Study on Floral Syndrome and Breeding System of an Endangered Species Rhododendron nymphaeoides
Ecology and Evolution, Volume 15, Issue 12, December 2025.This study divided the flowering process of Rhododendron nymphaeoides into five periods and systematically investigated the floral traits, pollen morphology and viability, optimal solid media for in vitro pollen germination, storage temperature screening, pollen–ovule ratio and hybridization index, stigma receptivity, the effects of different ...

Nordic Journal of Botany, Volume 2025, Issue 12, December 2025.Campanula teucrioides Boiss. is a critically endangered species found in a single locality in western Turkey. Determining the population size of C. teucrioides and conducting reproductive biology studies are of great importance in determining the necessary strategy for the conservation of the species. The area where the plant distributed was determined

Modeling population dynamics of solitary bees in relation to habitat quality [PDF]
, 2001 To understand associations between habitat, individual behaviour, and population development of solitary bees we developed an individual-based model. This model is based on field observations of <i>Osmia rufa</i> (L) (Apoideae: Megachilidae ...

Estimating the ecological drivers of insect abundance when detection is imperfect
Journal of Animal Ecology, Volume 94, Issue 12, Page 2641-2654, December 2025.Using a field‐based mark–recapture approach, the authors demonstrate that habitat quality can simultaneously influence insect abundance and detection. Simulation also showed that prioritizing increased sampling intensity over adding more study sites can improve accuracy of standard modelling approaches including GLMs or GLMMs, which do not account for ...

Insect Science, Volume 32, Issue 6, Page 1911-1925, December 2025.• The bees Anthophora plumipes and Osmia cornuta had a higher occurrence probability of the neogregarine protozoan Apicystis bombi in more fragmented urban areas.• In the bee Halictus scabiosae and wasp Polistes dominula, hotter urban areas increased the likelihood of occurrence of viruses.• The viruses were found to be replicative in the samples, and ...
