Literature on the predation ecology of Amazonian canids is scarce, especially for the two rarely observed canids; Speothos venaticus (Bush Dog) and Atelocynus microtis (Short-eared Dog). Between 2000 and 2005 we documented one observation of predation of a A. microtis from southeastern Peru and an observation of S. venaticus predation from southwes...

Several mammal inventories have been reported from the lowland Amazon of Madre de Dios, Peru, but few have been reported for the Las Piedras River. Here we present a list of mammal species from the Las Piedras River. Over a period of seven years (2013–2020), we recorded the presence of mammal species, excluding bats and small rodents, using camera...

Although behavior of E. murinus was broadly described over a century ago, observations of predation by E. murinus are rare. Some evidence suggests that it may target sites when hunting. We report details of six livestock depredation events at a single locality near Puerto Maldonado, Peru. Additionally, we compare positions of three radio-tagged sna...

The Banded Galliwasp (Diploglossus fasciatus), a little-studied anguimorph lizard in South America, has been historically perceived as terrestrial. Recent observations challenge this notion, revealing arboreal behavior in the species. We present three new instances of D. fasciatus observed in arboreal habitats, including an adult found 30 meters hi...

We present an assessment of the tropical peatlands in the upper-Ucayali Valley in central Peru—an Amazonian region that has been largely ignored in ecological and wetlands research. We focused on groundtruthing and identifying the strongest landscape-level predictors of peat depth. The 2015 product from the Peruvian Ministry of the Environment (MIN...

Records of Galictis vittata (Greater Grison) from the Amazon basin are sparse, particularly in the Madre de Dios region, where only three records have been published. This study elaborates on seven observations of Galictis vittata within and near small interior forest streams of the Las Piedras tributary in Madre de Dios, Peru. While G. vittata inh...

The short-eared dog (Atelocynus microtis) is the only endemic Amazonian canid species, which is also elusive and rarely recorded across its distribution, making it one of the least known canid species in the world. Even though it is considered to be a carnivore species, it has been reported to consume other food items, such as fruits. However, no c...

While elucidating the evolutionary trajectory of green anacondas, we previously documented the existence of two distinct species, Eunectes akayima sp. nov. and Eunectes murinus (Linnaeus, 1758), that separated approximately 10 million years ago. Our research integrates a novel molecular clock approach, focuses on tectonic plate movements with fossi...

This study presents a rare observation of a predator-prey interaction between a tayra (Eira barbara), a semi-arboreal predator, and a group of spider monkeys (Ateles chamek) in Madre de Dios, Peru. The observed pursuit of an A. chamek mother and infant by the E. barbara for an extended time period highlights the evasive tactics and aggressive respo...

Habitats, fauna lists, infrastructure, accessibility, and research history at the Las Piedras Biodiversity Station.

Este estudio aborda la ecología de depredación poco estudiada de Atelocynus microtis, un cánido amazónico raro y casi amenazado. Detallamos eventos de depredación por la especie de félido, Panthera onca (Jaguar), observados en el sureste de Perú en 2004. Los descubrimientos se realizaron durante nuestra investigación en curso, que incluye seguimien...

We present observations of Chironius fuscus (Brown Sipo) partially buried for extended periods within Leaf-Cutter Ant nests.

We describe an observation of a fishing spider (Ancylometes sp.) killing and partially consuming an Imantodes cenchoa (Blunt-headed Tree Snake) in Tambopata, Peru.

We describe an observation of a Tantilla melanocephala basking on a trail near the Los Amigos and Madre de Dios rivers, Southeastern Peru.

Previous accounts categorized Diploglossus fasciatus as a terrestrial lizard with limited ecological information. However, our observation in Peru revealed unexpected behaviors. A D. fasciatus perched high in a tree, displaying arboreal tendencies, and exhibited a remarkable escape mechanism by jumping from its perch. Burrowing behavior was also do...

We describe an incident of a wild ocelot that attacked a group of people in Southeastern Peru. Based on recorded evidence and scientific literature, we hypothesize disease affecting the central nervous system or human‐induced trauma as possible explanations for this abnormal behaviour.

An observation of a Urubitinga urubitinga (Great Black Hawk; Accipitridae) attempting to predate upon a Platemys platycephala near the confluence of the Los Amigos and Madre de Dios Rivers in Southeastern Peru. Full text article available at: https://ssarherps.org/herpetological-review-pdfs

We report a predation event by the poorly described short-eared dog (Atelocynus microtis) on a breeding congregation of Osteocephalus taurinus

We provide two new ophidian prey items for Drymarchon corais and a description of the events observed near the Las Piedras River, Madre de Dios, Peru.

We observed an adult Musurana (Clelia clelia) consuming a larger Spilotes pullatus

We report an observation of an Ancylometes sp. killing and consuming an Engystomops petersi in Madre de Dios, Peru.

We report feeding events of juvenile Paleosuchus trigonatus on two aquatic vertebrates and an invertebrate. Full-text article available at: https://ssarherps.org/herpetological-review-pdfs/
