Lamellar fluctuations melt ferroelectricity
(2023)We consider a standard Ginzburg-Landau model of a ferroelectric whose electrical polarization is coupled to gradients of elastic strain [1–4]. At the harmonic level, such flexoelectric interaction is known to hybridize ... -
Landau theory and giant room-temperature barocaloric effect
(2017-10-17)The structural phase transitions of MF3 (M = Al, Cr, V, Fe, Ti, Sc) metal trifluorides are studied within a simple Landau theory consisting of tilts of rigid MF6 octahedra associated with soft antiferrodistortive optic ... -
Landing manoeuvres predict roost-site preferences in bats
(2022-11-11)Roosts are vital for the survival of many species, and how individuals choose one site over another is affected by various factors. In bats, for example, species may use stiff roosts such as caves or compliant ones such ... -
Landslide Potential in Santo Domingo De Heredia, Costa Rica, Central America
(2014-10)This paper reports results from a survey of landslide potential in the canton (county) of Santo Domingo de Heredia, Costa Rica. This canton, like much of Central America, is located in a tropical region with abrupt topography ... -
Landslide risk index map at the municipal scale for Costa Rica
(2021-04-01)Landslides are a common natural hazard worldwide with greater socioeconomic impacts in developing and tropical countries. In Central America and Costa Rica, this phenomenon is mainly triggered by seismicity and extraordinary ... -
Lankester Botanical Garden: Fifty years spent with enthusiasm
(2023-11)The preservation of the Lankester Garden in Costa Rica is the greatest conservation effort made by those who love orchids. -
Lankester-Garten, der Botanische Garten in Cartago, Costa Rica
(2002)The Lankester Botanical Garden of the University of Costa Rica was founded in 1973, it was named in honor of the English natural scientist and previous owner Charles H. Lankester (1879-1969). This garden is internationally ... -
Lankesteriana a no impact journal... or is it?
(Universidad de Costa Rica, 2016)The word impact comes from the Latin impactus, to push against. It is defined by the Merriam-Webster dictionary as, among others, “to have a direct effect on”. In the realm of scientific publishing, impact is measured in ... -
Lankesteriana, a new genus in the Pleurothallidinae (Orchidaceae)
(Universidad de Costa Rica, 2014)We estimated phylogenetic relationships within Anathallis and related genera using Bayesian analyses of nrITS sequence data. The genus is biphyletic in the molecular trees. A novel generic concept, Lankesteriana, is proposed ... -
Large isotropic negative thermal expansion above a structural quantum phase transition
(2015-10-01)Perovskite structured materials contain myriad tunable ordered phases of electronic and magnetic origin with proven technological importance and strong promise for a variety of energy solutions. An always-contributing ... -
Large-scale climatic phenomena drive fluctuations in macroinvertebrate assemblages in lowland tropical streams, Costa Rica: The importance of ENSO events in determining long-term (15y) patterns
(2019-02-08)Understanding how environmental variables influence the distribution and density of organisms over relatively long temporal scales is a central question in ecology given increased climatic variability (e.g., precipitation, ... -
Larval aggression is independent of food limitation in nurseries of a poison frog
(2016)Aggression between nurserymates is common in animals and often hypothesized to result from proximate resource limita- tion. In numerous terrestrial frogs, larvae develop in phytotelmata, tiny water bodies where resources ...
