The effects of invasive nonnative species on community composition are well documented. However, few studies have determined the mechanisms by which invaders drive these changes. The literature indicates that many nonnative plant species alter light availability differently than natives in a given community, suggesting that shading may be such a mechanism.(More)
To link spatial patterns and ecological processes, we analysed the distribution of two shrub species (one large and dominant, the other smaller) and estimated the reproductive consequences of their distribution for the smaller species. We tested the significance of the spatial distribution pattern of the two shrubs by second-order bivariate point pattern(More)
Printed on 100% recycled post-consumer waste with vegetable based inks. Summary Poverty and hunger continue to be widespread in India. The majority of these hungry and poor people live in rural areas, with a livelihood dedicated to agriculture. Some 86% of Indian farmers are smallholders, of less than 5 acres (2 hectares). About 65% have rain-fed farms(More)
One-way facilitation in plants has been found in many harsh environments and their role as structural forces governing species composition in plant communities is now well established. However, reciprocal positive effects benefiting two interacting species have seldom been reported and, in recent reviews, conceptually considered merely as facilitation when(More)
