Abstract:
... Pollination of the orchid Goodyera foliosa var. maximowicziana was studied during the autumn of 1995 and 1996 in Matsue, Japan. The flowers were rarely visited by 5 insect species, among which only the bumblebee Bombus diversus diversus, usually workers, was the legitimate pollinator. They received the pollinarium on the galea of proboscis. Nectar‐robbing ants frequently adhered to the viscidium o ...

Abstract:
... The anatomy and ultrastructure of floral nectary of Platanthera bifolia were studied. The epidermis inside the nectary spur showed characteristic features of secretory tissue. Many cells of this epidermis were protruded forming unicellular hairs. The protoplasts of secretory cells were characterized by few small vacuoles, a lot of mitochondria and leucoplasts, which stored starch before secretion. ...

Abstract:
... We observed 5 nectar-collecting behaviors of Diadegma insulare (Cresson), a major parasitoid of diamondback moth, Plutella xylostella (L.). The most striking behavior of D. insulare was chewing at the base of Barbarea vulgaris R. Br. and Brassica napus L. flowers and creating holes that probably released the floral nectar. D. insulare visited more frequently and spent longer times on flower specie ...

The combined effects of temperature (2-46 degrees C) and pH (1.55-6.25) on the growth of Candida pelliculosa isolated from guava nectar produced in Cameroon were studied using a turbidity method, ie measurement of optical density at 630 nm. A quadratic polynomial model was constructed to predict the effects and interactions of these two environmental conditions on the maximal optical density obtai ...

Abstract:
... We summarize data on the breeding biology (based on seven nests) of the White-tailed Sabrewing (Campylopterus ensipennis; Trochilidae) at Tobago, West Indies. Breeding occurred during the dry season (February–April). Nests were placed 1.75–11 m high in small dicot trees, bamboo and palms in the forest interior, usually near streams. Two white eggs were laid in bulky (7–35-cm high), cup-shaped nest ...

Abstract:
... Hurricanes can strip leaves from plants and provide other stresses that can reduce resource availability for subsequent reproduction. In addition, hurricanes commonly reduce populations of bird pollinators. I measured both resource and pollination limitation of fruit set for Bahama Swamp‐bush (Pavonia bahamensis) on San Salvador Island in the Bahamas before and after two seasons of hurricanes. Bef ...

We analyzed seasonal variation in avian species richness and relative abundance at the community and guild level during a 13-month period in central Bolivia in an 11-ha patch of Polylepis (Rosaceae) forest, a high-Andean ecosystem that has suffered from extreme anthropogenic fragmentation. Birds were surveyed audio-visually (supplemented with mist net data) and assigned to five relative abundance ...
