2003 journal article
Linking pollinator visitation rate and pollen receipt
American Journal of Botany, 90(11), 1612–1618.
TL;DR:
A direct positive link between pollinator visitation rate and pollen receipt is suggested across naturally varying floral morphology in Ipomopsis aggregata, a hummingbird-pollinated plant.

IMPACT OF NECTAR ROBBING ON ESTIMATES OF POLLEN FLOW: CONCEPTUAL PREDICTIONS AND EMPIRICAL OUTCOMES
Ecology, 84(2), 485–495.
TL;DR:
The indirect effects of the nectar-robbing bumble bee, Bombus occidentalis, on the distance of pollen movement among plants and levels of pollenmovement within plants are experimentally tested.

2003 journal article
THE ROLE OF HERBIVORES IN THE MAINTENANCE OF A FLOWER COLOR POLYMORPHISM IN WILD RADISH
Ecology, 84(7), 1733–1743.
TL;DR:
The data presented here suggest that differential preference and performance of herbivores for R. sativus color morphs may counter selection on flower color exerted by pollinators.

2003 journal article
Potential causes of population declines in forest fragments in an Amazonian frog
BIOLOGICAL CONSERVATION, 111(2), 205–214.
author keywords: forest fragmentation; Colostethus stepheni; Amazonian Brazil; population decline; survival probability; clutch size; population simulations
TL;DR:
Investigation of potential causes of declines in forest fragments for an Amazonian forest frog at an experimental fragmentation study site in central Amazonian Brazil finds that a reduction in clutch size is sufficient to cause the observed magnitude of population declines in fragments.

2003 journal article
Of mice and men and trillium: Cascading effects of forest fragmentation
ECOLOGICAL APPLICATIONS, 13(5), 1193–1203.
author keywords: demography; edge effects; habitat fragmentation; direct and indirect effects; landscape ecology; Pacific Northwest, USA; Peromyscus maniculatus; plant-animal interactions; population dynamics; trillium recruitment, southwest Oregon, USA
TL;DR:
Forest fragmentation has favored mouse populations, resulting in increased seed predation that may decrease recruitment rates and increase local extinction risks for trillium, which led to mouse densities 3-4 times higher at forest-fragment sites than at unfragmented sites.

2003 journal article
Landscape location affects genetic variation of Canada lynx (Lynx canadensis)
MOLECULAR ECOLOGY, 12(7), 1807–1816.
author keywords: biogeography; landscape ecology; landscape genetics; Lynx canadensis; microsatellite; population genetics
MeSH headings : Alleles; Animals; Carnivora / genetics; Demography; Electrophoresis, Polyacrylamide Gel; Genetic Variation; Genetics, Population; Geography; Heterozygote; Microsatellite Repeats / genetics; North America
TL;DR:
It is shown that peripheral populations of lynx have fewer mean numbers of alleles per population and lower expected heterozygosity, which is surprising, given the lynx's capacity to move long distances, but can be explained by the fact that periphery populations often have smaller population sizes, limited opportunities for genetic exchange and may be disproportionately affected by ebbs and flows of species’ geographical range.

2003 journal article
Identification of mustelids using mitochondrial DNA and non-invasive sampling
CONSERVATION GENETICS, 4(2), 241–243.
author keywords: fisher; Gulo gulo; hair snares; Martes; mitochondrial DNA; mtDNA; mustelids; non-invasive sampling; wolverine
TL;DR:
Non-invasives sampling of hairs left on hair snares can substan-tially increase the detection of elusive and secretive species and help make basic conservation decisions on listing, delisting, or threat status.

Corridor use by diverse taxa
ECOLOGY, 84(3), 609–615.
author keywords: biodiversity; bird; butterfly; conservation; corridors; dispersal; fragmentation; frugivory; landscape experiment; movement; pollination; small mammals
TL;DR:
The results show that movements of disparate taxa with broadly different life histories and functional roles are directed by corridors, causing higher movement between connected than between unconnected patches.

Spatial heterogeneity, not visitation bias, dominates variation in herbivory
ECOLOGY, 84(8), 2214–2221.
author keywords: herbivory; herbivory uncertainty principle; observer effect; plant performance; spatial heterogeneity; visitation effect
TL;DR:
It is proposed that future studies of herbivory will gain more by evaluating spatial heterogeneity in interaction outcomes than by quantifying possible experimenter-caused variation.

2003 journal article
Predicting which species will benefit from corridors in fragmented landscapes from population growth models
AMERICAN NATURALIST, 161(5), 808–820.
author keywords: conservation; corridor; model; metapopulation
MeSH headings : Conservation of Natural Resources; Ecosystem; Emigration and Immigration; Environment; Models, Biological; Time Factors
TL;DR:
A model of two logistically growing populations connected by migration in which both emigration and migration success were determined by the presence or absence of a corridor found that in the short run, corridors are most effective for species with fast‐growing populations that have low survivorship when dispersed through unsuitable habitat.
