1. Diameter Increment Modeling in an Araucaria Forest Fragment Using Cluster Analysis
ABSTRACT The aims of the present study were to test the hypothesis that data stratification by cluster analysis and the use of other variables, in addition to DBH, can improve the precision of the estimates in diametric increment modeling for Mixed Ombrophilous Forest species. The study was carried out in the Irati National Forest. Data from 25 permanent sa

2. How specialists can be generalists: resolving the "parasite paradox" and implications for emerging infectious disease
The parasite paradox arises from the dual observations that parasites (broadly construed, including phytophagous insects) are resource specialists with restricted host ranges, and yet shifts onto relatively unrelated hosts are common in the phylogenetic diversification of parasite lineages and directly observable in ecological time. We synthesize the emergin

3. A comunidade de esfingídeos (Lepidoptera, Sphingidae) e plantas esfingófilas numa área de cerrado no sudeste do Brasil: biogeografia e associações mutualísticas / The hawkmoth (Lepidoptera, Sphingidae) and hawkmoth-flower plant community in a Cerrado area of southeastern Brazil: biogeography and mutualistic associations
Hawkmoths (Lepidoptera, Sphingidae) are among the major pollinators in tropical communities. However, in the Cerrado biome little is known about their distribution, species composition, diversity, as well as, their relationships with hawkmoth-flower plant flora. This study aim to describe the hawkmoth fauna and hawkmoth-pollinated plant flora of a Cerrado ar

4. A comunidade de esfingÃdeos (Lepidoptera, Sphingidae) e plantas esfingÃfilas numa Ãrea de cerrado no sudeste do Brasil: biogeografia e associaÃÃes mutualÃsticas / The hawkmoth (Lepidoptera, Sphingidae) and hawkmoth-flower plant community in a Cerrado area of southeastern Brazil: biogeography and mutualistic associations
As mariposas da famÃlia Sphingidae estÃo entre os principais polinizadores em comunidades tropicais. PorÃm, no bioma Cerrado pouco se conhece sobre a sua distribuiÃÃo, composiÃÃo, diversidade, assim como, suas relaÃÃes com a esfingÃfila da regiÃo. Neste estudo nÃs descrevemos a fauna de esfingÃdeos e a flora de plantas esfingÃfilas para uma Ãr

5. The integration of GPS, vegetation mapping and GIS in ecological and behavioural studies
Global Positioning System (GPS) satellite navigation receivers are increasingly being used in ecological and behavioural studies to track the movements of animals in relation to the environments in which they live and forage. Concurrent recording of the animal's foraging behaviour (e.g. from jaw movement recording) allows foraging locations to be determined.

6. The Effects of Interspecific Competition on the Dynamics of a Polymorphism in an Experimental Population of DROSOPHILA MELANOGASTER
Populations of Drosophila melanogaster with a fourth-chromosome polymorphism were subjected to different levels of competition with Drosophila simulans. The dynamics of the polymorphism and the equilibrium frequencies of the sparkling allele were seen to depend on the competitive level, while the higher productivity of the competing populations was shown to

7. Inferring Patterns of Migration from Gene Frequencies under Equilibrium Conditions
A new maximum likelihood method to simultaneously estimate the parameters of any migration pattern from gene frequencies in stochastic equilibrium is developed, based on a model of multivariate genetic drift in a subdivided population. Motivated by simulations of this process in the simplified case of two subpopulations, problems related to the nuisance para
