Early anthropogenic change in western Mediterranean mountains (Sierra Nevada, SE Spain)

“…The DC pollen diagram shows that the Betula populations were no larger than the current ones for the last 5000 years. Cedrus presence in several pollen diagrams of south-eastern Spain has long been attributed to the Saharian winds (Magri, 2012), mainly in arid periods (see details on J o u r n a l P r e -p r o o f Alba- Sánchez et al, 2018). However, its appearance in the present study and other works for the SN (Anderson et al, 2011;Jiménez-Moreno et al, 2013;Manzano et al, 2019) does not correspond (Fig.…”

The history of Abies pinsapo during the Holocene in southern Spain, based on pedoanthracological analysis

“…Alba-Sánchez and López-Sáez (2013) noted that pollen from Abies has been found in different parts of the Cordillera Bética from ponds, peat bogs or caves in Málaga, Granada, Almería, Jaén, Alicante, Valencia, Castellón and Gibraltar, and that this almost certainly belonged to A. pinsapo, the only fir that grows naturally in southern Spain, so raising the possibility that it was much more widely distributed in the past (Alba-Sánchez et al 2018). In the south of the Iberian Peninsula, there is a great deal of pollen-based evidence of Abies sp.…”

“…These limestone-peridotite areas in medium to high mountains (1,000-2,000 m) retain similar ecological characteristics to those which existed during the Würm glacial period lower down in the southernmost part of the Iberian Peninsula, which has enabled them to become biogeographical refuge areas for A. pinsapo. This has facilitated its survival there to the present day, while ensuring its genetic isolation and independent evolution from other European and North African firs in the Mediterranean basin (Jaramillo-Correa et al 2010;Alba-Sánchez et al 2018).…”

Paleoecología, analizando la cuarta dimensión de la biodiversidad

“…En este especial sobre paleoecología añadimos la cuarta dimensión, el tiempo, a temas fundamentales en ecología como lo son la relación entre temperatura y tamaño de los individuos (regla de Bergmann) (Martínez Monzón at al. 2018), la relación entre los cambios climáticos y la diversidad (Furió et al 2018), cómo interpretar los cambios bióticos en un contexto de cambio global (Pelegrin et al 2018), los efectos del impacto humano en los ecosistemas (Montoya 2018; Torres y Baena 2018) y en los rangos geográficos de especies relictas (Alba-Sánchez et al 2018), o la necesidad de replantearnos los métodos que utilizamos para testar nuestras hipótesis (Nieto-Lugilde et al 2018;Guevara et al 2018;Moreno-Amat 2017). Por último, recomendamos un libro con entrevistas a 22 paleontólogos como una buena manera de iniciarse en el mundo de la paleobiología (Pimiento 2018).…”
