旅游活动对卧龙自然保护区社区居民的经济影响

旅游活动是提高自然保护区社区居民收入、缓解保护区与社区矛盾、促进生物多样性保护的重要途径之一.为评价旅游活动对自然保护区社区经济提升的现实效果,以卧龙自然保护区为案例,采用问卷调查的方法,通过分析保护区内旅游从业人员的经济收入、就业机会以及收入分配等,从一定程度上揭示旅游活动对该保护区社区居民的直接经济影响.结果表明,生态旅游可以给保护区的部分居民带来一定的经济收入,但这部分收入总量较低:保护区内的居民多从事一些较简单的旅游相关活动,对技能要求较高的活动则大多由来自保护区外的人员从事:旅游活动带来的经济收入不论是在当地相关从业人员之间还是在当地人与来自保护区外的人员之间的分配都表现出了一定的不公平性,居住位置、启动资金和技术技能是造成这种不公平现象的主要原因.依据以上调查及分析结果,论文提出了开发旅游项目、建立培训机制、设立专项基金以及逐步移民等相应对策.

Sensory,motor, and postganglionic sympathetic neurons forming the ulnar and radial nerves of two macaque species: Macaca nemestrina and Macaca fascicularis

The motor, sensory, and postganglionic sympathetic neurons forming the left ulnar and right radial nerves of long-tailed macaques (Macaca fascicularis) and pigtailed macaques (Macaca nemestrina) were localized by the horseradish peroxidase method of tracing neuronal connections. The ulnar and radial motoneurons formed a longitudinal column of variable extent in the lateral part of the ventral horn. In most animals, the ulnar motoneurons extended between the caudal ends of the C7 and T1 segments; the radial motoneurons extended between the rostral level of the C4 and the middle part of T1 segments. Although there were areas of overlap in the spinal distribution of ulnar and radial motoneurons, the ulnar motoneurons were located more dorsally and dorsolaterally than were the radial motoneurons. In most animals, labelled sensory neurons whose axons run with the ulnar nerve occurred in the C8–T4 dorsal root ganglia, and those whose axons run with the radial nerve occurred in the C5–T3 ganglia. The radial sympathetic neurons were distributed in stellate through T7 paravertebral sympathetic ganglia, and the ulnar sympathetic neurons were distributed in stellate through T4 paravertebral sympathetic ganglia. Though the motor, sensory, and sympathetic neurons forming the ulnar and radial nerves had wide segmental distributions, all showed peak frequencies in two segments. The cross-sectional areas of the motor, sensory, and postganglionic sympathetic neurons forming the radial and ulnar nerves were measured in the animal that showed the greatest amount of labelling for each nerve. The ulnar and radial motoneurons had a similar range of sizes, with cross-sectional areas between 120 and 2,160 μm². Most were smaller than 900 μm². The sensory neurons forming the ulnar and radial nerves also displayed a similar range of sizes, measuring between 120 and 3,360 μm² in cross-sectional area. Most neurons measured between 201 and 800 μm². The ulnar sympathetic neurons measured between 120 and 840 μm², and the radial neurons between 120 and 2,120 μm². In both cases, most neurons measured between 120 and 600 μm². The mean cross-sectional area for the radial sympathetic neurons was, however, larger than that for the ulnar sympathetic neurons.

Differences among three macaque species in responsiveness to an observer

Behavioral responses of experimentally naive captive-born juvenile females of three macaque species (Macaca mulatta, M. radiata, M. fascicularis)to a passive human observer were compared across three periods, beginning approximately 6 weeks after animals were transferred from multianimal groups housed outdoors to individual cages in colony rooms and ending approximately 6 months later. Responsiveness was assessed using eight relatively stereotyped behavior patterns characteristic of this genus. Although overall responsiveness declined across periods in all groups, this measure was consistently highest for M. fascicularis.Patterns were also analyzed as indicative of “fear” or “hostility.” Responses of M. fasciculariswere frequent in both categories, although fear scores exceeded those for hostility. M. mulattascored more frequently as hostile than as fearful. Both fear and hostility scores for M. radiatawere extremely low. The only response shown with more than minimal frequency was lip-smacking, a pattern that is usually construed as an appeasing, submissive, or affiliative display. Differences among species in their responses to the observer are generally consistent with other behavioral and psychophysiological data on the same subjects and with patterns of social interaction between conspecifics.     

