Relationship between climate and geographical variation of local woody species richness within the Mediterranean-type region of Chile RChHN
Becerra,Pablo I.
BACKGROUND: Latitudinal and altitudinal patterns of plant species richness have frequently been related to different climate variables such as precipitation, temperature and evapotranspiration. However, studies assessing this relationship have mostly compared different regions and used regional scales of richness (in quadrants of several km²). It is less known the relationship between climate and geographical patterns of species richness in local scales (richness in < 1 ha plots). For central Chile some studies have described geographical patterns of plant species richness, but only using regional scales to quantify richness. It is not known how local richness of plant species varies geographically and if climate variables are related to this variation....

Taxonomy and biology of a new Oecophoridae (Lepidoptera) from central Chile RChHN
HEATH-OGDEN,T.; PARRA,LUIS E..
The adult, larva, and pupa of Afdera jimenae Ogden &amp; Parra sp. nov. are described and illustrated. Larvae live in leaf litter throughout all instars and are generalists feeding upon the fallen leaves of a number of different plant species of sclerophyllous forests. Comments on morphological details and bionomics of this species are given. This is the second species of Afdera know for Chile

Soil respiration across a disturbance gradient in sclerophyllous ecosystems in Central Chile Ciencia e Investigación Agraria
Bown,Horacio E; Fuentes,Juan-Pablo; Perez-Quezada,Jorge F; Franck,Nicolás.
Sclerophyllous shrubs and forests are predominant in semiarid Central Chile and have a long history of degradation by fire, cultivation, firewood extraction and grazing. The aim of this study was to compare the amount and environmental drivers of soil respiration across a disturbance gradient in sclerophyllous ecosystems in the National Reserve Roblería del Cobre de Loncha in Central Chile. In a north-facing toe slope, four disturbance conditions were identified: slightly (D1) and moderately disturbed (D2) sclerophyllous forest, (D3) strongly disturbed thorn scrub and (D4) most disturbed A. caven savanna. Twelve 25×25-m plots (625 m²) were distributed equally across D1, D2, D3 and D4. Soil respiration (Rs), soil temperature (Ts), volumetric water content...
