Spatial distribution of total halogenated organic compounds (TX), adsorbable organic halogens (AOX), and heavy metals in wetland soil irrigated with pulp and paper wastewater

Chemical Speciation & Bioavailability, 2017
Long-term irrigation using wastewater from paper industry may cause seriously problems to the receiving soil. This work surveyed and monitored the soil quality of a wastewater irrigation wetland system in Yancheng City, Jiangsu Province in China in 2014 ...

Changes in phosphorus fractions caused by increased microbial activity in forest soil in a short-term incubation study

Chemical Speciation & Bioavailability, 2018
The effects of adding larch (Larix kaempferi) leaf litter and nitrogen (N) on microbial activity and phosphorus (P) fractions in forest soil were examined in a short-term (28-d) laboratory incubation study.

How facilitation may interfere with ecological speciation [PDF]

, 2012
Compared to the vast literature linking competitive interactions and speciation, attempts to understand the role of facilitation for evolutionary diversification remain scarce.

Computer-augmented modeling studies of Pb(II) and Cd(II) complexes with maleic acid in ethylene glycol–water mixture

Chemical Speciation & Bioavailability, 2016
Chemical speciation of binary complexes of Pb(II) and Cd(II) ions with maleic acid have been studied pH metrically in the concentration range of 0–50% v/v ethylene glycol (EG)–water mixtures maintaining an ionic strength of 0.16 molL−1 at 303 K ...

Speciation by selection: A framework for understanding ecology's role in speciation

Current Zoology, 2013
Speciation research during the last several decades has confirmed that natural selection frequently drives the generation of new species. But how does this process generally unfold in nature?

Co-transport of Pb (II) and Cd (II) in saturated porous media: effects of colloids, flow rate and grain size

Chemical Speciation & Bioavailability, 2018
The transport of Pb(II) or Cd(II) in subsurface has been studied in the literature; however; their co-transport in porous media in presence of colloids has not been clearly understood.

A new species of whipworm from a south american hystricomorph rodent

Memorias do Instituto Oswaldo Cruz, 1990
A new species of whipworm, Trichuris robusti, is described from the cecum and large intestine of rodent, Ctnomys robusti, collected in northern Chile. The nematode shows close affinityto T. bradleyi and T. chilensis, both having been described from Chile

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 ...
