1. Phenotypic similarity between fruits of Gevuina avellana (Proteaceae) and wasp-induced galls of Nothofagus dombeyi (Nothofagaceae) does not protect fruits from predation by rodents
ABSTRACT Fruits of Gevuina avellana (Proteaceae) seem to mimic wasp-induced galls of Nothofagus dombeyi (Nothofagaceae) to escape predation by rodents, which may change both spatially and temporarily. The objective of this study was to evaluate the similarity between the fruits of G. avellana and the galls of N. dombeyi and to determine if this similarity p

2. Differential response of microbial respiration to supplied nitrogen forms in 3 contrasting alpine meadow soils on the Tibetan Plateau
ABSTRACT An incubation experiment was conducted to examine the effects of nitrogen (N) applications in different forms (NH4NO3, NH4Cl, and KNO3) on microbial respiration considering 3 different alpine meadow soils (C poor soil, pH = 8.1, 1.6% C; C moderate soil, pH = 6.0, 5.0% C; C rich soil, pH = 7.1, 7.4% C) in the Tibetan Plateau. The addition of NH4NO3 a

3. Predatory behavior of the paguroid Dardanus venosus (H. Milne-Edwards, 1848) (Anomura: Diogenidae) on the snail Aurantilaria aurantiaca (Lamarck, 1816) (Gastropoda: Fasciolariidae)
Abstract Paguroids are usually detritivorous organisms and the occurrence of predation on mollusks is very unusual. This contribution reports the occurrence of a predatory behavior of the paguroid Dardanus venosus (H. Milne Edwards, 1848) on the snail Aurantilaria aurantiaca (Lamarck, 1816).

7. Proboscis Length and Resource Utilization in Two Uruguayan Bumblebees: Bombus atratus Franklin and Bombus bellicosus Smith (Hymenoptera: Apidae)
Bumblebees (Bombus sp.) are eusocial insects with an annual life cycle whose use as pollinator of crops has gained great importance in modern agriculture. Several authors have found that resource use in Bombus species is usually based on the correlation between the proboscis length of the bumblebees and the corolla depth of the flowers. The aim of this study
