Abstract:

Due to the seismicity of the country and especially to the geology of the province of Pichincha, it was considered important to obtain this equation in order to improve the structural design of future constructions since we do not have our own parameters to determine the mechanical properties of concrete. Based on previous investigations of the modulus of elasticity carried out in the country, it was identified that the current formula does not reflect the reality of the existing conditions since the derivation of this equation was determined in the USA whose characteristics of the materials a

Abstract:

Two new species of Burmeistera endemic to Ecuador are described and their relationship with other species are discussed. Burmeistera pterifolia has an extremely narrow distribution on the northwestern foothills of the Andes in the Pichincha province, and it is easily differentiated from its congeners by its pinnatilobate leaf margin and large calyx lobes. The second species, Burmeistera draconis, is recorded from the Zamora Chinchipe province. It is distinctive in possessing an irregularly bidentate leaf margin and cylindrical inflated fruits with short calyx lobes.

The species seems to have a habitat preference for patches of short Ericaceous growth, but occurs locally in mossy cloud forest, typically found in low densities. Adults sang throughout the year, usually from canopy but also from inside short Ericaceous growth.

Despite its proximity to the city of Quito (less than 5 km), Pululahua seems to have an average richness compared with other similar localities in the Ecuadorian Andes

Abstract:

In 2019, an extensive survey of the terrestrial gastropods from the Un poco del Chocó Nature Reserve (UPDC) was conducted, in order to assess the gastropod biodiversity and collect some preliminary data on their ecology. During this study, many new and poorly known taxa were found. This paper is the first dedicated to describing the gastropods from UPDC, starting with the Helicinidae. Helicina ecuadoriana K. Miller, 1879 and Bourciera intermedia Roosen & Dorado, 2022 are reported for the first time from UPDC. In addition, the genus Alcadia (Microalcadia) is reported from Ecuador for the fi

Abstract:

The investigation of linear erosion forms was carried out at the city of Quito (Equatorial Andes). The study was aimed to define the correlation between rill forms with different length parameters in the key-site area located nearby Zabala. It is stated that the rill forms with the length up to 50 m (58%) prevail. The gullies with the length of more than 200 m make 9% of all rill forms. Nevertheless, these gullies, as a rule, create main channels that provoke the formation of multiple side forms in the process of regressive erosion. The further development of the linear erosion causes the diss

A new species of Ripipteryx Newman (Orthoptera: Tridactyloidea: Ripipterygidae) is described from a fragment of primary Andean forest on the slopes of the extinct Pasochoa volcano in Pichincha Province, northern Ecuador. Ripipteryx pasochoensis sp. nov. is distinguished from congeners by the morphology of the male terminalia, particularly the structure of the subgenital plate. Based on colouration, modification of the subgenital plate and structure of the phallic complex, the new species is assigned to the Forceps Group and appears most closely related to Ripipteryx processata Günther.

Definition of priorities for maize diversity conservation in this region can be supported by the spatial identification of areas with a high eco-geographical and phenotypic diversity. Six hundred thirty-six maize samples were morphologically characterized using 14 descriptors and assigned to a distinctive race. Additionally, sampled farms were characterized by 12 environmental variables. From these data, maps of morphological and eco-geographical diversity were obtained by using technique

In the literature on growth, infrastructure, in addition to other factors, is identified as a determining element in the growth of regions from a long-term perspective. However, there are few studies where the unit of analysis is disaggregated down to the regional level. Therefore, this research aims to explore the importance of infrastructure (social and economic) in the economic growth of Ecuador´s provinces.

The behavioral repertoire of M. deliciosus is much more diverse than previously documented; it includes four mechanical phrases, two vocal sounds, and seven display behaviors
