Article
Predation can effectively limit insect herbivores with cascading effects on plant community composition and diversity of tropical rainforests. Assessing variation in predation is therefore important to understand the mechanisms structuring complex rainforest ecosystems. Variation in predation with time of day may provide herbivores with temporal en...

Silicon (Si) has a variety of functions in plants, including alleviation of drought and light stress, defense against herbivores and pathogens, and improving plant nutrition. However, for tropical forests our knowledge about the role of silicon and its variation in soils and plants remains limited. To advance our insights into the potential role of...

One explanation for the extraordinarily high tree diversity of tropical lowland forests is that it is maintained by specialized natural enemies such as insect herbivores, which cause distance and density dependent mortality. Insect herbivory could also explain the positive correlation between tree species richness and rainfall if herbivory increase...

Biotic interactions underlie ecosystem structure and function, but predicting interaction outcomes is difficult.We tested the hypothesis that biotic interaction strength increases toward the equator, using a global experiment with model caterpillars to measure predation risk. Across an 11,660-kilometer latitudinal gradient spanning six continents,...

Comparative adult morphology of Coenagrion lunulatum, C. pulchellum, and C. puella in a syntopic situation (Odonata: Coenagrionidae) – Interspecific competition among odonate species for food, mating partner etc. is a common phenomenon. Because morphology mediates species' behaviour and microhabitat use, competition is expected to increase with spe...

By comparing saturniid & arctiniid communities to precipitation and woody-plant diversity data collected at several forest sites situated across the Isthmus of Panama, we evaluate whether changes caterpillar diet breadth provide support for the Janzen-Connell effect as a driver of precipitation-correlated gradients in woody-plant diversity, as well as improve our knowledge of local saturniid & arctiniid communities.
