Climate and habitat
Habitat: tropical/subtropical dry broadleaf forest
Substrate: lake bottom/stream bed
Disturbance: grazing
Habitat comments: "tropical montane cloud forest... The regional climate includes three main seasons throughout the year: a humid-cold season (locally known as ‘nortes, ’ November–March), a dry season (April–June), and a rainy season (July–October)"; habitats are > 68% forest but also include pasture and a small amount of coffee plantation
Life forms: odonates
Sampling methods: line transect, other nets
Sample size: 94
Years: 2010
Seasons: dry, wet or monsoon
Sampling comments: "Water samples were collected during the dry (April) and rainy (October) seasons of 2010. In each stream, a 100-m transect traversing pools and riffles was established for sampling water and Odonata larvae... For each sample, a 500-lm-mesh D-frame (45 9 12 cm) aquatic net was swept three times across a 1 m2 area"
