A data set was generated thorugh surveys to establish a baseline inforamtion for a project entitled "Innovations in Technology, Institutional and Extension Approaches towards Sustainable Agriculture and enhanced Food and Nutrition Security in Africa (Acronym - InnovAfrica)". The InnovAfrica is a consortium of 16 institutions comprising five institutions from Europe and eleven institutions from Africa and the project was implemented in six countries of eastern and southern Africa namely Ethiopia, Kenya, Malawi, Rwanda, South Africa...

A consortium of 16 institutions comprising five institutions from Europe and eleven institutions from Africa implemented a project entitled "Innovations in Technology, Institutional and Extension Approaches towards Sustainable Agriculture and enhanced Food and Nutritional Security in Africa (InnovAfrica)" in six countries of eastern and southern Africa namely Ethiopia, Kenya, Malawi, Rwanda, South Africa and Tanzania from June 2017 to November 2021. The InnovAfrica project collected endline data from 12 pilot sites (two sites per country)...

High levels of inbreeding with spatial and host-associated structure in lice of an endangered freshwater seal

Stephany Virrueta Herrera, Tommi Nyman, Kevin Johnson, Andrew Sweet, Eeva Ylinen & Mervi Kunnasranta
Host-specialist parasites of endangered large vertebrates are in many cases more endangered than their hosts. In particular, low host population densities and reduced among-host transmission rates are expected to lead to inbreeding within parasite infrapopulations living on single host individuals. Furthermore, spatial population structures of directly-transmitted parasites should be concordant with those of their hosts. Using population genomic approaches, we investigated inbreeding and population structure in a host-specialist seal louse (Echinophthirius horridus) infesting the Saimaa...

Emerging stability of forest productivity by mixing two species buffers temperature destabilizing effect

Miren Del Rio, Ricardo Ruiz‐Peinado, Stig‐Olof Holm, Aris Jansons, Thomas Nord‐Larsen, Kris Verheyen, Andrés Bravo‐Oviedo, Hans Pretzsch, Ricardo Ruiz-Peinado, Hervé Jactel, Lluís Coll, Magnus Löf, Jorge Aldea, Christian Ammer, Admir Avdagić, Ignacio Barbeito, Kamil Bielak, Felipe Bravo, Gediminas Brazaitis, Jakub Cerný, Catherine Collet, Sonia Condés, Lars Drössler, Marek Fabrika, Michael Heym … & Andrés Bravo-Oviedo
The increasing disturbances in monocultures around the world are testimony to their instability under global change. Many studies have claimed that temporal stability of productivity increase with species richness, although the ecological fundaments have mainly been investigated through diversity experiments. To adequately manage forest ecosystems, it is necessary to have a comprehensive understanding of the effect of mixing species on the temporal stability of productivity and the way in which this it is influenced by...

Imprints of latitude, host taxon and decay stage on fungus-associated arthropod communities

Janne Koskinen, Nerea Abrego, Eero Vesterinen, Torsti Schulz, Tomas Roslin & Tommi Nyman
Interactions among fungi and insects involve hundreds of thousands of species. While insect communities on plants have formed some of the classic model systems in ecology, fungus-based communities and the forces structuring them remain poorly studied by comparison. We characterize the arthropod communities associated with fruiting bodies of eight mycorrhizal basidiomycete fungus species from three different orders along a 1200-km latitudinal gradient in northern Europe. We hypothesized that—matching the pattern seen for most insect taxa...

Neutral processes related to regional bee commonness and dispersal distances are important predictors of plant-pollinator networks along gradients of climate and landscape conditions

Markus Arne Sydenham, Zander Venter, Stein Moe, Katrine Eldegard, Michael Kuhlmann, Trond Reitan, Claus Rasmussen, Robert Paxton, Yoko Dupont, Astrid Skrindo, Megan Nowell, Stein Hegland, Anders Nielsen, Jens Olesen & Graciela Rusch
Understanding how niche-based and neutral processes contribute to the spatial variation in plant-pollinator interactions is central to designing effective pollination conservation schemes. Such schemes are needed to reverse declines of wild bees and other pollinating insects and to promote pollination services to wild and cultivated plants. We used data on wild bee interactions with plants belonging to the four tribes Loteae, Trifolieae, Anthemideae, and either spring- or summer-flowering Cichorieae, sampled systematically along a 682km latitudinal...

Dataset from: A curated DNA barcode reference library for parasitoids of northern European cyclically outbreaking geometrid moths

Tommi Nyman, Saskia Wutke, Elina Koivisto, Tero Klemola, Mark Shaw, Tommi Andersson, Håkon Haraldseide, Snorre Hagen, Ryosuke Nakadai & Kai Ruohomäki
Large areas of forests are annually damaged or destroyed by outbreaking insect pests. Understanding the factors that trigger and terminate such population eruptions has become crucially important, as plants, plant-feeding insects, and their natural enemies may respond differentially to the ongoing changes in the global climate. In northernmost Europe, climate-driven range expansions of the geometrid moths Epirrita autumnata and Operophtera brumata have resulted in overlapping and increasingly severe outbreaks. Delayed density-dependent responses of parasitoids are...

Using semiochemicals to predict biotic resistance and facilitation of invading phytophagous insects

Rylee Isitt, Bjørn Økland, Paal Krokene, Jon Sweeney, Stephen Heard & Deepa Pureswaran
Invasive species are leading causes of biodiversity loss and economic damage. Allocating limited resources towards prevention and management of invasions requires risk assessments based on ecological knowledge for species of potential concern. Interactions of potentially invasive species with heterospecifics in a novel community will contribute to biotic resistance and facilitation experienced by the invader, and thus the likelihood of establishment. To experimentally predict heterospecific interactions, we conducted field experiments using synthetic aggregation-pheromone lures to measure...
