Precipitation‐mediated asymmetric fitness consequences of nectar robbing in distylous Primula florindae

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Flowers with deep corollas are frequently associated with nectar robbing, a behaviour that often reduces pollen transfer and seed production. Robbing scars, however, may further affect plant reproductive success through rainwater entry into corolla tubes.

Different Selectivity in Fungal Communities Between Manure and Mineral Fertilizers: A Study in an Alkaline Soil After 30 Years Fertilization

Frontiers in Microbiology, 2018
Fertilizer application has contributed substantially to increasing crop yield. Despite the important role of soil fungi in agricultural production, we still have limited understanding of the complex responses of fungal taxonomic and functional groups to ...

Updated Chorotypes of Terrestrial Vertebrates Shed New Light on Zoogeographical Regions in China

Integrative Zoology, EarlyView.
Chorotype represents a fundamental concept for identifying groups of species that share similar distribution patterns. However, the last comprehensive revision of animal chorotypes in China was performed more than a decade ago. Here, we update the chorotype classifications for 1040 species and propose an updated zoogeographical regionalization scheme ...

An insight into the different responses to salt stress in growth characteristics of two legume species during seedling growth

Frontiers in Plant Science
Legumes play a crucial role in the restoration and utilization of salinized grassland. To explore the physiological response mechanism of Astragalus membranaceus and Medicago sativa seedlings to salt stress, salt stress culture experiments with five NaCl

Direct Evidence of the Geographic Origins of Horse in the Yaoheyuan Site From Ningxia, China

Archaeometry, EarlyView.
ABSTRACT In this study, It is explores the geographic origin of horses by analyzing the strontium isotope ratio of horses from the Yaoheyuan site, an important site in the northwest region of China during the Western Zhou Dynasty. The results show that most of the horses at the Yaoheyuan site were domesticated locally, while a small number came from ...

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Magnetic susceptibility evidence of monsoon variation on the Loess Plateau of central China during the last 130,000 years

, 1991
        The magnetic susceptibility of loess and paleosols in central China represents a proxy climate index closely related to past changes of precipitation and vegetation, and thus to summer monsoon intensity.

Shifts in fungal communities drive soil profile nutrient cycling during grassland restoration

mBio
Soil microbial diversity and community life strategies are crucial for nutrient cycling during vegetation restoration. Although the changes in topsoil microbial communities during restoration have been extensively studied, the structure, life strategies,
