Ítem Comunidad de arañas tejedoras (Arachnida: araneae en fragmentos de bosque seco y premontano de la cuenca del Río Pance (Cali, Colombia)(Universidad del Valle, 2013-01-01) Muriel Triana, Natalia; Valderrama Ardila, Carlos Humberto; AsesorLas arañas, uno de los grupos de artrópodos más diverso en el mundo, éstas se pueden encontrar en un amplio espectro de escalas espaciales y temporales, por esta razón es importante tenerlas en cuenta en procesos de planeación y manejo ambiental. En el presente trabajo se describe la composición de la comunidad de arañas tejedoras en cuatro fragmentos de bosque en la cuenca del Río PanceÍtem Evaluación de la diversidad de arañas como indicadoras de la efectividad de las estrategias de restauración implementadas en el corredor biologico Barbas - Bremen, Filandia (Quindío-Colombia)(Universidad Icesi, 2014-01-01) Ortiz Movliav, Carolina; Vargas, William Gerardo; Asesor TesisSpiders are a diverse and abundant group in all terrestrial ecosystems. Their communities are influenced by the type of habitat, land use, and plant architecture, so they are well accepted in ecological and environmental studies. They are generalist predators that have a major impact on the regulation of herbivore populations, also they are easy to collect and identify. The objective of this research was to evaluate the effectiveness of restoration strategies implemented in biological corridors connecting the Barbas River Canyon and The Forest Preserve of Bremen (Filandia-Quindío), through the measure of the diversity of spiders. For this, samples were taken in three biological corridors “Los Monos”, “Las Pavas” and “Los Colibríes”, in two forest fragments, Barbas and Bremen and in a paddock near to the corridors. Sampling was conducted during day sessions, and during dry and rainy seasons over one year period, using three methods: hand collecting (Looking up and looking down), sweeping with entomological net and using a beating trap. After 96 sampling unites, 736 individual were identified grouped into 18 families and 126 morphospecies.Ítem New records and geographical distribution of ctenid spiders (Araneae: Ctenidae) in Colombia(Magnolia Press, 2013-09-05) Simo, MiguelThis study provides new records, geographical distribution extensions and a checklist of the current ctenids species in Co-lombia based on the review of four arachnological collections and published literature. A total of 15 new records for Cteni-dae in Colombia are reported; nine of these species are new records for the country and the distribution of the remaining six is expanded. The genus Centroctenus Mello-Leitão, 1929 (C. ocelliventer Strand, 1909) is recorded for first time in Colombia and Cupiennius coccineus (F.O. Pickard-Cambridge, 1901) for South America. Due to the strategic geographic position of Colombia, which is a transition zone between Southern and Central American biotas, species inventories in different localities are important to fill distributional gaps. The number of known species of ctenids in Colombia is in-creased from 16 to 25 and these data will be useful for future studies in taxonomy, systematics and biogeography of this family.
