Functional group classification and target species selection for Yancheng Nature Reserve, China

Yancheng Nature Reserve in east China is of great importance to the protection of biodiversity. It is a principal refuge for Red-crowned Cranes (Grus japonensis) and many other rare species, an important station for migrant waterfowls in the Asian Pacific, and a captive breeding base for Milu (Elaphurus davidianus). However, since the late 1980s, serious losses of biodiversity have been emerging in the protected area. In this study, to value objectively and improve management of the Yancheng Nature Reserve, a new approach for conservation management is proposed by virtue of the theories of self-organizing systems, functional group classification and target species selection. According to this approach, biological components in Yancheng Nature Reserve are classified into 10 supporting functional groups, eight target functional groups and 11 subordinate functional groups. Eight target species were selected from those target functional groups, i.e., G. japonensis, E. davidianus, Hydropotes inermis, Larus saundersi, Centropus toulou, Felis bengalensis, Paradoxornis heudei, and Platalea minor. Past observations in Yancheng Nature Reserve illustrate that the new approach is feasible, and this new approach will also benefit the management of the nature reserve.

Habitat Assessment for Giant Pandas in the Qinling Mountain Region of China

ABSTRACT Because habitat loss and fragmentation threaten giant pandas (Ailuropoda melanoleuca), habitat protection and restoration are important conservation measures for this endangered species. However, distribution and value of potential habitat to giant pandas on a regional scale are not fully known. Therefore, we identified and ranked giant panda habitat in Foping Nature Reserve, Guanyinshan Nature Reserve, and adjacent areas in the Qinling Mountains of China. We used Mahalanobis distance and 11 digital habitat layers to develop a multivariate habitat signature associated with 247 surveyed giant panda locations, which we then applied to the study region. We identified approximately 128 km²of giant panda habitat in Foping Nature Reserve (43.6% of the reserve) and 49 km²in Guanyinshan Nature Reserve (33.6% of the reserve). We defined core habitat areas by incorporating a minimum patch-size criterion (5.5 km²) based on home-range size. Percentage of core habitat area was higher in Foping Nature Reserve (41.8% of the reserve) than Guanyinshan Nature Reserve (26.3% of the reserve). Within the larger analysis region, Foping Nature Reserve contained 32.7% of all core habitat areas we identified, indicating regional importance of the reserve. We observed a negative relationship between distribution of core areas and presence of roads and small villages. Protection of giant panda habitat at lower elevations and improvement of habitat linkages among core habitat areas are important in a regional approach to giant panda conservation.     

Female Reproductive Parameters of Tana River Yellow Baboons

We describe the female reproductive parameters of yellow baboons at the Tana River National Primate Reserve, Kenya. We present data on menarche, cycle length, pregnancy, birth, postpartum amenorrhea, interbirth interval, and infant survival. We also briefly compare our data to those reported for yellow baboon females at the Amboseli Reserve, Kenya. Our results indicate statistically significant differences in some of these reproductive parameters between the two sites.     

广东翁源青云山自然保护区森林群落优势树种的生态位特征

为探讨广东翁源青云山自然保护区植被的生境适应性和竞争机制,对青云山自然保护区森林群落优势树种的生态位特征进行了分析。结果表明,群落优势种的重要值之和为49.01,其中杉木（Cunninghamia lanceolata）的重要值最大,毛竹（Phyllostachys edulis）的变异系数最大。优势种的Levins和Shannon生态位宽度较为一致,罗浮柿（Diospyros morrisiana）、栲（Castanopsis fargesii）、木荷（Schima superba）、鼠刺（Itea chinensis）和罗浮锥（C.faberi）的生态位宽度较大,而毛竹、杉木、黧蒴锥（C.fissa）和华润楠（Machilus chinensis）的生态位宽度相对较窄。所有物种对间的生态位重叠度和生态位相似性较小,表明共存物种的种间竞争不激烈,因而群落处于相对稳定的状态。生态位宽度与重要值的关系不显著,而与重要值变异系数呈显著的负相关关系,表明重要值变异系数是影响生态位宽度的重要因素。这为青云山自然保护区森林资源的保护和管理提供重要的科学依据。

Southernmost distribution limit for endangered Peladillas (Aplochiton taeniatus) and non-native coho salmon (Oncorhynchus kisutch) coexisting within the Cape Horn biosphere reserve,Chile

The Cape Horn Biosphere Reserve, one of the last wild areas of the planet, is not exempt from the pressures of global change, such as non-native species introductions. During 2018 and 2019 we studied the Róbalo river basin in order to update the diversity and distribution of fishes. Here, we report for the first time the native and endangered “Peladillas” Aplochiton taeniatus and the non-native coho salmon Oncorhynchus kisutch. The coexistence of native and non-native fishes poses a challenge for the management and conservation of aquatic biota from the Cape Horn Biosphere Reserve.     

