Abstract:

We modeled forest productivity parameters by remote sensing metrics derived from a Landsat-8 image and four Aster elevation images in the mountain rainforest of Southern Ecuador. The validated model for annual litterfall accounted for 68 % in variation of productivity. The partial least square regression model has been predicted across the study area. Non-forest areas have been masked out (using the land cover classification of Göttlicher et al. (2009). Attention this is work in progress. For further information please contact.

Abstract:

The prediction map identifies the estimated richness of Pyraloidea species in the mountain rainforest in the San Francisco Valley. The corresponding regression model explained 72% in variation of species richness. Further information about the model and sampled field data are published in Wallis et al. (2017): Remote sensing improves prediction of tropical montane species diversity but performance differs among taxa. doi: 10.1016/j.ecolind.2017.01.022

Abstract:

Nocturnal moths were sampled on 20 plots during three periods between 1999 and 2000 using light traps equipped with two backlight 15 W tubes operated between 18:30 and 21:30 local time (UTC-5:00). Catches were restricted to periods from three days after full moon until five days before full moon. Specimens were sorted to morphospecies within geometrid moths (Geometridae). Data from the PHD-thesis of Dr. Gunnar Brehm. For additional information on methods and sites see: Brehm, G. (2002): Diversity of geometrid moths in a montane rainforest in Ecuador. PHD-thesis.

Abstract:

We measured LAL (leaf area loss) as an indicator for herbivory for 27 plots in natural and disturbed forest sites (1000 to 3000m a.s.l.). LAL (%) was estimated for the shrub layer and the herbal layer in 30 randomly chosen m² per plot. We averaged the LAL of both layers.

Abstract:

Abundance of ant species were collected during the wet and the dry season 2014 on the core plots and intermediate elevation levels (1000, 1500, 2000, 2500, 3000) on disturbed and undisturbed forest plots.

Abstract:

Ants data obtained by baiting with 6 used nutrients (water, salt solution, sugar solution, amino-acid solution, amino-acid-sugar solution, oil). Data were collected during the wet and the dry season 2014 on the coreplots and intermediate elevation levels (1000, 1500, 2000, 2500, 3000) on disturbed and undisturbed forest plots. The predation data were collected using an artificial caterpillar approach.
