Non-target species interaction with sodium fluoroacetate (1080) meat bait for controlling feral pigs (Sus scrofa)

Fresh meat baits containing sodium fluoroacetate (1080) are widely used for controlling feral pigs in Queensland, but there is a potential poisoning risk to non-target species. This study investigated the non-target species interactions with meat bait by comparing the time until first approach, investigation, sample and consumption, and whether dying bait green would reduce interactions. A trial assessing species interactions with undyed bait was completed at Culgoa Floodplain National Park, Queensland. Meat baits were monitored for 79 consecutive days with camera traps. Of 40 baits, 100% were approached, 35% investigated (moved) and 25% sampled, and 25% consumed. Monitors approached (P < 0.05) and investigated (P < 0.05) the bait more rapidly than pigs or birds, but the median time until first sampling was not significantly different (P > 0.05), and did not consume any entire bait. A trial was conducted at Whetstone State Forest, southern Queensland, with green-dyed and undyed baits monitored for eight consecutive days with cameras. Of 60 baits, 92% were approached and also investigated by one or more non-target species. Most (85%) were sampled and 57% were consumed, with monitors having slightly more interaction with undyed baits than with green-dyed baits. Mean time until first approach and sample differed significantly between species groups (P = 0.038 and 0.007 respectively) with birds approaching sooner (P < 0.05) and monitors sampling later (P < 0.05) than other (unknown) species (P > 0.05). Undyed bait was sampled earlier (mean 2.19 days) than green-dyed bait (2.7 days) (P = 0.003). Data from the two trials demonstrate that many non-target species regularly visit and sample baits. The use of green-dyed baits may help reduce non-target uptake, but testing is required to determine the effect on attractiveness to feral pigs. Further research is recommended to quantify the benefits of potential strategies to reduce the non-target uptake of meat baits to help improve the availability of bait to feral pigs.

Contesting Forests and Power : Dispute, Violence and Negotiations

"Contesting Forests and Power; Dispute, Violence and Negotiations in Central Java" is an ethnographic analysis of an ongoing forest land dispute and its negotiations in an upland forest village in the district of Wonosobo, Central Java. Rather than focusing only on the village site, this ethnography of global connections explores the inequalities of power in different negotiation arenas and how these power relations have had an effect on the dispute and efforts made to settle it. Today, national and transnational connections have an effect on how land disputes develop. This study argues that different cosmological and cultural orientations influence how the dispute and its negotiations have evolved. It draws its theoretical framework from legal and political anthropology by looking at the position of law in society, exploring state formation processes and issues of power. The dispute over state forest land is about a struggle over sovereignty which involves violence on the parts of different parties who maintain that they have a legitimate right to the state forest land. This anthropological study argues that this dispute and its negotiations reflect the plurality of laws in Java and Indonesia in a complex way. It shows that this dispute over forests and land in Java has deep historical roots that were revealed as the conflict emerged. Understanding land disputes in Java is important because of the enormous potential for conflicts over land and other natural resources throughout Indonesia. After the fall of President Suharto in 1998, disputes over access to state forest land emerged as a problem all over upland Java. As the New Order came to an end, forest cover on state forest lands in the Wonosobo district was largely destroyed. Disputes over access to land and forests took another turn after the decentralization effort in 1999, suggesting that decentralization does not necessarily contribute to the protection of forests. The dispute examined here is not unique, but, rather, this study attempts to shed light on forest-related conflicts all around upland Indonesia and on the ways in which differential power relations are reflected in these conflicts and the negotiation processes meant to resolve them.

Traditionally Protected Forests´ Role within Transforming Natural Resource Management Regimes in Taita Hills, Kenya

In Taita Hills, south-eastern Kenya, remnants of indigenous mountain rainforests play a crucial role as water towers and socio-cultural sites. They are pressurized due to poverty, shortage of cultivable land and the fading of traditional knowledge. This study examines the traditional ecological knowledge of Taitas and the ways it may be applied within transforming natural resource management regimes. I have analyzed some justifications for and hindrances to ethnodevelopment and participatory forest management in light of recently renewed Kenyan forest policies. Mixed methods were applied by combining an ethnographic approach with participatory GIS. I learned about traditionally protected forests and their ecological and cultural status through a seek out the expert method and with remote sensing data and tools. My informants were: 107 household interviewees, 257 focus group participants, 73 key informants and 87 common informants in participatory mapping. Religious leaders and state officials shared their knowledge for this study. I have gained a better understanding of the traditionally protected forests and sites through examining their ecological characteristics and relation to social dynamics, by evaluating their strengths and hindrances as sites for conservation of cultural and biological diversity. My results show that, these sites are important components of a complex socio-ecological system, which has symbolical status and sacred and mystical elements within it, that contributes to the connectivity of remnant forests in the agroforestry dominated landscape. Altogether, 255 plant species and 220 uses were recognized by the tradition experts, whereas 161 species with 108 beneficial uses were listed by farmers. Out of the traditionally protected forests studied 47 % were on private land and 23% on community land, leaving 9% within state forest reserves. A paradigm shift in conservation is needed; the conservation area approach is not functional for private lands or areas trusted upon communities. The role of traditionally protected forests in community-based forest management is, however, paradoxal, since communal approaches suggests equal participation of people, whereas management of these sites has traditionally been the duty of solely accredited experts in the village. As modernization has gathered pace such experts have become fewer. Sacredness clearly contributes but, it does not equal conservation. Various social, political and economic arrangements further affect the integrity of traditionally protected forests and sites, control of witchcraft being one of them. My results suggest that the Taita have a rich traditional ecological knowledge base, which should be more determinately integrated into the natural resource management planning processes.

