Temperature niche composition change inside and outside protected areas under climate warming

Conservation Biology, Volume 37, Issue 5, October 2023., 2023
Abstract Conservation of biodiversity relies heavily on protected areas but their role and effectiveness under a warming climate is still debated. We estimated the climate‐driven changes in the temperature niche compositions of bird communities inside and outside protected areas in southern Canada.

Spatial mobility patterns and COVID‐19 incidence: A regional analysis of the second wave in the Netherlands

Regional Science Policy &Practice, Volume 14, Issue S1, Page 21-40, November 2022., 2022
Abstract A key policy measure introduced by governments worldwide at the beginning of the coronavirus disease 2019 (COVID‐19) pandemic was to restrict travel, highlighting the importance of people's mobility as one of the key contributors to spreading severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2).

River connectivity and climate behind the long‐term evolution of tropical American floodplain lakes

Ecology and Evolution, Volume 11, Issue 19, Page 12970-12988, October 2021., 2021
We present a multi‐proxy approach on short sedimentary cores form two neotropical flood plain lakes associated with the Magdalena River, Colombia, to study temporal variation in diatoms, sediment geochemistry and climate. We proposed that lake hydrological connectivity to the Magdalena River is a main factor controlling lake long‐term responses to ...

Optimal timing for surgical reconstruction of bile duct injury: meta‐analysis

BJS Open, Volume 4, Issue 5, Page 776-786, October 2020., 2020
This meta‐analysis addressed the timing of surgical reconstruction with hepaticojejunostomy for bile duct injury. Reconstruction between 2 and 6 weeks after injury was associated with an increased risk of postoperative morbidity as well as anastomotic stricture formation.

Estimación de los parámetros del modelo no lineal de promedios móviles usando la metaheuristica de-PSO.

Revista Ingenierías Universidad de Medellín, 2014
La extensión teórica de los modelos lineales de promedios móviles al caso no lineal es directa y sencilla. Sin embargo, el uso práctico de los modelos no lineales de promedios móviles es limitado debido a la complejidad del espacio de parámetros y la ...

Complex and nonlinear climate‐driven changes in freshwater insect communities over 42 years

Conservation Biology, Volume 34, Issue 5, Page 1241-1251, October 2020., 2020
Abstract The ongoing biodiversity crisis becomes evident in the widely observed decline in abundance and diversity of species, profound changes in community structure, and shifts in species’ phenology. Insects are among the most affected groups, with documented decreases in abundance up to 76% in the last 25–30 years in some terrestrial ecosystems ...

Characterization of ground motions using recurrence plots

Geofísica Internacional, 2013
Los modelos matemáticos tradicionales relacionados con el análisis de los terremotos son lineales y en algunos casos son incapaces de predecir determinados comportamientos, porque los datos que modelan pueden ser altamente no lineales y complejos.
