(2023)Las ostras se abrirán para extraer los tejidos blandos, que se enjuagarán con agua destilada para eliminar la materia orgánica externa (MO). A continuación, estos tejidos se disolverán en hidróxido de potasio (KOH) al ... -
Therapeutic potential of hair follicle-derived stem cell intranasal transplantation in a rat model of ischemic stroke
(2022-07-25)Background Stem cell-based therapy has received considerable attention as a potential candidate in the treatment of ischemic stroke; however, employing an appropriate type of stem cells and an effective delivery route are ... -
Animal models of social stress: the dark side of social interactions
(2018-09)Social stress occurs in all social species, including humans, and shape both mental health and future interactions with conspecifics. Animal models of social stress are used to unravel the precise role of the main stress ... -
Comparaison de deux méthodes pour l’étude et le suivi des communautés coralligènes de Méditerranée occidentale : utilisation de prises de vues en photogrammétrie versus photoquadrats
(2023-07)Over the last few decades, Mediterranean ecosystems have been affected by severe heat waves, leading to massive mortality in many benthic species. These species belong and participate to the formation of one of the most ... -
Efectos intergeneracionales de la exposición crónica a microplásticos de baja densidad en el zooplancton: el caso del copépodo Paracalanus parvus en el Golfo de Nicoya, Costa Rica
(2023-09-07)The text discusses the widespread use of plastic, the increasing production of plastic waste, and its entry into the marine environment, primarily through rivers. Plastic waste in the oceans is broken down into microplastics, ... -
Landing manoeuvres predict roost-site preferences in bats
(2022-11-11)Roosts are vital for the survival of many species, and how individuals choose one site over another is affected by various factors. In bats, for example, species may use stiff roosts such as caves or compliant ones such ... -
Bat Assemblages along an Elevational Gradient in Costa Rica
(2022)Spatio-temporal patterns of species richness, Hill numbers, captures per species, feeding guilds, sex ratio, and biomass were studied in a Neotropical bat assemblage during 17 continuous months in four bands (low: 50–150, ... -
Bats mimic hymenopteran insect sounds to deter predators
(2022)This study explores interspecific acoustic mimicry in mammals, particularly focusing on the greater mouse-eared bat (Myotis myotis) distress calls. These calls imitate stinging bee and wasp sounds, aiming to deter avian ... -
Fungal communities in feces of the frugivorous bat Ectophylla alba and its highly specialized Ficus colubrinae diet
(2022)Background: Bats are important long-distance dispersers of many tropical plants, yet, by consuming fruits, they may disperse not only the plant’s seeds, but also the mycobiota within those fruits. We characterized the ... -
A review of Acianthera subgenus Brenesia (Orchidaceae, Pleurothallidinae), with a new species from Mexico
(2023)Background and Aims: Brenesia was originally proposed to accommodate an odd taxon among the Orchidaceae subtribe Pleurothallidinae. This species is characterized by its sessile leaves, secondary stems covered by inflated ... -
Malaxis dressleriana: A new orchid species honoring a botanist for all seasons
(2023-08)The genus Malaxis Sol. ex Sw. comprises about 300 species, predominantly found in pantropical regions with a few in temperate areas of the Americas, Asia, and Europe. Mexico has the highest concentration, with 71 species, ... -
Colombian Orchidaceae: A catalogue of the Pleurothallidinae
(2023-08-11)Colombia is a major biodiversity hotspot, having one of the richest orchid floras in the world. The country spans over a million square kilometers of land, hosting a multitude of different ecosystems thanks to the complexity ... -
Seasonality in the emission of contact calls in Spix’s disc-winged bats(Thyroptera tricolor) suggests a potential role in mate attraction
(2022)Multiple studies show that animals exhibit consistent individual differences in behavior, but they also experience short-term changes in their behavioral responses associated with seasonal events, most notably reproduction. ... -
Spatio‑temporal distribution and reproductive phenologyof Neotropical bat species in an altitudinal gradient in Costa Rica
(2022-01-14)We studied the altitudinal and temporal patterns of species abundance and reproductive status for 18 Neotropical bat species during 17 continuous months in four ranges (low 50, mid–low 500, mid–high 1000, and high 2000 ... -
Phalaenopsis schilleriana
(2004)El género Phalaenopsis, que consta de unas 60 especies, es uno de los más populares en la hibridación y la venta comercial, principalmente debido a la belleza, tamaño y duración de sus flores. Además, el crecimiento lento ... -
Diversidad y estructura genética de la danta Centroamericana (Tapirus Bairdii) en el noroeste de la cordillera de Talamanca y en el corredor biológico Tenorio-Miravalles, Costa Rica
(2023)Tapirus bairdii is the largest terrestrial herbivore living in Mesoamerica, distributed from southern Mexico to northwestern Colombia. Tapirs play relevant ecological roles as seed dispersers and nutrient cycling redistributors ... -
