Pollinator attractiveness of five weeds [PDF]

open access: yes, 2018
The number of pollinators in agro-ecosystems world wide has declined alarminglyin recent decades due to poora gricultural practices such as the intensive use of pesticides and monocultures.Postprint (published ...

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

open access: yesEcography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Resistance management in Vf apple scab resistant organic apple orchards [PDF]

open access: yes, 2006
Modern Vf scab resistant apple varieties open the way for organic growers to lower fungicide input, higher yields, better skin quality, more biological control for mites and insect pests and better consumer acceptance of their management practices ...

The pollination of tomatoes.

open access: yesNetherlands Journal of Agricultural Science, 1957
Studies were carried out on the effect of pollination on fruit set, normal fruit growth, earliness of yield and size of fruit. A high positive correlation was found between the number of seeds per fruit and the fruit weight. When flowers were pollinated with a mixture of inert powder and pollen, fruits were larger and earlier as the proportion of ...

‘ILSM': a package to analyze the interconnection structure of tripartite interaction networks

open access: yesEcography, EarlyView.
In natural or human‐disturbed ecosystems, ecological networks often comprise multiple interaction types, which have been increasingly represented by multipartite ecological networks. One important aspect of their network architecture is how different interaction types or subnetworks are interconnected by connector species, here defined as the ...

Quantifying landscape‐level biodiversity change in an island ecosystem: a 50‐year assessment of shifts in the Hawaiian avian community

open access: yesEcography, EarlyView.
Hawaii has experienced profound declines in native avifauna alongside the introduction of numerous bird species. While site‐specific population studies are common, landscape‐level analyses of avian population dynamics are rare, particularly in island ecosystems. To address this gap, we used a density surface model to create a spatio‐temporal projection
