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
Tree and Liana Enumeration and Diversity on a One‐Hectare Plot in Papua New Guinea1
TLDR
L Lauraceae, Moraceae, and Myristicaceae were the most important families in both size classes of this species-rich site, which has high aseasonal rainfall and high rates of natural disturbance. Expand
First-Cohort Advantage Hypothesis: A New Twist on Facultative Sex Ratio Adjustment
TLDR
The first-cohort advantage hypothesis is proposed, which proposes that females will increase their fitness by producing more males than females in their first than in their second litters when first- cohort males have a mating advantage over second-coHort males. Expand
Diet, Keystone Resources and Altitudinal Movement of Dwarf Cassowaries in Relation to Fruiting Phenology in a Papua New Guinean Rainforest
I recorded plant community phenology for three years, classified each fruiting species according to pattern (continually, annually, biennially or one-year fruiting) and documented what cassowariesExpand
Notes on Occurrence and Feeding of Birds at Crater Mountain Biological Research Station, Papua New Guinea
TLDR
During 1989-93, 170 species of birds were observed and 1787 individuals captured in mist nets at the Crater Mountain Biological Research Station, Chimbu Province, Papua New Guinea, revealing striking similarities among sites in number of species and trophic organisation. Expand
The influence of nest availability on the abundance and diversity of twig-dwelling ants in a Papua New Guinea forest
TLDR
It is observed that ant species richness and abundance increased with natural twig density, at least for naturally occurring communities, while other biotic and abiotic factors likely influence the use of nesting habitat in these ant communities. Expand
The Vulturine Parrot, Psittrichas fulgidus , a threatened New Guinea endemic: notes on its biology and conservation
TLDR
Four possible conservation measures are suggested: (1) increase field studies; (2) restrict transport of live birds on domestic flights; (3) replace use of Psittrichas feathers with dyed chicken feathers; (4) instruct tourists not to purchase handicrafts containing PsittRichas or other animal parts. Expand
The Frugivore Community and the Fruiting Plant Flora in a New Guinea Rainforest: Identifying Keystone Frugivores
TLDR
Cassowaries appear to be a keystone frugivore, especially for large-fruited plant species (67 species > 50 g at the study site), and further life history studies are recommended for confirmation of f importance when using this method. Expand
Differential effects of mammalian seed predators on the regeneration of five Papua New Guinean tree species and implications for sapling recruitment
TLDR
Investigating the relative effects of seed predation on the regeneration of five tree species in a mid-elevation Papua New Guinean rain forest found that the species-specific influence of mammalian seed predators correlated with abundance distributions in three life stages. Expand
