International Journal for Parasitology: Parasites and Wildlife, 2023 The genus Serpinema Yeh, 1960 allocates parasitic nematodes of freshwater turtles distributed across the Oriental, Neotropical, and Palearctic regions. Five of 10 valid species of the genus Serpinema occur in the Neotropical region, and three have been ...

A new species of Falsocaenia (Coleoptera: Lycidae) from Brazil
Iheringia: Série Zoologia, 2019 A new species of Lycidae, Falsocaenia santatereza sp. nov. is described and illustrated. This species is a member of a Müllerian mimicry ring from the Atlantic Forest in Brazil, presenting color pattern also found in other sites of Neotropical region ...

Target capture and massively parallel sequencing of ultraconserved elements (UCEs) for comparative studies at shallow evolutionary time scales [PDF]
(2014) Systematic Biology 63: 83-95, 2013 Comparative genetic studies of non-model organisms are transforming rapidly due to major advances in sequencing technology. A limiting factor in these studies has been the identification and screening of orthologous loci across an evolutionarily distant set of taxa. Here, we evaluate the efficacy of genomic markers targeting ultraconserved DNA elements

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 ...

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

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 ...

Eliminating COVID-19: The Impact of Travel and Timing [PDF]
Communications Physics 3, 204 (2020), 2020 We analyze the spread of COVID-19 by considering the transmission of the disease among individuals both within and between regions. A set of regions can be defined as any partition of a population such that travel/social contact within each region far exceeds that between them.

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
