植被类型对盐沼湿地空气生境节肢动物功能群的影响

2007年4-11月,在长江口崇明东滩盐沼湿地的芦苇带、海三棱藨草带和互花米草带设置固定样地,每月小潮期对空气生境的节肢动物进行了扫网取样调查。在此基础上,分析研究了盐沼湿地空气生境节肢动物功能群特征以及植被类型的影响,特别是对互花米草的生态效应进行了进一步讨论。调查期间共获得节肢动物标本3778头,分属2纲11目37科49种。根据不同种类的营养特征将其划分为植食性、捕食寄生性和腐食性三大功能群。其中,植食性功能群的种类、数量最为丰富,涉及1纲6目19科25种,物种数占总数的51.0%,个体数占总数的86.2%;捕食寄生性功能群次之,涉及2纲7目15科21种,物种数占总数的42.9%,个体数占总数的7.8%;腐食性功能群种类、数量最少,涉及1纲1目3科3种,物种数占总数的6.1%,个体数占总数的6.0%。不同植被带捕食寄生性功能群与植食性功能群均具有一定的"天敌跟随"特征,但主要表现在物种数上,而在个体数上的对应关系并不明显。不同植被带功能群的组成、多样性及月际变化特征存在一定差异,但是植被类型对功能群的影响并不显著。与已有研究结果不同,研究中外来种互花米草对空气生境的节肢动物并未表现出显著的负面影响,相应节肢动物功能群的物种数、个体数、多样性、月际变化等特征与其他植被带并没有显著差异。就植食性功能群而言,尽管互花米草带植食性功能群的个体数明显低于其它植被带,但是物种数并没有减少,相应的作用机理还有待进一步研究。

Keeping reptiles as pets in Brazil: Ethnozoological and conservation aspects

Regardless of many legal restrictions, the keeping of and trade in reptiles as pets has been increasing in Brazil over the last few years. We present an analysis of the trade and use of reptiles as pets in Brazil and discuss the implications. Data were obtained through semi-structured questionnaires given to 719 owners, who were contacted through reptile-owner groups on the social network Facebook. A total of 69 reptile species were reported as pets in Brazil, of which there were 39 snakes, 17 lizards, 12 chelonians and 1 species of crocodilian. Of the reported species, 46 are native to Brazil and 23 are exotic, including threatened species. Owners were distributed in at least 24 states, with a higher concentration in Southeast Brazil and the Federal District. Owners usually acquire animals through purchase, although prices vary and are high for some species, making reptile ownership more common among high-income individuals. Prices were affected by factors such as beauty, colour pattern, size, sex and even rarity. The keeping of reptiles as pets raises conservation concerns, as the practice directly impacts exploited populations and is a potential introduction pathway for invasive species, including exotic species that have already been recorded in natural habitats in Brazil. A thorough discussion, encompassing various stakeholders — namely, owners, traders and environmental authorities — is much needed, to address management strategies, and propose feasible solutions. Conservation and animal welfare NGOs should also be involved in this process.

Exploited for pets: the harvest and trade of amphibians and reptiles from Indonesian New Guinea

Over-exploitation of wildlife is a significant threat to global biodiversity, but addressing the sustainability of harvests can be difficult when trade is conducted illegally. The wildlife trade is driven chiefly by consumer demand, largely in developed nations (but increasingly in Asia), and more species are traded to meet international demand for pets than for any other purpose. We surveyed traders of amphibians and reptiles in the Indonesian provinces of Maluku, West Papua and Papua between September 2010 and April 2011. We recorded 5,370 individuals representing 52 species collected solely for the pet trade. At least 44?% were either fully protected or had not been allocated a harvest quota, making their harvest and trade illegal. Approximately half were listed within the Convention on International Trade in Endangered Species of Wild Fauna and Flora. Trade operates via a complex chain, with hunters receiving little income compared to middlemen and exporters. Examination of Indonesian harvest quotas for amphibians and reptiles suggests limited knowledge of species distributions, with quotas often set for species in provinces where they do not occur. Illegal trade is due, partly, to an inadequate understanding of the species being traded and is facilitated by poor monitoring and enforcement at key trade hubs. As a first step to combatting illegal trade, and to better understand the effects of harvest on wild populations, we recommend the need for increased monitoring and enforcement, improving the knowledge base of species traded and educating consumers about the effects their demand for pets has on these species.     

Exotic Animal Companions and the Personality of Their Owners

ABSTRACT

The present study explored sex-specific differences in the Big Five factors of personality between different pet ownership groups, in order to understand individual differences in the choice of companion animals. A total of 250 pet owners completed a German version of the NEO-Five Factor Inventory (NEO-FFI). For the first analysis, participants were divided into four broad groups: those owning traditional pets (e.g., cats, dogs), those owning cold-blooded exotic pets, those owning warm-blooded exotic pets, and those not owning animals. For the second analysis, participants were subdivided into nine groups, based on species of animal owned: cats, dogs, birds, fish, reptiles, spider/insect, small mammals, owners of many different animals, and non-owners. In both analyses, separate analyses of variance were applied to the scores of the NEO-FFI scales. Interaction effects between sex and several ownership groups on the traits Openness to Experience and Agreeableness were found in both analyses. Female owners of traditional pets scored, for example, significantly lower on openness to experience than female owners of cold-blooded exotic pets as well as male owners of traditional pets. Furthermore, female owners of cold-blooded exotic pets scored significantly higher on openness to experience than their male counterparts. Regarding agreeableness, male owners of cold-blooded exotic pets scored significantly lower than their female counterparts as well as male owners of traditional pets. These and other results indicate that personality may affect choice of pets—but in different directions for the two sexes.

