A case of a non-fatal crocodile attack on a human was reported on the banks of the Segovia River on the Honduras and Nicaragua border. The 12-year-old girl survived the attack, on…

In Mexico opossums are difficult to find, and much of their natural history, ecology, and behavior are unknown. Through photographic and visual records, we obtained data on the pr…

We provide new records of Neogale frenata and Potos flavus, two carnivores with elusive behaviors that are challenging to observe in their natural habitats. Through direct records…

Laguna Blanca National Park (LBNP) is located in the mid-west of Neuquén Province, Argentina. It was created in 1940 with the aim of conserving the nesting and breeding habitats o…

Herein we add eight new country records to Panama’s caddisfly fauna (Insecta, Trichoptera): Hydropsychidae – Leptonema turrialbum Flint, McAlpine & Ross, 1987; Polycentropodidae –…

Domestic dogs (Canis lupus familiaris) are recognised worldwide not only as man’s best friend, but also as a form of anthropogenic edge effect impacting wildlife through predation…

Non sustainable land uses are disturbing natural habitats and wild animals’ ecology worldwide. Nevertheless, the sensitisation of key actors combined with research and a consequen…

The mammal community of the Coastal Range of southern Chile has been little studied even though they inhabit an environment under severe threats due to anthropic disturbance. Duri…

The caddisfly genus Protoptila (Trichoptera, Glossosomatidae) in Panama is currently represented by 15 species, including four endemic species and 11 species also found in Costa R…

The study of vegetative and reproductive phenophases of plants is critical for understanding aspects related to plant behavior in different environments. In the tropics, there is …

Fish populations in environments with a high degree of geographic isolation may be prone to mutations expressed in the phenotypes. These mutations may be related to color pattern,…

Although spiders and land planarians constitute diverse groups of terrestrial predators, interactions between them are still unknown. Here, we describe a predatory event of a land…

Roads severely affect the health of ecosystems across the globe by fragmenting and diminishing habitats, reducing population connectivity, and increasing animal mortality. Wildlif…

Small mammals, particularly rodents, are often important seed-dispersal agents in Neotropical forests. Directional seed dispersal into tree-fall gaps may enhance seedling survival…

We present the first records of the post-release follow-up and monitoring of a rehabilitated two-toed sloth (Choloepus hoffmanni) as well as freezing behavior and an inferred anta…
