We describe a new species native to Ecuador and Peru, Miconia complanata. This species has been collected from two different localities: Parque Nacional Podocarpus (Ecuador) and Cordillera del Cóndor (Ecuador and Peru). The strongly quadrangular to winged stem, ridged nodes and coriaceous leaves make this species distinctive even within a large genus. © 2017 The New York Botanical Garden

We describe a new species of frog of the genus Chiasmocleis from the montane forests of southeastern Ecuador, at the western slopes of Cordillera del Cóndor, between 1,224-1,630 m of elevation. Based on new sequences of mitochondrial and nuclear DNA we present phylogenetic relationships of the new species and its congeners. The phylogeny shows a close relationship to C. antenori, C. carvalhoi, C. magnova and C. tridactyla. The new species is part of a clade of species that were previously assigned to the genus Syncope. This clade has a sister relationship to a clade that contains all remaining species of Chiasmocleis. The new species differs from its congeners by its reddish-brown to dark-brown (sepia) dorsum with minute yellowish-white spots. Chiasmocleis parkeri sp. nov. is similar to Chiasmocleis antenori in lacking digit I of both hands and feet but Chiasmocleis parkeri differs in coloration, arrangement and size of pale spots, and the absence of a pale line in the canthal region. We describe the calls, which are characterized by having nonpulsed notes, and we provide ecological data from the type locality and adjacent areas. © 2017, Universidade de Sao Paulo.

The introduction and conservation of field margins have been proposed as an intervention to counteract the decline in farmland biodiversity. However, how these margins can affect the movement of species and individuals (i.e. spillover) of natural enemies between field margins and crop is still unclear. In this work, we investigated the spillover of two different groups of natural enemies: tachinids (Diptera: Tachinidae) and aphidophagous hoverflies (Diptera: Syrphidae). For comparison we also investigated the response of non-aphidophagous hoverflies. We examined the spillover from two types of field margin (grass margin vs. hedgerow + grass margin) to adjacent maize fields located in landscapes with different proportion of arable land. The spillover of natural enemies was affected by the field margins, but the response varied between insect groups. The spillover of tachinids was higher from the grass margin than from hedgerows, suggesting that the spillover of this group may be related to the low contrast between the vegetation structure of the margin and the crop. In contrast to tachinids, the abundance of aphidophagous hoverflies was higher toward the center of the crop field, independently of the type of field margin. The spillover of non-aphidophagous hoverflies was not affected by the type of field margin. These species were only affected by the landscape composition as their species richness and abundance were higher in landscapes with low amounts of arable land. Measures focusing on the creation and management of field margins need to consider the local contrast between field margins and crops in relation to the life-history traits of different taxa. © 2015 Gesellschaft für Ökologie.

Stolzmann's crab eating rat Ichthyomys stolzmanni is known from six locaties, two of those in the eastern slopes of Ecuador and four in southeastern Peru. We recorded a male specimen in the Jurumbuno River, on the eastern slopes of Ecuador at the province of Morona Santiago. We described the body and cranial characteristics, which are within the range known for the species, except that the tail is bicolored to the medial portion and the rear half is uniformly dark. The digestive tract contained traces of insects (Corydalus sp.), shrimps (Macrobrachium sp.), and isopods (Artystone trisibia); the latter parasitizes fish, and this is the first report of this parasite in the diet of I. stolzmanni. Our record in the Jurumbuno River is the third locality in Ecuador for the species studied, 40 years after its previous capture. © 2016 Asociación Mexicana de Mastozoología.

We report the southernmost record of Cruziohyla craspedopus in Ecuador. An adult female was collected in the province of Zamora Chinchipe in southern Ecuador in the Cordillera del Condor. This record increases the previously reported altitudinal range for the species by 468 m and extends the distribution by 105 km to the south. © 2015 Check List and Authors.

We provide the first detailed description of the diet of Burrowing Owls (Athene cunicularia) for Ecuador, based on an analysis of 408 pellets collected from one locality in the north and one in the south of the central dry Andean Valley. Our results are consistent with previous studies in the Neotropics that document the importance of insects in the diet. Rodents made up 78.8% of the biomass in our sample. Additionally, we highlight the first record of the Andean eared mouse Phyllotis andium in a xeric environment, which was identified in the pellets. © 2016, Sociedade Brasileira de Ornitologia.

We analyzed 107 owl pellets and determined 300 prey items grouped into 21 species. The pellets were collected at two locations with different environments: Los Santiagos and La Ciénaga in the province of Chimborazo and Manabí in western Ecuador. Our analysis revealed a diet mostly comprised on small mammals, especially rodents which constituted 80%. Among the most abundant prey were Oligoryzomys sp. which accounted for 38.7% of the diet in Los Santiagos’ samples and Sigmodon peruanus 33.6% in La Ciénaga, being 22.5% and 41% respectively of the total biomass consumed at each site. The crab-eating rat Ichthyomys hydrobates is first reported in this owl’s diet and in the locality of Los Santiagos. This record extends the distributional range of I. hydrobates to southwest Ecuador by about 200 km. © 2015, Universidade de Sao Paulo. All rights reserved.

Leucism is a partial hypopigmentary congenital disorder that indicates low levels of genetic diversity and is considered to be an unusual trait in wild populations. In continental America, few cases of abnormal coloration in vertebrates have been recorded. This feature can increase the selective pressure on individuals who have it, and can result from population isolation which, in turn, could act as an alarming indicator of environmental change. This condition has not been reported previously in genera of small rodent such as Akodon, Nephelomys, Thomasomys, Trasandinomys and Mesomys. Therefore, the aim of this note is to report 38 cases of leucism found in eight rodent species for the first time: Akodon mollis (n = 7), Nephelomys albigularis (n = 7), N. moerex (n = 18), Transandinomys talamancae (n = 2), Thomasomys auricularis (n = 1), T. taczanowskii (n = 1), T. paramorum (n = 1) and Mesomys hispidus (n = 1). © 2016 Asociación Mexicana de Mastozoología.

We describe a new species, a medium size terrestrial frog (LRC 21.7-24.9 mm in females, and 15.2-17.8 mm in males); belong to the Pristimantis genus, from the sandstone plateau of the Cordillera del Condor at southeastern Ecuador, at 2300 m high. The new species differs from its congeners in Ecuador for its distinctive coloration pattern, ochraceous brown dorsal surface with numerous yellow spots, tympanic membrane, short fingers of the front and rear legs, and exclusive microhabitats in terrestrial bromeliads. They release modulated frequency and long calls, compoused of 6-8 notes and 1 harmonic. The description of Pristimantis paquishae sp. nov., is the result of a summary herpetofauna information in one of the remote and less known sandstone plateaus in the Cordillera del Condor. © 2014, Universidade de Sao Paulo.

Information is presented on morphological variation in the frog, Phyllomedusa ecuatoriana, with a description ot the tadpole, vocalizations, and notes on its natural history and distribution, based on material recently collected in the Cordillera del Cóndor, Zamora Chinchipe Province, Ecuador. Phyllomedusa ecuatoriana is of médium size (male SVL length 46.1 to 55.4 mm; female SVL 72.2 mm). The tapole (Gosner stage 26) has a dentary formula of 2 (2)/3 (1); tooth row P3 is smaller than P1 and P2. The tadpoles develop in pools of various sizes in turbid water stained by the presence of tanins. The vocalizations are modulated frequencies, with the dominant frequency averaging 1.53 kHz; the calls are composed of a single note and 2-3 pulses. Adult frogs feed primarily on spiders (20[%]) of the family Argiopidae. © 2014, Universidade de Sao Paulo. All rights reserved.
