Abstract The history of conifers introduced earlier elsewhere in the southern hemisphere suggests that recent invasions Argentina, Brazil, Chile and Uruguay are likely to increase number size. In South Africa, New Zealand Australia, early ornamental introductions small forestry plantations did not lead large‐scale invasions, while subsequent large were followed with a lag about 20–30 years by troublesome invasions. Large‐scale conifer plantation America began 50–80 later than Australia...
Abstract The impact of introduced herbivores on the composition and structure plant communities has been widely studied. However, little is known about how they affect wildlife. We studied feral horses under different grazing regimes birds in a nature reserve Pampas grasslands Argentina. areas that had predominantly tall grass (enclosures moderate intensity) showed greatest species richness total abundance birds. Some species, e.g. southern lapwing ( Vanellus chilensis ), were associated...
The advance of exotic tree and shrub species is one the main threats to conservation last relicts natural grassland in South America; however, control actions region are still scarce there almost no evaluations recovery ecosystems after removing invasive plants. Monitoring vegetation during years removal trees critical order decide whether an active restoration strategy necessary. montane four a dense invasion Aleppo pine ( Pinus halepensis ) described this study. Experimental clearing areas...
Luego de la elaboracion primera lista roja herpetofauna Republica Argentina,realizada en el ano 2000, son numerosos los cambios y estudios efectuados diferentesgrupos saurios Argentina. Si bien hay avances realizados todas las ramas labiologia relacionadas a lagartijas, progresos taxonomicos ecologicos mas evidentes.Debido estos progresos, implementacion sustanciales modificaciones conrespecto metodologia que se utilizara un grupo veintisiete especialistasde diferentes instituciones...
Parrots are among the most diverse and widely distributed groups of birds one threatened bird orders mainly due to habitat loss illegal poaching. Most parrots obligate cavity nesters, so logging mature trees transformation natural cliffs represent important threats their conservation. Here, we report novel observations Neotropical nesting in previously unrecorded substrates. We show first documented case cliff-nesting burrowing trying breed at ground level an abandoned owl cavity....
How birds adapt to urban life is a key question in evolutionary and conservation biology since urbanisation one of the major causes habitat loss worldwide. Some species are able deal with these anthropogenic changes but shortage nesting sites may preclude them from breeding cities. We conducted baseline survey cliff-nesting burrowing parrot Cyanoliseus patagonus around Bahía Blanca (Argentina), estimating minimum total 1,361 pairs at 24 (colonies) 2013. The showed facultative colonial...
Background and aims – Natural montane grasslands in the Southern Pampas of Argentina are expected to show a high potential for recovery after heavy grazing due their evolutionary history presence large herbivores productivity. The objective this work is compare plant diversity, bare soil percentage, biomass botanical composition between grazed non-grazed areas at different times following exclusion. Methods Vegetation was assessed on exclosures established 2006 nearby open by feral horses...
Argentina hosted pioneering classical weed biological control projects that were carried out by state institutions between the 1970s and 1990s, at a time when practice was almost unheard of in Latin America. Despite early development these initiatives, discipline did not prosper all discontinued. Notwithstanding, continued to provide agents for weeds many other parts world, ensuring expertise persisted. Although public concern about invasive plants chemical-dependent agricultural practices...
Plants with animal-dispersed fruits seem to overcome the barriers that limit their spread into new habitats more easily than other invasive plants and, at same time, they pose special difficulties for containment, control or eradication. The effects of animals on plant propagules can be very diverse, positive, neutral negative consequences germination and recruitment. Moreover, environmental conditions where seeds are deposited post-dispersal processes take place crucial fate. Prunus mahaleb...
Invasive alien species are the main agent of biodiversity loss in protected natural areas. Prevention is most appropriate management tool for addressing this challenge, however, virtually all ongoing efforts focused on established populations. Although invasion processes include stochastic components, it possible to compare different vectors introduction that operate a particular area terms their potential transport high risk efficiently and, once identified, establish strategies prevention,...
