On the biological and genetic diversity in Neospora caninum [PDF]

open access: yes, 2010
Published: 22 March 2010Neospora caninum is a parasite regarded a major cause of foetal loss in cattle. A key requirement to an understanding of the epidemiology and pathogenicity of N.

The Shape of Species Abundance Distributions Across Spatial Scales

open access: yesFrontiers in Ecology and Evolution, 2021
Species abundance distributions (SADs) describe community structure and are a key component of biodiversity theory and research. Although different distributions have been proposed to represent SADs at different scales, a systematic empirical assessment ...

Mediterranean moth diversity is sensitive to increasing temperatures and drought under climate change

open access: yesScientific Reports, 2022
Climate change affects ecosystems worldwide and is threatening biodiversity. Insects, as ectotherm organisms, are strongly dependent on the thermal environment. Yet, little is known about the effects of summer heat and drought on insect diversity. In the

Estimating T-cell repertoire diversity: limitations of classical estimators and a new approach [PDF]

open access: yes, 2015
A highly diverse T-cell receptor (TCR) repertoire is a fundamental property of an effective immune system, and is associated with efficient control of viral infections and other pathogens. However, direct measurement of total TCR diversity is impossible.

Effects of moisture decrease on behavioural and life history traits in three species of terrestrial isopods

open access: yesThe European Zoological Journal, 2023
In the context of the predicted global warming, we investigated whether the feeding activity and the behaviour of three Oniscidean species (Porcellionides pruinosus, Porcellio laevis and Armadillidium tunisiense) would be affected by the relative ...

Effect of Phenological Stage and Rooting Enhancers on Physiological Parameters in Stem Cuttings in the Process of Rhizogenesis of Rosa × alba ‘Maiden’s Blush’

open access: yesAgriculture, 2020
Once-blooming roses belong to difficult-to-root. One-bud leafy cuttings have limited storage capacity, due to the small size of the stem, and are exposed to prolonged stress conditions.

Considering Intra-individual Genetic Heterogeneity to Understand Biodiversity [PDF]

open access: yes, 2019
In this chapter, I am concerned with the concept of Intra-individual Genetic Hetereogeneity (IGH) and its potential influence on biodiversity estimates. Definitions of biological individuality are often indirectly dependent on genetic sampling -and vice ...

Mosquitoes on a chip—environmental DNA-based detection of invasive mosquito species using high-throughput real-time PCR [PDF]

open access: yesPeerJ
The monitoring of mosquitoes is of great importance due to their vector competence for a variety of pathogens, which have the potential to imperil human and animal health. Until now mosquito occurrence data is mainly obtained with conventional monitoring

Looking for Hidden Enemies of Metabarcoding: Species Composition, Habitat and Management Can Strongly Influence DNA Extraction while Examining Grassland Communities

open access: yesBiomolecules, 2021
Despite the raising preoccupation, the critical question of how the plant community is composed belowground still remains unresolved, particularly for the conservation priority types of vegetation.

The Intersections of Biological Diversity and Cultural Diversity: Towards Integration [PDF]

open access: yes, 2009
There is an emerging recognition that the diversity of life comprises both biological and cultural diversity. In the past, however, it has been common to make divisions between nature and culture, arising partly out of a desire to control nature.
