Key Elements Affecting the Library’s CFU Concentration in Taiwan

open access: yesComplexity, Volume 2023, Issue 1, 2023., 2023
Public libraries are popular gathering places, so understanding the factors that contribute to colony‐forming unit (CFU) concentrations and how to minimize them is essential. This study aimed to investigate the factors that affect CFU concentrations in a public library, using air sampling (Bioluminescent ATP‐assay) and statistical analysis software ...

Around the world in 500 years: Inter‐regional spread of alien species over recent centuries

open access: yesGlobal Ecology and Biogeography, Volume 30, Issue 8, Page 1621-1632, August 2021., 2021
Abstract Aim The number of alien species has been increasing for centuries world‐wide, but temporal changes in the dynamics of their inter‐regional spread remain unclear. Here, we analyse changes in the rate and extent of inter‐regional spread of alien species over time and how these dynamics vary among major taxonomic groups. Location Global.

Evolutionary relationship of fat body endoreduplication and queen fecundity in termites. [PDF]

open access: yesEcol Evol, 2019
Our study links a tissue‐specific ploidy elevation to reproductive division of labor in social insects; ploidy analysis via flow cytometry across six phylogenetically diverse termites revealed that the fat body of queens contained more polyploid cells than that of other nonreproductive females.

X-ray tomographic analysis of the initial structure of the royal chamber and the nest-founding behavior of the drywood termite Incisitermes minor [PDF]

open access: yes, 2014
The nesting biology of the drywood termite, Incisitermes minor, is poorly understood. To date, no published data are available regarding the in situ nest-gallery development of I. minor.

Quantitative Changes in Hydrocarbons over Time in Fecal Pellets of Incisitermes minor May Predict Whether Colonies Are Alive or Dead [PDF]

open access: yes, 2010
Hydrocarbon mixtures extracted from fecal pellets of drywood termites are species-specific and can be characterized to identify the termites responsible for damage, even when termites are no longer present or are unable to be recovered easily.

Commodity risk assessment of oak logs with bark from the US for the oak wilt pathogen Bretziella fagacearum under an integrated systems approach

open access: yesEFSA Journal, Volume 18, Issue 12, December 2020., 2020
Abstract The European Commission submitted to the EFSA Panel on Plant Health a Dossier by USDA proposing a systems approach to mitigate the risk of entry of Bretziella fagacearum to the EU when trading oak logs with bark from the USA. Due to the forthcoming ban of methyl bromide (MB), the Dossier indicates sulfuryl fluoride (SF) as the substitute ...

Substantial direct fitness gains of workers in a highly eusocial ant

open access: yesMolecular Ecology, Volume 29, Issue 19, Page 3720-3730, October 2020., 2020
Abstract Hamilton's theory of inclusive fitness suggests that helpers in animal societies gain fitness indirectly by increasing the reproductive performance of a related beneficiary. Helpers in cooperatively breeding birds, mammals and primitively eusocial wasps may additionally obtain direct fitness through inheriting the nest or mating partner of the

Body size and sperm quality in queen‐ And worker‐produced ant males

open access: yesJournal of Evolutionary Biology, Volume 33, Issue 6, Page 842-849, June 2020., 2020
Workers in many ant species are capable of activating their ovaries and producing males, at least in the absence of a queen. In this study we tested, whether queen‐ and worker‐produced males differ in sperm quality and other physiological traits. We show that male quality traits varied considerably among colonies but differed only slightly between ...
