Latitudinal pattern in community-wide herbivory does not match the pattern in herbivory averaged across common plant species

Elena Zvereva, Vitali Zverev, Vladimir Usoltsev & Mikhail Kozlov
1. The latitudinal herbivory hypothesis (LHH) predicts that plant losses to herbivores decrease from low to high latitudes. Although the LHH is a community-level hypothesis, it has been rarely tested with data on community-wide herbivory, i.e. the percentage of annual production of foliar biomass consumed by insects from all plant species at a given site. Therefore, we asked whether community-wide leaf herbivory follows the same latitudinal pattern as observed for an unweighted average of herbivory...

Threats from the air: damselfly predation on diverse prey taxa

Eero J. Vesterinen, Kari Kaunisto, , Mark Forbes, Andre Morrill, Anna Puisto, Ilari Sääksjärvi & Thomas Lilley
1. To understand the diversity and strength of predation in natural communities, researchers must quantify the total amount of prey species in the diet of predators. Metabarcoding approaches have allowed widespread characterization of predator diets with high taxonomic resolution. To determine the wider impacts of predators, researchers should combine DNA techniques with estimates of population size of predators using mark-release-recapture (MRR) methods, and with accurate metrics of food consumption by individuals. 2. Herein, we estimate...

Predation and parasitism on herbivorous insects change in opposite directions in a latitudinal gradient crossing a boreal forest zone

Elena Zvereva, Vitali Zverev & Mikhail Kozlov
1. The Latitudinal Biotic Interaction Hypothesis (LBIH) predicts that the strength of various biotic interactions decreases from low to high latitudes. Inconsistency between studies testing this hypothesis may result from variations among different types of interactions and among study systems. Therefore, exploration of multiple interactions within one system would help to disentangle latitudinal patterns across individual interactions and to evaluate latitudinal changes in the overall impact of enemies on prey. 2. We tested the prediction...

Data from: Island properties dominate species traits in determining plant colonizations in an archipelago system

Mikael Von Numers, Sami Aikio, Satu Ramula & Anne Muola
The extrinsic determinants hypothesis emphasizes the essential role of environmental heterogeneity in species’ colonization. Consequently, high resident species diversity can increase community susceptibility to colonizations because good habitats may support more species that are functionally similar to colonizers. On the other hand, colonization success is also likely to depend on species traits. We tested the relative importance of environmental characteristics and species traits in determining colonization success using census data of 587 vascular plant species...

Population genomics reveals repeated signals of adaptive divergence in the Atlantic salmon of northeastern Europe

Ksenia Zueva, Jaakko Lumme, Alexey Veselov, Craig Primmer & Victoria Pritchard
Our ability to examine genetic variation across entire genomes have enabled many studies searching for the genetic basis of local adaptation. These studies have identified numerous loci as candidates for differential local selection, however relatively few have examined the overlap among candidate loci identified from independent studies of the same species in different geographic areas or evolutionary lineages. We used an allelotyping approach with a 220K SNP array to characterize the population genetic structure of...

Data for: Microclimate structures communities, predation and herbivory in the High Arctic

Tuomas Kankaanpää, Nerea Abrego, Eero Vesterinen & Tomas Roslin
In a warming world, changes in climate may result in species-level responses as well as changes in community structure through knock-on effects on ecological interactions such as predation and herbivory. Yet, the links between these responses at different levels are still inadequately understood. Assessing how microclimatic conditions affect each of them at local scales provides information essential for understanding the consequences of macroclimatic changes projected in the future. Focusing on the rapidly changing High Arctic,...

Data from: Changes in age-structure over four decades were a key determinant of population growth rate in a long-lived mammal

John Jackson, Khyne Mar, Win Htut, Dylan Childs & Virpi Lummaa
1. A changing environment directly influences birth and mortality rates, and thus population growth rates. However, population growth rates in the short-term are also influenced by population age-structure. Despite its importance, the contribution of age-structure to population growth rates has rarely been explored empirically in wildlife populations with long-term demographic data. 2. Here, we assessed how changes in age-structure influenced short-term population dynamics in a semi-captive population of Asian elephants (Elephas maximus). 3. We addressed...

Data from: Paleoclimatic evolution as the main driver of current genomic diversity in the widespread and polymorphic Neotropical songbird Arremon taciturnus

Nelson Buainain, Roberta Canton, Gabriela Zuquim, Hanna Tuomisto, Tomas Hrbek, Hiromitsu Sato & Camila Ribas
Several factors have been proposed as drivers of species diversification in the Neotropics, including environmental heterogeneity, the development of drainage systems and historical changes in forest distribution due to climatic oscillations. Here, we investigate which drivers contributed to the evolutionary history and current patterns of diversity of a polymorphic songbird (Arremon taciturnus) that is widely distributed in Amazonian and Atlantic forests as well as in Cerrado gallery and seasonally-dry forests. We use genomic, phenotypic and...
