A new species of Eiphosoma Cresson, 1865 (Hymenoptera, Ichneumonidae) is described based on five specimens collected in organic crops areas in Araraquara and Cravinhos municipalities, São Paulo State, Brazil. A diagnostic key to the neotropical Eiphosoma dentator species-group is also provided.
This paper explores how the social landscape of the latter half of the nineteenth century influenced D. D. Palmer and the many occupations he pursued. It focuses on the geographical area where D. D. lived from 1865 to 1898. This paper will show how the American social and economic events of the time provided favourable circumstances for D.D.'s entrepreneurial successes.

We nd large di¤erences in size and funding across NGOs, with only a few NGOs attracting most of the funding. Most NGOs are small and underfunded and focus on raising awar...
We investigated phylogenetic relationships among pond skaters (Heteroptera: Gerridae) of the genus Limnogonus Stål 1868 by performing separate and combined parsimony analyses of DNA sequences from three mitochondrial (COI+II, 16SrRNA) and one nuclear (28SrRNA) gene(s). The taxon sample represented almost two thirds of the known diversity, and with most taxa represented by two or more individual...
l. A simple technique was developed for accurately predicting the biomass of the freshwater prosobranch Viuiparus contectoides (Mesogastrapoda: Viviparidae) (Binney, 1865). 2. Regression of dry weight (biomass) on wet weight yielded a regression coefficient (r’) of 0.99 with an associated P < 0.001. 3. Biomass, therefore, can be predicted by measuring wet weights without sacrificing specimens.
