Data from: Fitness of an allopolyploid rupicolous fern compared to its diploid progenitors: From sporogenesis to sporophyte formationEmilia Pangua, Santiago Pajarón & Luis G. Quintanilla
PREMISE OF THE STUDY: When two populations of related cytotypes grow in sympatry, the rarer cytotype tends to be excluded due to a frequency-dependent mating disadvantage. Evolutionary models predict that polyploids, which are typically the rarer cytotype upon first formation, should have higher relative fitness and/or higher selfing rates to establish and then coexist with diploid parents. METHODS: We compared performance in early recruitment among three co-occurring rupicolous fern species: the allotetraploid Cheilanthes tinaei and...
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: Combining correlative and mechanistic niche models with human activity data to elucidate the invasive potential of a sub-Antarctic insectLuis Pertierra, Pedro Aragón, Miguel Olalla-Tarraga, Greta Vega, Grant Duffy, Pete Convey, Scott Hayward, Kevin Hughes & Jesamine Bartlett
Aim Correlative Species Distribution Models (SDMs) are subject to substantial spatio-temporal limitations when historical occurrence records of data-poor species provide incomplete and outdated information for niche modelling. Complementary mechanistic modelling techniques can, therefore, offer a valuable contribution to underpin more physiologically-informed predictions of biological invasions, the risk of which is often exacerbated by climate change. In this study we integrate physiological and human pressure data to address the uncertainties and limitations of correlative SDMs and...
1. Multiple ecosystem functions need to be considered simultaneously to manage and protect the many ecosystem services that are essential to people and their environments. Despite this, cost effective, tangible, relatively simple, and globally-relevant methodologies to monitor in situ soil multifunctionality, i.e. the provision of multiple ecosystem functions by soils, have not been tested at the global scale. 2. We combined correlation analysis and structural equation modelling to explore whether we could find easily measured,...
Opposite latitudinal patterns for bird and arthropod predation revealed in the experiments with differently colored artificial preyElena Zvereva, Bastien Castagneyrol, Tatiana Cornelissen, Anders Forsman, Juan Antonio Hernández-Agüero, Tero Klemola, Lucas Paolucci, Vicente Polo, Norma Salinas, K. Jurie Theron, Guorui Xu, Vitali Zverev & Mikhail Kozlov
The strength of biotic interactions is generally thought to increase towards the equator, but support for this hypothesis is contradictory. We explored whether predator attacks on artificial prey of eight different colours vary among climates and whether this variation affects the detection of latitudinal patterns in predation. The data set provides number of damage marks on each of 1320 plasticine caterpillars of eight different colours, which were attached to branches of woody plants and exposed...
