Data from: Heterogeneity of ecological patterns, processes and funding of marine manipulative field experiments conducted in Southeastern Pacific coastal ecosystems

Moisés A. Aguilera, Johanne Dobringer & Ignacio J. Petit
Ecological manipulative experiments conducted in marine coastal ecosystems have substantially improved ecological theory during the last decades, and have provided useful knowledge for the management and conservation of coastal ecosystems. Although different studies report global trends in ecological patterns worldwide, Southeastern Pacific coastal ecosystems have been poorly considered. Given that the SE Pacific coast encompasses diverse coastal ecosystems, consideration of studies conducted along this range can shed light on the heterogeneity of processes regulating coastal...

The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are...

Data from: A down-shifting Eu 3+ -doped Y 2 WO 6 /TiO 2 photoelectrode for improved light harvesting in dye-sensitized solar cells

Jaime Llanos, Ivan Brito, Dario Espinoza, Ramkumar Sekar & Paulraj Manidurai
Y1.86Eu0.14WO6 phosphors were prepared using a solid-state reaction method. Their optical properties were analysed, and they was mixed with TiO2, sintered, and used as a photoelectrode (PE) in dye-sensitized solar cells (DSSCs). The as-prepared photoelectrode was characterized by photoluminescence spectroscopy, diffuse reflectance, electrochemical impedance spectroscopy (EIS) and X-ray diffraction. The photoelectric conversion efficiency of the DSSC with TiO2:Y1.86Eu0.14WO6 (100:2.5) was 25.8% higher than that of a DSCC using pure TiO2 as PE. This high efficiency...

Data from: The modulating role of traits on the biogeographic dynamics of chondrichthyans from the Neogene to the present

Jaime A. Villafana & Marcelo M. Rivadeneira
The environmental transformations that occurred during the Neogene had profound effects on spatio-temporal biodiversity patterns, yet the modulating role of traits (i.e. physiological, ecological and life history traits) remains little understood. We tested this idea using the Neogene fossil record of chondrichthyans along the temperate Pacific coast of South America (TPSA). Information of georeferenced occurrences and ecological and life history information of 38 chondrichthyan fossil genera in 42 Neogene sites was collected. Global georeferenced records...

Data from: Rare long-distance dispersal of a marine angiosperm across the Pacific Ocean

Aim: Long-distance dispersal (LDD) events occur rarely but play a fundamental role in shaping species biogeography. Lying at the heart of island biogeography theory, LDD relies on unusual events to facilitate colonisation of new habitats and range expansion. Despite the importance of LDD, it is inherently difficult to quantify due to the rarity of such events. We estimate the probability of LDD of the seagrass Heterozostera nigricaulis, a common Australian species, across the Pacific Ocean...

Data from: The herbivorous fish, Aplodactylus punctatus, as a potential facilitator of dispersal of the bottom kelp, Lessonia trabeculata, in Chile

Alejandro Pérez-Matusa & Fadia Tala
Kelp forests are productive marine habitats known to facilitate many trophic and non-trophic interactions. While much of our understanding comes from positive effects of kelp on associated fauna, few studies focus on potential feedbacks that such fauna may provide to benefit kelp. This study aims to analyze the positive interactions between two closely associated fish and kelp species. Lessonia trabeculata, the bottom kelp, and the herbivorous fish, Aplodactylus punctatus, were sampled at four sites off...

Data from: Thorson’s rule, life history evolution and diversification of benthic octopuses (Cephalopoda: Octopodoidea)

Christian M. Ibáñez, Enrico L. Rezende, Roger D. Sepúlveda, Jorge Avaria-Llautureo, Cristián E. Hernández, Javier Sellanes, Elie Poulin & María Cecilia Pardo-Gandarillas
Here we evaluate the so-called Thorson’s rule, which posits that direct-development and larger eggs are favored towards the poles in marine organisms and whose validity been the subject of considerable debate in the literature, combining an expanded phenotypic dataset encompassing 60 species of benthic octopuses with a new molecular phylogeny. Phylogenetic reconstruction shows two clades: clade 1 including species of the families Eledonidae, Megaleledonidae, Bathypolypodidae and Enteroctopodidae, and clade 2 including species of Octopodidae. Egg...

Data from: Asymmetric competitive effects during species range expansion: an experimental assessment of interaction strength between ‘equivalent’ grazer species at their range overlap

Moises A. Aguilera, Nelson Valdivia, Stuart Jenkins, Sergio A. Navarrete & Bernardo Broitman
1. Biotic interactions are central to the development of theory and concepts in community ecology; experimental evidence has shown their strong effects on patterns of population and community organization and dynamics over local spatial scales. The role of competition in determining range limits and preventing invasions at biogeographic scales is more controversial, partly because of the complexity of processes involved in species colonization of novel habitats and the difficulties in performing appropriate manipulations and controls....
