Underlying Ossification Phenotype in a Murine Model of Metastatic Synovial Sarcoma (open access)

Underlying Ossification Phenotype in a Murine Model of Metastatic Synovial Sarcoma

This article presents the analysis of genetic mouse models of synovial sarcoma to determine the extent of ossification in the tumors and its relationship with morbidity. The authors noted higher ossification within their metastatic mouse model of synovial sarcoma. Their conclusion is that both metastasis and ossification are dependent on time, but that they are independent of one another.

The metabolic cost of turning right side up in the Mediterranean spur-thighed tortoise (Testudo graeca) (open access)

The metabolic cost of turning right side up in the Mediterranean spur-thighed tortoise (Testudo graeca)

Article examining the the metabolic cost of self-righting in the terrestrial Mediterranean spur-thighed tortoise using respirometry and kinematic video analysis and comparing this to the metabolic cost of locomotion at a moderate, easily sustainable speed. The results found that self-righting is, relatively, metabolically expensive and costs around two times the mass-specific power required to walk.

Evidence of Endozoochory in Upland Geese Chloephaga picta and White-Bellied Seedsnipes Attagis malouinus in Sub-Antarctic Chile (open access)

Evidence of Endozoochory in Upland Geese Chloephaga picta and White-Bellied Seedsnipes Attagis malouinus in Sub-Antarctic Chile

This article evaluates the role of endozoochory in herbivorous and sympatric bird species in sub-Antarctic Chile. The authors hypothesize that fragments of bryophyte gametophytes retrieved from their feces are viable and capable of regenerating new plant tissue. This relationship may have important implications in the way bryophytes disperse and colonize habitats facing climate change.
