(Elsevier, 2013-08-15)Development of appropriate forest conservation and management measures for a given tree species includes the identification of distinct genetically homogeneous units across its overall distribution range, which depends on ... -
Management of Sirex noctilio populations in exotic pine plantations: critical issues explaining invasion success and damage levels in South America
(Springer Nature, 2018-11)Plantation forestry with non-native trees is steadily increasing in the southern hemisphere and alien pest problems are also accumulating, as a consequence of the growing international movement of people and goods. Here, ... -
Managing nuisance social insects in urban environments : an overview
(2017-04)Urbanization is progressing worldwide where social insects often attain pest status. We present an overview of the practices applied for the management of social insects in urban settings from 1990 to 2016. We found that ... -
Managing Socio‐Ecological Systems to Achieve Sustainability: A Study of Resilience and Robustness
(Wiley, 2013-02)Growing symptoms of the mismanagement of socio‐ecological systems (SESs) show that the long‐term existence of these systems is threatened. SES management improvement is the aim of many policy measures. But how successful ... -
Manejo nutricional pre y post-destete en crias de cabras angora del norte de la patagonia
(Facultad de Ciencias Veterinarias, Universidad Nacional de La Pampa, 2021-12)En los hatos de cabras Angora en el norte de la región Patagónica, las crías suelen manifestar deficiencias nutricionales desde el nacimiento hasta el destete a los 90 días que se asocian a bajas tasas de señalada y destete, ... -
Maqui (Aristotelia chilensis [Mol.] Stuntz) morphological and phenolic traits associated with forests type and latitudinal gradient in natural populations of Patagonia Argentina
(Elsevier, 2021-12)Maqui (Aristotelia chilensis [Mol.] Stuntz) is a native berry of the Patagonia Andean forests, which has one of the highest antioxidant levels currently known. This biochemical characteristic strongly depends on the phenolic ... -
Mate-searching behavior in the invasive German wasp, Vespula germanica, in Patagonia
(John Wiley & Sons Ltd, 2018-07)In order to increase the probability of reproduction, social insects can adopt various mate‐finding strategies, such as increasing densities of males at specific locations, and/or visual and chemical cues that attract the ... -
Melatonin in Arabidopsis thaliana acts as plant growth regulator at low concentrations and preserves seed viability at high concentrations
(2015-09)Since the discovery of melatonin in plants, several roles have been described for different species, organs, and developmental stages. Arabidopsis thaliana, being a model plant species, is adequate to contribute to the ... -
El Mes de la Entomología: acercando el laboratorio de investigación científca a las escuelas de nivel inicial de la Patagonia = Entomology Month: Bringing Scientifc Research Closer to Elementary Schools in Patagonia
(Asociación de Docentes de Ciencias Biológicas, 2015)Como investigadores en ciencias, entendemos que enseñar las ciencias naturales en la escuela primaria es un desafío para los docentes y una excelente oportunidad para sentar las bases del pensamiento científico. “El Mes ... -
Mixed Nothofagus forest management: a crucial link between regeneration, site and microsite conditions
(Springer Nature, 2020)Canopy openings due to harvesting practices constitute a disturbance that changes the environmental conditions of microsites. Its impact on the relative performance of the regeneration of different tree species could also ... -
Modeling leaf maximum net photosynthetic rate of Festuca pallescens, the dominant perennial grass of Patagonian pine-based silvopastoral systems
(2011-09)The integrated relationship in a simple mechanistic model between the critical environmental factors controlling leaf photosynthesis of understory species would be a useful tool to optimize the management of the silvopastoral ... -
Modeling of the annual cycle of Melophagus Ovinus (L.) in two sheeps flocks of Patagonia, Argentina
(2018-03)The ked Melophagus ovinus (L.), one of the most common obligate external parasites in sheep, is a recurrent problem in temperate sheep production areas worldwide. Modeling of its annual dynamics, which is lacking, can ... -
Modelling the distribution of forest pest natural enemies across invaded areas: Towards understanding the influence of climate on parasitoid establishment success
(Elsevier, 2019-05)Classical biological control is a pest management practice frequently deployed against invasive insects. However, introduced natural enemies too often fail to establish, and this has been partly explained by climatic ... -
Modelo de estados y transiciones de los ñirantales del NO de la Patagonia como herramienta para el uso silvopastoril sustentable
(Asociación Argentina de Ecología, 2017-08)Desarrollamos un modelo de estados y transiciones (MEyT) para el bosque de ñire (Nothofagus antarctica) en el norte de la Patagonia, con el fin de sintetizar el conocimiento disperso sobre las repuestas de este sistema al ... -
Molecular bases of responses to abiotic stress in trees
(Oxford University Press, 2020-06)Trees are constantly exposed to climate fluctuations, which vary with both time and geographic location. Environmental changes that are outside of the physiological favorable range usually negatively affect plant performance ... -
Molecular characterization of Brucella ovis in Argentina
(Elsevier, 2020-06)Brucellosis in rams is caused by Brucella ovis or Brucella melitensis and it is considered one of the most important infectious diseases of males in sheep-raising countries. Molecular characterization of Brucella spp. ... -
Morpho-physiological responses of Nothofagus obliqua to light intensity and water status, with focus on primary growth dynamics
