Temporal and structural analysis of the relationships between orthoptera and vegetation.

The authors carry out a study on a grasshopper community in a protected zone of the Limousin region. The relationship between the floristic composition of the stations and the grasshopper composition is evaluated over three months (July, August and September) with NMDS analysis and Mantel's test. Correlations (Spearman rho) between vegetation factors (height, diversity, compacity and relative humidity) and the density of Orthoptera are also studied. Orthopteran community is more closely adjusted to floristic composition in August and September than in July. Density and diversity of Orthoptera are linked to vegetation compacity and diversity, and specially to the group Gramineae, Cyperaceae and Joncaceae. Results are commented according to the literature.
