Averting biodiversity collapse in tropical forest protected areas
TLDR
These findings suggest that tropical protected areas are often intimately linked ecologically to their surrounding habitats, and that a failure to stem broad-scale loss and degradation of such habitats could sharply increase the likelihood of serious biodiversity declines. Expand
SPECIATION IN NORTH AMERICAN CHICKADEES: I. PATTERNS OF mtDNA GENETIC DIVERGENCE
TLDR
Phylogenetic analyses suggest that North American taxa include two clades, hudsonicus‐rufescens‐sclateri versus carolinensis‐atricapillus‐gambeli and thatCarolinensis and atricapilli are not sister species. Expand
The Sizes of Vertebrate-Dispersed Fruits: A Neotropical-Paleotropical Comparison

  • 1 November 1993
TLDR
In eight pantropicai, endozoochorous plant families, the Old World representatives tended to have more taxa with larger fruits than the New World representatives, which suggests that the evolution of large fruits and seeds might be more tightly constrained in the Neotropics owing to the relative scarcity of large frugivores there. Expand
Earth history and the passerine superradiation
TLDR
Recon reconstructing passerine evolutionary history and producing the most comprehensive time-calibrated phylogenetic hypothesis of the group, which suggests more complex mechanisms than temperature change or ecological opportunity have controlled macroscale patterns of passerine speciation. Expand
Distance and non-randomness of seed dispersal by the dwarf cassowary Casuarius bennetti
TLDR
This population of Aglaia would probably contract downhill into smaller, fragmented populations in the absence of cassowary-mediated dispersal, creating high densities near source trees that quickly tapered off near parent trees. Expand
The response of a New Guinean avifauna to conversion of forest to small-scale agriculture
TLDR
It is suggested that most species reacted moderately to habitat changes currently occurring, and this may be due in part to the fact that only a small proportion of the landscape at CMWMA has been converted to agriculture. Expand
An Advantage of Large Seed Size: Tolerating Rather than Succumbing to Seed Predators1
TLDR
Observations of viable seedlings with heavily damaged cotyledons suggest that these species withstand attack by rodents and beetles by virtue of their large size, suggesting that large-seeded species clearly have more than the minimum-required cotYledonary reserves. Expand
A Passerine Bird's Evolution Corroborates the Geologic History of the Island of New Guinea
TLDR
Evidence from this research suggests that different phylogeographic mechanisms concurrently structure lineages of C. megarhyncha and are not mutually exclusive, a result of evolutionary forces acting at different temporal and spatial scales concordant with New Guinea's geological history. Expand
LOW-FREQUENCY VOCALIZATIONS BY CASSOWARIES (CASUARIUS SPP.)
Abstract Although some birds can detect wavelengths in the infrasound range, there has been litle evidence that birds produce very low frequencies. We made nine recordings of a captive DwarfExpand
The Potential Impact of Small-Scale Physical Disturbance on Seedlings in a Papuan Rainforest1
TLDR
Artificial seedlings in clusters experienced significantly less damage than single ones, suggesting clustered seedlings might be less vulnerable to damage than lone seedlings. Expand
