A general stochastic model for sporophytic self-incompatibility [PDF]

, 2011
Disentangling the processes leading populations to extinction is a major topic in ecology and conservation biology. The difficulty to find a mate in many species is one of these processes.

Using citizen science to monitor pollination services [PDF]

, 2015
1. Pollination by insects is a vital ecosystem service and the need for its assessment is increasing in recognition and political pressure, but there are currently no large-scale systematic monitoring schemes in place to measure the direct provision of ...

Self-supervised Visual Attribute Learning for Fashion Compatibility [PDF]

2021 IEEE/CVF International Conference on Computer Vision Workshops (ICCVW), 2020
Many self-supervised learning (SSL) methods have been successful in learning semantically meaningful visual representations by solving pretext tasks. However, prior work in SSL focuses on tasks like object recognition or detection, which aim to learn ...

Evolution towards self‐compatibility when mates are limited [PDF]

Journal of Evolutionary Biology, 2009
AbstractTheory of plant mating system evolution predicts the spread of self‐compatibility (SC) in a predominantly self‐incompatible population when inbreeding depression (ID; the decline in fitness because of selfing) is small and when compatible mates are limited.

Independent origins of self‐compatibility in Arabidopsis thaliana [PDF]

Molecular Ecology, 2007
AbstractThe evolution from outcrossing based on self‐incompatibility (SI) to a selfing system is one of the most prevalent transitions in flowering plants. It has been suggested that the loss of SI in Arabidopsis thaliana is associated with pseudogene formation at the SCR male component of the S locus.

Expression and trans-specific polymorphism of self-incompatibility RNases in Coffea (Rubiaceae) [PDF]

, 2011
Self-incompatibility (SI) is widespread in the angiosperms, but identifying the biochemical components of SI mechanisms has proven to be difficult in most lineages. Coffea (coffee; Rubiaceae) is a genus of old-world tropical understory trees in which the
