Genetic, phenotypic and ecological differentiation suggests incipient speciation in two Charadrius plovers along the Chinese coast

BMC Evolutionary Biology, 2019
Background Speciation with gene flow is an alternative to the nascence of new taxa in strict allopatric separation. Indeed, many taxa have parapatric distributions at present. It is often unclear if these are secondary contacts, e.g.

Ecological Factors in Speciation of Peromyscus [PDF]

Evolution, 1950
Mice of the American genus Peromyscus are among the several kinds of animals that are particularly useful for study of the factors involved in speciation. This genus is widely distributed over North and Central America, and one or more of the fifty-five named species occurs in almost every part of these areas. Representatives of the genus occupy a wide

Formulation‐Dependent Cytotoxic Effects of Commercial and Analytical‐Grade Mancozeb in C6 Glial Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Mancozeb (MZ) is a widely used dithiocarbamate fungicide composed of manganese (Mn) and zinc (Zn) complexes. Increasing concern has been raised regarding its occupational and human health relevance, particularly due to its neurotoxic potential associated with Mn‐related cellular dysfunction.

Nitrogen Fertilization Temporarily Enhances Phosphatase Activity in a High‐P Loamy Sand

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Efficient plant utilization of soil phosphorus (P) is essential to reduce dependence on mineral P fertilizers in intensive agriculture. Input of mineral nitrogen (N) fertilizers and its chemical form may influence the activity of P mineralizing enzymes, but how this interaction operates under field conditions in a soil with high P ...

Nutrient composition and heavy metal accumulation in water hyacinth [Eichhornia crassipes (Mart.) Solms] and water lettuce (Pistia stratiotes L.) from the Dande River, Nepal: Implications for use as alternative feed resources

JSFA reports, EarlyView.
Abstract Background The proliferation of invasive aquatic macrophytes poses a significant ecological challenge globally, while many tropical regions face chronic shortages of affordable livestock feed. This study addresses this dual problem by assessing two invasive species, water hyacinth (Eichhornia crassipes) and water lettuce (Pistia stratiotes ...

Proteins Associated with Salinity Adaptation of the Dinoflagellates: Diversity and Potential Involvement in Species Evolution

Diversity
Protists inhabit marine, brackish and fresh waters. The salt barrier plays an important role in the origin of their diversity. Salinity tolerance differs among species and sometimes even among different strains of the same species, indicating local ...

Long‐Term Straw Returning Combined With Mineral Fertilization Enhances Soil Quality but Elevates P Loss Risks in a Subtropical Rice–Wheat Rotation System, Central China

Land Degradation &Development, EarlyView.
ABSTRACT Long‐term straw returning is widely promoted to improve soil quality in intensive cropping systems, yet its combined effects with mineral fertilization on soil quality and phosphorus (P) loss risks remain unclear. Using a 16‐year field experiment in a rice–wheat rotation system, we evaluated the impacts of straw returning (S), NPK ...

The latitudinal variation in amphibian speciation rates revisited

Communications Biology
Speciation can increase regional species richness, however, our knowledge of how and why speciation rates vary across space is still incomplete. Using comprehensive information on species distributions and their phylogenetic relationships, we describe ...
