1. Emergence of Razor Grass on the Basis of Origin and Seed Depth in the Soil Profile
RESUMO: O capim-navalha ( Paspalum virgatum L.) é uma planta daninha de pastagens que tem ganhado importância devido à elevada capacidade de multiplicação por sementes, principalmente quando se faz necessária a reforma. O entendimento do comportamento da emergência de plântulas é de fundamental importância para a adoção de estratégias de manejo

2. Estádio de maturação dos frutos, tratamentos pré-germinativos e variabilidade da emergência de plântulas de morototó (Schefflera morototoni)
The objective of this work was to evaluate the influence of the fruit maturation stage in the physical attributes and germination of Schefflera morototoni pyrenes subjected to pre-germination treatments. Fruits with green and purplish green coloration were collected from 14 individuals, pulped in running water, the hollow pyrenes were discarded after countin

3. Variabilidade de cinco espécies arbóreas da região de cerrado do Brasil Central para medidas de germinação e emergência / Variability of five arboreous species of the Central Brazil cerrado region for germination and emergency measurements
Basic studies of seed germination and seedling emergence assume an important role within scientific researches due to the devastation and fragmentation of the native vegetation of the Cerrado. Thus, in the present study the processes of seed germination and seedling emergency were evaluated using the linear correlations among the measurements calculated for

5. Padrões de diversidade e organização temporal de Chironomidae (Diptera) em um córego tropical
In this study we investigated the temporal dynamics of a chironomid assemblage in a forested stream located in southeastern Brazil. First, we analyzed some diversity patterns of this assemblage by describing two macroecological relationships (body size-species richness and body size-abundance) and by testing with they vary in an intra-annual scale. Second, w

6. Self-organized dynamics in spatially structured populations.
Self-organization and pattern formation represent the emergence of order in temporal and spatial processes. Self-organization in population ecology is gaining attention due to the recent advances concerning temporal fluctuations in the population size of dispersal-linked subunits. We shall report that spatially structured models of population renewal promote

7. CHEMICALLY DEFINED, SYNTHETIC MEDIA FOR SPORULATION AND FOR GERMINATION AND GROWTH OF BACILLUS SUBTILIS
Donnellan, J. Edward, Jr. (U.S. Army Natick Laboratories, Natick, Mass.), Ella H. Nags, and Hillel S. Levinson. Chemically defined, synthetic media for sporulation and for germination and growth of Bacillus subtilis. J. Bacteriol. 87:332–336. 1964.—From 90 to 130 mg (dry weight) of spores (about 1% dark forms) were obtained (per liter) from a chemically
