Adaptation strategies of Icelandic horses with induced transient hindlimb lameness at walk, trot and tölt

Equine Veterinary Journal, EarlyView.
Abstract Background Icelandic horses are valued for their additional gaits, but assessing lameness in this breed can be challenging. Pelvic (P) vertical movement asymmetries, differences (D) in minimum (min)/maximum (max) position, are used to quantify impact (PDmin) and push‐off (PDmax) hindlimb lameness during the trot, but no established parameters ...

Fitosociología y sucesión en el volcán Paricutín (Michoacan, México)

Caldasia, 1997
A phytosociologic survey of the current vegetation covering the cone and lava flow of Paricutín Volcano was conducted 44 years after eruption. A cluster analysis of a total of 57 relevés was made using a two-way indicator species algorithm, Twinspan ...

Invasive insect colonisation shapes the population distribution of an island‐endemic scaly cricket

Insect Conservation and Diversity, EarlyView.
I assessed whether non‐native insect colonisation altered the population distribution of one case study island‐endemic insect: Discophallus ascension of volcanic Ascension Island in the South Atlantic. Invasive ants and crickets had strongly reduced D.

Study of Subsurface Structures Northwest of Ascraeus Mons, Mars, Based on Variational Bayesian Monte Carlo

IEEE Access
Tharsis Montes is the largest volcanic province on Mars, and Ascraeus Mons in its northeastern part is the largest volcano of the province. The material composition of the lava flows and lava plains to the northwest of Ascraeus Mons is important for the ...

Venusian sinuous rilles [PDF]

After a preliminary assessment of venusian channels, it now seems to be clear that the channels have distinctive classes, which imply a wide range of formation parameters and formation mechanisms. They include outflow channels mainly formed by mechanical

Strangeness content of the nucleon in quasielastic neutrino-nucleus reactions

, 2007
We present a systematic study of the sensitivity of quasielastic neutrino-nucleus cross sections at intermediate energies to the strange quark sea of the nucleon. To this end, we investigate the impact of the weak strangeness form factors on the ratio of

Historical Drainage Evolution and Water Level Fluctuations in the African Great Lakes Shaped Phylogeny and Biogeography of Freshwater Gastropods

Journal of Biogeography, EarlyView.
ABSTRACT Aim The role of historical drainage connectivity and the influence of water level fluctuations in African lakes on the evolution and distribution of macroinvertebrates remain poorly understood. This is partly because evolutionary biology research has largely focused on mobile vertebrates, such as cichlids.

Complex lava tube networks developed within the 1792–93 lava flow field on Mount Etna (Italy): insights for hazard assessment

Frontiers in Earth Science
Lava tubes are powerful heat insulators, allowing lava to practically keep the initial temperature and travel longer distances than when freely flowing on the ground surface.
