Wind effects on the migration routes of trans-Saharan soaring raptors: geographical, seasonal, and interspecific variation
2016
Wind is among the most important environmental factors shaping birds’ migration patterns. Birds must deal with the displacement caused by crosswinds and their behavior can vary according to different factors such as flight mode, migratory season, experience, and distance to goal areas. Here we analyze the relationship between wind and migratory movements of three raptor species which migrate by soaring–gliding flight: Egyptian vulture Neophron percnopterus, booted eagle Aquila pennata, and short-toed snake eagle Circaetus gallicus. We analyzed daily migratory segments (i.e., the path joining consecutive roosting locations) using data recorded by GPS satellite telemetry. Daily movements of E…
Data from: Moving in the Anthropocene: global reductions in terrestrial mammalian movements
2019
Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of the anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database of 803 individuals across 57 species, we found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in areas with a low human footprint. We attribute this reduction to behavioral changes of individual animals and to the exclusion of species with long-range movements from areas with higher human impact. Global loss of vagility alters a key ecological trait of animals that affects no…
Architectural Ultrasound Pennation Angle Measurement of Lumbar Multifidus Muscles: A Reliability Study
2022
The pennation angle has been shown to be a relevant parameter of muscle architecture. This parameter has not previously been measured in the lumbar multifidus musculature, and it is for this reason that it has been considered of great interest to establish an assessment protocol to generate new lines of research in the future. Objective: The objective of this study was to establish a protocol for measuring the pennation angle of the multifidus muscles, with a study of intra-rater and interrater reliability values. Design: This was a reliability study following the recommendations of the Guidelines for Reporting Reliability and Agreement Studies (GRRAS). Setting: The study was carried out at…

Antinociceptive and anti-inflammatory activities of Acacia pennata wild (Mimosaceae)
2005
The butanolic fraction of dried leaves of Acacia pennata (Mimosaceae) was tested for analgesic and anti-inflammatory activities in animal models. It showed significant protective effects against chemical stimuli (acetic acid and formalin) in the mouse. It also produced a significant increase of the threshold of sensitivity to pressure-induced pain in the rats. The extract revealed an inhibitory effect in carrageenin-induced rat paw oedema in the late phase. The results suggested that a peripheral mechanism is involved in the analgesic, associated to anti-inflammatory effect (NSAIDs-like). Among the class of compounds characterized in this fraction, flavonoids may be mainly responsible for t…
Mediterranean Paths The Construction of Vaults in Southern Italy, Sicily and Sardinia (15th–16th Centuries)
2019
Nel meridione della penisola italiana e nelle grandi isole, la costruzione delle volte nel XV e nel XVI secolo è stata caratterizzata da una peculiare coesistenza di continuità e innovazione. Le volte costruite in questo ampio territorio nei secoli in questione si possono suddividere in due grandi categorie di artefatti, che rispondono a criteri costruttivi, formali e geometrici differenti: le crociere con costoloni e i padiglioni di varia geometria. In questo ricco e variegato panorama, il saggio si sofferma ad analizzare alcune soluzioni di dettaglio e singoli elementi di strutture più articolate, che restituiscono tuttavia appieno il complesso intreccio di modelli e abilità tecniche, di …
