Efecto de diferentes tipos de enraizadores in vitro y sustratos en la aclimatación de Zigopetalum maculatum (Orchidaceae) [PDF]

Revista de Investigación e Innovación Agropecuaria y de Recursos Naturales
Las orquídeas tienen un gran potencial, pero, requieren medios de cultivo especializados para ser propagadas, ya que de manera natural menos de 5 % llegan a germinar y necesitan asociarse con hongos simbióticos. En ese sentido, el presente trabajo tiene

Evolutionary and environmental determinants of heat tolerance and acclimation capacity in herpetofauna. [PDF]

Conserv Biol
Abstract Exploring heat tolerance and acclimation capacity can provide an effective approach to evaluating species’ sensitivity to extremely high temperatures due to climate warming. Despite some work on amphibian and reptile thermophysiological adaptation, related questions remain. We reviewed the literature to provide a synthesis of worldwide data on

Elevation shapes alpine snow algal blooms and their influence on albedo reduction. [PDF]

New Phytol
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.

Efficient but Elusive Rhizobia Fix Nitrogen in the Wild Legumes Bituminaria bituminosa and Coronilla Viminalis. [PDF]

J Basic Microbiol
ABSTRACT In ecological restoration of degraded natural habitats, revegetation with wild native plants is a priority. Legumes play a key role in this process through nitrogen (N)‐fixing symbiosis with rhizobia, obtaining N for their growth and improving soil fertility, which benefits other nonleguminous plants in the environment. This study explores the

Evolutionary Changes in Crassulacean Acid Metabolism (CAM) and Related Traits During the Diversification of <i>Aichryson</i> (Crassulaceae) on the Macaronesian Islands. [PDF]

Ecol Evol
We explore evolutionary changes in Crassulacean acid metabolism (CAM) and associated traits during the diversification of Aichryson (Crassulaceae) across the Macaronesian Islands. By combining field data, physiological measurements and phylogenetic analysis, we identify shifts in photosynthetic strategy linked to habitat transitions.

Parallel evolution of arborescent carrots (Daucus) in Macaronesia. [PDF]

Am J Bot, 2020
Premise Despite intensive research, the pathways and driving forces behind the evolution of derived woodiness on oceanic islands remain obscure. The genus Daucus comprises mostly herbs (therophytes, hemicryptophytes) with few rosette treelets (chamaephytes) endemic to various Macaronesian archipelagos, suggesting their independent evolution.

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle. [PDF]

Conserv Biol
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We
