroforestry regional ecosystems.

Abstract: the originating effluents of the agro-industry of fique in the molino river of the group of judges of paniquitá (totoró-cauca) in three farms and four sites along river (1: of the aqueduct of paniquitá, 2: farm la esperanza, 3: el puente, 4: san josé bajo) generating handling alternatives. the results show that the polluting load for site 3 was the dbo5 (8,42 kg/día), sst (61,16 kg/día), the 4 registered a value of dbo5 (113,33 kg/día), sst (70,76 kg/ día) and the 1 presents/displays the characteristics of the birth of a river. for the three evaluated farms they registered values averages of dbo5 (3113,88 kg/día), sst (3673,13 kg/día).

Abstract: the cabbage (brassica oleracea) pest controlling effect of furcrea sp. extracts was evaluated a the 'la florida' forestal nursery of the corporación autónoma del cauca. four treatmens were applied (control, extract solutions at 30, 20 and 10 v/v %. plant vigour, height, pest and disease damage data were collected during a six weeks period. the extract applications were made once during the first three weeks, and the three following applications were twice a week. results were analyzed by an anova (p < 0,05) and a tuckey test, using spss15. the analysis reveals that the 30 v/v % furcraea solution applied twice a week resulted as the best pest control method minimizing damage by pieris sp., plutella xylostella, brevicoryne brassicae and myzus persicae.

Abstract: given the environmental effects of the different product for economic human activities, a cattle farming today warrants a new approach in which productive resources are revalued trees and shrubs as key elements for the design of production systems more efficient and sustainable. this paper presents the results achieved in research conducted in livestock production systems of the patía river valley of the cauca department whose objective was to establish a baseline of tree and shrub species with fitness forage utilization in livestock systems and installation of a seed bank on site. the study was developed from the recognition and primary data collection with the help of producers in the area, followed by the systematization and analysis for the identification of those species with higher occurrence and use. as a result, a total of 29 species that are currently being used by different arrangements in livestock systems. from the baseline established in this paper proposes some agroforestry designs that can be implemented in livestock systems in the area, thereby constituting a source of information for the formulation of future research proposals related to the field of agroforestry in regional ecosystems.
