Bamboo was characterized as having a high green vegetation (GV) fraction, lower non-photosynthetic vegetation (NPV) and a low shade fraction, while pine exhibited higher NPV and shade fractions.
We tested if bat and/or bird exclusion from cacao trees leads to higher arthropod abundance and leaf damage, and conducted the experiment in high and low shade plantations.
During the dry season and rainy season of 2011 we sampled ground active spiders using pitfall traps from high and low shade coffee agroecosystems (27 sites) and from forest (10 sites).
For example, trees with high shade tolerance responded faster to cold temperatures by changing colours more quickly than trees with low shade tolerance.
In the Western Region of Ghana, the majority of cacao farms are now predominantly being managed with low shade or no shade [11, 12].
Richness of forest bats was the same across all land-use types; in contrast, species richness of open-space bats increased in low shade, intensively managed coffee plantations.
We conclude that diverse shade coffee plantations in our study area serve as valuable foraging and commuting habitat for aerial insectivorous bats, and several species also commute through or forage in low shade coffee monocultures.
The importance of this relationship was probably accentuated by taking site means for both predictor and response variables because sites were characterized by being either high shade (forests) or low shade (clear-cuts).
Reduced levels of foraging activity in the most intensive plantations for both forest and open-space bats suggest that low shade coffee monocultures may serve more as commuting than foraging habitat.
Occasionally, one or more individuals showed hypervariable measurements over time (triglyceride levels for CHD-8; Figure 1B), but for the purposes of clinical risk evaluation, average values reflect the rank order of individuals, and are sufficient to place individuals in broad categories, from very low (light blue shading) to very high (pink).
