Genetic studies of various Prosopis species (Leguminosae, Section Algarobia) co- occurring in oases of the Atacama Desert (northern Chile)
(Wiley, 2021-03-01)In the Atacama Desert from northern Chile (19– 24°S), Prosopis (Leguminosae) individuals are restricted to oases that are unevenly distributed and isolated from each other by large stretches of barren landscape constituting ... -
Transcriptome survey of Patagonian southern beech Nothofagus nervosa (= N. Alpina): assembly, annotation and molecular marker discovery
(Genomics 13: 291 (2012), 2012-07-02)Nothofagus nervosa is one of the most emblematic native tree species of Patagonian temperate forests. Here, the shotgun RNA-sequencing (RNA-Seq) of the transcriptome of N. nervosa, including de novo assembly, functional ... -
Neurobehavioral evaluation and phytochemical characterization of a series of argentine valerian species
(Elsevier, 2020-12)Folkloric or galenic preparations of valerian roots and rhizomes have been used as sedatives/anxiolytics and sleep inducers since ancient times. “Valerianas” are plants that naturally grow in our region. Although some of ... -
Occupancy of avian foraging guilds in soybean fields and borders in Entre Ríos, Argentina: responses to vegetation structure and prey resources
(BMC, 2020-12)Reconciling agriculture and biodiversity conservation is a challenge given the growing demand for agricultural products. In recent decades, Argentina has witnessed agricultural expansion and intensification affecting ... -
Lethal and sublethal effects of the natural and healthy spinosad-based formulation Tracer™ on tadpoles of two neotropical species
(Springer, 2020-11)This paper presents the first acute toxicity data of the natural insecticide spinosad in amphibians. The sensitivity of two neotropical sympatric anuran species, Boana pulchella and Rhinella arenarum, to spinosad-based ... -
Glossy privet (Ligustrum lucidum) invasion decreases Chaco Serrano forest bird diversity but favors its seed dispersers
(Springer, 2020-11)Glossy privet (Ligustrum lucidum) is an aggressive invasive plant that replaces native forests and forms dense stands without understory in central Argentina. However, the consequences of these changes in terms of vegetation ... -
Combined effects of agrochemical contamination and forest loss on anuran diversity in agroecosystems of east-central Argentina
(Elsevier, 2020-11)Agricultural expansion and intensification has led globally to a rapid landscape structure change and high agrochemical use resulting in habitat loss and degraded environmental quality. Co-occurrence of landscape change ... -
Imidacloprid seed coating poses a risk of acute toxicity to small farmland birds: A weight-of-evidence analysis using data from the grayish baywing Agelaioides badius
(Elsevier, 2020-10)The aim of this study was to estimate the risk posed by imidacloprid (IMI) seed coating to passerine birds of the Pampa Region of Argentina using data specifically generated with the grayish baywing (Agelaioides badius). ... -
First test for eradication of beavers (Castor canadensis) in Tierra del Fuego, Argentina
(Springer, 2020-08)The North American beaver (Castor canadensis) was introduced in 1946 from Canada to Isla Grande de Tierra del Fuego to develop a fur industry. Their expansion to most of the habitats of Tierra del Fuego and their presence ... -
The problem with implementing fish farms in agricultural regions: A trial in a pampean pond highlights potential risks to both human and fish health
(Elsevier, 2020-09)The safety of creating fish farms in agricultural settings was evaluated by growing Piaractus mesopotamicus in a pond, while crops where cultivated in a nearby field under a pesticide application regime typical of the Pampa ... -
Using occupancy models to assess the direct and indirect impacts of agricultural expansion on species’ populations
(Springer, 2020-08)Land-use change is a global threat to biodiversity, but how land-use change affects species beyond the direct effect of habitat loss remains poorly understood. We developed an approach to isolate and map the direct and ... -
Trade‐offs between biodiversity and agriculture are moving targets in dynamic landscapes
(Wiley, 2020-07)Understanding how biodiversity responds to intensifying agriculture is critical to mitigating the trade‐offs between them. These trade‐offs are particularly strong in tropical and subtropical deforestation frontiers, yet ... -
The chromosome region including the earliness per se locus Eps-Am1 affects the duration of early developmental phases and spikelet number in diploid wheat
(Society for Experimental Biology, 2008-10)Earliness per se genes are those that regulate flowering time independently of vernalization and photoperiod, and are important for the fine tuning of flowering time and for the wide adaptation of wheat to different ... -
Frog somatic indices: Importance of considering allometric scaling, relation with body condition and seasonal variation in the frog Leptodactylus latrans
(Elsevier, 2020)Snout-vent length (SVL) and liver, gonad, fat bodies and carcass weight data from 661 individual Leptodactylus latrans frogs collected over ten years in the Pampa Region of Argentina were analyzed to evaluate the best ... -
Increasing synergistic effects of habitat destruction and hunting on mammals over three decades in the Gran Chaco
(2020-03-17)Habitat destruction and overexploitation are the main threats to biodiversity and where they co-occur, their combined impact is often larger than their individual one. Yet, detailed knowledge of the spatial footprints of ... -
Frog body condition: Basic assumptions, comparison of methods and characterization of natural variability with field data from Leptodactylus Latrans
(2020-01-08)Body weight and snout-vent length (SVL) data of 3006 individual Leptodactylus latrans frogs collected over ten years in the Pampa Region of Argentina were analyzed to evaluate the best approach for expressing body condition ... -
Increment coring induced traumatic resin ducts in white spruce but not in lodgepole pine
(2020-01-30)Injury from sampling increment cores may induce defense responses in trees, which may vary between species and reflect differing defense allocation strategies against attack by insects and pathogens. We recorded presence ... -
