Forest containing rata (Metrosideros umbellata) and kamahi (Weinmannia racemosa), with scattered trees of silver beech (Nothofagus menziesii), was sampled on Cedar Hill, Owaka Valley, Catlins Ecological Region. Diameter frequency distributions, age estimates, and basal area measurements show single cohort establishment of rata and kamahi, whereas three establishment phases of silver beech are e...

The diets of feral pigs and feral goats shot on the main Auckland Island in 1989 are described from analyses of stomach and rumen contents. Feral goats ate at least 50 species of plants, but only three, Metrosideros umbellata, Chionochloa antarctica, and Durvillea antarctica made up over 50% by dried weight of the food eaten. Feral pigs ate a mixed plant and animal diet, of which plants made up...

Miersiella umbellata (Miers) Urb. é uma espécie micoheterótrofa da família Burmanniaceae facilmente reconhecida por apresentar inflorescência umbeliforme e glândulas bilobadas na parte superior do ovário. Segundo a literatura científica, esta possui ocorrência confirmada Mata Atlântica brasileira em partes Amazônicas de outros países. Nesse trabalho, relatamos o primeiro registro M. Amazônia br...

Application of plant residues as soil amendment may represent a valuable recycling strategy that affects carbon (C) and nitrogen (N) cycling in soil–plant systems. The amount and rate of nutrient release from plant residues depend on their quality characteristics and biochemical composition. A laboratory incubation experiment was conducted for 120 days under controlled conditions (25 C and 58 %...

Nutrients are often released heterogeneously over time (e.g., in pulses) natural habitats. Different genotypes of the same plant species may vary their responses to temporal nutrient heterogeneity so that influence intraspecific interactions. To test effects on intra-genet (competition between ramets genotype) and inter-genet competition different genotypes), we conducted a greenhouse experimen...

Environments are ubiquitously heterogeneous in nature, and clonal plants commonly benefit from both integration foraging responses environments. While many studies have examined separately, few tested the effect of on response to environmental heterogeneity. We grew offspring ramets each three (Hydrocotyle vulgaris, Duchesnea indica, Glechoma longituba) homogeneous heterogenous soil environment...
