Data set from Argentinian plots from: 'Untangling the importance of niche breadth and niche position as drivers of tree species abundance and occupancy across biogeographic regions '. Global Ecology and Biogeography 2020. https://doi.org/10.1111/geb.13139

Data package for 'Untangling the importance of niche breadth and niche position as drivers of tree species abundance and occupancy across biogeographic regions '. Global Ecology and Biogeography 2020. ABSTRACT Despite decades of interest in how ecological niches shape species commonness and rarity at local and regional scales, the relative importance of different niche mechanisms within and across ecosystems remains unresolved. We tested the relative importance of niche breadth (range of environmental conditions where species...

Andean non-volant small mammals: a dataset of community assemblages of non-volant small mammals from the high Andes

Edgardo M. Rengifo, Jorge Brito, Jorge Pablo Jayat, Raisa Cairampoma, Agustina Novillo, Natali Hurtado, Ignacio Ferro, Cesar E. Medina, Alonso Arguero, Sergio Solari, Jose Urquizo, Ariatna Villareal, Elena Vivar, Pablo Teta, Marcial Quiroga-Carmona, Guillermo D'Elía & Alexandre Reis Percequillo
Information from diversity inventories is used to study patterns of biodiversity and species distribution; likewise, it may be useful to identify priority areas for conservation, and to guide future sampling efforts. In this context, we compiled information on non-volant small mammal communities from the high Andes (> 2,000 m.). Here we present an open resource data set containing information diversity (species composition, number of individuals captured ), inventory design (type of traps, sampling efforts), and...

Nutrient balance and energy-acquisition effectiveness: Do birds adjust their fruit diet to achieve intake targets?

Pedro Blendinger, Tobias Nicolas Rojas, Andrés Ramírez-Mejía, Irene Bender, Silvia Lomáscolo, Julieta Magro, Maria Gabriela Nuñez Montellano, Román Ruggera, Mariana Valoy & Mariano Ordano
1. According to diet-regulation hypotheses, animals select food to regulate the intake of macronutrients or maximise energy feeding efficiency. Specifically, the nutrient balance model proposes that foraging is primarily a process of balancing multiple nutrients to achieve a nutritional intake target, while the energy maximisation model proposes that foraging aims to maximise energy. 2. Here, we evaluate the adjustment of fruit diets (the fruit-derived component of the diets) to nutritional and energy intake targets, characterizing...

Data from: Description and phylogenetic position of a new species of Oreobates (Anura: Craugastoridae) from northwestern Argentina

Martín O. Pereyra, Darío E. Cardozo, Jorge Baldo & Diego Baldo
We describe a new species of Oreobates from Jujuy, Argentina. The new species is clearly diagnosable from other species of Oreobates by a combination of morphological characters and supported by molecular evidence (genetic distance and phylogenetic analysis). We also provide taxonomic comments about O. discoidalis and O. barituensis, emphasizing the need for an exhaustive revision of these species

Untangling the importance of niche breadth and niche position as drivers of tree species abundance and occupancy across biogeographic regions

Dilys M. Vela Díaz, Cecilia Blundo, Leslie Cayola, Alfredo F. Fuentes, Lucio R. Malizia & Jonathan A. Myers
Aim: Ecological niches shape species commonness and rarity, yet the relative importance of different niche mechanisms within and across ecosystems remains unresolved. We tested the influence of niche breadth (range of environmental conditions where species occur) and niche position (marginality of a species’ environmental distribution relative to the mean environmental conditions of a region) on tree-species abundance and occupancy across three biogeographic regions. Location: Argentinian Andes; Bolivian Amazon; Missouri Ozarks. Time period: 2002–2010. Major taxa...

Data from: The role of trait combination in the conspicuousness of fruit display among bird-dispersed plants

Mariano Ordano, Pedro G. Blendinger, Silvia B. Lomáscolo, Natacha P. Chacoff, Mariano S. Sánchez, María G. Núñez-Montellano, Julieta Jiménez, Román A. Ruggera & Mariana Valoy
In visually-driven seed dispersal mutualisms, natural selection should promote plant strategies that maximize fruit visibility to dispersers. Plants might increase seed dispersal profitability by increasing conspicuousness of fruit display, understood as a plant strategy to maximize fruit detectability by seed dispersers. The role of different plant traits in fruit choice and consumption by seed dispersers has been broadly studied. However, there is no clear evidence about the importance of the traits that increase conspicuousness of...

Forest biomass in subtropical Andes: Plots data

Cecilia Blundo, Agustina Malizia, Lucio R. Malizia & Jeremy W. Lichstein
Forest biomass plays an important role in the global carbon cycle. Therefore, understanding the factors that control forest biomass stocks and dynamics is a key challenge in the context of global change. We analyzed data from 60 forest plots in the subtropical Andes (22-27.5° S and 300-2300 m asl) to describe patterns and identify drivers of aboveground biomass (AGB) stocks and dynamics. We found that AGB stocks remained roughly constant with elevation due to compensating...

Data from: Unravelling the distinctive craniomandibular morphology of the Plio‐Pleistocene Eumysops in the evolutionary setting of South American octodontoid rodents (Hystricomorpha)

A. Itatí Olivares, Alicia Álvarez, Diego H. Verzi, S. Ivan Perez & Nahuel A. De Santi
Abstract: Echimyidae is a species-rich clade of Neotropical rodents, which diversified in association with forested biomes. A few lineages were adapted to open environments from southern South America since the late Miocene. Eumysops is one of these southern echimyids, and its peculiar craniomandibular morphology has been assumed to be a result of adaptation to open environments. We performed a geometric morphometric analysis of craniomandibular shape variation in order to explore if Eumysops is, as suspected,...

Snout shape and masticatory apparatus of the rodent-like mesotheriid ungulates (Typotheria, Notoungulata): Exploring evolutionary trends in dietary strategies through ancestral reconstructions

Marcos D. Ercoli & Matías A. Armella
Mesotheriidae includes small to medium-sized herbivores that belong to the so-called South American native ungulates. Mesotheriids radiated from the early Oligocene to the early–middle Pleistocene and were traditionally grouped into two subfamilies: Trachytheriinae and Mesotheriinae. Beyond the conspicuous fossil record of the group, little is known about its palaeobiology and, particularly, the dietary habits. So far, different studies suggest grazing habits, similar to extant ungulates, but recent contributions are challenging this vision to some degree....

Data and code: Global and regional ecological boundaries explain abrupt spatial discontinuities in avian frugivory interactions

Donatti, Carine Emer, Mauro Galetti, Ruben Heleno, Pedro Jordano, Ícaro Menezes, José Carlos Morante-Filho, Marcia C. Muñoz, Eike Lena Neuschulz, Marco Aurélio Pizo, Marta Quitián, Roman A. Ruggera, Francisco Saavedra, Vinicio Santillán, Virginia Sanz D’Angelo, Matthias Schleuning, Luís Pascoal Da Silva … & Jason M. Tylianakis
Species interactions can propagate disturbances across space via direct and indirect effects, potentially connecting species at a global scale. However, ecological and biogeographic boundaries may mitigate this spread by demarcating the limits of ecological networks. We tested whether large-scale ecological boundaries (ecoregions and biomes) and human disturbance gradients increase dissimilarity among plant-frugivore networks, while accounting for background spatial and elevational gradients and differences in network sampling. We assessed network dissimilarity patterns over a broad spatial...
