These interactions can come from predators, parasites, competitors, and even mutualists. Here I test the hypothesis that pollination behaviors thought to expend more energy, may in fact be beneficial to the pollinator in terms of provisioning more resources for their progeny, as well as host plant. My study system is the obligate mutualism between two species of Joshua tree (Yucca brevifolia and Yucca jaegeriana) and their associated moth pollinators (Tegeticula synthetica and Tegeticula antithetica). I reconstructed sibships among pollinator larvae using DNA barcoding and microsatellite genotyping to infer instances in which female yucca moths had likely cross pollinated. I show that fruit seed and larvae totals were not significantly different between fruits that were a result of cross pollination and those that were not. I used regression modeling to see if the number of pollinator larvae influenced the number of seeds after accounting for climate variables. Here I saw a significant negative impact on seed totals, but also a strong effect from co-occurring seed predators. Other factors are likely to play a role in pollinators' return on investments which were unable to be incorporated for this study. These results are consistent with other studies demonstrating that moth interests are not in alignment with their host plant.

Deserts appear very fascinating during our short visits. However, the lives of plants and animals are very dif?cult under the harsh climatic conditions of high tempe- ture and scant water supply in deserts, sometimes associated with high concent- tions of salt. The editor of this book was born and brought up in the Great Indian Desert, and has spent much of his life studying the growth and metabolism of desert plants. It is very charming on a cool summer evening to sit at the top of a sand dune listening only to blowing air and nothing else. It has been my dream to prepare a volume on desert plants encompassing various aspects of desert plant biology. In this book, I have tried to present functional and useful aspects of the vegetation resources of deserts along with scienti?c input aimed at understanding and impr- ing the utility of these plants. The scant vegetation of deserts supports animal life and provides many useful medicines, timber and fuel wood for humans. Therefore, there are chapters devoted to medicinal plants (Chap. 1), halophytes (Chaps. 13, 14), and fruit plants (Chaps. 17, 20). Desert plants have a unique reproductive biology (Chaps. 9–11), well-adapted eco-physiological and anatomical charact- istics (Chap. 7), and specialised metabolism and survival abilities. These plants are dif?cult to propagate and pose many problems to researchers developing biote- nological approaches for their amelioration (Chaps. 18–20).

This book was released on 2011-08-18. Insect Ecology available in PDF, EPUB and Kindle. Combining breadth of coverage with detail, this logical and cohesive introduction to insect ecology couples concepts with a broad range of examples and practical applications. It explores cutting-edge topics in the field, drawing on and highlighting the links between theory and the latest empirical studies. The sections are structured around a series of key topics, including behavioral ecology; species interactions; population ecology; food webs, communities and ecosystems; and broad patterns in nature. Chapters progress logically from the small scale to the large; from individual species through to species interactions, populations and communities. Application sections at the end of each chapter outline the practicality of ecological concepts and show how ecological information and concepts can be useful in agriculture, horticulture and forestry. Each chapter ends with a summary, providing a brief recap, followed by a set of questions and discussion topics designed to encourage independent and creative thinking.
