Qualidade físico-química da água para irrigação do Rio Piancó Piranhas Açu na cidade de Pombal – PB

open access: yesRevista Verde de Agroecologia e Desenvolvimento Sustentável, 2014
A prática da irrigação, muitas vezes, é a única possibilidade de garantir a produção agrícola, especialmente em regiões tropicais de clima quente e seco, como é o do semiárido do Nordeste brasileiro.

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

open access: yesThe Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Adductor mandibulae muscle and lower jaw morphology: an approach to determine bite strategies in piranhas and relatives (Serrasalmidae, Characiformes, Teleostei)

open access: yes, 2017
Serrasalmidae (98 species) is a large monophyletic group of South American freshwater fishes. They have different dietary preferences ranging from the predominantly herbivorous or frugivorous pacus to the omnivorous or primarily carnivorous piranhas ...

Exploring the cranial morphology and possible convergences of Triassic non‐crocodylomorph pseudosuchians (Archosauria: Pseudosuchia) with other sauropsids through linear morphometrics

open access: yesThe Anatomical Record, EarlyView.
Abstract Triassic pseudosuchians had highly diversified cranial morphologies. These archosaurs occupied diverse ecological roles, ranging from terrestrial predators and herbivores to semiaquatic ambush predators and possible waders. Here, we apply linear cranial morphometrics to assess possible convergences with other sauropsids from the clades ...

The 9+ month marathon: How pregnancy may have shaped human endurance capacities

open access: yesThe Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

PIRANHAS: PrIvacy-Preserving Remote Attestation in Non-Hierarchical Asynchronous Swarms [PDF]

open access: yes
Remote attestation is a fundamental security mechanism for assessing the integrity of remote devices. In practice, widespread adoption of attestation schemes is hindered by a lack of public verifiability and the requirement for interaction in existing ...

Exceptional preservation informs the paleobiology of tapinocephalid dinocephalians

open access: yesThe Anatomical Record, EarlyView.
Abstract The tapinocephalid dinocephalian Moschops is one of the most iconic taxa of the middle Permian, yet its paleobiology remains one of the least well‐known. Here, we address some aspects of paleoneurology and paleobiology of Moschops using CT scanning of four well preserved skulls from the upper Abrahamskraal Formation of South Africa. Two of the
