#Gülpe has so many amazing spots and paths and even more plants and insects :) (The only thing better is going to be the Borscht on Saturday) @oksanabuzh.bsky.social @dariiaborovyk.bsky.social

Honored to receive the Best Paper Award from @jpecol.bsky.social 🏆

Our paper shows that multitrophic biodiversity enhances ecosystem functions, services, and ecological intensification in agriculture.

Paper out in Biological Conservation 🎉

Traditional management maintains species-rich grassland 🌼

▶️19% plant species dispersed via livestock feces💩
▶️Grassland cleaning🧹 boosts diversity
▶️Low-intensity grazing🐄 & manuring💩 shape plant composition without reducing diversity 👩‍🌾

Pathogens and herbivores differ in key life history characteristics, and we expected that these might drive differences in terminology, patterns, and hypotheses in the published literature.
Figure 1 from our paper showing biological differences in life-history traits (bold text) across above- and belowground compartments for pathogenic and herbivorous consumer groups. some consumers (i.e., leaf miners and parasitic nematodes) exhibit traits that span both categories.

The bold text for pathogens reads: "span a wider taxonomic breadth (viruses, bacteria, and multi-cellular eukaryotes), limited host choice, may require vectors, fast reproduction".
 
The text for herbivores reads: "span a narrower taxonomic breadth (restricted to animals), consumed by predators, movement, range in body size, host choice."

Lets the sampling begin 🎉
Start of sampling in the #BlühenderCampus of the @freieuniversitaet.bsky.social to assess the effects of management intensity on biodiversity 🌼🐛🐞🐿️ & functioning ♻️ of campus green spaces. Stay tuned for more 😉

Ich fühle mich auf jeden Fall seit 2017 wie eine Schallplatte mit Sprung: Qualität in der Standardisierung ist das Wichtigste, weil biologische Vielfalt sehr komplex ist…

New key finding:
Landscapes of fragmented habitat have lower diversity, at all scales, than do unfragmented landscapes.

Habitat fragmentation does not compensate for the loss of local (alpha) diversity by increasing the diversity among fragments (beta diversity).
www.nature.com/articles/s41...
The figure explaining the contrasting outcomes for diversity and local and landscape scales in continuous vs. fragmented landscapes. The right column (panel d) shows the cases where increasing inter-fragment diversity (increasing beta diversity among fragments) compensates for loss of local (alpha) diversity results in an increase in regional (Gamma) diversity. Fragmentation is 'bad' for diversity when loss of alpha and beta diversity combine to cause landscape-wide declines in gamma diversity.

The effects of different drivers and their scale-dependency operated through different mechanisms:
The mechanisms underlying the effects of the study environmental drivers on local diversity at small (10 m2 plots) and larger (100 m2 plots) fine-grain sizes (a) and on β-diversity—the scaling factor among the two scales (b). https://doi.org/10.1002/ece3.70941
oksanabuzh.bsky.social
We investigated how climate, soil properties, abiotic disturbance, and land use influence plant diversity across two fine grain sizes (10 vs 100 m2) in various grassland types in Ukraine. The strength of most of the effects of these drivers varied between spatial scales, affecting β-diversity.
Scale-dependent effects of environmental drivers on species richness and evenness at small (10 m2) and larger (100 m2) fine-grain plots. Points show the standardized effect sizes of each environmental driver (marked by colors of points) on the diversity measures at 10 m2 scale (x-axis) compared to 100 m2 (y-axis). The solid gray line indicates the 1: 1 line expected if effect sizes were not scale-dependent. Points above and below this line indicate effect sizes that are larger or smaller, respectively, as grain size increases. https://doi.org/10.1002/ece3.70941

Legumes strengthened the top-down control of primary consumers. Biomass stocks and energy flows were responsive to different biodiversity facets. Targeted grassland management would profit from focusing on specific plant diversity facets depending on the ecosystem function or service of interest.
oksanabuzh.bsky.social
We showed that plant diversity constrains consumer functioning by means other than only altered consumer biomass. The effects of plant species richness across the food web attenuated with higher trophic levels and often operated through mechanisms of plant functional-trait diversity.