Maximum Sizes of Some Species of Fish in the Far East State Marine Reserve, Peter the Great Bay, Sea of Japan

The results of 6-year-long observations on the size of some fish species of the Far East State Marine Reserve (Peter the Great Bay, Sea of Japan) suggest that resident fishes attain maximum size in the waters of the reserve. Compared to previously known sizes of fish, record values were found for the white-spotted greenling Hexagrammos stelleri (540 mm), the frog sculpin Myoxocephalus stelleri (490 mm), the snowy sculpin M. brandti (418 mm); the fringed blenny Chirolophis japonicus (520 mm), and some other fishes. These data confirm the opinion that the Marine Reserve waters are the reservation of the genofond of the inhabiting fish.     

Polystomatidae (Monogenea) of southern African Anura: Polystoma claudecombesi n. sp. parasitic in Rana angolensis Bocage

Polystoma claudecombesi is described as a new species of the Polystomatidae (Monogenea) parasitic in the urinary bladder of the anuran host Rana angolensis. This parasite was collected at three localities in South Africa, namely Vernon Crookes Nature Reserve in Natal province, Witsieshoek Mountain Resort in the north-eastern Orange Free State and Bovenste Oog in the province of Transvaal. It is the largest African polystome described to date. Prevalence at Vernon Crookes Nature Reserve was 4.0% and 2.7% in two successive years, with a mean intensity of 1.0 (n=25 and 36, respectively). One of the two R. angolensis from Witsieshoek was infected with 5 parasites. The diversity and distribution of southern African polystomes is also discussed.

Face to face with the woolly spider monkey. Review of faces in the forest: The Endangered Muriqui Monkeys of Brazil,by Karen B. Strier. New York,Oxford University Press,Inc., 1992, 138 pp, $49.50

During an intertroop encounter, an infanticide was observed in a population of ringtailed lemurs (Lemur catta) at Berenty Reserve, Madagascar. The killer was a male that had not been previously observed to mate with any females in the infant's troop. This observation, combined with other observations of infanticidal behavior by males at Berenty Reserve and the Duke University Primate Center, is consistent with the hypothesis that infanticide is a reproductive tactic for some male ringtailed lemurs. © 1994 Wiley-Liss, Inc.     

Length‐length and length‐weight relationships for four fish species from Naolihe National Nature Reserve,Heilongjiang, China

In this study the length‐length and length‐weight relationships for four fish species from Naolihe National Nature Reserve in China belonging to three families and four genera were analyzed. They are Perccottus glenii Dybowski, 1877; Rhodeus sericeus Pallas, 1776; Cobitis lutheri Rendahl, 1935; and Misgurnus mohoity Dybowski, 1869. Fish samples were collected in May 2017 from Naolihe National Nature Reserve by fish catching cage (31*41 cm caliber, 16 m length, 3–5 mm mesh diameter), and identified as to species in the laboratory according to S. Q. Zhu (Synopsis of freshwater fishes of China, Jiangsu Science and Technology Publishing House, Nanjing, China, 1995).     

Identification of environmental plasmid-bearing Vibrio species isolated from polluted and pristine marine reserves of Hong Kong, and resistance to antibiotics and mercury

Fifty environmental isolates of Vibrio species were isolated from water samples of Mai Po Nature Reserve and the Cape d’Aguilar Marine Reserve in Hong Kong and screened for the presence of plasmid. Mai Po is a wastewater-impacted area while the Cape d’Aguilar Marine Reserve is pristine natural marine water. Plasmid was found in Vibrio isolates from both sites at similar frequencies and each site showed distinctive plasmid profiles. These plasmid-bearing Vibrio isolates were identified as different species of the Vibrio genus by both biochemical test and subsequently full-length 16S rRNA sequences. Antibiotic resistance test showed that all these plasmid-bearing Vibrio isolates showed multiple resistance to 21 antibiotics tested. In addition, selective isolates also showed tolerance to 10 M Hg²⁺ in culture medium and they generally harbored large plasmid(s) (>‰30 kb). Our results show that the high frequency of plasmid in Vibrio species of both polluted and pristine environments may be ecologically important to the survival of these bacteria in the environment. The specific functioning of the cryptic plasmids remains the focus of current investigations.     

