Pollination and Flower Structure

Pollination and Flower Structure

Flowers are the reproductive, seed-producing structures of angiosperms. Typically, flowers consist of sepals, petals, stamens, and carpels. Sepals and petals are the vegetative flower organs. Stamens and carpels are the reproductive organs.

Area of Science:

Biodiversity research
Ecological data mobilization
Citizen science in entomology

Background:

Natural history collections hold vast biodiversity and ecological data.
Community science can transcribe specimen data and perform morphological measurements.
Digitization initiatives generate specimen images suitable for analysis.

Purpose of the Study:

To investigate community science effectiveness for generating bee body size datasets from specimen images.
To assess community scientist engagement and measurement accuracy.
To evaluate the potential of citizen science for collections-based biodiversity research.

Main Methods:

Utilized the Notes from Nature platform for a specimen measurement task.
Engaged community scientists to estimate intertegular distance from bee specimen images.
Compared community scientist measurements with those from trained researchers.

Main Results:

High community scientist engagement and task completion (43.6 specimens/user on average).
Self-reported successful measurement rate of 98.0% of images.
Community scientist measurements were significantly larger than researcher measurements, with an average error of 2.3%.

Conclusions:

Community science is an effective approach for bee body size measurement in ecological studies.
The presented methods can guide future public engagement in biodiversity research.
Citizen science is particularly promising for measuring larger-bodied organisms where error is proportionally smaller.
