Effects of intensive human management on the taxonomic and functional diversity of ground beetles in a planted forest landscape

Autor: Pamela Krug, Analía Soledad Nanni, Ruben Dario Quintana, Armando Conrado Cicchino

Publikováno v: Biodiversity and Conservation. 30:3717-3735

The rapid expansion of planted forests harms native biodiversity. Few studies report the effects of replacing wetlands with planted forests on ground beetles. We analyze how the taxonomic and functional diversity of ground beetles are affected by int

Wetland Bird Response to Habitat Composition and Configuration at Multiple Spatial Scales

Autor: Noelia C. Calamari, Gregorio I. Gavier-Pizarro, Yanina Vanesa Sica, Ruben Dario Quintana, Jaime N. Bernardos

Publikováno v: Wetlands. 40:2513-2525

Wetlands loss has major consequences for biodiversity. The Delta of Parana River is one of the largest wetland ecosystems in South America undergoing rapid conversion of freshwater marshes to pastures. We evaluated the response of nine wetland bird s

Context: Modifications in natural landcover generally result in a loss of habitat availability for wildlife and it’s persistence will depend largely on their spatial configuration and functional connections. Argenteohyla siemersi is a threatened an

Ground Beetles in a Changing World: Communities in a Modified Wetland Landscape

Autor: Andrea Laura Magnano, Armando Conrado Cicchino, Ruben Dario Quintana, Analía Soledad Nanni, Natalia Fracassi

Publikováno v: Neotropical Entomology. 48:729-738

Wetlands are being increasingly affected by anthropogenic activities worldwide. The Lower Delta of the Paraná River, one of the most important wetlands in Argentina, has been profoundly altered because most of the natural environments were drained o

Population genetics of the capybara, Hydrochoerus hydrochaeris, in the Chaco-pampean region

Autor: María Luisa Bolkovic, Soledad Byrne, Ruben Dario Quintana, Juan Ignacio Tunez

Publikováno v: Mammalian Biology. 96:14-22

Hydrochoerus hydrochaeris is an herbivorous rodent that inhabits most wetlands of South America. It is a well-known species, but studies about their population genetics are scarce. The aim of this study was to analyze the genetic diversity, populatio

Changes in bird assemblages in an afforestation landscape in the Lower Delta of the Paraná River, Argentina

Autor: Analía Soledad Nanni, Andrea Laura Magnano, Ruben Dario Quintana, Natalia Fracassi

Publikováno v: Emu - Austral Ornithology. 119:346-354

Global loss of wetlands has increased significantly in recent years. As a result, many wetlands have experienced changes in biotic communities, including birds. We compare the temporal vari...

Distribution and richness of amphibians under different climate change scenarios in a subtropical region of South America

Autor: Valeria Bauni, Facundo Schivo, Pamela Krug, Ruben Dario Quintana

Publikováno v: Applied Geography. 103:70-89

Amphibians are a valuable indicator group to study potential impacts of climate change (CC) because reproduction is closely linked to the availability of freshwater. Climate projections for the humid subtropical region of South America predict an inc

Effects of livestock exclusion on density, survival and biomass of the perennial sagebrush grass Hymenachne pernambucense (Poaceae) from a temperate fluvial wetland

Autor: Ruben Dario Quintana, Andrea Laura Magnano, Elizabeth Nora Astrada, Ricardo Vicari, Pamela Krug, Analía Soledad Nanni

Publikováno v: Acta Oecologica. 86:72-78

In Argentina, the intensification of soybean production has displaced a substantial proportion of cattle ranching to fluvial wetlands such as those in the Delta of the Paraná River. Cattle grazing affects structure and dynamics of native forage plan

Non-monotonic vegetation activity trends in the Lower Delta of the Paraná River: Masking evidence of wetland degradation?

Autor: Ruben Dario Quintana, Gregorio Gavier-Pizarro, Yanina Vanesa Sica, Diego Sebastián Aquino

Publikováno v: Remote Sensing Applications: Society and Environment. 24:100626

To understand the consequences of unsustainable management practices and global change, analyzing the patterns of ecosystem functioning and land degradation is as important as quantifying the spatio-temporal patterns of land cover loss. This is parti
