Ancient DNA reveals interstadials as a driver of common vole population dynamics during the last glacial period

Mateusz Baca, Danijela Popović, Anna Lemanik, Sandra Bañuls‐Cardona, more

Journal of Biogeography > 50 > 1 > 183 - 196

Aim Many species experienced population turnover and local extinction during the Late Pleistocene. In the case of megafauna, it remains challenging to disentangle climate change and the activities of Palaeolithic hunter‐gatherers as the main cause. In contrast, the impact of humans on rodent populations is likely to be negligible. This study investigated which climatic and/or environmental factors...

One million years of diversity shifts in amphibians and reptiles in a Mediterranean landscape: resilience rules the Quaternary

Almudena Martínez‐Monzón, Gloria Cuenca‐Bescós, Josep‐Francesc Bisbal‐Chinesta, Hugues‐Alexandre Blain, more

Palaeontology > 64 > 5 > 673 - 686

In contrast with the well documented strain on extant amphibian and reptile populations today, the Quaternary fossil record of these groups is very conservative showing few changes over long periods of time. In order to establish the non‐human‐induced effect of climate change on herpetofaunal diversity, we collected data from Pleistocene sites in the Sierra de Atapuerca complex (Burgos, Spain), which...

Structure and composition of the incisor enamel of extant and fossil mammals with tooth pigmentation

Raquel Moya‐Costa, Blanca Bauluz, Gloria Cuenca‐Bescós

Lethaia > 52 > 3 > 370 - 388

The inclusion of iron compounds in teeth, which impart a red to orange colour to them, is a phenomenon shown by several groups of vertebrates in different periods of their evolution. Incisors from fossil and extant shrews and from extant rodents were sectioned and studied with the techniques of scanning electron microscopy (SEM), transmission electron microscopy (TEM) and scanning transmission electron...

Climate and amphibian body size: a new perspective gained from the fossil record

Almudena Martínez‐Monzón, Hugues‐Alexandre Blain, Gloria Cuenca‐Bescós, Miguel Ángel Rodríguez

Ecography > 41 > 8 > 1307 - 1318

In recent years several studies have been carried out to test the validity of Bergmann's rule for amphibians, and have generated varying results. Due to the lack of agreement on this topic, here we examine the relationship between climate and body size for one anuran species (Bufo calamita, commonly known as the natterjack toad) with a new methodological approach that uses the fossil record as the...

Cranial Biometrics of the Iberian Myotis myotis/Myotis blythii Complex: New Data for Studying the Fossil Record

Julia Galán, Carmen Núñez-Lahuerta, Víctor Sauqué, Gloria Cuenca-Bescós, more

Journal of Mammalian Evolution > 2019 > 26 > 3 > 333-344

The Myotis myotis/M. blythii species complex, spread across the Western Palearctic, is a problematic group for which the taxonomy of the species is not yet satisfactorily resolved. The Iberian Peninsula played a key role in its evolutionary history as a Pleistocene refuge and as the starting point for the eastward expansion of M. myotis in the early Holocene, while M. blythii reached the Iberian Peninsula...

Lateglacial to Late Holocene palaeoclimatic and palaeoenvironmental reconstruction of El Mirador cave (Sierra de Atapuerca, Burgos, Spain) using the small-mammal assemblages

Sandra Bañuls-Cardona, Juan Manuel López-García, Juan Ignacio Morales Hidalgo, Gloria Cuenca-Bescós, more

Palaeogeography, Palaeoclimatology, Palaeoecology > 2017 > 471 > C > 71-81

El Mirador is a cave in the Sierra de Atapuerca (northern Iberian Peninsula) that contains 27 archaeological layers from the Lateglacial to the Late Holocene. A total of 4436 small-mammal remains have been analysed from these layers, and 19 taxa have been identified (three insectivores, seven chiropters and nine rodents). The palaeoenvironmental reconstruction based on a small-mammal analysis suggests...

