Geographic distribution and habitat preferences of Saxicola rubicola rubicola (Linnaeus, 1766), S. maurus variegatus (S.G. Gmelin, 1774), and S. m. armenicus (Stegman, 1935) inhabiting the Caucasian Isthmus and adjacent areas are described in detail. We examined the individual, sexual, age, seasonal and geographical variations of seven main diagnostic features of both plumage and morphometrics (exactly, the length of wing and tail) using 381 skin specimens. Substantially improved diagnoses of S. m. variegatus and S. m. armenicus are provided. After a thorough examination of the materials and history of the expedition of Samuel Gmelin in 1768–1774, and his description of Parus variegatus, it was concluded that the type locality of this taxon was the vicinity of Shamakhi in Azerbaijan not Enzeli in North-Western Turkey. It is also shown the fallacy of the recently proposed attribution of the holotype of the northern subspecies S. m. variegatus to the southern taxon S. m. armenicus and synonymisation of these names, as well as the replacement of the name S. m. variegatus by its junior synonym S. m. hemrichii Ehrenberg, 1833 for the northern subspecies.

Forests near rapidly industrialized and urbanized regions are often exposed to elevated CO2, increased N deposition, and heavy metal pollution. To date, the effects of elevated CO2 and/or increased N deposition on soil respiration (Rs) under heavy metal contamination are unclear. In this study, we firstly investigated Rs in Cd-contaminated model forests with CO2 enrichment and N addition in subtropical China. Results showed that Rs in all treatments exhibited similar clear seasonal patterns, with soil temperature being a dominant control. Cadmium addition significantly decreased cumulative soil CO2 efflux by 19% compared to the control. The inhibition of Rs caused by Cd addition was increased by N addition (decreased by 34%) was partially offset by elevated CO2 (decreased by 15%), and was not significantly altered by the combined N addition and rising CO2. Soil pH, microbial biomass carbon, carbon-degrading hydrolytic enzymes, and fine root biomass were also significantly altered by the treatments. A structural equation model revealed that the responses of Rs to Cd stress, elevated CO2, and N addition were mainly mediated by soil carbon-degrading hydrolytic enzymes and fine root biomass. Overall, our findings indicate that N deposition may exacerbate the negative effect of Cd on Rs in Cd-contaminated forests and benefit soil carbon sequestration in the future at increasing atmospheric CO2 levels.

A New Species

Crocus thracicus is described as a new species from Thrace, the European part of Turkey. The white form of this species was wrongly referred to an albino form of C. chrysanthus by Mathew in the Flora of Turkey. It grows in open stony places and in sparse Quercus sp. and Paliurus spina-christi clearings at elevations between 45–170 m. It is compared with the morphologically similar C. alexandri and C. weldenii. A description, detailed illustrations, photograps of metephase plate, karyotype and idiogram of new species are presented.

Soil respiration can be altered by changing substance supply, respiratory capacity and the demand for the products. We carried out a field experiment in the northeast of China to understand how inoculation with arbuscular mycorrhizal fungi (AMF) alters soil respiration in paddy fields. Soil respiration and factors contributing to it were measured for paddy fields either inoculated or non-inoculated with AMF, with or without fertilization. We found that inoculation increased soil respiration, net photosynthesis of rice leaves, N and P content of rice shoots and the abundance of actinomyces and fungi in rhizosphere; while the negative effect was only observed on root biomass. We also found that fertilization decreased the responses of soil respiration, root biomass and the abundance of bacteria and fungi in rhizosphere to inoculation. However, it decreased the responses of net photosynthesis, shoot biomass and shoot N and P content to inoculation. Conclusively, AMF inoculation promoted soil respiration by enhancing substrate supply, respiratory capacity and the demand for products; while the impacts of inoculation were weakened by fertilization via respiration capacity and the demand for the products.
