Data from: Evidence of functional species sorting by rainfall and biotic interactions: A community monolith experimental approach

Ana L. Peralta, Ana M. Sánchez, Arantzazu L. Luzuriaga, Francesco De Bello & Adrian Escudero
1. Understanding the mechanisms that underlie species assembly is a central concern in community ecology. Abiotic and biotic filters are probabilistic ‘sieves’ that allow species with certain functional traits to become part of the community, or not. We manipulated natural plant assemblieses in order to identify variations in the timings of biotic and abiotic filters that determine community trait assemblies. 2. We extracted soil portions when the investigated annual plant community was in its seed...

Habitat destruction is the single greatest anthropogenic threat to biodiversity. Decades of research on this issue have led to the accumulation of hundreds of data sets comparing species assemblages in larger, intact, habitats to smaller, more fragmented, habitats. Despite this, little synthesis or consensus has been achieved, primarily because of non‐standardized sampling methodology and analyses of notoriously scale‐dependent response variables (i.e., species richness). To be able to compare and contrast the results of habitat fragmentation...

Data from: Fitness of reciprocal F1 hybrids between Rhinanthus minor and Rhinanthus major under controlled conditions and in the field

Renate A. Wesselingh, Šárka Hořčicová & Khaled Mirzaei
The performance of first‐generation hybrids determines to a large extent the long‐term outcome of hybridization in natural populations. F1 hybrids can facilitate further gene flow between the two parental species, especially in animal‐pollinated flowering plants. We studied the performance of reciprocal F1 hybrids between Rhinanthus minor and R. major, two hemiparasitic, annual, self‐compatible plant species, from seed germination to seed production under controlled conditions and in the field. We sowed seeds with known ancestry outdoors...

Nest microhabitats and tree size mediate shifts in ant community structure across elevation in tropical rainforest canopies

Nichola Plowman, Ondrej Mottl, Vojtech Novotny, Clifson Idigel, Frank Jurgen Philip & Petr Klimes
Declines or mid-elevation peaks in invertebrate diversity with elevation are often attributed to climate and geometric constraints. However, vegetation structure may also drive diversity patterns, especially for tree-dwelling species, via its effects on microhabitat use and competitive interactions. Here we investigate these effects on the diversity and community structure of tree-nesting ants over elevation. We exhaustively sampled ant nests in 1254 trees within continuous plots of primary rainforest at low (200 m a.s.l.), mid (900...

Data from: Variation in plant functional traits is best explained by the species identity: stability of trait based species ranking across meadow management regimes

Ondrej Mudrak, Jiri Dolezal, Alena Vítová & Jan Leps
1. It is commonly assumed in trait-based studies that plant functional traits are species-specific, being more variable among species than among different environmental conditions. If the environment affects traits it is assumed that species react in a similar direction and conserve the functional distances. The rank of species based on the trait values is then unchanged, which justifies the use of species trait averages from database values. Such assumptions of species specificity are, however, increasingly...

Seasonal shifts of biodiversity patterns and species’ elevation ranges of butterflies and moths along a complete rainforest elevational gradient on Mount Cameroon

Vincent Maicher, Szabolcs Sáfián, Mercy Murkwe, Sylvain Delabye, Łukasz Przybyłowicz, Pavel Potocký, Ishmeal N. Kobe, Štěpán Janeček, Jan E. J. Mertens, Eric B. Fokam, Tomasz Pyrcz, Jiří Doležal, Jan Altman, David Hořák, Konrad Fiedler & Robert Tropek
Aim Temporal dynamics of biodiversity along tropical elevational gradients are unknown. We studied seasonal changes of Lepidoptera biodiversity along the only complete forest elevational gradient in the Afrotropics. We focused on shifts of species richness patterns, seasonal turnover of communities, and seasonal shifts of species’ elevational ranges, the latter often serving as an indicator of the global change effects on mountain ecosystems. Location Mount Cameroon, Cameroon. Taxon Butterflies and moths (Lepidoptera) Methods We quantitatively sampled...

Data from: Multidimensional ecological analyses demonstrate how interactions between functional traits shape fitness and life history strategies

Nuria Pistón Caballero, Francesco De Bello, André T. C. Dias, Lars Götzenberger, Bruno Henrique P. Rosado, Eduardo A. De Mattos, Roberto Salguero-Gómez & Carlos Perez Carmona
1.Traditionally, trait‐based studies have explored single‐trait‐fitness relationships. However, this approximation in the study of fitness components is often too simplistic, given that fitness is determined by the interplay of multiple traits, which could even lead to multiple functional strategies with comparable fitness (i.e. alternative designs). 2.Here we suggest that an analytical framework using boosted regression trees (BRT) can prove more informative to test hypotheses on trait combinations compared to standard linear models. We use two...

Habitats of Pleistocene megaherbivores reconstructed from the frozen fauna remains

Irena Axmanová, Jan Robovský, Lubomír Tichý, Jiri Danihelka, Elena Troeva, Albert Protopopov & Milan Chytrý
The Late Pleistocene landscape in northern Eurasia and North America was inhabited by a specific megafaunal complex, which largely disappeared during the Pleistocene/Holocene transition. Vegetation changes are considered as one of the factors responsible for these extinctions, but the structure and composition of the Pleistocene vegetation are still poorly known. Here we complement previous studies by comparing the taxonomic composition of the plant remains found in the gastrointestinal tracts of the frozen carcasses of Pleistocene...
