No que se refere à biodiversidade fúngica do Paraná, o estado é considerado entre os mais estudados, onde mais de 1.700 espécies são conhecidas, no entanto não há relatos da micota da região sudoeste do estado. Este trabalho teve como objetivo, coletar e identificar a biodiversidade de fungos macroscópicos em um fragmento de floresta ombrófila mista. As coletas foram realizadas mensalmente, de agosto de 2009 a outubro de 2010, abrangendo todos os períodos climáticos. Os basidiomas foram coletados ao longo da área, abrangendo platô, vertente e baixio. O procedimento de coleta foi realizado seguindo a metodologia adotada por Souza (1980). Após a coleta, os fungos foram fotografados, coletados com auxílio de canivetes, depositados em sacos individuais de papel ou recipientes plásticos, sendo identificados quanto ao habitat e o substrato. Foram encontrados dezenove gêneros pertencentes a treze famílias de Ganodermataceae,
This study characterized the demography and spatial pattern of a yerba mate (Ilex paraguariensis A.St.-Hil) population covering areas with different use histories (Presence and Absence of Cattle) in a Araucaria Forest. Data collection was performed in three ha, half in each area. The frequency of individuals by height, spatial distribution pattern, diameter distribution (for reproductive individuals) and sexual ratio were evaluated. An inverted “J” pattern predominated, being exclusive to an area with Cattle Presence, a place which presented a lower density of individuals. The predominant spatial distribution pattern was aggregated, and the reproductive individuals have a preferentially random pattern at the shortest distances. Results indicated that cattle presence changes the density of I. paraguariensis individuals and the proportion of individuals in the evaluated demographic classes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
