Acoustic monitoring is used to assess biodiversity across large spatial and temporal scales. However, extracting meaningful information from data sets might be exceedingly time consuming. For this reason, acoustic indices have been proposed as proxies for monitoring. Although hold great promise standardizing analysis, the complexity of conditions requires careful examination relationship between an index underlying process interest. We evaluated 11 at two operational levels: (1) community...
Neotropical ecosystems are highly biodiverse; however, the excessive use of pesticides has polluted freshwaters, with deleterious effects on aquatic biota. This study aims to analyze concentrations active ingredients (a.i) and risks posed freshwater ecosystems. We compiled information from 1036 superficial water samples taken in Costa Rica between 2009 2019. calculated detection frequency for 85 a.i. compared international regulations. The most frequently detected were diuron, ametryn,...
Specialist species are defined by their restricted range of tolerated environmental conditions and required resources. For example, in the New World leaf-nosed bats (Phyllostomidae), specialization diet has been linked to morphological behavioral innovations (i.e., skull form, foraging behaviors) that facilitate occupation new ecological niches these animals. Here, we use Honduran white bat, Ectophylla alba, as a model test responses narrow diet: one based on figs Ficus colubrinae...
[Introducción]: La evaluación de la biomasa y el desarrollo modelos es un elemento clave para determinar potencial mitigación del cambio climático los ecosistemas forestales. Los bosques plantados año tras ocupan mayor área, también adquieren relevancia en almacenamiento carbono, pero existe poca información sobre cuantificación carbono diversidad especies, sitios grado manejo. [Objetivo]: El objetivo estudio fue evaluar distintos componentes o fracciones (hojas, ramas, fuste, raíz) árbol....
The Puerto Rican Coqui, Eleutherodactylus coqui Thomas, 1966, is widespread and abundant in Rico (Woolbright et al. 2006), where the frog's constant nocturnal vocalizations make it an iconic beloved representative species (Beard Pitt 2012).However, outside its native range, E. often less appreciated even considered a pest.Eleutherodactylus among 100 worst invasive world (Lowe 2004), particularly because of invasion Hawaiian Archipelago (Kalnicky 2014).In Hawaii population can reach
We assessed the structural complexity of vegetation, birds and soundscapes in two areas Braulio Carrillo National Park, Costa Rica, with different road exposure, as baseline information for conservation management. measured vegetation structure complexity, surveyed recorded an area adjacent to Highway 32 (Quebrada) another 20 km away (Ceibo). Quebrada presented a more open forest lower density trees shrubs; evenness higher acoustic bioacoustic activity sound pressure level; bird abundance...
Los cambios producidos por actividades humanas sobre los ecosistemas acuáticos reducen y reconfiguran hábitats disponibles. Por ello, el objetivo de este estudio fue evaluar la selección hábitat nutria neotropical (Lontra longicaudis), en zonas con influencia represa hidroeléctrica del río Peñas Blancas algunos sus tributarios, fin recomendar acciones para conservación nutria. Se muestreó tres tributarios busca indicios medición siete variables ambientales determinar probabilidad ocurrencia...
Antimicrobial resistance poses a growing threat to human health, yet its implications for wildlife remain subject of ongoing research. River otters inhabiting the Peñas Blancas face exposure various anthropogenic activities in their habitat, potentially leading accumulation antibiotic-resistant genes (ARGs) with unknown consequences health. This study aimed identify specific ARGs otter feces from this river basin, employing quantitative polymerase chain reaction (qPCR), DNA sequencing ARGs,...
The Puerto Rican Common coqui frog (Eleutherodactylus coqui) has a long history as an invasive species in places such Hawaii. Since its introduction Costa Rica, scarce information is available to understand why and how the habitat Turrialba town suitable for species. Our goal was analyze selection of E. identify if there are key features that explained success there. We measured 9 site variables may affect 92 survey units 10 m radius distributed over 500 from point. registered...
Bull shark (Carcharhinus leucas) is a near-threatened elasmobranch species capable of moving between the fresh and salty waters tropical subtropical coastal areas, for which we still lack important ecological information. During their first years life, bull sharks use estuarine systems as nursery making them highly susceptible to environmental anthropogenic pressures. We studied trophic ecology juveniles found in Coyote estuary, potential area Costa Rica, understand impact further declines...
La divergencia de caracteres son diferencias en el tamaño especies simpátricas, estrechamente relacionadas que, como hipótesis focal se asume que semejantes no podrían coexistir sin segregarse dada la competencia interespecífica. Si interespecífica generó segregación permitiendo coexistencia simpatría, preguntamos ¿cuál es distancia ecológica entre estas permite esa coexistencia? Entonces, nuestro objetivo fue conocer basados las dimensiones del pico y longitud total algunas aves...
ResumenA lo largo de las últimas décadas, los bosques en Centroamérica han sufrido grandes cambios usos la tierra, así como reducción diferentes tipos bosques. Los efectos esta reducción, sumado a estos cambios, podrían ser una fuerte amenaza para diversidad murciélagos, puesto que animales se especializan cazar o buscar alimento ambientes específicos. Dado hay conocimiento limitado sobre situación actual riesgo estado conservación murciélagos Honduras y especial, insectívoros, evaluaron...
Habitat selection of the neotropical otter (Lontra longicaudis) was evaluated in Iberá Natural Reserve, province Corrientes, Argentina, from July to November 2014. We sampled 99 segments 300 m length, which were located lagoon, Paraná and Arroyo Carambola. Each segment visited create detection / non-detection histories otter. Environmental attributes measured, such as environment type, vegetation cover, influence alligator (Caiman latirostris C. yacare). These used occupation models. The...
