Item Body-size structure of Central Iberian mammal fauna reveals semidesertic conditions during the middle Miocene Global Cooling Event(PLoS ONE, 2017) Menéndez González, Iris; Blanco, Fernando; Domingo, Laura; Hernández Fernández, Manuel; Domingo Martínez, María Soledad; García Yelo, Blanca A.; Gómez Cano, Ana R.; Cantalapiedra, Juan L.We developed new quantitative palaeoclimatic inference models based on the body-size structure of mammal faunas from the Old World tropics and applied them to the Somosaguas fossil site (middle Miocene, central Iberian Peninsula). Twenty-six mammal species have been described at this site, including proboscideans, ungulates, carnivores, insectivores, lagomorphs and rodents. Our analyses were based on multivariate and bivariate regression models correlating climatic data and body-size structure of 63 modern mammal assemblages from Sub-Saharan Africa and the Indian subcontinent. The results showed an average temperature of the coldest month higher than 26ÊC for the Somosaguas fossil site, a mean annual thermal amplitude around 10ÊC, a drought length of 10 months, and an annual total precipitation greater than 200 mm per year, which are climate conditions typical of an ecotonal zone between the savanna and desert biomes. These results are congruent with the aridity peaks described over the middle Aragonian of Spain and particularly in the local biozone E, which includes Somosaguas. The aridity increase detected in this biozone is associated with the Middle Miocene Global Cooling Event. The environment of Somosaguas around 14 Ma was similar to the current environment in the Sahel region of North Africa, the Horn of Africa, the boundary area between the Kalahari and the Namib in Southern Africa, south-central Arabia, or eastern Pakistan and northwestern India. The distribution of modern vegetation in these regions follows a complex mosaic of plant communities, dominated by scattered xerophilous shrublands, semidesert grasslands, and vegetation linked to seasonal watercourses and ponds.Item Differential responses of Miocene rodent metacommunities to global climatic changes were mediated by environmental context(Scientific Reports, 2018) Blanco, Fernando; Gómez Cano, Ana Rosa; Cantalapiedra, Juan L.; Domingo Martínez, María Soledad; Domingo, Laura; Menéndez González, Iris; Flynn, Lawrence J.; Hernández Fernández, ManuelThe study of how long-term changes affect metacommunities is a relevant topic, that involves the evaluation of connections among biological assemblages across different spatio-temporal scales, in order to fully understand links between global changes and macroevolutionary patterns. We applied multivariate statistical analyses and diversity tests using a large data matrix of rodent fossil sites in order to analyse long-term faunal changes. Late Miocene rodent faunas from southwestern Europe were classified into metacommunities, presumably sharing ecological affinities, which followed temporal and environmental non-random assembly and disassembly patterns. Metacommunity dynamics of these faunas were driven by environmental changes associated with temperature variability, but there was also some influence from the aridity shifts described for this region during the late Miocene. Additionally, while variations in the structure of rodent assemblages were directly influenced by global climatic changes in the southern province, the northern sites showed a pattern of climatic influence mediated by diversity-dependent processes.Item Punctuated ecological equilibrium in mammal communities over evolutionary time scales(Science, 2021) Blanco, Fernando; Calatayud, Joaquín; Martín Perea, David Manuel; Domingo Martínez, María Soledad; Menéndez González, Iris; Müller, Johannes; Hernández Fernández, Manuel; Cantalapiedra, Juan L.The study of deep-time ecological dynamics has the ability to inform conservation decisions by anticipating the behavior of ecosystems millions of years into the future. Using network analysis and an exceptional fossil dataset spanning the past 21 million years, we show that mammalian ecological assemblages undergo long periods of functional stasis, notwithstanding high taxonomic volatility due to dispersal, speciation, and extinction. Higher functional richness and diversity promoted the persistence of functional faunas despite species extinction risk being indistinguishable among these different faunas. These findings, and the large mismatch between functional and taxonomic successions, indicate that although safeguarding functional diversity may or may not minimize species losses, it would certainly enhance the persistence of ecosystem functioning in the face of future disturbances.Item Macroevolution and climate changes: a global multi-family test supports the resource-use hypothesis in terrestrial mammals(Historical Biology, 2022) Hernández Fernández, Manuel; Pelegrin Ramírez, Jonathan S.; Gómez Cano, Ana Rosa; García