Not So Cold-blooded: Narcissistic and Borderline Personality Traits Predict Attachment to Traditional and Non-traditional Pets

A growing number of studies have assessed the personality of pet owners. However, although there is a large number of people who own exotic pets, their personalities have seldom been examined. Furthermore, studies of personality of pet owners have focused almost exclusively on typical personality traits, ignoring associations with “dark” traits. Here, we assessed both traditional and some dark personality features in association with pet ownership and attachment in 325 pet owners via an online survey. We predicted that individuals scoring higher on narcissism and borderline personality features would be a) more likely to own exotic pets, and b) less attached to their pets compared with people scoring lower on narcissism and traditional pet owners. Additionally, we theorized that neurotic pet owners would be more attached to their pets compared with less neurotic pet owners. We did not find an association between personality and exotic pet ownership but we found that those high in grandiose narcissism were actually more attached to their traditional pets. Those high in vulnerable narcissism were more attached only if their pets were exotic. Those high in borderline features were less attached to both kinds of pets. Personality assessments including “dark” features of personality may therefore be useful in predicting attachment to pets during the matching process of potential adopters to pets.     

The diversity and origin of exotic ants arriving in New Zealand via human-mediated dispersal

The number of exotic ant species being dispersed to new regions by human transportation and the trade pathways responsible for this are poorly understood. In this study, the taxonomic diversity, trade pathways, and origin of exotic ants intercepted at the New Zealand border were examined for the period 1955–2005. Overall, there were a total 4355 interception records, with 115 species from 52 genera. The 10 most frequently intercepted genera, and the 20 most frequently intercepted species contributed > 90% of all records. Many of the species frequently intercepted are regarded as invasive species, and several are established in New Zealand. The most intercepted species was Pheidole megacephala . Despite a relatively low trade relationship, a high proportion (> 64%) of the exotic ants which were intercepted originated from the Pacific region. However, the majority of species intercepted from the Pacific was exotic to the region (71%), or to a lesser extent, wide-ranging Pacific native species. No endemic species from the Pacific were intercepted. The effectiveness of detecting exotic ant species at the New Zealand border ranged from 48–78% for different trade pathways, indicating a number of species remain undetected. Trade routes associated with specific geographical regions represent a major filter for the arrival of exotic ant species. Despite the importance of the Pacific as a frequent pathway, we suggest that the future establishment of exotic ant species in New Zealand is likely to be mitigated by a renewed focus on trade routes with cool temperate regions, particularly Australia.     

Unintentional introductions of microscopic organisms associated with forest insects

International trade and travel are devastating native flora and fauna in many countries through the intentional and/or unintentional introduction of exotic organisms. Pathway control appears to be particularly effective for microscopic organisms such as mites, nematodes, and fungi that are difficult to see with the naked eye. However, taxonomic and ecological information on such organisms is scarce, sometimes causing time lags or failure in eradication programs. Several groups of mites, nematodes, and fungi commonly share a habitat with insects or use them as dispersal agents (phoresy). Some exotic mites and nematodes are introduced simultaneously with exotic insects, sometimes in wood materials. In Japan, mites, nematodes, and fungi have been collected from lucanid beetles introduced as pets from Southeast Asia. While no lethal nematode species have been collected from lucanid beetles, one hemolymph-sucking mite species, inhabiting the sub-elytral space of its native host, is able to easily switch to the Japanese beetle, Dorcus rectus, killing the insect. Yeasts have also been reported on exotic beetles and laboulbeniomycetes have been found on mites associated with the beetles, although their interactions are unknown. Despite the lack of information available about other mites, nematodes, and fungi associated with intentionally and unintentionally introduced forest insects, our analysis of insect species listed by the International Union for Conservation of Nature suggests that unintentional introductions of the microscopic organisms are quite common as a consequence of the existence of symbiotic relationships such as phoresy and parasitism.     

Captive Reptile Mortality Rates in the Home and Implications for the Wildlife Trade

The trade in wildlife and keeping of exotic pets is subject to varying levels of national and international regulation and is a topic often attracting controversy. Reptiles are popular exotic pets and comprise a substantial component of the live animal trade. High mortality of traded animals raises welfare concerns, and also has implications for conservation if collection from the wild is required to meet demand. Mortality of reptiles can occur at any stage of the trade chain from collector to consumer. However, there is limited information on mortality rates of reptiles across trade chains, particularly amongst final consumers in the home. We investigated mortality rates of reptiles amongst consumers using a specialised technique for asking sensitive questions, additive Randomised Response Technique (aRRT), as well as direct questioning (DQ). Overall, 3.6% of snakes, chelonians and lizards died within one year of acquisition. Boas and pythons had the lowest reported mortality rates of 1.9% and chameleons had the highest at 28.2%. More than 97% of snakes, 87% of lizards and 69% of chelonians acquired by respondents over five years were reported to be captive bred and results suggest that mortality rates may be lowest for captive bred individuals. Estimates of mortality from aRRT and DQ did not differ significantly which is in line with our findings that respondents did not find questions about reptile mortality to be sensitive. This research suggests that captive reptile mortality in the home is rather low, and identifies those taxa where further effort could be made to reduce mortality rates.
