Modelling beta diversity of aquatic macroinvertebrates in High Andean wetlands
Journal of Limnology, 2017 Central Andean Highlands represent a singular environment characterized by various extreme conditions. Among them, peatbogs are exceptional marshy habitats scattered throughout this arid and harsh area.

Separability of drag and thrust in undulatory animals and machines [PDF]
Sci. Rep. 4 , 7329, 2014, 2014 For nearly a century, researchers have tried to understand the swimming of aquatic animals in terms of a balance between the forward thrust from swimming movements and drag on the body. Prior approaches have failed to provide a separation of these two forces for undulatory swimmers such as lamprey and eels, where most parts of the body are ...

Neotropical Bird Migration During The Ice Ages: Orientation And Ecology [PDF]
, 1996 Reconstruction of breeding habitat of North American Neotropical migrants 18,000 years ago and 9,000 years ago indicated major shifts in both location and composition of plant communities relative to present conditions.

Detecting and modelling delayed density-dependence in abundance time series of a small mammal (Didelphis aurita) [PDF]
Sci. Rep. 6, 19553 (2016), 2017 We study the population size time series of a Neotropical small mammal with the intent of detecting and modelling population regulation processes generated by density-dependent factors and their possible delayed effects. The application of analysis tools based on principles of statistical generality are nowadays a common practice for describing these ...

Local and regional ecological morphology of dung beetle assemblages across four biogeographic regions [PDF]
, 2011 Aim Niche partitioning within species assemblages is thought to influence species packing and/or total niche space occupied. The evolution of dung beetles (Scarabaeinae) is likely to have been strongly influenced by inter-specific competition, leading to

Molecular Ecology Resources, EarlyView., 2023 Abstract Accurate taxonomic identification is foundational for effective species monitoring and management. When visual identifications are infeasible or inaccurate, genetic approaches provide a reliable alternative. However, these approaches are sometimes less viable (e.g., need for near real‐time results, remote locations, funding concerns, molecular

Revista Chilena de Entomología, 2022 We record for the first time the Darwin wasp species Photocryptus nigrosignatus (Kriechbaumer, 1901) parasitizing nests of the solitary wasp Sceliphron fistularium (Dahlbom, 1843) in the Amazonas state, Brazil, and provide new distribution records for ...

AnuraSet: A dataset for benchmarking Neotropical anuran calls identification in passive acoustic monitoring [PDF]
arXiv, 2023 Global change is predicted to induce shifts in anuran acoustic behavior, which can be studied through passive acoustic monitoring (PAM). Understanding changes in calling behavior requires the identification of anuran species, which is challenging due to the particular characteristics of neotropical soundscapes. In this paper, we introduce a large-scale

Seasonal variation in the diet of Lontra longicaudis in the Paraná River basin, Argentina [PDF]
, 2014 We studied the Neotropical otter ( Lontra longicaudis ) seasonal diet variations in the middle Paran á River valley, in central-northern Argentina, at the southern limit of its global range.
