The Impact

Abstract Information on how wildlife is affected by pine plantation clearcutting is relevant for designing management strategies to promote biodiversity conservation in productive systems. By comparing the number of records of carnivores in a mosaic of pine plantations and native forest remnants before and after pine harvesting, we assessed the effect of plantation clearcutting on carnivore presence in ten sampling areas in Central Chile. We also included a number of covariates to account for their potential confounding effects, for example, the distance between each site and the nearesting human settlement and vegetation cover. A total of 10 species were observed, but no negative effect of clearcutting on carnivore presence was detected. Only the culpeo fox (Lycalopex culpaeus) responded positively to the harvesting of pine plantations. The threatened kodkod (Leopardus guigna) was absent in clearcut areas and the number of records increased in forests or plantations with a dense understorey. The domestic dog (Canis lupus familiaris) responded positively to human settlements and seems to prefer more open areas. The number of records for the Puma (Puma concolor) and the domestic cat (Felis silvestris catus) was too few, and hence, we could not make any inference regarding these two species. The other species recorded showed different responses to one or more of the included covariates. Although our results showed that the recording of some species could change in the short term after pine harvesting, future studies should assess the impact of clearcutting at a much higher scale, both in terms of space and time.

Coarsely crystalline residual blueschist boulders from the Coastal Range of south-central Chile (41°S) contain relict eclogite–amphibolite assemblages that provide evidence of pre-Carboniferous high pressure relative to temperature (high P/T) metamorphism along the southwestern continental margin of Gondwana. Early assemblages in the exotic boulders include omphacite, garnet, and hornblende that indicate eclogite-facies conditions of T = 553 ± 30 °C and P > 1.32 ± 0.04 GPa during metamorphism, corresponding to a low geothermal gradient of <12.5 °C/km. These phases are replaced to varying degrees by sodic amphibole + epidote assemblages. Relict hornblende from an early garnet amphibolite assemblage within blueschist yields an 40Ar–39Ar plateau age of 361 ± 1.7 Ma, providing a minimum age for early high P/T metamorphism. Coarse white micas that partially replace the hornblende and are in textural equilibrium with glaucophane yield plateau and near-plateau ages of 325 ± 1.1 Ma and ∼320 Ma, respectively. We interpret these data to indicate that late Paleozoic high P/T metamorphism related to subduction of oceanic lithosphere along the southwestern paleo-Pacific margin of Gondwana began prior to 361 Ma (Late Devonian). Subsequent retrograde metamorphism involving fluid infiltration and decreasing thermal gradients resulted in conversion of coarse eclogite–amphibolite to blueschist by ∼325 Ma in the dated samples.
