An evaluation of methods for modelling distribution of Patagonian insects Una evaluación de los métodos para modelizar la distribución de insectos patagónicos

Revista Chilena de Historia Natural, 2009
Various studies have shown that model performance may vary depending on the species being modelled, the study área, or the number of sampled localities, and suggest that it is necessary to assess which model is better for a particular situation. Thus, in

Floristic variation in Sphagnum-dominated peatland communities of the Central Highlands, Victoria [PDF]

, 2013
The floristic composition of Sphagnum-dominated peatlands in the Central Highlands region of Victoria was surveyed (37º 25´ S; 145º 50´ E). NMDS ordination and cluster analysis divided the peatland sites into two broad groups with altitude being the most
