| dc.description | Los cole?pteros son una biota relevante en la evaluaci?n de las cuencas hidrogr?ficas
porque proveen informaci?n importante sobre el estado de los ecosistemas y sus
din?micas. Una cuenca especial del departamento del Tolima es la del r?o Anchique,
inmersa en fragmentos de bosque seco, con presiones antropog?nicas marcadas. Dada
la importancia de dicha cuenca, se realiz? el presente estudio orientado a determinar la
composici?n y estructura de la fauna de cole?pteros en este cuerpo de agua. Se
realizaron seis muestreos distribuidos en cuatro estaciones y dos temporadas clim?ticas
contrastantes, a lo largo de la cuenca. Se analizaron variables fisicoqu?micas in situ y en
laboratorio se evaluaron otras variables fisicoqu?micas y bacteriol?gicas. Se colectaron
618 organismos correspondientes a ocho familias y veintid?s g?neros, siendo
Microcylloepus el m?s abundante (46.44%). A nivel temporal la mayor abundancia
relativa se registr? en julio de 2015 (35.41%) y la menor en abril de 2016 (6.96%). A nivel
espacial la estaci?n Nacimiento present? la mayor riqueza y la estaci?n Balneario la
mayor diversidad. En cuanto los par?metros fisicoqu?micos se detectaron relaciones
entre el g?nero Stenus con la demanda qu?mica de ox?geno, y del g?nero Laccophilus
con la turbidez. De acuerdo con las observaciones en campo, las estaciones con mayor
diversidad y abundancia presentaron variedad de sustratos y cobertura vegetal,
favoreciendo el establecimiento y colonizaci?n de las comunidades de cole?pteros en la
cuenca. Es importante resaltar que los cole?pteros acu?ticos encontrados en el presente
estudio son organismos que presentan especializaciones para colonizar diferentes
ambientes.

| dc.description | The Coleoptera is a relevant biota in assessing watersheds because they provide
important information about the state of ecosystems and their dynamics. A special
watershed of Departamento del Tolima is the Anchique river immersed in dry forest
fragments, and with marked anthropogenic pressures. Given the importance of this biota
and the hydrografic basin, this study aimed to determine the composition and structure of
the fauna of Coleptera in this w?ter body six samplings in four seasons and two
contrasting weather seasons were conducted throughout the hydrografic basin.
Physicochemical variables were analyzed in situ and laboratory, other physicochemical
and biological variables were evaluated. It was collected 618 organisms corresponding
to eight families and twebty two genus, being Microcylloepus the most abundant
(46.44%). About temporal sampling, the highest relative abundance was recorded in July
2015 (35.41%) and the lowest in April 2016 (6.96%). About space level the Nacimiento
station presented the greatest richness and the greatest diversity was obtained by
Balneario station. About physicochemical parameters were detected relationships
between gender Stenus with chemical oxygen demand, and gender Laccophilus with
turbidity. According to field observations, stations with greater diversity and abundance
presented variety of substrates and vegetation covering, favoring the establishment and
colonization of communities of Coleoptera in the basin. It?s important to note that water
coleoptera found in the present study are organisms that have specializations to colonize
different environments.
