In order to understand the implications of agriculture on the environment, ecosystem health must be measured. Observing the presence of a biological indicator within an ecosystem is one such method. In this study, male euglossine bees were observed using

Dalechampia brownsbergensis and D. fragrans co‐occur in Suriname, and both are pollinated by fragrance‐collecting male euglossine bees. Dalechampia brownsbergensis appears to bloom year‐round and is pollinated by relatively few species of bees, including Euglossa tridentata and E. gaianii. In contrast, D.

Although bees are important pollinators in several ecosystems around the world, studies on bee diversity in hygrophilous forests are scarce. This type of vegetation is restricted to permanently wet soils and, therefore, has particular floristic ...

Recognizing Indoor Scenes [PDF]
We propose a scheme for indoor place identification based on the recognition of global scene views. Scene views are encoded using a holistic representation that provides low-resolution spatial and spectral information.

The scaling of carbon dioxide release and respiratory water loss in flying fruit flies (Drosophila spp.) [PDF]
By simultaneously measuring carbon dioxide release, water loss and flight force in several species of fruit flies in the genus Drosophila, we have investigated respiration and respiratory transpiration during elevated locomotor activity.

Pollinating animals in the urban environment [PDF]
Urban environments contain habitats for flowering plants and their pollinating animal species. It is, however, unclear how the urban matrix influences plant-pollinator processes. We recorded plant diversity, floral abundance, flower visitor diversity and
