A major problem in the strawberry production chain is the occurrence of fruit rot caused by fungi, thus, accurate identification of the pathogens associated with these rots is important for suitable management of diseases. During an assessment of postharvest diseases of strawberry plants, a rot caused by Calonectria was found. The surface of the infected fruits showed a slight leakage of liquid and the presence of mycelium with clearly defined hyphae containing a mass of conidiophores and conidia. Morphological examination was performed on isolates derived from single germinated conidium cultures, and phylogenetic analyses of four DNA loci (β-tubulin, histone H3, elongation factor and calmodulin) was undertaken. In order to confirm the pathogenicity, strawberry fruits and plants were dipped or sprayed with a conidial suspension. Strawberry fruits showed rot symptoms similar to those initially observed, and the plants developed leaf spot symptoms. The fungus was successfully reisolated from the infected tissues. Based on morphological and phylogenetic analysis, the fungus was shown to be distinct, and is described here as Calonectria fragariae sp. nov. This finding provides additional information for the better understanding of strawberry diseases in Brazil, enabling the development of more effective strategies of management of these diseases. |

The inselberg vegetation, in general, occurs in patches that vary in size, shape, number of plant species and are surrounded by a bare rock. The present study evaluated the species composition, structural analysis, and species-area relationships of vegetation patches on a neotropical inselberg in Rio de Janeiro state, southeastern Brazil. A total of 69 vascular plant species, from 31 families, were sampled in 84 vegetation patches varying in area from 0.02 to 500 m2, totaling 0.33 ha. Fabaceae and Cactaceae were the most representative families. Vellozia plicata and Selaginella sellowii presented the highest relative frequencies, relative dominances and importance values and were the most successful in the colonization of the studied rocky outcrop. A linear regression showed a positive correlation between patch size and species richness. Phanerophytes were the predominant life-form, with small patches being less rich in species and dominated by Selaginella mats. Our results suggest that the vegetation patches on the ?Morro do Itaoca? inselberg currently represent a refuge against fire and other anthropogenic disturbances for many typical species of the surrounding matrix. In addition, the locality is home to endemic and endangered species, which reinforces its importance for conservation actions.
A vegetação de inselbergs, em geral, ocorre em manchas que variam em tamanho, forma e número de espécies e são cercadas por uma matriz de rocha nua. O presente estudo avaliou a composição de espécies, estrutura e a relação espécie-área em um inselberg neotropical no Estado do Rio de Janeiro, sudeste do Brasil. Foram amostradas 69 espécies de plantas vasculares, de 31 famílias, em 84 manchas de vegetação com área variando de 0,02 a 500 m², totalizando 0,33 ha. Fabaceae e Bromeliaceae foram as famílias mais representativas. Vellozia plicata e Selaginella sellowii apresentaram as maiores frequências relativas, dominâncias relativas e valores de importância e foram as mais bem sucedidas na colonização do afloramento rochoso estudado. A regressão linear mostrou uma correlação positiva entre o tamanho da mancha e a riqueza de espécies, e fanerófito foi a forma de vida predominante, com pequenas manchas apresentando menor riqueza de espécies e dominadas pelos tapetes de Selaginella. Nossos resultados sugerem que os trechos de vegetação no inselberg Morro do Itaoca representam atualmente um refúgio contra incêndios e outros distúrbios antropogênicos para muitas espécies típicas da matriz circundante. Além disso, a localidade abriga espécies endêmicas e ameaçadas de extinção, o que reforça sua importância para as ações de conservação.
