Revisión del Inventario de Aves de la Provincia de Santa Fe, Argentina

Spatial Variation in Bird Assemblages are Linked to Environmental Heterogeneity in Agricultural Landscapes in the Province of Entre Ríos, Argentina

“…Species were classified according to residency status following Fandiño and Giraudo (2010): resident (R); southern migrants from the north (SMN); and southern migrants from the south (SMS). The categories of longitudinal migrants from the east (LME) and longitudinal migrants from the west (LMW) were not included as none of the species detected corresponded to these categories.…”

Araneofauna (Arachnida: Araneae) de suelo en bosques nativos, exóticos y pajonales del Parque General San Martín, Entre Ríos Argentina

“…Posiblemente, para mejorar y acrecentar el inventario de especies en los ambientes del parque se deberían incorporar otras técnicas de colecta, en otros períodos y estratos respecto a futuras investigaciones. En términos de conservación, es fundamental completar los inventarios parciales existentes para evaluar la biodiversidad y sus problemas de conservación a distintas escalas geográficas (Motta-Junior et al 2008) ya que la riqueza de especies es una medida natural y simple para describir la comunidad y la diversidad regional (Magurran 1988;Jiménez-Valverde and Hortal 2003;Fandiño and Giraudo 2010). Brown (2005) establece que la introducción de especies leñosas invasoras representa una amenaza para la diversidad biológica ya que altera los procesos ecosistémicos del suelo (i.e., ciclo de nutrientes y química del suelo, entre otros).…”

Non-passerine birds from Laguna Melincué Ramsar Site, Santa Fe province, Argentina

“…In the present checklist, updated with information from 12 more survey years, we add 35 species: four waterbird species from three families: Phoenicoparrus jamesi, Oreopholus ruficollis, Megaceryle torquata (Linnaeus, 1766) and Chloroceryle americana (Gmelin, 1788) and 31 non-passerine landbird species from nine families (Table 1). These 109 species represent almost half of the non-passerine birds reported by Fandiño and Giraudo (2010) for the whole of Santa Fe province (i.e., 231 species). These results confirm the importance of this wetland as a site of high environmental heterogeneity and biological diversity within a homogeneous and lowdiversity agricultural matrix (Di Giacomo et al 2005;Romano et al 2005;Giraudo et al 2008;Romano et al 2014).…”

“…Non-passerine birds from Laguna Melincué Ramsar site, Santa Fe province, Argentina abundances for the whole study period as very abundant (>10,000 observations), abundant (1,000-10,000 observations), scarce (100-1,000 observations), and rare (<100 observations) (Brandolin et al 2011). We followed Fandiño and Giraudo (2010) and Brandolin et al (2011) to classify species as 'residents' or 'migrants'. The latter were divided in 'Nearctic migrants' (i.e., species that nest in the Nearctic and then migrate to the south being recorded in the area in spring and summer), 'northern austral migrants' (i.e., species that nest in the area in spring and summer and then migrate to northern areas), 'southern austral migrants' (i.e., species that nest in southern Argentina in spring and summer and disperse to the study area in autumn and winter), 'Altitudinal Migrants' (i.e., species that nest in the High Andes in summer and migrate to the area in winter) and 'Partial Migrants' (i.e., species that move from the study area to other areas, but without any clear pattern).…”
