New species and records of Rhyssa and Rhyssella (Hymenoptera: Ichneumonidae: Rhyssinae) from Florida and Central America [PDF]
, 2001 Rhyssa neotropicae n. sp. is the first Rhyssa to be recorded from the New World tropics, where it was collected in cloud forest at 1800 m on Monte Uyuca near Zamorano, Honduras. It is closely related to the Nearctic R. hoferi Rohwer and R.

Oikos, EarlyView.Speciation, extinction, and dispersal are the historical processes influencing the spatial distribution of lineages and strongly influence diversity patterns. Here, we apply a recently developed methodological approach to quantify the relative legacies in situ diversification history (i.e.

Stratified sampling enhances the understanding of bat–fruit networks in the southern Atlantic Forest
Oikos, EarlyView.Few studies have sought to understand the vertical patterns of bat–fruit systems, and therefore, it is not possible to evaluate whether interpretations based on data collected from a single stratum adequately represent the interaction patterns of this system. In this context, we evaluated the dissimilarity in the assemblage of frugivorous bats, plants,

New species and records of Anacis (Hymenoptera: Ichneumonidae: Cryptini) from tropical and temperate Andean South America [PDF]
, 2003 Descriptions are given of the new species Anacis ignifera and A. flammigera from Mérida State, Venezuela and of A. umbrifera from Machu Picchu, Perú. These belong to a tropical Andean lineage with strongly projecting propodeal cristae and pictured wings.

Floral resource diversity drives spatiotemporal variation in plant–pollinator network structure
Oikos, EarlyView.Mechanisms underlying community assembly, including those related to species interactions, vary across space and time. Plant–pollinator networks exemplify these dynamics, where link rewiring and turnover mediate adaptations to environmental changes. Bees rely on diverse floral resources (e.g.

Oikos, EarlyView.Accurate functional trait data are essential for understanding ecosystem services and processes in fragmented landscapes. We evaluated whether the global EltonTraits 1.0 database adequately represents the functional structure of mammal communities in forest fragments and restoration sites in a highly fragmented Atlantic Forest landscape.

Aspects of genetic and morphological variation in selected new world land birds [PDF]
, 2000 Thesis (M.S.) University of Alaska Fairbanks, 2000The objective of this thesis is to examine variation in certain New World land birds, focusing on morphological difference at the intraspecific level and genetic differences at the intra- and ...
