In arid environments, direct facilitation (microhabitat amelioration) and indirect facilitation (“associational resistance” via protection from herbivory) among plants of different species may act simultaneously. Little is known about their relative effects. One way to disentangle the effects is by evaluating spatial associations. We examined the r...
Successful persistence of dry forests depends on tree regeneration, which depends on a balance of complex biotic interactions. In particular, the relative importance and interactive effects of shrubs and herbivores on tree regeneration are unclear. In a manipulative study, we investigated if thornless shrubs have a direct net effect, an indirect po...
La ganadería extensiva en bosques como el Chaco seco, es un importante uso de la tierra prac-ticado por comunidades locales. Esta actividad ha sido estudiada en décadas pasadas y recien-temente, siendo necesario resumir lo conocido hasta la fecha. Aquí, sintetizamos nuestra evi-dencia sobre la relación ganadería-regeneración y experiencias de resta...
Livestock grazing can be a problem for forest conservation because it can generate heterogeneous and unpredictable changes in plant communities. Understanding these changes is important for generating management strategies that are compatible with long-term conservation of threatened forests. Livestock exclusion is a useful experimental approach us...
Extensive livestock ranching is one of the main drivers of habitat degradation in terrestrial communities in the dry Chaco forest (Argentina). Grazing intensity could differentially affect native mammals and their interactions, which could impact both, native mammal communities and livestock production systems. Here, we determined how the activity...
Knowing what native trees can recruit on degraded areas allows selecting the best species to restore these sites. However, as this information is not often available, experimentation is required before large-scale planting. This study used ex situ experiments to make these decisions on recruitment. Competition with r-strategist plants, excessive so...
Jaguar (Panthera onca) populations are declining in Bolivia because of human activity. Understanding the attitudes and perceptions of local people toward threatened species and the factors that can influence them is crucial for their protection. This study evaluated how local people’s knowledge, attitudes, and perceptions towards jaguars in souther...
El efecto del pastoreo por ganado en las comunidades vegetales es un tópico que ha sido estudiado en diversos ecosistemas del mundo. El bosque seco del Gran Chaco (comúnmente llamado bosque chaqueño) es el segundo bosque más importante de Sudamérica después del Amazonas y uno de los puntos críticos de conservación a escala continental, pero se encu...
Disparity between the knowledge produced and knowledge required to address complex environmental challenges, such as biodiversity conservation and climate adaptation, continues to grow. Systems thinking under the Open Standards for Conservation framework can help close this gap by facilitating interdisciplinary engagement, advancing
conversations o...
Throughout its range in Latin America, the jaguar Panthera onca is threatened by habitat loss and fragmentation, and by conflict as a result of coexistence with people. This Near Threatened species is a top predator, and is often illegally hunted. Understanding people's attitudes and perceptions and the factors that could influence them is crucial...
La ganadería extensiva (actividad económica más difundida en pobladores rurales del Chaco semiárido) genera en algunos casos áreas sobrepasto- readas. Una estrategia de restauración consiste en introducir suelo superfi- cial de zonas no degradadas, que contiene propágulos de distintas formas de vida, nutrientes y microorganismos necesarios para el...
Los incendios forestales en bosques montañosos pueden modi car las tasas de in ltración y de escorrentía, lo cual aumenta el arrastre de sedimentos ladera abajo. Por lo tanto, es urgente diseñar e implementar técnicas de control de sedimentos en laderas incendiadas. Una metodología sencilla y económica es la construcción de fajinas (i.e., una empal...
Wildfires in mountain forests can trigger changes in rates of infiltration and runoff, increasing sediment flow downhill. Therefore, it is urgent to design and implement soil erosion control techniques on burned slopes. A simple and economic method is the construction of “fajinas” (cylindrical palisade built with braided branches). Our objective wa...
In semiarid regions, livestock is concentrated around water sources generating a piosphere pattern (gradients of woody vegetation degradation with increasing proximity to water). Close to the water source, livestock may affect the composition, structure and regeneration strategies of woody vegetation. We used the proximity from a water source as a...
Los incendios forestales podrían aumentar la susceptibilidad del suelo a la erosión hídrica, afectando importantes servicios ambientales. Esto cobra especial interés en paisajes de montaña cercanos a centros urbanos. Por lo tanto, estudiamos cómo varía la tasa de escorrentía y de erosión de suelos en respuesta a la ocurrencia de incendios forestale...
Wildfires could enhance soil susceptibility to water erosion, affecting important environmental services, especially in mountain landscapes near urban centers. For this reason, we study runoff and soil erosion in response to occurrence of wildfires, intensity of simulated rain, slope and soil moisture, in a mountain landscape covered by subtropical...