Plasma cholesterol levels in free-ranging macaques compared with captive macaques and humans

Plasma total cholesterol in free-ranging Japanese macaques (Macaca fuscata) on Koshima islet and in free-ranging long-tailed macaques (Macaca fascicularis) at Pangandaran in Indonesia was found to occur at very low levels compared with captive macaques and humans. Although total cholesterol levels in captive macaques were lower than humans, differences in HDL cholesterol levels were only small. In both sexes of wild and captive Japanese macaques, total cholesterol levels decreased from birth through to young adulthood but then increased in adult females of the captive group. In contrast, the value for adult females of the wild troop remained at a low level. Low TCH levels in adult females of the wild Japanese macaque troop may be due to a low energy intake and may have caused a delay in the onset of sexual maturation. Plasma TCH levels increased with the addition of 0.1% dietary cholesterol over six weeks in captive long-tailed macaques. That the cholesterol value after six weeks was dependent on cholesterol levels prior to supplementation indicates that captive macaques are slightly saturated with cholesterol.     

The human-ABO blood groups of free-ranging long-tailed macaques (Macaca fascicularis) and parapatric rhesus macaques (M. mulatta) in Thailand

BACKGROUND: Long-tailed and rhesus macaques are widely used in biomedical research; therefore, the known blood group is important. METHODS: The human-type ABO blood group was determined in wild or semi-wild long-tailed and rhesus macaques in Thailand. A total of 729 long-tailed and 160 rhesus macaques from 20 localities were temporarily caught. RESULTS: The frequency profiles of blood groups, calculated by averaging the frequency of each troop in long-tailed and rhesus macaques, were AB > O > B > A at 29.6%, 27.4%, 27.2%, and 15.8%, and B > AB > A > O at 39.6%, 33.4%, 18.2%, and 8.8%, respectively. Irrespective of locality, the frequencies were AB > O > B > A of 29.6%, 28.0%, 24.4%, and 18.0%, and AB > B > A > O of 37.5%, 28.7%, 26.9%, and 6.9%, respectively, for all long-tailed and rhesus macaques. The frequency profile of blood groups in Thai rhesus macaques was somewhat similar to that in the parapatric long-tailed macaques; however, it was different from other rhesus populations where only group B was detected. CONCLUSIONS: Our data support the hypothesis that Indochinese rhesus macaques are hybrids between rhesus and long-tailed macaques in the past.     

Distribution of Grooming Among Adult Females in a Large,Free-Ranging Group of Japanese Macaques

We analyzed grooming episodes recorded among adult females in a large, provisioned, free-ranging group of Japanese macaques (Macaca fuscata) at an individual level. Each female groomed on average 10 of the other 84 females, and 54% of them devoted 50% of their grooming to a single female grooming partner, which indicates that most females had grooming interactions with a relatively small subset of available females. Although 65% of the total grooming bouts were between related females, 25% of females disproportionately groomed unrelated females, 22% groomed related and unrelated females equally, and grooming was kin-biased for the remaining 53%. Moreover, 11 of 16 kin-groups included at least one female that groomed unrelated females significantly more often than related females. In 18% of unrelated dyads, grooming was directed down the hierarchy, in 58%, grooming was well-balanced between the two females, and in the remaining 25%, grooming was directed up the hierarchy. The results indicate that although Japanese macaques are considered a despotic species based on their dominance style, this group included some females that showed egalitarian tendencies, i.e., grooming was directed down the hierarchy or was well-balanced, and was directed toward unrelated females as often as or more often than toward related females. The presence of egalitarian individuals might be important to maintain a well-organized, female-bonded group.

How City Dwellers Affect Their Resource Hinterland

This article links databases on household consumption, industrial production, economic turnover, employment, water use, and greenhouse gas emissions into a spatially explicit model. The causal sequence starts with households demanding a certain consumer basket. This demand requires production in a complex supply-chain network of interdependent industry sectors. Even though the household may be confined to a particular geographical location, say a dwelling in a city, the industries producing the indirect inputs for the commodities that the household demands will be dispersed all over Australia and probably beyond. Industrial production represents local points of economic activity, employment, water use, and emissions that have local economic, social, and environmental impacts. The consumer basket of a typical household is followed in Australia's two largest cities—Sydney and Melbourne—along its upstream supply chains and to numerous production sites within Australia. The spatial spread is described by means of a detailed regional interindustry model. Through industry-specific emissions profiles, industrial production is then translated into local impacts. We show that annually a typical household is responsible for producing approximately 80 tonnes of greenhouse gas emissions, uses around 3 million liters of water, causes about A$140,000 to circulate in the wider economy, and provides labor worth just under three full-time employment-years. We also introduce maps that visually demonstrate how a very localized household affects the environment across an entire continent. Our model is unprecedented in its spatial and sectoral detail, at least for Australia.     

