Controlled landing requires preparation. Mammals and bipedal birds vary how they prepare for landing by predicting the timing and magnitude of impact from the integration of visual and non-visual information. Here we explore how an animal that moves primarily through hopping, Rhinella marina, the cane toad, integrates sensory information to modulate landing preparation. Earlier work suggests toads may modulate landing preparation using predictions of impact timing and/or magnitude based on non-visual sensory feedback during takeoff...
Data from: Making soil particle size analysis by laser diffraction compatible with standard soil texture determination methodsFelipe Montes, Giovani Stefani Faé, Ekaterina Bazilevskaya, Rodrigo Masip Añó & Armen Kemanian
The standard sieving, pipette and hydrometer methods for soil particle size analysis (PSA) have three main drawbacks: procedures are tedious, time-consuming, and the results are protocol-dependent. Laser diffraction PSA delivers rapid results using standardized procedures, but so far it has been difficult to reconcile results with those from standard sedimentation methods. The objective of this study was to develop a protocol that would permit direct usage of laser diffraction PSA and render results compatible with...
How coniferous forests evolved in the Northern Hemisphere remains largely unknown. Unlike most groups of organisms that generally follow a latitudinal diversity gradient, most conifer species in the Northern Hemisphere are distributed in mountainous areas at middle latitudes. It is of great interest to know whether the mid-latitude region has been an evolutionary cradle or museum for conifers and how evolutionary and ecological factors have driven their spatiotemporal evolution. Here, we investigated the macroevolution of...

A lack of optimal gene combinations, as well as low levels of genetic diversity are often associated with the formation of species range margins. Conservation efforts rely on predictive modelling using abiotic variables and assessments of genetic diversity to determine target species and populations for controlled breeding, germplasm conservation and assisted migration. Biotic factors such as interspecific competition and hybridization, however, are largely ignored, despite their prevalence across diverse taxa and their role as key...
Data from: Thermal physiology responds to interannual temperature shifts in a montane horned lizard, Phrynosoma orbiculareBrooke Bodensteiner, Saúl Domínguez-Guerrero, Fausto Méndez-De La Cruz, Martha Muñoz, Alexis Pardo-Ramírez & David Aguillón-Gutierrez
As climate change marches on, rapidly rising temperatures shatter records every year, presenting ever‐growing physiological challenges to organisms worldwide. Ectotherms rely on behavioral and physiological plasticity to contend with environmental fluctuations. Nonetheless, our understanding of thermal plasticity has been largely limited to laboratory settings. Here, we test whether aspects of thermal physiology respond to interannual shifts in thermal environment in a natural population of Phrynosoma orbiculare, a montane horned lizard, from Hidalgo, Mexico. At our...
Data from: In and out of refugia: historical patterns of diversity and demography in the North American Caesar’s mushroom species complexSantiago Sánchez-Ramirez, Rodham E. Tulloss, Laura Guzmán-Davalos, Joaquín Cifuentes-Blanco, Ricardo Valenzuela, Arturo Estrada-Torres, Felipe Ruán-Soto, Raúl Díaz-Moreno, Nallely Hernández-Rico, Mariano Torres-Gómez, Hugo León & Jean-Marc Moncalvo
Some of the effects of past climate dynamics on plant and animal diversity make-up have been relatively well studied, but to less extent in fungi. Pleistocene refugia are thought to harbor high biological diversity (i.e. phylogenetic lineages and genetic diversity), mainly as a product of increased reproductive isolation and allele conservation. In addition, high extinction rates and genetic erosion is expected in previously glaciated regions. Some of the consequences of past climate dynamics might involve...
Data from: The role of hybridization during ecological divergence of southwestern white pine (Pinus strobiformis) and limber pine (P. flexilis)Mitra Menon, Justin C. Bagley, Christopher J. Friedline, Amy V. Whipple, Anna W. Schoettle, Alejandro Lael-Saenz, Christian Wehenkel, Francisco Molina-Freaner, Lluvia Flores-Renteria, M. Socorro Gonzalez-Elizondo, Richard A. Sniezko, Samuel A. Cushman, Kristen M. Waring & Andrew J. Eckert
Interactions between extrinsic factors, such as disruptive selection, and intrinsic factors, such as genetic incompatibilities among loci, often contribute towards the maintenance of species boundaries. The relative roles of these factors in the establishment of reproductive isolation can be examined using species pairs characterized by gene flow throughout their divergence history. We investigated the process of speciation and the maintenance of species boundaries between Pinus strobiformis and P. flexilis. Utilizing ecological niche modeling, demographic modeling,...