The production of cochineal is not widespread in Argentina but has a potential for high quality carminic acid. The object of this work was to determine the acid content of cochineal carmine raised at three different heights. 100 two-yearold, uniform prickly pear cladodes were used, at three different levels (1.50, 1.00 and 0.50 m). Each cladode was...
The tender cladodes of prickly pear cactus (Opuntia ficus-indica (L.) Mill.) commonly called nopalitos are widely consumed in Mexico, whereas in Argentina they are scantily used vegetables. The aim of the present work was to evaluate the effects of the application of three organic manures (hen, cow and sheep) to the production of young cladodes (no...
Logging activities generate microsites that can be colonized by different woody plant species whose regeneration may be influenced by biotic and abiotic factors. This work describes three microsites created by logging (main roads, skid trails and logging gaps) in two sites with different recovery time (one and two years) in the semi-arid Chaco of A...
Para manejar y conservar una población biológica es necesario conocer las etapas de su ciclo de vida. El quebracho blanco es una especie clave en el ecosistema chaqueño y es necesario emprender estudios relacionados con su producción de semillas. Se estudió el número de semillas fértiles (con embrión) y vanas por fruto (sin embrión) y la relación e...

Of the world’s six flamingo species, the rarest and least known are the James’ Flamingo and the
Andean Flamingo. These species inhabit only the lakes in the puna and high Andes of
Argentina, Bolivia, Chile and Peru. To update information on global distribution and abundance
of both species, we conducted a fifth simultaneous census during summer 200...
We studied the composition and structure of the woody plant community in a logged/grazed forest, an abandoned road, a burned forest, and a primary forest as a control. The disturbances occurred 10 years prior to the study. The logged/grazed forest was similar in physiognomy to the primary forest, whereas shrubs dominated the abandoned road and burn...
We measured waterbird richness and abundance, and characterized wetland features (altitude, size, and presence of submergent vegetation) of 50 altiplano wetlands, during summer and winter, 1998. We estimated 36,700 individuals of 24 avian species during the summer census. James' Flamingo (Phoenicoparrus jamesi) and Andean Flamingo (P. andinus) were...

I have exclosures (9 years and 2 years) in a dry forest and I found lower soil bulk density and higher C, N and OM contents outside the exclosures, in relation to the excluded areas.
I fitted a mixed model with lme function in R (2 categorical factors, 2 quantitative factors, and blocks). One of the quantitative factor was statistically significative, as well as other factors. How can I plot the linear estimated relationship between the response variable and one of the quantitative factor?

Comprender la relación entre los patrones de diversidad taxonómica de plantas del sotobosque y la ganadería en el bosque chaqueño semiárido a distintas escalas (desde una escala de sitio a jerarquías menores).
Los ambientes semiáridos (bosques secos, monte, etc) representan la mayor proporción de ambientes naturales del NOA, y se caracterizan por presentar diferentes grados de degradación debido a perturbaciones como la ganadería, extracción de leña e incendios. Los ambientes perturbados se regeneral naturalmente en mayor o menor medida, y es posible acelerar dicha recuperación utilizando técnicas de restauración. Para que dichas técnicas sean exitosas, deberían basarse en mecanismos ecológicos probados empíricamente. En este proyecto, evaluaremos distintas técnicas de restauración ecológica para promover la recuperación de sitios afectados por del ganado doméstico en el bosque chaqueño semiárido. Además, investigaremos los requerimientos germinativos de arbustos potencialmente nodriza, para realizar en el futuro acciones de reforestación en sitios sobrepastoreados.
