Article
Full-text available
In the last decades, pollinators have drastically declined as a consequence of anthropogenic activities that have local and global impacts. The food industry has been expanding intensive agriculture crops, many of them dependent on animal pollination, but simultaneously reducing native pollinator habitats. Chile is a good example of this situation....

Full-text available
Invasive species are one of the main biodiversity loss drivers. Some species can establish and thrive in novel habitats, impacting local communities, as is the case of managed pollinators. In this regard, an invasive species' expansion process over time is critical for its control and management. A good example is the European bumblebee Bombus terr...

The order Diptera is the second most important group of pollinators worldwide. Many flies are considered generalist pollinators, but specialist flower flies' associations are rare or uncommon. The present study aimed to determine the level of specialization in pollination for Aneriophora aureorufa (Philippi, 1865) (Diptera: Syrphidae), an endemic s...

The order Diptera is the second most important group of pollinators worldwide. Many flies are considered generalist pollinators, but specialist flower flies’ associations are rare or uncommon. The present study aimed to determine the level of specialization in pollination for Aneriophora aureorufa (Philippi, 1865) (Diptera: Syrphidae), an endemic s...
Article
Certified organic agriculture stipulates a set of principles and standards which run farmer practices. The current global demand for organic food has raised new challenges for organic agriculture, which can be difficult to address when management is subject to the forces of conventionalisation. Using production of highbush blueberry (Vaccinium cory...

We estimate habitat loss and fragmentation in a hoverfly, Aneriophora aureorufa, used as a representative forest specialist species. This species is a pollinator specialist of two native trees, forming a triad endemic to the South American Temperate Rainforest (SATR). We combine Species Distribution Models with species-specific requirements to esti...
Article
Full-text available
The global pollination crisis is not only produced by loss of pollinators but also by their homogenization, both processes caused by humans. This crisis impacts the persistence of many native plants species worldwide. In this document we analyze the ecological impacts that warrant the prohibition of new income of commercial bumblebee, Bombus terres...

1. The global trade of species promotes diverse human activities but also facilitates the introduction of potentially invasive species into new environments. As species ignore national boundaries, unilateral national decisions concerning species trade set the stage for transnational species invasion with significant conservation, economic and polit...
Article
Full-text available
The notion of cultural landscape was deployed to analyze transformation processes of rural landscapes. As a case study, environmental degradation processes in La Araucania (Chile) region were analyzed. The goals of actions over the territory and their driving forces were determined. These actions were related to economic motives external to local i...

In Chile, as in many other parts of the world, agroecology was first developed from studies on traditional agricultural systems. In the late1970s and early 1980s, when a large portion of Chilean population was under high poverty, the first notions for agroecological thinking arised. In the early 1980s, NGOs were the first entities to do applied agr...
Article
In this study pollinators visiting highbush blueberry fields set in landscapes with differing land use pattern in south-central Chile were investigated. Effects of spatial buffers from 0.5 to 8 km around each blueberry field on the abundance of the main wild pollinator, Bombus terrestris queens, were tested. Wild B. terrestris abundances were posit...

Este trabajo pretende fomentar el entendimiento de la interrelacion entre riesgos ambientales generados por el cambio climatico y la capacidad de utilizar unidades y sistemas agricolas (como sistemas socioecologicos) para resistir a estas perturbaciones y persistir en el tiempo. Fueron evaluadas 177 familias que practicaban agricultura campesina de...
Article
Full-text available
The selection of good planting sites is critical for the success of blueberry plantations. The objective of the present study was to identify farm territorial units suitable for the establishment and management of highbush blueberry crops on a farm in southern Chile. A farm-level characterization was developed, and districts and sites were classifi...

A study was conducted to determine the effect of synthetic mulch on the diversity and abundance of carabid beetles in an organic blueberry crop. The treatments consisted of plastic mulch, plastic mulch combined with pine needles, pine needles only and bare soil as control. Beetles were captured using pitfall traps. The number of individuals collect...

Gastó, J., L. Vera, L. Vieli, and R. Montalba. 2009. Sustainable Agriculture: Unifying Concepts. Cien. Inv. Agr. 36(1): 5-26. This work is the product of a long process that tried to approximate the principia involved in sustainable agriculture in an attempt to analyze it. We believe that these principia are crucial for the systematic, rigorous, an...

We investigated the remaining puma habitat of south ern San Francisco Bay Area, CA. First, we created habitat suitability maps of the area for pu mas, which integrated principle prey presence (mule deer) as well as a condition index to account for roads, development and population density. Then using Zonation software, we identifie d core areas of...

En esta propuesta se pretende desarrollar, y aplicar en el análisis del proceso de compra de tierras de CONADI, un modelo teórico-metodológico complementario, diseñado desde una perspectiva compleja, que permita dar cuenta de los efectos e impactos reales y significativos de la política, programa u otros procesos con connotación sociocultural y ambiental. Con esta finalidad, se asume como marco general la perspectiva de “Sistemas Socioecológicos”, agroecología y calidad de vida humana
