Male incubation feeding and fleas

Juan Manuel Peralta-Sánchez & Jan-Åke Nilsson
Parasites exert a strong selection pressure on their hosts as manifested in behavioural antiparasite traits to reduce negative impacts on fitness. The numerous nest-dwelling ecto-parasites residing in avian nests make altricial birds excellent model-systems for investigating the relationship between parasites and their hosts. Here, we experimentally increased natural levels of hen fleas (Ceratophyllus gallinae) in blue tit (Cyanistes caeruleus) nests during incubation, and tested their effects on parental incubation behaviours and reproductive performance. Our experimental...

Pollen records of Miocene thermal maximum

Jean-Pierre Suc, Gonzalo Jiménez-Moreno & Mostefa Bessedik
In order to identify the northern latitudinal limit between mangroves composed of Avicennia only and diversified mangroves during the Cenozoic thermal maxima, a special attention was paid to the Middle Miocene Climatic Optimum (MMCO: 17–14 Ma) in the Mediterranean s.l. region, including the Mediterranean Basin s.s. and its former brackish appendix, the Paratethys (Popescu et al., accepted, Journ. Biogeogr.). Pollen data come from forty-five biostratigraphically well-dated marine samples from 8 locations belonging to the MMCO....

COVID-19 evidence syntheses with artificial intelligence: an empirical study of systematic reviews

Juan R. Tercero-Hidalgo, Khalid S. Khan, Aurora Bueno-Cavanillas, Rodrigo Fernández-López, Juan F. Huete, Carmen Amezcua-Prieto, Javier Zamora & Juan M. Fernández-Luna
Objectives: A rapidly developing scenario like a pandemic requires the prompt production of high-quality systematic reviews, which can be automated using artificial intelligence (AI) techniques. We evaluated the application of AI tools in COVID-19 evidence syntheses. Study design: After prospective registration of the review protocol, we automated the download of all open-access COVID-19 systematic reviews in the COVID-19 Living Overview of Evidence database, indexed them for AI-related keywords, and located those that used AI tools....

Phenotypic and Genetic data for \"Evolution of fruit and seed traits during almond naturalization\"

Rafael Rubio De Casas, Andres Barea Marquez, Francisco Ocaña-Calahorro, Rodrigo Balaguer-Romano, José María Gómez, Eugene W. Schupp, Raquel Sanchez-Perez, Jesus Guillamon & Joanna Zhang
1- Cultivated plant species often naturalize and enter wild communities in a process known as feralization. To successfully feralize, crops must overcome ecological barriers and may undergo selection on certain traits, diverging phenotypically and genetically from their crop ancestors. In spite of the agronomic and ecological relevance of crop feralization, the eco-evolutionary dynamics driving it remain understudied. 2- In this paper, we evaluated phenotypic and genotypic differentiation in fruit and seed traits during the naturalization...

Warming and CO2 effects under oligotrophication on temperate phytoplankton communities

Marco J. Cabrerizo, M. Inmaculada Álvarez-Manzaneda, Elizabeth León-Palmero, Gerardo Guerrero-Jiménez, Lisette N. De Senerpont Domis, Sven Teurlincx & Juan M. González-Olalla
Eutrophication, global warming, and rising carbon dioxide (CO2) levels are the three most prevalent pressures impacting the biosphere. Despite their individual effects are well-known, it remains untested how oligotrophication (i.e. nutrients reduction) can alter the planktonic community responses to warming and elevated CO2 levels. Here, we performed an indoor mesocosm experiment to investigate the warming × CO2 interaction under a nutrient reduction scenario (40%) mediated by an in-lake management strategy (i.e. addition of a commercial...

Many roads to success: Different combinations of life-history traits provide accurate germination timing in seasonally dry environments

Diego Fernando Escobar, Rafael Rubio De Casas & Leonor P. Cerdeira Morellato
Germination timing is determined by several plant life-history traits. Seed dormancy regulates the time and place of early plant development and spreads recruitment risks over time. Dispersal phenology and syndrome can influence germination timing and buffer spatial heterogeneity. The ecological requirements for germination (the germination niche) can also influence when and where germination takes place. To date, the relative importance of each of these four traits to ensure the phenological adaptation of individual species in...

\"Mirando\" Bread and Roses (Ken Loach 2000). Representaciones sociales de la inmigración en los discursos de espectadores

Javier García Castaño, Damián Esteban Bretones & Tamar Abuladze
pp. 86-108. This article analyzes the social representations on the migration phenomenon and labor issues present in Ken Loach’s Bread and Roses (2000). It explores and compares the director’s discourse (creative instance), the producer’s synopsis, and the synopses made by the viewers (receiving instance) after watching the film within the framework of a university course, "Cinema and migrations". The analysis is made from the perspective of reception theory and critical discourse analysis.

Exposure to the Covid-19 pandemic and generosity in Spain

Diego Andrés Jorrat, Pablo Brañas-Garza, Antonio Alfonso, Teresa García Muñoz, Jaromir Kovarik & Antonio Espín
We report data from an online experiment, which allow us to study how generosity has changed during the initial explosive growth of the Covid-19 pandemic in Spain. We have gathered data from over a six-day period in which Covid-19-associated deaths in Spain, one of the most affected countries in the corresponding period, increased fourfold. In our experiment, participants could donate a fraction of a €100 prize to a charity. Our data are particularly rich in...
