Abstract International agreements aim to conserve 17% of Earth's land area by 2020 but include no area‐based conservation targets within the working landscapes that support human needs through farming, ranching, and forestry. Through a review country‐level legislation, we found just 38% countries have minimum requirements for conserving native habitats landscapes. We argue increasing at least 20% landscape where it is below this minimum. Such target has benefits food security, nature's...
Abstract Increasingly, often ecologist collects data with nonlinear trends, heterogeneous variances, temporal correlation, and hierarchical structure. Nonlinear mixed‐effects models offer a flexible approach to such data, but the estimation interpretation of these present challenges, partly associated lack worked examples in ecological literature. We illustrate modeling using dynamics vegetation moisture field from northwestern Patagonia. This is Mediterranean‐type climate region where...
Abstract The expansion of homogeneous landscapes has been a major driver biodiversity loss, climate change and land degradation. There is an urgent need for transition to multifunctional that provide abundant nutritious food while also delivering several other contributions essential good quality life. However, implementing this process, especially in large‐scale agriculture without economic subsidies, remains unclear. We discuss guidelines based on science our experience as practitioners....
Forestry science has generated extensive knowledge about the operational aspects of forest harvesting machinery in industrial plantations. However, less is available for native forestry settings, particularly developing countries. To address this, astrip cutting field experiment, with chainsaw, was conducted to assess impact stand structure on productivity (m3/h) and fuel efficiency (m3/l) 12 contrasting plots secondary Nothofagus antarctica forests Northern Patagonia, Argentina....
Despite the growing recognition of sustainability in forest management, comprehensive multi-criteria evaluations silvicultural practices remain scarce, particularly Patagonia. In this study, we applied a decision analysis to evaluate different strip-cutting intensities secondary Nothofagus antarctica forests Northern Patagonia, Argentina. The performance four management alternatives was assessed: no cutting, low cutting intensity, medium and high intensity. These were evaluated across 11...
Abstract The forest–steppe ecotone in Argentine Patagonia has been planted with non-native Pinus ponderosa, Pseudotsuga menziesii, radiata, and P. contorta. As many other areas of the Southern Hemisphere, there is great concern about increasing landscape flammability. We determined, under lab conditions, live fuel moisture content (LFMC) leaf ignition these conifers, a naturalized poplar, 13 native species. mean LFMC was inversely related to conifer lower than that most natives, making...
Fire is one of the most important disturbances in terrestrial ecosystems and has major ecological socioeconomic impacts. regime describes variation individual fire events time space. Few studies have characterised grasslands spite importance these ecosystems. The aim this study was to describe recent (from 1973 2011) north-western Patagonian terms seasonality, frequency burned area. Our area covered 560 000 ha we used a remote sensing approach combined with statistics obtained from...
Unmanned aerial vehicles (UAVs) have gained attention for forestry applications in recent years. These technologies provide ultrahigh-resolution spatial data detailed mapping of forest structure, among other applications. UAVs mainly been tested high-value timber stands, but little is known about their performance woody ecosystems such as shrublands that also key ecosystem services. Field measurements are time-consuming, so could be used instead to shrubland management and conservation. We...
Fire severity influences the recovery and biodiversity of plant communities. We compared early post-fire functional groups in two sites (one burnt with high one low severity) north-western Patagonian steppe. sampled soil seed banks, as well composition cover aboveground species, calculated richness, diversity percentage exotic species. Low fire increased vegetation whereas reduced all groups, exception fugitive Tiller production perennial grasses decreased due to bud bank mortality. In bank,...
Professionals of the social and environmental sciences must solve problems (answer questions) based on data sampling analyses. Commonly, all professionals face similar challenges: they need to take decisions a population (e.g., trees region), but only have from sample (some that region). A key tool in this process is propose models for response variable (tree growth as function tree age climatic conditions) then use model predictions when cut according conditions). In paper we discuss how...
Several countries have carried out surveys of managed honeybee colonies, the results which suggest high loss rates all over world. Although Latin America is an important apicultural region, estimates colony losses are lacking. This study quantified in Argentina during 2015-16 season. Overall, survey included 28,204 15.5% were recorded as lost. The total winter (13.0%) higher than summer (3.9%), a result that contrasts with collected Uruguay where no seasonality was observed 2013-14 losses....
Una estrategia de manejo forestal que podría combinar exitosamente la producción y conservación biodiversidad en bosques naturales, es su enriquecimiento con árboles nativos valor maderero. En ciertos Patagonia (e.g. matorrales) esto requiere definir el grado apertura inicial del dosel para garantizar éxito plantación. este trabajo, evaluamos efecto intensidad (IA) supervivencia crecimiento altura plantaciones especies forestales nativas maderables, tres sitios contrastantes (ladera sur: LS,...
Abstract Background Forest management has historically focused on provisioning of goods (e.g. timber, biomass), but there is an increasing interest to manage forests also maintain biodiversity and provide other ecosystem services (ES). Methods We evaluated the effects firewood harvesting intensity different ES in three contrasting shrubland sites northern Patagonia (Argentina). At each site, four treatments, representing various levels harvest intensity, were randomly assigned eight...
Abstract. Fire is a critical disturbance in the structuring and functioning of most Mediterranean ecosystems. In northwestern Patagonia, vegetation patterns are strongly influenced by fire environmental heterogeneity. Dendroecology, together with satellite imagery GIS, have been demonstrated to be useful tools studies that relate effects patches, species dynamics at landscape scale. Such can approached from ecology, which has evolved last years supported development remote sensing GIS...
Although shrublands can be highly abundant, their bioenergy potential has barely been addressed. This is the case in northern Patagonian shrublands, where there a lack of knowledge regarding biomass quantity and quality. The objective this study was to develop equations for young shoots (resprouts) five main woody species growing shrublands; quantify energy properties woods and, ultimately, estimate stocks resprouts three contrasting shrublands. Resprouts were harvested field, size (diameter...
Nothofagus antarctica (G. Forst.) Oerst. stands of northern Patagonia (Argentina) have great potential to provide multiple ecosystem services. Nonetheless, the lack basic information limits application silvicultural treatments this forest type. This study reports early response three systematic strip thinning (30%, 50%, and 70%) carried out during 2013 in a 30-year-old N. stand, where control plots (i.e., no thinning) were also established. Subplots located within each plot. Basal diameters...