Beavers (Castoridae, Rodentia, Mammalia) from the Quaternary sites of the Sierra de Atapuerca, in Burgos, Spain

Gloria Cuenca-Bescós, Jordi Rosell Ardévol, Álvaro Morcillo-Amo, María Ángeles Galindo-Pellicena, more

Quaternary International > 2017 > 433 > PA > 263-277

The Eurasian beaver, Castor fiber is known from the Pleistocene in Europe, although there are references to the presence of the genus Castor since the Miocene, ca. 10 Ma. Beavers are present in the Iberian Peninsula since the Pliocene, though the first appearance of Castor fiber took place in the Early Pleistocene levels of the localities of the Sierra de Atapuerca, where the fossil beaver remains...

First report on the birds (Aves) from level TE7 of Sima del Elefante (Early Pleistocene) of Atapuerca (Spain)

Carmen Núñez-Lahuerta, Gloria Cuenca-Bescós, Rosa Huguet

Quaternary International > 2016 > 421 > C > 12-22

The sites of the Sierra de Atapuerca (Burgos, Spain) are renowned for providing a complete Quaternary record, both archaeological and paleontological. The record consists of cave filling sediments in a karst system, developed in carbonate rocks. The Sima del Elefante site is divided into three units, in accordance with its geological features: the lower red unit (TELRU) (Early Pleistocene), the middle...

Morphometric approach to Titanosauriformes (Sauropoda, Dinosauria) femora: Implications to the paleobiogeographic analysis

José I. Canudo, Gloria Cuenca-Bescós

Morphometrics > 143-156

A morphometric approach to Titanosauriformes sauropod dinosaur femora provides an interesting tool for systematic and paleobiogeographic studies. The femur is an element of phylogenetic interest, being the proximal one third deflected medially or lateral bulge one of the autapomorphies of Titanosauriformes. Some of the selected 20 landmarks use to be reference anatomical points for the femur measurements,...

Biostratigraphy, palaeogeography and palaeoenvironmental significance of Sorex runtonensis Hinton, 1911 (Mammalia, Soricidae): First record from the Iberian Peninsula

Juan Rofes, Raquel Moya-Costa, Maria Bennàsar, Hugues-Alexandre Blain, more

Palaeogeography, Palaeoclimatology, Palaeoecology > 2016 > 459 > C > 508-517

Sorex runtonensis (Mammalia, Soricidae) is a well-known Pleistocene taxon with a broad distribution in Europe. However, no record of the species had been reported from the Iberian Peninsula up to now. Here we present nearly two hundred specimens of S. runtonensis recovered from the Lower Red Unit (levels TE7–14) of Sima del Elefante (Sierra de Atapuerca, Burgos, Spain), dated to ~1.1–1.5Ma. Rigorous...

Julia Galán, Gloria Cuenca-Bescós, Juan Manuel López-García

Comptes Rendus Palevol > 2016 > 15 > 6 > 647-657

The fossil bat assemblage from the Lower Red Unit of Sima del Elefante (TELRU) in Atapuerca (Burgos, Spain) has been exhaustively analysed for the first time. Bat fossil assemblages are of particular relevance to palaeoenvironmental approaches to sites. Here we integrate our new data on the chiropteran fauna with the data provided previously by other authors on the basis of the small-vertebrate assemblages...

Paleoecological and microenvironmental aspects of the first European hominids inferred from the taphonomy of small mammals (Sima del Elefante, Sierra de Atapuerca, Spain)

Maria Bennàsar, Isabel Cáceres, Gloria Cuenca-Bescós

Comptes Rendus Palevol > 2016 > 15 > 6 > 635-646

Unit TE9 of the Sima del Elefante (Sierra de Atapuerca, Burgos, Spain), where the remains of Homo sp. have been discovered (1.2–1.3Ma), is also a level rich in small mammals. The taphonomic study of these small vertebrates sheds light on the landscape that provided the setting for the activities of these early hominids and allows us to describe what the cave was like during the formation of the level...