Can the use of natural biostimulants be a potential means of phytoremediating contaminated soils from goldmines in South Africa?

Biostimulants offer great potential in improving phytoremediation of contaminated soils. In the current greenhouse-based study, Brassica juncea seedlings grown on soils collected from Krugersdorp Goldmine and the adjourning areas (a Game Reserve and private farmland) were supplemented with different biostimulants (Kelpak® = KEL, vermicompost leachate = VCL, smoke-water = SW). Indole-3-butyric acid (IBA) was included in the study for comparative purposes because these biostimulants are known to enhance rooting. Prior to the pot trial, concentrations of elements in the three soil types were determined using Inductively Coupled Plasma-Optical Emission Spectroscopy. Plants were harvested after 105 days and the growth and concentrations of elements in the various plant organs were determined. TheB. juncea seedlings with and without biostimulants did not survive when growing in soil from the Krugersdorp Goldmine. The Game Reserve and private farmland soils supplemented with KEL produced the highest plant biomass and the lowest accumulation of metals in the organs of B. juncea. High concentrations (>13 000 mg kg^?1) of zinc and aluminium were quantified in the roots of IBA-supplemented soils from the Game Reserve. Generally, IBA and SW enhanced the phytoremediation of B. juncea due to elevated levels of elements that accumulated in their different organs.     

Breeding biology and seasonal abundance of Lappet-faced Vultures Torgos tracheliotus in western Saudi Arabia

Lappet-faced Vultures Torgos tracheliotus utilizing a 2200-km², fenced, protected area in western Saudi Arabia were studied over 4 years. Numbers fluctuated seasonally from minima of c. 30 individuals in the spring to maxima of 160 birds in the autumn. All birds foraged predominantly on domestic livestock carrion outside the Reserve. In each year, up to 17 pairs attempted to breed, with 81% of pairs laying eggs, typically in large Maerua crassifolia trees. In all, 81% of the eggs hatched and 85% of nestlings fledged. Most eggs were laid in December, when mean daily air temperatures were lowest, and young usually fledged c. 180 days later. Overall, 56% of nesting attempts fledged young. Juvenile mortality over the first 3 months after fledging was at least 17%. The numbers and proportion of breeders appeared to be stable, but it is not known whether the establishment of the Reserve concentrated the nesting and roosting of vultures in the area or has attracted birds from elsewhere. Breeding success was higher than in most well-studied African populations and probably those nesting elsewhere in Arabia. Four pairs reared 52% of the fledglings observed in the Reserve over 4 years. The Saudi Arabian Lappet-faced Vultures probably belong to the subspecies negevensis and, because of the extinction of this subspecies in the wild in Israel, the well-being of the Saudi Arabian population is critical to the subspecies' conservation.

Parmi les espbces recensks se trouvaient l'Aigle Sexpentaire de Madagascar Eutriorchis astur et le Newtonie de Fanovana Newtonia fdnovanae, tous deux trouves uniquement dans le site situk a la plus basse altitude.     

Evidence for a Recent Henslow's Sparrow Population Increase in Illinois

Abstract: The Henslow's sparrow (Ammodramus henslowii) is a species of high conservation concern due to long-term population declines and a small global population. Habitat loss is considered to be the most likely cause of Henslow's sparrow declines and the recent establishment of large acreages of undisturbed grasslands through the Conservation Reserve Program is considered to have the potential to benefit populations. I used data from Illinois' Spring Bird Count to estimate recent population trends and examine the association that changes in land-use, especially the establishment of Conservation Reserve Program lands, have had on local Henslow's sparrow population trends. My analysis shows that Henslow's sparrow populations have increased substantially within Illinois, USA over the last 10 years and that this population increase strongly coincides with the establishment of >400,000 ha of grasslands within the state by the Conservation Reserve Program. New rules allowing for managed haying and grazing on Conservation Reserve Program grasslands have the potential to reduce the suitability of program fields for this species and, thus, Henslow's sparrow use of program fields should be monitored as the new rules are implemented.
