ENERGY, WATER, AND BROAD‐SCALE GEOGRAPHIC PATTERNS OF SPECIES RICHNESS
It is often claimed that we do not understand the forces driving the global diversity gradient. However, an extensive literature suggests that contemporary climate constrains terrestrial taxonomic… Expand
Niche conservatism as an emerging principle in ecology and conservation biology.
The diversity of life is ultimately generated by evolution, and much attention has focused on the rapid evolution of ecological traits. Yet, the tendency for many ecological traits to instead remain… Expand
Predictions and tests of climate‐based hypotheses of broad‐scale variation in taxonomic richness
Broad-scale variation in taxonomic richness is strongly correlated with climate. Many mechanisms have been hypothesized to explain these patterns; however, testable predictions that would distinguish… Expand
Spatial autocorrelation and red herrings in geographical ecology
Aim Spatial autocorrelation in ecological data can inflate Type I errors in statistical analyses. There has also been a recent claim that spatial autocorrelation generates 'red herrings', such that… Expand
PRODUCTIVITY AND HISTORY AS PREDICTORS OF THE LATITUDINAL DIVERSITY GRADIENT OF TERRESTRIAL BIRDS
The latitudinal diversity gradient is the largest scale, and longest known, pattern in ecology. We examined the applicability of three versions of the energy hypothesis, the habitat heterogeneity… Expand
Spatial species‐richness gradients across scales: a meta‐analysis
Aim We surveyed the empirical literature to determine how well six diversity hypotheses account for spatial patterns in species richness across varying scales of grain and extent. Location … Expand

Preface 1. Introduction 2. Data and methodology 3. Parasitoid species richness 4. Taxonomic composition and generalist versus specialist parasitoids 5. Host mortality and the impact of parasitoids on… Expand
Does herbivore diversity depend on plant diversity? The case of California butterflies.
It is widely believed that the diversity of plants influences the diversity of animals, and this should be particularly true of herbivores. We examine this supposition at a moderate spatial extent by… Expand
PRECISE SEX RATIOS IN HIGHLY INBRED PARASITIC WASPS
When Williams (1979) considered the question of adaptive sex ratios in out-crossed vertebrates he concluded that the evidence favored Mendelian (random, binomial) sex determination. This may be… Expand
Accumulation of native parasitoid species on introduced herbivores: a comparison of hosts as natives and hosts as invaders.
Herbivore species newly introduced into foreign locations (hosts as invaders) are often attacked by native parasitoid species. Here we compare the structure and diversity of 87 such parasitoid… Expand