Fossil bats from the Late Pleistocene site of the Aguilón P7 Cave (Zaragoza, Spain)

Julia Galán, Gloria Cuenca-Bescós, Juan Manuel López-García, Víctor Sauqué, more

Comptes Rendus Palevol > 2016 > 15 > 5 > 501-514

Bats (Chiroptera, Mammalia) are a valuable and independent source of palaeoenvironmental information in Quaternary sites because bat assemblages are not necessarily produced by the same processes as those of other small mammals. Here, we report a small collection of bats (MNI 15) from a cave infill of the Aguilón P7 (AGP-7) site (Zaragoza, Spain) dated Late Pleistocene (MIS 3). This is one of the...

Comparing two different Early Pleistocene microfaunal sequences from the caves of Atapuerca, Sima del Elefante and Gran Dolina (Spain): Biochronological implications and significance of the Jaramillo subchron

Gloria Cuenca-Bescós, Hugues-Alexandre Blain, Juan Rofes, Iván Lozano-Fernández, more

Quaternary International > 2015 > 389 > C > 148-158

No ideal method can be used alone to provide an accurate and irrefutable chronology for dating European Early Pleistocene localities. The solution lies in the combination of different, but complementary, approaches for complementing their chronological framework. In that regard, the results of the present study show that biochronology may be a useful additional tool to further refine the chronology...

The vegetational and climatic contexts of the Lower Magdalenian human burial in El Mirón Cave (Cantabria, Spain): implications related to human behavior

María-José Iriarte-Chiapusso, Alvaro Arrizabalaga, Gloria Cuenca-Bescós

Journal of Archaeological Science > 2015 > 60 > Complete > 66-74

This paper presents and discusses the results of the studies of pollen and micro-mammal remains associated with the human burial in El Mirón Cave, dated in the Lower Magdalenian. The sedimentological integrity of the deposit has been confirmed through its comparison with the penecontemporaneous level in other parts of the cave. From the environmental point of view, this unit, like others of the same...

Biochronological data inferred from the Early Pleistocene small mammals of the Barranc de la Boella site (Tarragona, north‐eastern Spain)

IVÁN LOZANO‐FERNÁNDEZ, SANDRA BAÑULS‐CARDONA, HUGUES‐ALEXANDRE BLAIN, JUAN MANUEL LÓPEZ‐GARCÍA, more

Journal of Quaternary Science > 29 > 7 > 722 - 728

In 2007, remains of Mammuthus meridionalis and 334 lithic artefacts were recovered in level 2 of Barranc de la Boella. The presence of M. meridionalis allows us to assign an age older than 700 ka to this level, which represents one of the few sites of this age with palaeontological remains associated with lithic industry. It also enables us to shed light on questions pertaining to the chronology and...

Human occupation of Iberia prior to the Jaramillo magnetochron (>1.07 Myr)

Joan Garcia, Kenneth Martínez, Gloria Cuenca-Bescós, Eudald Carbonell

Quaternary Science Reviews > 2014 > 98 > Complete > 84-99

The first migration out of Africa undertaken by the genus Homo is documented in Georgia at 1.8 Myr (Dmanisi) and some 0.4 Myr afterwards in the Middle East (’Ubeidiya). However, the debate on when the European continent was populated for the first time remains open. The first human presence in Europe prior to the Jaramillo subchron (1.07–0.99 Myr) is evidenced at Fuente Nueva 3 and Barranco León D...

Mimomys savini size evolution in the Early Pleistocene of south-western Europe and possible biochronological implications

Iván Lozano-Fernández, Gloria Cuenca-Bescós, Hugues-Alexandre Blain, Juan Manuel López-García, more

Quaternary Science Reviews > 2013 > 76 > Complete > 96-101

Over the course of their evolutionary history, some species of mammals have undergone variations in size, with a general trend towards increased morphometry. This effect can be seen very clearly in the fossil record of rodents because their high rate of reproduction that generates a high fossil record, which allows this phenomenon to be studied in detail. Furthermore, the rapid geographic distribution...
