Tree monocultures in a biodiversity hotspot : impact of pine plantations on mammal and bird assemblages in the Atlantic Forest
(Elsevier, 2018-09-01)Forest plantations of fast-growing exotic species constitute an important economic activity in tropical and temperate regions of developing countries. Large areas of native forests and grasslands are being turned into tree ... -
Productividad de un harvester en raleos de plantaciones de pinos en el noreste argentino
(Universidade Federal de Santa María, 2018-10-01)Se analizó la productividad de segundos y terceros raleos en plantaciones de Pinus taeda y Pinus elliottii var. elliottii x Pinus caribaea var. hondurensis realizados con harvesters de ruedas en el Noreste Argentino. Los ... -
Recuperación de valor con harvester aplicando tecnología de optimización de trozado
(Instituto de Pesquisas e Estudos Florestais, 2019-06-01)La optimización de trozado a bordo de harvesters es una tecnología que posibilita incrementar el valor de la madera cosechada. En este estudio se analizó el potencial de optimización del valor de los árboles cosechados y ... -
Edge effects on dung beetle assemblages in an Andean mosaic of forest and coffee plantations
(Wiley Blackwell Publishing, 2016-11-01)In landscapes dominated by agriculture, conspicuous edges often occur between landscape elements. However, there is disagreement about the existence and intensity of edge effects, and information about species‐specific ... -
Styrax Acuminatus (Styracaceae), nuevo registro para la flora Argentina
(Darwiniana Nueva Serie, 2019-07-31)El género Styrax incluye cerca de 130 especies leñosas. Para la Argentina han sido registradas dos especies. En la presente contribución una tercera especie, Styrax acuminatus, es citada por primera vez para la provincia ... -
Ocurrencia de Topea Patens y de la Subtribu Topeinae (Apocynaceae: Asclepiadoideae) en Brasil
(Instituto de Botánica del Nordeste, 2018-11-01)La especie Topea patens (Apocynaceae) se menciona por primera vez para el Brasil, en el estado de Mato Grosso de Sul, lo que a su vez representa el primer registro para el país de la recientemente fundada subtribu Topeinae. ... -
Voyria Aphylla (Gentianaceae), la primera Eudicotiledónea Micoheterótrofa registrada para la flora Argentina
(Instituto de Botánica del Nordeste, 2019-06-15)Sobre la base de dos muestras recolectadas en Misiones, se documenta por primera vez para el territorio argentino la presencia de una especie micoheterótrofa aclorofilada Voyria aphylla (Jacq.) Pers. (Gentianaceae). La ... -
Efecto de la densidad de las forestaciones y la intensidad de cosecha en raleos mecanizados con harvester
(Instituto de Pesquisas e Estudos Florestais, 2019-09-01)El objetivo de este estudio fue evaluar cómo la densidad de la forestación y la intensidad de los raleos afectan a la cosecha con harvester. Fueron evaluados siete harvesters diferentes, en nueve situaciones de segundo ... -
Cats under cover : habitat models indicate a high dependency on woodlands by Atlantic Forest felids
(Wiley Blackwell Publishing, 2019-03-01)Four Neotropical small and medium felids—the ocelot, jaguarundi, margay, and southern tiger cat—have overlapping geographic distributions in the endangered Atlantic Forest. Local studies show that these felids avoid areas ... -
Neotropical xenarthrans : a dataset of occurrence of xenarthran species in the neotropics
(Ecological Society of America, 2019-07-01)Xenarthrans -anteaters, sloths, and armadillos- have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and ... -

Relationship between land uses and diversity of dung beetles (Coleoptera: Scarabaeinae) in the southern Atlantic forest of Argentina: which are the key factors?
(Springer International Publishing Switzerland, 2018-07-26)The loss of natural habitats is one of the main drivers of biodiversity decline. Anthropogenic land uses preserving biotic and abiotic conditions of the native ecosystem are more suitable to preserve the native biodiversity. ... -
Tree retention in cattle ranching systems partially preserves dung beetle diversity and functional groups in the semideciduous Atlantic forest : The role of microclimate and soil conditions
(Elsevier, 2018-10-01)The disturbance of natural environments affects, among others, the diversity of dung beetle assemblages, which could have serious consequences for the ecological processes regulated by these insects. The objective of this ... -
Influence of land use on the trophic niche overlap of dung beetles in the semideciduous Atlantic forest of Argentina
(John Wiley & Sons, 2018-11-01)The degradation and replacement of natural ecosystems affect species abundance, diversity and interspecific interaction through the modification of resource availability and environmental conditions. Land uses preserving ... -
Influence of land use on the taxonomic and functional diversity of dung beetles (Coleoptera: Scarabaeinae) in the southern Atlantic forest of Argentina
(Springer International Publishing Switzerland, 2008-03-01)The degradation and replacement of native ecosystems affects both their taxonomic and functional biodiversity. However, native species may find a gradient of habitat suitability in different land uses within a region. The ... -
