Criterios para determinar la edad de pollos de Flamenco Austral (Phoenicopterus chilensis) en cautiverio basadas en características del plumaje [PDF]
, 2018 Many aspects of the breeding biology of the Chilean Flamingo (Phoenicopterus chilensis) are still unknown. We studied captive breeding Chilean Flamingos at La Plata Zoo, Buenos Aires, Argentina between February and July 2014 to document chick‐aging ...

Spiroxys contortus (Rudolphi, 1819) and Hedruris orestiae (Moniez, 1889) in Argentine turtles [PDF]
, 2016 Knowledge of parasites in turtles is scarce,particularly with regard to freshwater turtles of SouthAmerica. Here, we describe the association of Spiroxyscontortus (Rudolphi, 1819) in Phrynops hilarii (Duméril& Bibron, 1835) and S.

Journal of Animal Ecology, EarlyView.This study reveals that tropical butterfly communities show remarkably consistent elevational patterns of diversity and phylogenetic structure across regions with contrasting evolutionary histories, demonstrating how regional species pools and local ecological factors jointly shape biodiversity along altitudinal gradients.

Unusual importance of insectivory in the diet of the Neotropical otter, Lontra annectens (Major, 1897) (Mammalia, Carnivora) [PDF]
Neotropical Biology and ConservationThe Neotropical otter, Lontra annectens, is a predator specialized in aquatic prey, and the main diet of this otter is fish, supplemented mainly by crustaceans and opportunistically by mollusks, insects, and vertebrates such as mammals, amphibians, birds,

The predatory behavior of ants: an impressive panoply of morphological adaptations
Insect Science, EarlyView.This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Integrative Zoology, EarlyView.Male weaponry evolution is often linked to male–male competition, but its relationship with breeding site type remains unclear. Using Leptodactylinae frogs, we found a macroevolutionary correlation between breeding site type and weapon evolution. Also, gains and losses of weapons occurred more frequently in exposed‐breeding sites, an unexpected finding.
