Diversity and abundance of macrofungi in rubber agroforests in southwestern Nigeria

The mushroom diversity was studied for 14 months in Edo State, southwestern Nigeria. A total of 76 macrofungi tantamount to 333 fruit bodies were encountered, 74% of which were identified and named. The basidiomycetes and members of the family Tricholomataceae were the best represented taxa while species on wood‐based substrates made up 66% of the total mushroom taxa. The monthly mushroom abundance profile, diversity and species richness for each sampled plot correlated with local meteorological factors, age of the sampled sites and distribution of wood‐based substrates. Jaccard, Sorensen and Bray–Curtis similarity index values showed that plots A and D, representing young actively managed and old abandoned rubber tree plantations, respectively, were the most dissimilar in mushroom composition. The hypersensitive response of macrofungal fruit bodies to climate variables qualify mushrooms as veritable biomonitors or bioindicators of climate change. This study supported earlier reports that rubber agroforests are a depauperate pool of utilitarian mushrooms.

Amphibians distribution and habitats in the southwestern region of Saudi Arabia

This study surveyed 205 wetland sites in the Southwestern Saudi Arabia. We found seven species of amphibians (Anura), which belong to four families: Bufonidae; which includes four species, Sclerophrys tihamica; S. Arabica, Duttaphrynus dhufarensis, and Bufotes viridis; Hylidae, represented by only one species, the tree frog Hyla savignyi; Ranidae, which represented by one species, Pelophylax ridibundus and finally the Dicroglossidae, represented by one species, Euphlyctis ehrenbergii. The reasonable amount of rain received in southwest Arabia, and habitat diversity contribute to the relative abundance of amphibians in the region. Five types of wetland habitats were found in the study area. Valley streams, irrigated farms, seasonal ponds, dam reservoir and lagoons of treated sewage water. The current study revealed the wide spread of amphibians in southwestern Saudi Arabia than what had been reported earlier and confirmed the presence of the Bufotes viridis at three new sites in Asir Heights. It also showed the wide spread of S. arabica in all types of habitats in the southwestern region of Saudi Arabia. Habitat degradation was evident in the region, which might lead to species loss.

Diversity, distribution and biogeography of testate amoebae in China: implications for ecological studies in Asia

Testate amoebae are a group of shelled protozoa that occur in high density populations in wet environments. More than 1900 testate amoebae species or subspecies have been reported in published literature over the last 200 years, from many regions of the world. Testate amoebae are classified as Lobosea or Filosea respectively, according to the presence of lobose or filiform pseudopodia. Testate amoebae have proved an interesting group of indicator organisms in palaeoenvironmental studies and have also been used as bioindicators of human impact on ecosystems. Until recently, the testate amoebae of China were unknown to most western scientists, but our knowledge has improved greatly over the past 20 years. This paper summarizes the testate amoebae research in China along with relevant data from other countries in Asia, and provides the necessary context for future research.

Global diversity and distribution of macrofungi

Data on macrofungal diversity and distribution patterns were compiled for major geographical regions of the world. Macrofungi are defined here to include ascomycetes and basidiomycetes with large, easily observed spore-bearing structures that form above or below ground. Each coauthor either provided data on a particular taxonomic group of macrofungi or information on the macrofungi of a specific geographic area. We then employed a meta-analysis to investigate species overlaps between areas, levels of endemism, centers of diversity, and estimated percent of species known for each taxonomic group for each geographic area and for the combined macrofungal data set. Thus, the study provides both a meta-analysis of current data and a gap assessment to help identify research needs. In all, 21,679 names of macrofungi were compiled. The percentage of unique names for each region ranged from 37% for temperate Asia to 72% for Australasia. Approximately 35,000 macrofungal species were estimated to be “unknown” by the contributing authors. This would give an estimated total of 56,679 macrofungi. Our compiled species list does not include data from most of S.E. Europe, Africa, western Asia, or tropical eastern Asia. Even so, combining our list of names with the estimates from contributing authors is in line with our calculated estimate of between 53,000 and 110,000 macrofungal species derived using plant/macrofungal species ratio data. The estimates developed in this study are consistent with a hypothesis of high overall fungal species diversity.     

北京地区大型真菌多样性分析

为明确北京地区大型真菌资源状况,以中国科学院菌物标本馆馆藏的京区标本和本研究组采自该地区的标本为材料,结合已报道的文献资料,经过对定名标本的物种名称进行系统整理,得到北京地区大型真菌记录867种,隶属于2门20目72科281属,其中食用菌294种,药用菌169种（包含食用兼药用菌69种）,毒菌56种。在全部大型真菌中,蘑菇科Agaricaceae、多孔菌科Polyporaceae、口蘑科Tricholomataceae和红菇科Russulaceae等24科拥有的物种占总物种数量的77.28%,这些科在该地区占有主导地位;红菇属Russula、蘑菇属Agaricus和丝盖伞属Inocybe等50个属的物种占总物种数量的60.21%,具有相对优势。大型真菌区系分布分析的结果表明,北京地区已发现的大型真菌主要为世界广泛分布的属。物种丰富度分析表明采自门头沟区的大型真菌的标本数和物种丰度最高,最能代表北京地区大型真菌物种的多样性;其他地区采集的标本数量显著减少,而且物种数和物种丰度均明显降低;特别是城区和近郊地区,由于适宜栖息地的丧失,大型真菌更是少见。

Lichens of Barla Mountain in Isparta,Turkey: Diversity study and ecological assessment of the area

This study reports on 230 infrageneric lichenized and lichenicolous taxa from Barla Mountain, Isparta, Turkey and assesses the ecological features of the area using the distribution of the lichens in the region and their poleophoby and solar irradiation ecological indicator values. One lichenized fungus, Protoblastenia terricola, and one lichenicolous fungus, Zwackhiomyces dispersus, are recorded as new in Turkey and 194 taxa are reported for the first time from Barla Mountain. After this research, number of the lichenized and lichenicolous fungi taxa of Barla Mountain rose to 241. Based on assessments using the ecological indicator values, the area is dominated by natural or semi-natural and well-preserved habitats.     

Karyotypes and geographical distribution of ricefishes from Yunnan,southwestern China

Morphometric and karyotypic studies were made on two species of ricefishes collected from Yunnan, southwestern China.Oryzias latipes from Yunnan had the same morphological and karyological characteristics asO. latipes collected from eastern China. The Yunnan populations had 2n, 46 chromosomes consisting of 3 metacentric, 8 submetacentric, 2 subtelocentric, and 10 acrocentric pairs, the arm number (NF) being 68 (2n=46, NF=68, 3M+8SM+2ST+10A). The karyotype was characterized by having a “large” metacentric pair and nucleolus organizer regions (NORs) on the short arms of a submetacentric pair.Oryzias minutilius from Yunnan had the same morphological characteristics asO. minuiillus from Thailand and Burma, although the karyotype was different from that collected from Thailand. The Yunnan population had 2n, 42 chromosomes consisting of 21 acrocentric pairs, NF being 42 (2n=42, NF=42, 21A). The karyotype was characterized by having NORs at the telomeric regions of an acrocentric pair.Oryzias latipes occurs widely on the eastern Yunnan Plateau where the climate is temperate or subtropical, whereasO. minutilius is found in Xishiangbanna, the southern low mountain areas of Yunnan, where the climate is tropical.
