Species’ activity patterns are driven by the need to meet basic requirements of food, social interactions, movement, and rest, but often are influenced by a variety of biotic and abiotic factors. We used camera-trap data to describe and compare the activity patterns of the relatively poorly studied tayra (Eira barbara) across 10 populations distrib...

In Ecuador, the presence of melanistic individuals of Southern Tamandua Tamandua tetradactyla Linnaeus (1758) has been recognized but there has not been a formal report written about it. Neither has there been one on the observations or the collected specimens in museums. We present six records of melanism in Tamandua tetradactyla from southern Ecu...

Los patrones de actividad son indicadores espacio-temporales de las dinámicas inter e intraespecíficas en un ecosistema. Los estudios de grandes mamíferos en las estribaciones andinas del Ecuador son numerosos, sin embargo, la información asociada a patrones y niveles de actividad de fauna silvestre es escasa. En esta investigación presentamos los...

Los patrones y niveles de actividad de grandes mamíferos silvestres pueden ser considerados como indicadores temporales de gasto energético, esfuerzo en la búsqueda de alimento y exposición a riesgos. En este estudio estimamos los patrones de actividad del oso andino en tres localidades de los Andes centro orientales de Ecuador; e identificamos dif...

Los patrones de actividad son indicadores espacio-temporales relacionados con el gasto energético, esfuerzo en el forrajeo y exposición a riesgos. En esta investigación presentamos los resultados preliminares de las estimaciones de patrones de actividad del oso de anteojos y tapir andino en distintas localidades de las estribaciones centro-oriental...

We report the highest and southernmost documented records of 2 species of Ecuadorian birds: Sunbittern Eurypyga helias (Pallas, 1781) in the southern end of Podocarpus National Park and Black-necked Stilt Himantopus mexicanus (Statius Müller, 1776) in Yacuri National Park. Considering these and other records, both species might be expanding their r...

El Proyecto Paisajes-Vida Silvestre propone a través de diferentes iniciativas, cambiar el paradigma de conservación, integrando las áreas protegidas en la matriz circundante y viceversa. De esta manera, a través de la conectividad funcional se espera articular la conservación de la vida silvestre con actividades productivas sostenibles y la consec...

Twelve gecko species within the genus Phyllodactylus Gray, 1828 have been recorded from Ecuador to date (Torres-Carvajal et al., 2017). Eight of these are found exclusively in the Galápagos Islands, three on the mainland, and one species is present in both locations (Dixon and Huey, 1970; Torres-Carvajal, 2001; TorresCarvajal et al., 2017; Uetz et...

La fragmentación y destrucción del hábitat generan importantes efectos en los procesos ecológicos y las relaciones entre las especies y el ecosistema. La configuración de la cobertura vegetal del paisaje (esto es, la conectividad estructural) y la percepción de disponibilidad de recursos (esto es, la conectividad funcional) de cada especie influyen...

Los patrones de actividad de la fauna silvestre pueden reflejar indicadores temporales de gasto energético, esfuerzo en el forrajeo y exposición a riesgos (por ejemplo, relación presa- predador). Las investigaciones orientadas al conocimiento de los patrones de actividad del oso andino (Tremarctos ornatus) en el Ecuador son limitadas, por lo que en...

We document Lepidoblepharis conolepis from El Cielito, Carchi province, northern Ecuador. This record , the first record for Carchi province, represents a northward range extension of 90 km from the previously known occurences. All known occurrences of L. conolepis, including our new record, are restricted to the western slopes of the Ecuadorian An...

The Ecological Corridor “Llanganates Sangay” (CELS), is consider like an emblematic refuge of flora and fauna, for its strategic geographic location that hosts a variety of microcuencas, habitats and landscapes. Due to recent conformation of CELS, exists lack of information about its operationality; however, is imperative the need to generate speci...

We analyze α and β diversity of two abundant and easy to collect taxonomic groups in the Yasuní National Park: vascular plants and ants, in order to determine similarities and differences between species diversity and abundance. Different methodologies were used for each taxon. For the collection and identification of ants four study sites were cho...

Eira barbara Tayra has been reported across its geographic range from elevations between 0–2400 m, being rare above 1200 m. We report four records of E. barbara above 2600 m, obtained by using camera trapping. These records come from Reserva Natural Chamanapamba and Bosque Protector Cerro Candelaria, both located on the province of Tungurahua, east...

During September 2011 and March 2012 was conducted a monitoring of the mountain tapir (Tapirus pinchaque) in the cloud forest of the Nature Reserve Chamanapamba (NRC) located in Ulba-Baños. The NRC preserves pristine habitats that maintain connectivity with the Sangay National Park, constituting a primary area of study, this large mammal classified...

Monitoring was conducted between September 2011 and March 2012. For this purpose were established 10 transects in the three localities, 4 in the Chamanapamba Nature Reserve (RNC), 3 in the Cerro La Candelaria Protected Forest (BPCA) and 3 in the San Antonio’s Forest (BSA). Passive camera traps were used, which were recorded photographs and videos o...

Question
I want to model connectivity in pairwise mode. I prepared all the files in ASCII formats and stored them on my desktop for easy access. I followed the instructions on Julia but after hit running CS (Step 10), Julia stopped and returned a message of "ERROR: System error: opening file [...] permission denied" ( image attached). Does any of you could give me some guidance for resolving this?
Also, what is the number of parallel processes I should choose, and depending on what?
Thanks in advance.
