Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

Integrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Impact of global change on the distribution of mountain mammals and birds

Conservation Biology, EarlyView.
Abstract Climate change and land‐use changes are key drivers of global biodiversity loss. Many species are shifting to higher elevations or latitudes in response to global warming, often encountering unfavorable land‐use conditions during the shift. These changes can lead to reduced range size and increased extinction risks, particularly for mountain ...

The Betic Cordillera: an active orogen [PDF]

, 2019
Desde un punto de vista sísmico y tectónico la Cordillera Bética constituye la parte más activa de la península Ibérica. Este orógeno es el resultado de la interacción entre dos placas mayores o principales (Nubia y Eurasia) y una mucho más pequeña, la ...

Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests

New Phytologist, EarlyView.
Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Características de la Araucanización al oriente de los Andes

Cultura-Hombre-Sociedad
Mapuche- Su etimlogía es muy conocida (araucano mapú "tierra"y che "gente", "gente de lo tierra"). Propongo que se lo utilice estrictamente con su sentido originario, es decir, para denominar al pueblo que pobló y puebla lo Araucanía propiamente dicha ...

Crustal structure of the central sector of the Betic Cordillera (SE Spain) [PDF]

Tectonics, 1997
Deep seismic reflection, gravimetric, and magnetometric data allow the main features of the deep structure of the central sector of the Betic Cordillera to be established. The Moho is horizontal or dips slightly toward the S below the mountain chain, and its morphology has no direct relationship with the region's topography. The deep reflectors are not

Elevation shapes alpine snow algal blooms and their influence on albedo reduction

New Phytologist, EarlyView.
Graphical summary of elevational trends in Sanguina‐dominated snow algal blooms. Increasing elevation was associated with larger cells, lower Chla content per cell, higher astaxanthin ratios, lower snow water content, and reduced cell‐normalized albedo, whereas algal cell density showed no consistent elevational trend.
