Pollination Ecology in the Southwest

Pollination Ecology in the Southwest

Pollination ecology and the possible impacts of environmental change in the Southwest Australian Biodiversity Hotspot.

The Southwest Australian Biodiversity Hotspot contains an exceptionally diverse flora on an ancient, low-relief but edaphically diverse landscape. Since European colonization, the primary threat to the flora has been habitat clearance, though climate change is an impending threat. Here, we review (i) the ecology of nectarivores and biotic pollination systems in the region, (ii) the evidence tha...

A Study on the Pollination Ecology of Eremurus inderiensis

Two-year study on the pollination ecology of Eremurus inderiensis reveals that the florescence of eremurus is from the middle ten days of May to the first ten years of June, anthesis of a single flower lasts one day. When the weather is rainy and the highest temperature is less than 20 centigrade, anthesis of a single flower can last two days. Pollen dispersal period of single flower can last f...

Pollination ecology of the rare desert species Eremosparton songoricum (Fabaceae)

The pollination ecology of Eremosparton songoricum (Litv.) Vass., a rare desert species endemic to central Asia, was examined by a series of observational studies and manipulative experiments in two natural populations during 2007–2008. Results showed that the duration of flowering lasted 21 and 23 days, respectively, in Populations A and B from late May to late June in 2008. Anthesis of a sing...

Pollination ecology of Disterigma stereophyllum (Ericaceae) in south-western Colombia.

Several authors have recently expressed doubts that the 'pollination syndromes' as usually expressed are an adequate description of correlated suites of floral characters, or that they adequately describe evolutionary or ecological associations of plants with pollinators. Disterigma stereophyllum is a neotropical Ericaceae with floral characteristics intermediate between the 'entomophilous' syn...
