“…Moreover, this frog can extend its breeding season; meanwhile, the adult females can have oocytes of different maturity ages (Marisa Esteban et al, 1999). The other species, the Checkerboard Worm Lizard and Maghreb Garden Dormouse, are known to be highly adapted to the arid and semi-arid environment (Barata et al, 2011;López-García, Agustí, & Aouraghe, 2013). A previous paleontological study showed that the key mammals in the Mediterranean bioregion adapted to dry condition since the Holocene period which was slightly drier than today (López-García et al, 2013).…”

Aim Understanding diversity patterns and identifying the environmental factors that shape these patterns are essential for ecology and conservation. The Afro‐Arabian region comprises one of the most important biogeographic areas connecting continents. Yet, little emphasis has been put on understanding its endemic fauna in relation to its biogeographic realms. Our objective is to fill the gaps in knowledge on diversity patterns and biogeography that are essential for prioritizing the overdue conservation efforts. Location The study area covers mostly the hot desert climate region in North Africa and Arabia, and includes the Mediterranean, Sahel, and Ethiopian highlands (hereafter “Afro‐Arabian region”). Methods We used distribution maps developed by IUCN and BirdLife for species endemic to the Afro‐Arabian region belonging to the four tetrapod classes, amphibians, reptiles, birds, and mammals, to identify the endemic richness hotspots. We then used multivariate analyses to delineate biogeographic regions and evaluate their relationship with the environmental factors. Results Our study reveals a complex map of the richness hotspots for the endemic tetrapod classes. The main hotspots of endemism were concentrated at the margins of the study area, along the Mediterranean coast, Ethiopian highlands, and along the Red Sea Mountains. We propose classifying the Afro‐Arabian region into three discrete biogeographic realms for endemic amphibians, four for reptiles and birds, and five discrete biogeographic realms for endemic mammals. The identified realms are defined by their environmental conditions and the historical geological processes. Main conclusions Richness hotspots of endemic tetrapod classes were heterogeneously distributed in the Afro‐Arabian region. Our results support the hypothesis that species diversity patterns and endemism have been shaped by the environmental conditions and the paleogeographic processes. Each of the identified bioregions is associated with a characteristic set of tetrapod species. Our results are a benchmark for assessing the effectiveness of the protected areas and for implementing conservation plans for biodiversity.

“…The Middle to Late Pleistocene boundary is characterized by the extinction of numerous small mammal taxa, including all the fossil shrew species (Stoetzel, 2013). During the Late Pleistocene, most of the present Moroccan species were recorded from several Late Pleistocene and Holocene sites, such as Irhoud Neanderthal (Jaeger, 1970(Jaeger, , 1975Amani and Geraads, 1998), Oulad Hamida 2 (Felids cave; Raynal et al, 2008;Geraads et al, 2010), Chrafate (Ouabhi et al, 2003), Ez Zarka (Ouabhi et al, 2003), Guenfouda (Aouraghe et al, 2010;Lopez-García et al, 2013), and El Harhoura 2 (Stoetzel, 2009;Stoetzel et al, 2010Stoetzel et al, , 2011. In Morocco, the presence of crocidurines concerns mostly C. russula, C. whitakeri and to a lesser extent also C. tarfayensis.…”

“…Como consecuencia las asociaciones de roedores han sido tradicionalmente usadas en paleontología como indicadores paleoambientales (Daams & Meulen, 1984;Sesé, 1991Sesé, , 2011Meulen & Daams, 1992;Voglino & Pardiñas, 2005;Hernández Fernández, 2006). Las abundancias relativas de las diferentes especies constituyentes de las asociaciones de roedores registradas en los yacimientos se han usado para realizar inferencias paleocológicas desde hace déca-das (Weerd & Daams, 1978;Sesé, 1991;Meulen & Daams, 1992;Dam, 1997;Daams et al, 1999;Cuenca-Bescós et al, 2009;Anemone et al, 2012;Rodrigues et al, 2012;López-García et al, 2013;Fernández García, 2014;Lyman, 2014). Al hacer estas inferencias, se asume de manera implícita que hay una homogeneidad en la composición faunística dentro de un mismo nivel fosilífero.…”

Las asociaciones de roedores son utilizadas de manera generalizada en paleontología para realizar inferencias paleoambientales. En ocasiones, asumiendo una homogeneidad lateral en el contenido fosilífero de los niveles estratigráficos, estas inferencias se llevan a cabo utilizando las abundancias relativas de las distintas especies que componen esas asociaciones. No obstante, nunca se ha comprobado experimentalmente dicha homogeneidad espacial en las proporciones específicas dentro de un mismo nivel fosilífero. Para comprobar esta homogeneidad lateral, en este trabajo se compararon dos muestras procedentes del tramo T1 (Somosaguas- Sur y Cata-3) del yacimiento paleontológico de Somosaguas (Mioceno Medio), correspondientes a dos puntos de muestreo separados unos 30 m. Aunque se mantuvo una composición faunística idéntica desde un punto de vista cualitativo, los análisis realizados por medio de aleatorizaciones de Monte Carlo, indicaron la existencia de diferencias significativas en las abundancias relativas de las distintas especies entre las dos muestras. Estos resultados podrían deberse a 1) un diferente comportamiento sedimentario de las piezas dentales de las distintas especies debido a diferencias en su tamaño; 2) el reducido tamaño de las muestras de sedimento en combinación con la elevada densidad de restos fósiles en el tramo T1 de Somosaguas; 3) una mezcla temporal diferencial relacionada con la presencia de varios abanicos aluviales sucesivos, sumado a cambios poblacionales de la comunidad local de roedores influidos por cambios ambientales durante el Aragoniense. Nuestros resultados muestran la necesidad de ser cautelosos a la hora de realizar inferencias palecológicas basadas en abundancias relativas de especies de micromamíferos.
