15 صفحه اولDistances, Assumptions and Social Wasps
The use of distance data in phylogenetic inference retains adherents in molecular systematics, despite the well-established cladistic critique of distances. Molecular distance matrices have been supposed to measure evolutionary divergence; however, trees based upon analyses of such matrices are generally uninterpretable as doing so-under realistic conditions (Farris, 1981, 1985, 1986). In addit...
متن کاملThe Overlooked Biodiversity of Flower-Visiting Invertebrates
Estimates suggest that perhaps 40% of all invertebrate species are found in tropical rainforest canopies. Extrapolations of total diversity and food web analyses have been based almost exclusively on species inhabiting the foliage, under the assumption that foliage samples are representative of the entire canopy. We examined the validity of this assumption by comparing the density of invertebra...

There is a huge diversity of garden plant varieties, and some recommendations are available as to which are attractive to insects. However, these are largely not based on rigorous empirical data. An important factor in consumer choice is the range ...
