A small protected area facilitates persistence of a large carnivore in a ranching landscape
Pereira, Javier Adolfo; Thompson, Jeffrey; Di Bitetti, Mario S.; Fracassi, Natalia; Paviolo, Agustín; Fameli, Alberto F.; Novaro, Andrés J. (Elsevier, 2020-05)Assessments of the role that small (<500 km2) protected areas play in conservation of large carnivores in landscapes where the species are persecuted are scarce. Using camera-trap sampling we estimated puma (Puma concolor) ... -
Activity patterns of the marsh deer: Effects of proxies of human movement, cattle presence, and moon phases on its behavior
Guerisoli, María de las Mercedes; Fergnani, Darío Martín; Fracassi, Natalia; Thompson, Jeffrey J.; Pereira, Javier Adolfo (Wiley, 2023-02)Activity is an important aspect of animal behavior. Intrinsic and extrinsic factors can shape species activity patterns, which can alter and reshape several ecological aspects of the species. Human disturbance is known to ... -

Fracassi, Natalia; Sica, Yanina Vanesa; Magnano, Andrea Laura; Vaccaro, Anahí; Landó, Roberto; Artero, Diego F.; Gavier Pizarro, Gregorio Ignacio; Bó, Roberto; Somma, Daniel Jorge; Quintana, Ruben D.; Rodriguez, María José; Cabanne, Gustavo Sebastián (Aves Argentinas y Asociación Ornitológica del Plata, 2021-12)The Delta of the Paraná River, one of the most important wetlands in South America, harbors subtropical and temperate bird species. Although this region is key for biodiversity conservation, aspects such as species composition ... -
Conservation of the largest cervid of South America : interactions between people and the Vulnerable marsh deer Blastocerus dichotomus
Iezzi, María Eugenia; Fracassi, Natalia; Pereira, Javier Adolfo (Cambridge University Press, 2017-07)Wild ungulates, and particularly deer, can cause severe damage to commercial plantations, resulting in reduced tolerance of their presence by forestry producers. The marsh deer Blastocerus dichotomus, categorized as ... -
Determinants of capybara presence in afforestations of the lower delta of the Paraná river, Argentina
Fracassi, Natalia; Buchter, Wendy M.; Pereira, Javier Adolfo; Borodowski, Esteban Daniel; Somma, Daniel Jorge (Taylor & Francis, 2015)The delta of the Paraná River in Argentina represents the southernmost stronghold for capybaras (Hydrochoerus hydrochaeris), but this area is highly modified due to commercial afforestations with Salicaceae. Water management ... -
Estrategias de conservación de la biodiversidad en paisajes forestales del bajo Delta del Paraná - Uniendo los actores clave de la región
Fracassi, Natalia; Pereira, Javier Adolfo; Mujica, Gerardo Oscar; Hauri, Bernardo; Quintana, Rúben Darío (Sociedad Argentina para el Estudio de los Mamíferos (SAREM), 2017-07)Las consecuencias de las prácticas forestales sobre la biodiversidad varían según el manejo silvícola, del agua y el hábitat sustituido. Las plantaciones forestales pueden ser diseñadas y manejadas para preservar las ... -
Extreme flooding increases poaching mortality in the southernmost stronghold of the endangered marsh deer
Pereira, Javier Adolfo; Varela, Diego; Thompson, Jeffrey J.; Lartigau, Bernardo V.; Fracassi, Natalia; Kittlein, Marcelo J. (Sociedad Argentina para el Estudio de los Mamíferos (SAREM), 2023-01)Extreme stochastic perturbations can affect population dynamics, but quantitative assessments are scarce for threatened species. The 2015-2016 El Niño-Southern Oscillation (ENSO) caused extreme flooding in the Delta of the ... -
First records of pigmentation anomalies in the marsh deer at its southernmost stronghold: a warning message?
Pereira, Javier Adolfo; Wolfenson, Laura I.; Artero, Diego F.; Argerich, Esteban C.; Varela, Diego; Fracassi, Natalia (Springer, 2023-05)Pigmentation anomalies (e.g., albinism, leucism) in Neotropical mammals are considered rare. Identifying the spatiotemporal distribution and prevalence of pigmentation anomalies is important to better assess the evolutionary ... -
