Lateglacial and Holocene glacier variations in an active volcanic area, northern Jan Mayen (Nord‐Jan), Norway

open access: yesBoreas, EarlyView.
Glacier evolution and environmental changes in the northern Jan‐Mayen from the early deglaciation and well into the Holocene are discussed. Results are based on a large chronological dataset (TCN and radiocarbon dates), integrated with field data on glacial landforms and sediments, including the use of GPR.

Lunar and Hawaiian lava tubes: Analogs and uses based on terrestrial field data [PDF]

open access: yes
Presented here is an analysis of the data collected for a large number of Hawaiian lava tubes on the islands of Oahu, Molokai, and Hawaii. The results are extrapolated to lunar conditions.

Talking to Strangers About Science: Youth Facilitators and Family Learning at the Natural History Museum

open access: yesCurator: The Museum Journal, EarlyView.
ABSTRACT Dioramas are an iconic part of natural history museums that present complex scientific content in a naturalistic scenic setting. Museums have struggled with how best to help visitors view and engage in learning at these exhibits. Recognizing the importance of human facilitation around these exhibits, we conducted a study to explore ...

Venusian sinuous rilles [PDF]

open access: yes
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

Erosion versus construction: The origin of Venusian channels [PDF]

open access: yes
Lava channels are a common feature in the volcanic regions of the Moon, and have now been observed on Venus. There has been much debate about the origin of lunar channels as to whether they are the result of erosional (either thermal or mechanical) or ...

Impact of lens distrortions on strain measurements obtained with digital image correlation [PDF]

open access: yes, 2012
The determination of strain fields based on displacements obtained via DIC at the micro-strain level is still a cumbersome task. In particular when high-strain gradients are involved, e.g. in composite materials with multidirectional fibre reinforcement,

Territory Size but Not Territorial Defence Varies With Habitat Quality and Competitor Density in a Farming Species

open access: yesEthology, EarlyView.
Algal‐farming damselfish in high‐quality habitats with more neighbours and smaller territories did not differ in their defence costs to those in poorer habitats with larger territories and fewer neighbours. While overall intrusion and attack frequencies were similar between these two habitat areas, territory holders interacted differently with ...

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

open access: yesEquine 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 ...

The 1984 Mauna Loa eruption and planetary geolgoy [PDF]

open access: yes
In planetary geology, lava flows on the Moon and Mars are commonly treated as relatively simple systems. Some of the complexities of actual lava flows are illustrated using the main flow system of the 1984 Mauna Loa eruption. The outline, brief narrative,
