Abstract. The biomonitoring of atmospheric element deposition often uses a single composite sample to test the local mean lichen elem...
Lichen samples are often hung under tree canopies by transplantation to monitor atmospheric element depositions. However, few studies have examined the effects of canopy (presence or absence) and exposure duration on the element composition of lichen transplants. We transplanted lichen Ramalina sinensis from a remote site to a polluted site of Hebe...
We employed a molecular phylogenetic approach using five markers (ITS, nuSSU, nuLSU, TEF1-α, and RPB2) to assess potential cryptic speciation in foliicolous members of Strigula s.lat. (Strigulaceae), including the recently segregated genera Phylloporis, Puiggariella, Raciborskiella, Racoplaca, and Serusiauxiella, from tropical areas in Asia, with s...
Existing methods can not achieve rapid mass decomposition and multi-element analysis of graphite ore samples. In this study, it is found that molten lithium metaborate can destroy the structure of graphite, causing graphite C to be oxidized and decomposed in an oxygen environment. We have established a method for testing graphite ore samples with l...
[In Chinese with English Abstract] Lichen is a reliable biomonitor for atmospheric element deposition, and its element accumulation ability has differences between species and between individuals. In the lichen biomonitoring studies using in situ specimens, the composite sample is often used to represent the average accumulation level of lichen ele...

Altitude is one of the most important factors influencing lichen biodiversity. Understanding the altitudinal distribution patterns of lichens is the first step towards the effective protection of lichen biodiversity. The lichen genus Peltigera tends to distribute at higher altitudes [(2,022±995)m] with a narrow altitudinal range (68% species occurr...
Effects of mean annual temperature, mean annual highest temperature, mean annual lowest temperature, mean annual relative humidity, mean annual precipitation, mean annual solar radiation hours, mean annual solar radiation percentage and mean annual wind speed on the spatial distribution of the lichen genus Peltigera in China were studied. Twenty si...
The process of 200-year industrialization and global economy has led to an increasing metal pollution in water body, atmosphere and soil environments. The enrichment of metals in Antarctic environments and its potential effects on the ecosystem have evoked increasing interests in atmospheric metal deposition in the related regions. Lichen is one of...
The order Peltigerales is an important group of N-fixing lichens that are essential for ecosystem N cycling in many terrestrial ecosystems. But differences in N-fixing activity among species are not well understood at present. Twelve peltigeralean species collected in different localities and subjected to various desiccation durations, namely Colle...
Leymus chinensis is a dominant species in the Inner Mongolia steppe, northern China. Plant growth in northern China grassland is often limited by low soil nitrogen availability.

I find that literature cited in most of my papers can not be fully collected by ResearchGate. For example, I cited 37 literatures in a recent paper which I uploaded to ReseachGate in form of PDF as a full text of the record. However, only 35 literatures were recognized by ReseachGate, and among which 11 had no links. See the Figure.
It can be seen from the Fig. that the first literature was collected by ResearchGate, with link and information about comment and citations. The second and third literature were not correctly collected by RG. Both literature have no such information and link. I searched both literature and found that they are deposited in the RG systems.
Is this normal? What should I do to facilitate collection of these literature by RG?
The hyperlink "http://www.checklists.de" is now inaccessible to me (in Hebei, China), which presents checklists of lichens in 549 geographic units of the world, as mentioned by Feuerer & Hawksworth (2007)[https://www.researchgate.net/publication/225143440_Biodiversity_of_lichens_including_a_world-wide_analysis_of_checklist_data_based_on_Takhtajan's_floristic_regions] .
Several years ago, I prefer to visit a website ("http://www.lichens.uni-hamburg.de/lichens/portalpages/portalpage_checklists_switch.htm") for checklists of lichens. Lichen checklists can be searched at provincial , regional, national scales. But I found recently that the website is merely accessible for checklists of lichens in some countries and states. Checklists for lichens in Asia (and asian countries) can not be accessible. But I believed that several years ago they were accessible to me.
Does anyone know an alternative for the abovementioned website?
An investigation on element concentration in lichens was conducted in a desertified grassland in Inner Mongolia. Approximately 18 lichen species consisting of more than 100 samples were collected. These species are mainly foliose lichens, corticolous, terricolous and saxicolous. Surrounding surface soil samples and surface rocks were also sampled for comparison.
When plotting ternary diagram I found that the result of Ca-Fe-Ti*8 ternary diagram is weird. See the Figure.
1) Apparently the Fe:Ti ratios in lichens are in the range of those of local surface soil, which may suggest a high level soil/rock particulate entrapment in lichens.
2) All corticolous, terricolous and saxicolous lichen have a tendancy of enriching Ca in the thalli relative to the local rocks and local surface soil, as indicated by the high proportion of Ca in the Ca-Fe-Ti*8 system.
I have no idea why the result 2) occurs. I suggest 2 possible explanations, tentatively.
A. The Ca-riching soil particulates may be heavier than Fe-riching and Ti-riching particulates, or the Ca-containing particulates may be in a size more available to lichens than the Fe- and Ti-rich particulates (as inspired by answers by Paech, see answers).
B. The water solubility is highest for Ca and lowest for Ti. The leaching of Ca into thallus or wet deposition may be responsible for the higher Ca ratio in lichen thalli, at least to a certain extent.
which one is reasonable?
PS. 1 for the ternary diagram: They original data are in ug/g, they has been transformed into % of the sum of the three metals to represent ratios between them, automatically by the software.
PS. 2. Lichens are a group of special plants that depend on atmospheric deposition for nutrients and can enrich metals in amount far beyond the physiological requirement. These organisms have been widely used to monitor air pollution.
PS. 3. The investigated region is caracterized by heavy and frequent sand storm events, especially in spring.
PS. 4. Ti*8 denotes the Ti content used were multiplied by 8, or the data points will be so close to the Ca-Fe line that the Fe-Ti ratios cannot be well presented in the diagram. The Fe:Ti ratios in most of these lichens are 8, very close to those in local surface soils. It was suggested in litterature that this may imply entrapment of soil/rock particulates in lichens.