Substance P receptor antagonist reverses intestinal pathophysiological alterations occurring in a novel ex-vivo model of Cryptosporidium parvum infection of intestinal tissues derived from SIV-infected macaques

BACKGROUND: Cryptosporidium infection leads to life-threatening diarrhea in AIDS patients. Pathogenesis of cryptosporidiosis is due to intestinal physiological alterations. We devised an ex-vivo model using ex-vivo Cryptosporidium parvum infection of jejunal tissues derived from SIV-infected macaques and studied the role of substance P (SP) in the pathogenesis of cryptosporidiosis. METHODS: We measured jejunal SP protein levels using ELISA, and electrophysiological alterations using the Ussing chamber technique in an ex vivo model of Cryptosporidium infection. Paraformaldehyde-fixed jejunum from SIV-infected macaques with and without naturally occurring cryptosporidiosis was studied for SP protein expression by immunohistochemistry and fluorescence deconvolution microscopy. RESULTS: Ex-vivo Cryptosporidium-infected tissues and tissues from SIV-infected macaques with naturally occurring cryptosporidiosis demonstrated elevated SP protein levels compared with tissues from SIV-infected animals without ex-vivo C. parvum infection or tissues from SIV-infected animals that have no evidence of cryptosporidiosis. In our ex-vivo model of Cryptosporidium infection, we demonstrated pathophysiological alterations that were blocked by SP-receptor antagonist treatment. CONCLUSIONS: These studies suggest that SP-receptor antagonists could prove useful for treatment of AIDS-related cryptosporidiosis.

Phylogenetic Relationships of the Macaques (Cercopithecidae: Macaca), Inferred from Mitochondrial DNA Sequences

To study the phylogenetic relationships of the macaques, five gene fragments were sequenced from 40 individuals of eight species: Macaca mulatta, M. cyclopis, M. fascicularis, M. arctoides, M. assamensis, M. thibetana, M. silenus, and M. leonina. In addition, sequences of M. sylvanus were obtained from Genbank. A baboon was used as the outgroup. The phylogenetic trees were constructed using maximum-parsimony and Bayesian methods. Because five gene fragments were from the mitochondrial genome and were inherited as a single entity without recombination, we combined the five genes into a single analysis. The parsimony bootstrap proportions we obtained were higher than those from earlier studies based on the combined mtDNA dataset. Excluding M. arctoides, our results are generally consistent with the classification of Delson (1980). Our phylogenetic analyses agree with earlier studies suggesting that the mitochondrial lineages of M. arctoides share a close evolutionary relationship with the mitochondrial lineages of the fascicularis group of macaques (and M. fascicularis, specifically). M. mulatta (with respect to M. cyclopis), M. assamensis assamensis (with respect to M. thibetana), and M. leonina (with respect to M. silenus) are paraphyletic based on our analysis of mitochondrial genes.     

Male Masturbation in Free-Ranging Japanese Macaques

We studied masturbatory behavior of males over a 14-mo period in free-ranging Japanese macaques (Macaca fuscata yakui) on Yakushima island, Japan. We distinguished 2 types: (1) masturbation only and (2) masturbation with final ejaculation. Both types occurred in all 15 adult troop males. We calculated masturbation only as an index (M/h). It occurred over the whole year; however, it was more frequent during the mating than during the non-mating periods. Masturbation with ejaculation was restricted to the mating period. Male mating success correlated positively with social status. Both rate of masturbation only and masturbatory ejaculations increased as male social status and male mating success declined. Lower-ranking males had higher rates of masturbation only, i.e., they spent more time masturbating than higher-ranking males did. Lower-ranking males also had higher proportions of ejaculates for masturbation, while higher-ranking males used most of their ejaculates for mating.     

Population ecology of rhesus monkeys (Macaca mulatta) at Nanwan Nature Reserve,Hainan, China

Rhesus monkeys (Macaca mulatta) at the Nanwan peninsula of Hainan Island, China, have been observed in the field for 25 years, and have been studied intensively for eight years, beginning in 1981. There were about 115 monkeys in 5 natural groups when the Nanwan Reserve was founded in 1965. From 1965 to 1984, the number of groups increased from 5 to 19, and the total population increased from 115 to 930 individuals, an annual population increase of 12.7%. From 1984 to 1987, the population continued a slower rate of increase (8.9%) to approximately 1200 monkeys in 20 groups. The home ranges of each monkey group at Nanwan varied from 0.16 to 0.72 km², with a mean and standard deviation of 0.37 ± 0.18. The size of the home range of the rhesus was affected by the quality of vegetation and rhesus population density. The average birth rate per year was 77.8 ± 13.9%, varying from 53.8% to 100% since 1978. From 1978, the birth rates of two food provisioned groups were higher in alternate years (x? = 91.7%) and lower in intervening years (x? = 68.8%; P = <0.01). A minority (26.5%) of females have given birth at 4 years of age, most at 5 years. The sex ratio of newborns in any one year varied from 0.3 to 3.5 males to females, with a mean and standard error of 1.09 ± 0.37 males to females.
