The Pollination of Toadflax [PDF]

Nature, 1916
Linaria spuria, Miller, is a not uncommon weed of cornfields on calcareous soils in the Midlands and south of England, in western, central, and southern Europe, in, northern Africa, and in western Asia, and it occurs adventitiously in North America. I have never observed insects pollinating the flower.

Using the Honey Bee (Apis mellifera L.) Cell Line AmE‐711 to Evaluate Insecticide Toxicity

Environmental Toxicology and Chemistry, Volume 42, Issue 1, Page 88-99, January 2023., 2023
Abstract One of the main contributors to poor productivity and elevated mortality of honey bee colonies globally is insecticide exposure. Whole‐organism and colony‐level studies have demonstrated the effects of insecticides on many aspects of honey bee biology and have also shown their interactions with pathogens.

Valuing insect pollination services with cost of replacement. [PDF]

PLoS ONE, 2008
Value estimates of ecosystem goods and services are useful to justify the allocation of resources towards conservation, but inconclusive estimates risk unsustainable resource allocations.

Phylogenomics, historical biogeography, and diversification of leaf traits in the Malagasy‐endemic genus Uncarina (Pedaliaceae)

American Journal of Botany, EarlyView.
Abstract Premise Uncarina contains 14 species of woody plants endemic to Madagascar. Its occurrence across dryland biomes on the island make it an interesting system to study the diversification of the flora. Methods Using samples of all species and 512 nuclear loci, we reconstructed phylogenetic trees to examine species relationships and assess their ...

Defining the Biologically Plausible Taxonomic Domain of Applicability of an Adverse Outcome Pathway: A Case Study Linking Nicotinic Acetylcholine Receptor Activation to Colony Death

Environmental Toxicology and Chemistry, Volume 42, Issue 1, Page 71-87, January 2023., 2023
Abstract For the majority of developed adverse outcome pathways (AOPs), the taxonomic domain of applicability (tDOA) is typically narrowly defined with a single or a handful of species. Defining the tDOA of an AOP is critical for use in regulatory decision‐making, particularly when considering protection of untested species.

Recognition of flowers by pollinators

Current Opinion in Plant Biology, 2006
The flowers of angiosperm plants present us with a staggering diversity of signal designs, but how did this diversity evolve? Answering this question requires us to understand how pollinators analyze these signals with their visual and olfactory sense organs, and how the sensory systems work together with post-receptor neural wiring to produce a ...

Expanding the Tyrosine Kinase Domain of CSF1R? A Case Report From an Adult‐Onset Leukoencephalopathy

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Adult‐onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP), also termed hereditary diffuse leukoencephalopathy with spheroids‐1 (HDLS1), results from mutations in the CSF1R gene and leads to progressive leukoencephalopathy.

Hosts, microbiomes, and the evolution of critical windows

Evolution Letters, Volume 6, Issue 6, Page 412-425, December 2022., 2022
Abstract The absence of microbial exposure early in life leaves individuals vulnerable to immune overreaction later in life, manifesting as immunopathology, autoimmunity, or allergies. A key factor is thought to be a “critical window” during which the host's immune system can “learn” tolerance, and beyond which learning is no longer possible.

Effect of Simulated Autogamy and Allogamy on the Success of Cephalanthera longifolia and Cephalanthera rubra (Orchidaceae) Fruit Set

Diversity
Detailed knowledge of reproductive traits and success is essential for the effective conservation of rare and endangered species. It has been reported that Cephalanthera longifolia and C.

Fruit set and yield of pear cultivars as affected by reduced bee pollination period

International Journal of Horticultural Science, 2009
Results of our experiments prove that pear is more or less sensitive to the reduced bee pollination period. However, the reaction (or the sensitivity) of cultivars may be different to the reduced bee pollination.
