About the #fossilrecord, its #biogeographical and #biological interpretations and current #research on the #brainmorphology of the #sabertoothedcat #Megatereon #cultridens.
The extinct tigers of the genus Megatereon (#Machairodontinae, #Felidae) likely evolved in late #Miocene #Africa and spread from there to Europe, Asia, and North America. The American saber-toothed tiger #Smilodon apparently descended from them.
Several #species of Megatereon are distinguished based on their fossil remains, of which M. cultridens was the most widespread, especially in #Europe. These animals were about the size of a modern jaguar and could reach a weight of 90 to 150 kg. The #forelimbs were more powerful than the hindlimbs, resulting in a slightly sloping #topline. The most characteristic feature was the conspicuously elongated upper #canineteeth.
The authors I. Meli et al. (2026) analyzed the precise brain morphology of M. cultridens and reconstructed that it had adaptations to a #generalist #lifestyle. Based on the enlarged #cerebellum, researchers assume that the species was a good #climber, albeit with comparatively poor #hearing, but possessed excellent #eyesight. The precise #neuroanatomical #study was conducted using endocasts obtained via #computertomography from the #skulls of three specimens found in #France, #Spain, and #Italy. The reconstruction of the individual brain structures and their relative dimensions was carried out using qualitative morphological studies as well as three-dimensional geometric #morphometry.
The results suggest that this was a species characterized by ecological versatility within its early #Pleistocene European #ecosystems.

A study led by the @NOCnews has revealed the existence of a #biogeographical boundary at the bottom of the North Pacific Ocean, resembling the ‘Wallace Line’ discovered in 1859 that divides the life of Asia and Oceania seabeds. More:

Freshwater invasions pose a global #conservation threat, but #biogeographical analyses can aid in effective management. A new method proposes an environmental resistance model for stream ecosystems, revealing insights for invasive species research.

We still know so little about the amazing #SeasonallyDryForest #biome! What #biogeographical implications has the description of this new #Euphorbiaceae from #Peru? 2 #species in the genus (🇧🇷&🇵🇪) separated by 4000km. Crazy! #DRYFLOR @toby_pennington @RicardaRiina @dneves_ecology
First collected 40 years ago but only now described as a #newspecies, Bahiana occidentalis becomes the second species in the previously #monotypic genus. It is #endemic to the seasonally dry #tropicalforests (SDTFs) of Peru: https://t.co/iz7ISz3krc

Ants …..a significant component of #biodiversity. Ever wondered about the global distribution of biomass of ants? I have. A really cool paper in PNAS begin to reveal #biogeographical patterns. Love such papers😀 https://t.co/ruILarlzzx
At a national level we have investigated 48 landscapes across Sweden in different #biogeographical zones. Landscape change analyses show that there is very little grassland left. Ancient grasslands are crucial and landscape #heterogeneity @LIMbioindikator unpublished work 8/n
