Vulnerability of marine megafauna to global at-sea anthropogenic threats. [PDF]

open access: yesConserv Biol
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

Reproductive biology, distribution and abundance of Squalus megalops (Macleay, 1881) and Squalus mitsukurii (Jordan & Snyder, 1903) off southern Brazil, southwest Atlantic. [PDF]

open access: yesJ Fish Biol
Abstract Squalus megalops and Squalus mitsukurii are recognized as the most abundant Squalus species in the southern Brazil region. Currently, S. megalops is listed as ‘least concern’ (LC) and S. mitsukurii as ‘endangered’ (EN). However, at the regional level, both species are classified as ‘data deficient’ – DD, due to the lack of population local ...

Pendular mechanism determinants and elastic energy usage during walking of obese and non‐obese children

open access: yesExperimental Physiology, Volume 108, Issue 11, Page 1400-1408, 1 November 2023., 2023
Abstract The mechanical and metabolic responses of walking by obese children are not yet well understood. The objectives of this study were (1) to compare the pendular mechanism (recovery, phase shift by α and β values, and ratio between forward and vertical mechanical work), the maximum possible elastic energy usage and the bilateral coordination ...

Tracking marine tetrapod carcasses using a low‐cost mixed methodology with GPS trackers, passive drifters and citizen science

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 9, Page 2354-2361, September 2023., 2023
Abstract Drift experiments are essential to understand stranding patterns and estimate the mortality of beached animals. Most studies do not use telemetry technology due to the high costs of this methodology. The objective of this paper is to describe the possibilities of tracking marine tetrapod carcasses with a low‐cost and replicable methodology ...

Mechanical energy on anaerobic capacity during a supramaximal treadmill running in men: Is there influence between runners and active individuals?

open access: yesPhysiological Reports, Volume 11, Issue 5, March 2023., 2023
Abstract This study verified whether mechanical variables influence the anaerobic capacity outcome on treadmill running and whether these likely influences were dependent of running experience. Seventeen physical active and 18 amateur runners, males, performed a graded exercise test and constant load exhaustive running efforts at 115% of intensity ...

The interplay between gastrocnemius medialis force–length and force–velocity potentials, cumulative EMG activity and energy cost at speeds above and below the walk to run transition speed

open access: yesExperimental Physiology, Volume 108, Issue 1, Page 90-102, 1 January 2023., 2023
Abstract The aim of this study was to investigate the interplay between the force–length (F–L) and force–velocity (F–V) potentials of gastrocnemius medialis (GM) muscle fascicles, the cumulative muscle activity per distance travelled (CMAPD) of the lower limb muscles (GM, vastus lateralis, biceps femori, tibialis anterior) and net energy cost (Cnet ...

Study on the population structure of the paradoxical frog, Pseudis bolbodactyla (Amphibia: Anura: Hylidae), using natural markings for individual identification

open access: yesZoologia (Curitiba), 2013
The goal of this study was to assess the population structure of Pseudis bolbodactyla Lutz, 1925 using natural markings to identify individuals. Recruitment, survival, and population size estimations were obtained using the Jolly-Seber stochastic method.