Yelo, Blanca A.; Moreno Bofarull, Ana; Sánchez Fontela, Noelia; Rodríguez Ruiz, Claudia; Ramiro Camacho, Alejandro; Domingo Martínez, Laura; Menéndez González, Iris; Martín Perea, David Manuel; Bazán, Carla M.; Alcalde Rincón, Gema María; Domingo Martínez, María Soledad; Luna, Belén; Peinado Cortés, María del Mar; Arias Royo, Antón; González Couturier, Gabriela; Márquez Villena, Ana; Anaya, Noelia; Blanco, Fernando; Galli, Anna Emilia; Gamboa, Sara; Quesada García, Álvaro; Sanz Pérez, Danae; Varela, Sara; Cantalapiedra, Juan L.Elisabeth S. Vrba’s resource-use hypothesis suggests that speciation in biomes subjected to successive expansion-contraction-fragmentation during periods of climatic change generates high frequency of species restricted to a single biome (stenobiomic species). We compiled biome occupation for all terrestrial mammals and, using Monte Carlo simulations, demonstrated that patterns of biome occupation are congruent with those predicted by the resource-use hypothesis. Biome specialists are much more speciose than expected by chance, while there are fewer moderate biome generalists than expected. Despite their scarcity, extreme eurybiomic lineages show significant overrepresentation, which suggests they are seldom affected by climate-related extinction processes. Additionally, stenobiomic species are concentrated in biomes placed at the extremes of the climatic gradient, such as equatorial rainforest, subtropical desert, steppe, and tundra. Although this pattern is fairly maintained across different mammalian families, highlighting its universality, our analysis also found great variability. Exceptions to the predictions of the resource-use hypothesis seem to be associated to biome climatic or geographical heterogeneity, which favours vicariance in some biomes not placed in extremes of the climatic gradient (tropical deciduous woodland, sclerophyllous woodland-shrubland), as well as life-history differences across taxa, which generates a stronger trend to specialisation in small body size lineages than in larger mammals.Item The reorganization of predator–prey networks over 20 million years explains extinction patterns of mammalian carnivores(Ecology Letters, 2024) Nascimento, João C. S.; Blanco, Fernando; Domingo Martínez, María Soledad; Cantalapiedra, Juan L.; Pires,Mathias M.Linking the species interactions occurring at the scale of local communities to their potential impact at evolutionary timescales is challenging. Here, we used the high-resolution fossil record of mammals from the Iberian Peninsula to reconstruct a timeseries of trophic networks spanning more than 20 million years and asked whether predator–prey interactions affected regional extinction patterns. We found that, despite small changes in species richness, trophic networks showed long-term trends, gradually losing interactions and becoming sparser towards the present. This restructuring of the ecological networks was driven by the loss of medium-sized herbivores, which reduced prey availability for predators. The decrease in prey availability was associated with predator longevity, such that predators with less available prey had greater extinction risk. These results not only reveal long-term trends in network structure but suggest that prey species richness in ecological communities may shape large scale patterns of extinction and persistence among predators.Item DigApp and TaphonomApp: Two new open-access palaeontological and archaeological mobile apps(Palaeontologia electronica, 2020) Martín Perea, David Manuel; Abrunhosa, Ana; Domingo Martínez, María Soledad; Cantero, Enrique; Menéndez González, Iris; Blanco, Fernando; Carro Rodríguez, Patricia María; Domingo Martínez, Laura; Hernández Fernández, Manuel; Morales, JorgeTwo new paleontological and archaeological Android applications, DigApp and TaphonomApp, are presented in this manuscript. DigApp is intended to aid data collection, storage and management in archaeological and palaeontological excavations. DigApp allows easily recording of common field information such as spatial data and fossil identification data. Online and offline versions of DigApp were developed to fit all needs, and they can be modified according to the excavation particularities. TaphonomApp was created in order to assist taphonomists while carrying out detailed taphonomical evaluations both in the field and in the laboratory, making data collection quicker, homogeneous and overall, more efficient. DigApp and TaphonomApp are free, open-access and flexible software, that can be easily modified by any user (without the need of expertise in computing or coding) as explained in this paper. An in-depth guide on how to modify the apps is provided within this paper. DigApp and TaphonomApp have been used during palaeontological excavations carried out at one of the Batallones Butte vertebrate sites (Batallones-10, Middle Miocene) in the Madrid basin (Spain).
