Bauhinia affinis (Fabaceae) : una nueva cita para la flora argentina
(Instituto de Botánica Darwinion, 1996)Bauhinia affinis Vogel is reported for the first time in the NE extreme of Argentina. The number of species of the genus recorded for the country is increased to 7. The species is described and illustrated indicating ist ... -
Behavioral and physiological changes in the passerine Agelaioides badius following the ingestion of coated seeds with imidacloprid in a 30-day experiment
(Elsevier, 2023-12)The wide use of neonicotinoid seed treatment represents a hazard for farmland birds that feed on treated seeds. This study aimed to characterize the long-term effects of the neonicotinoid imidacloprid (IMI) in the passerine ... -
Behavioral and physiological response of the passerine bird agelaioides badius to seeds coated with imidacloprid.
(Springer, 2023-09-01)Neonicotinoids are globally used insecticides, and there are increasing evidence on their negative efects on birds. This study is aimed at characterizing the behavioral and physiological efects of the neonicotinoid ... -
Biodiversity loss in deforestation frontiers: Linking occupancy modelling and physiological stress indicators to understand local extinctions
(Elsevier, 2019-05-27)Tropical deforestation is a main driver of the global biodiversity crisis. Impact assessments typically focus on species' presence, which means impacts are detected when local extinctions have occurred – and thus when it ... -
Biological evaluation of Valeriana extracts from Argentina with potent cholinesterase inhibition for the treatment of neurodegenerative disorders and their comorbidities the case of Valeriana carnosa Sm. (Caprifoliaceae) studied in mice
(MDPI, 2023-01-01)Alzheimer’s disease (AD) is a neurodegenerative disorder whose pathophysiology in cludes the abnormal accumulation of proteins (e.g., β-amyloid), oxidative stress, and alterations in neurotransmitter levels, mainly ... -
Biomarker and hematological fieldwork with amphibians: is it necessary to sample all night?
(Springer, 2020-03)In the context of the global amphibian crisis, biomonitoring constitutes a valuable assessment tool to provide critical up to date information on the status and health of amphibians worldwide. The aim of the current study ... -
Biomonitoring of alterations in fish that inhabit anthropic aquatic environments in a basin from semi-arid regions
(MDPI, 2023-01-12)Industrial, agricultural, and urban areas can be sources of pollution and a cause of habitat fragmentation. The Conlara River located in the northeast of San Luis Province suffers different environmental pressures along ... -
Bird occupancy in intensively managed agroecosystems under large-scale organic and conventional farming in Argentina: A multi-species approach
(Elsevier, 2021-09)Several studies in European and North American agroecosystems conclude that organic farming benefits birds compared to conventional farming. Nevertheless, there are some biases toward these geographic regions and farm size. ... -
Both Volatiles and Cuticular Plant Compounds Determine Oviposition of the Willow Sawfly Nematus oligospilus on Leaves of Salix spp. (Salicaceae)
(Springer, 2015-11)Plant volatile organic compounds play a role in selection of host plants by herbivorous insects. Once the insect reaches the plant, contact cues determine host acceptance. Although the willow sawfly Nematus oligospilus ... -
Brazilian Flora 2020: Leveraging the power of a collaborative scientific network
(Wiley, 2022-02)The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiver sity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. ... -
Breeding value predictive accuracy for scarcely recorded traits in a Eucalyptus grandis breeding population using genomic selection and data on predictor traits
(Springer, 2023-07-18)Genomic selection methods are particularly useful for traits that are difcult or expensive to measure. We investigated the impact of using predictor growth traits and/or genomic information to increase the breeding value ... -
Carbon emissions from agricultural expansion and intensification in the Chaco
(Wiley, 2017-05)Carbon emissions from land‐use changes in tropical dry forest systems are poorly understood, although they are likely globally significant. The South American Chaco has recently emerged as a hot spot of agricultural expansion ... -
Carotenoids gene markers for sweetpotato (Ipomoea batatas L. Lam): applications in genetic mapping, diversity evaluation and cross‑species transference
(Springer, 2014-04)Carotenoids play essential biological roles in plants, and genes involved in the carotenoid biosynthesis pathway are evolutionarily conserved. Orange sweetpotato is an important source of β-carotene, a precursor of vitamin ... -
Changes in bird assemblages in a wetland ecosystem after 14 years of intensified cattle farming
(2018-05)Human activities have modified wetlands all over the word. Water control structures that are frequently implemented in these ecosystems to keep lands free of flooding can decrease or degrade habitat for biodiversity. The ... -
Characterization of functional SSR markers in Prosopis alba and their transferability across Prosopis species
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (España), 2015)Aim of study: The aim of the study was to characterize functional microsatellite markers in Prosopis alba and examine the transferability to species from the Prosopis genus. Area of the study: samples were obtained from ... -
Characterization of glandular trichomes of Minthostachys verticillata “peperina” from northwest and central Argentina: relation with essential oil content
(2016)Minthostachys verticillata is an endemic species in Argentina that shows higher contents of essential oils (EO %, v/w) in plants from the central area than in those from the northwest. Although the reason for this difference ... -
Characterization of the repetitive DNA landscape in wheat homeologous group 4 chromosomes
(2015)Background: The number and complexity of repetitive elements varies between species, being in general most represented in those with larger genomes. Combining the flow-sorted chromosome arms approach to genome analysis ... -
Chromosome studies in southern species of Mimosa (Fabaceae, Mimosoideae) and their taxonomic and evolutionary inferences
(2014-05)In this work, chromosome numbers and karyotype parameters of 36 taxa of the genus Mimosa were studied, especially from the southern South America center of diversification. Results support that x = 13 is the basic chromosome ... -
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 ... -
