MASTREE+: Time-series of plant reproductive effort from six continents. [PDF]

open access: yesGlob Chang Biol, 2022
MASTREE+ is an open‐access data set that collates reproductive time‐series data from across the globe. It includes 73,828 georeferenced observations of annual reproduction (e.g. seed and fruit counts) in perennial plant populations, consisting of 5,971 population‐level time‐series from 974 species.

Unraveling Biogeographic Boundaries Within the Sierra Madre Oriental, México: An Endemicity Analysis Using a Taxonomically Diverse Dataset. [PDF]

open access: yesEcol Evol
We provide boundaries of the Sierra Madre Oriental in Mexico through a multi‐taxa endemicity analysis. ABSTRACT The Sierra Madre Oriental (SMO) is a significant mountain range and one of Mexico's 14 biogeographical provinces. Its delimitation has been debated.

Anomalous latitudinal gradients in parasitoid wasp diversity-Hotspots in regions with larger temperature range. [PDF]

open access: yesJ Anim Ecol
Using the largest georeferenced molecular dataset for ichneumonoid parasitoid wasps, we implemented a macrogenetics approach to examine latitudinal patterns and predictors of intraspecific genetic diversity and explain the global distribution of genetic diversity in this group.

Repeated asynchronous evolution of single‐species endemics of ivies (Hedera L.) in Macaronesian archipelagos

open access: yesJournal of Biogeography, Volume 50, Issue 10, Page 1763-1777, October 2023., 2023
Abstract Aim Evolutionary studies of oceanic island endemics are usually focused on lineages that have experienced in situ radiation, while those that speciated once on the island or archipelago but have not further diversified (single‐species endemics) remain understudied.

Modelado geoestadístico de fertilidad de un terreno agrícola mediante mapas de Kriging que interpolan los datos de análisis químico de suelos

open access: yesProducción Agropecuaria y Desarrollo Sostenible, 2021
Dado que la fertilidad del suelo puede variar grandemente en distancias relativamente cortas, el método estadístico clásico no es adecuado para analizar los datos provenientes de análisis químicos de suelos.

Estimating species relative abundances from museum records

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 2, Page 431-443, February 2023., 2023
Abstract Dated, geo‐referenced museum specimens are a rich data source for reconstructing species' distribution and abundance patterns. However, museum records are potentially biased towards over‐representation of rare species, and it is unclear whether museum records can be used to estimate relative abundance in the field.

Regional economic disparities, spatial dependence and proximity structures

open access: yesRegional Science Policy &Practice, Volume 14, Issue 5, Page 1034-1050, October 2022., 2022
Abstract Since some decades, inequality has been attracting a growing interest within political debate as well as in theoretical and empirical studies. Considering inequality at a regional level offers useful insights for policy makers, facilitating the assessment of the effectiveness of strategies aimed at reducing regional disparities and helping in ...

Deflection of Vertical Effect on Direct Georeferencing in Aerial Mobile Mapping Systems: A Case Study in Sweden

open access: yesThe Photogrammetric Record, Volume 37, Issue 179, Page 285-305, September 2022., 2022
This paper aims to study and quantify the induced error due to the deflection of verticals (DOV) when integrating different sensors, focusing on GNSS and INS for 3D mapping in airborne mapping. It is shown that the DOV effect should be considered for direct georeferencing because the DOV components are in the order of (or larger than) INS uncertainty ...