The Asian elephants Elephas maximus of Cat Tien National Park, Vietnam: status and conservation of a vanishing population

This study updates the status and conservation of the Endangered Asian elephant Elephas maximus in Cat Tien National Park, Vietnam. Line transect indirect surveys, block surveys for elephant signs, village surveys of elephant-human conflict incidents, guard-post surveys for records of sightings, and surveys of elephant food plants were undertaken during the dry and wet seasons of 2001. A minimum of 11 elephants and a maximum of 15-17 elephants was estimated for c. 500 km2 of the Park and its vicinity. The elephants are largely confined to the southern boundary of the Park and make extensive use of the adjoining La Nga State Forest Enterprises. During the dry season the elephants depend on at least 26 species of wild and cultivated plants, chiefly the fruits of cashew. Most of the villages surveyed reported some elephant-human conflict. Two adult male elephants seem to cover a large area to raid crops, whereas the family groups restrict themselves to a few villages; overall, the conflict is not serious. Since 2001 there have been no reports of any deaths or births of elephants in the Park. We make recommendations for habitat protection and management, increasing the viability of the small population, reducing elephant-human conflicts, and improving the chances of survival of the declining elephants of this Park. The Government has now approved an Action Plan for Urgent Conservation Areas in Vietnam that calls for the establishment of three elephant conservation areas in the country, including Cat Tien National Park.

Hidatidose policística no norte do Brasil: abordagem parasitológica e histopatológica de pacas e casos humanos

A hidatidose policística é uma zoonose causada pelo cestóide Echinococcus vogeli, amplamente distribuído no norte do Brasil. Os hospedeiros definitivos são Speothos venaticus (cachorro-vinagre) e Canis familiaris (cães domésticos), enquanto Agouti paca (paca) é hospedeiro intermediário. Tanto as pacas quanto o homem (hospedeiro acidental) desenvolvem a forma larvar (metacestóide), principalmente na superfície e no interior do fígado. Esta tese tem como objetivo geral estudar as características parasitológicas e histopatológicas de metacestóides de E. vogeli, originários de pacas e humanos da região norte do Brasil, visto o conhecimento insuficiente ou mesmo o seu desconhecimento. Os fígados e mesentérios foram obtidos de oito pacientes com hidatidose policística durante ato cirúrgico na Fundação Hospital Estadual do Acre. Pacas foram capturadas no Município de Bujari, Floresta Estadual do Antimary, Acre. Durante a necropsia das pacas, foram observadas lesões macroscópicas (massas esbranquiçadas ou amareladas, semelhantes a bolhas na superfície dos fígados). Para a análise parasitológica foram aplicadas as microscopias de luz, contraste interferencial de Normaski (DIC) e varredura laser confocal. A análise morfométrica foi realizada com o auxílio do Programa Image Pro Plus Media Cybernetics. Os órgãos de pacas e humanos foram submetidos à análise histopatológica. Os pequenos e grandes ganchos rostelares apresentaram polimorfismo morfológico, enquanto a organização dos protoescólices acompanhou o padrão descrito para Echinococcus sp. Todas as pacas apresentavam cistos hepáticos, porém em apenas duas encontramos líquido hidático, comprovados pela presença dos ganchos e protoescólices. A análise histopatológica dos tecidos hepáticos das pacas confirmou a hidatidose policística e evidenciou, pela presença de agrupamentos de ovos, a coinfecção com Calodium hepaticum. As características morfológicas dos ganchos rostelares dos casos humanos não diferiram do descrito para as pacas, entretanto, os ganchos dos helmintos provenientes do fígado foram maiores que os mesentéricos. Já em relação aos protoescólices, os mesentéricos foram maiores do que os hepáticos. Cistos mesentéricos e hepáticos apresentaram protoescólices em diferentes estágios de desenvolvimento, com coroas de ganchos, formadas por grandes e pequenos ganchos, e dois pares de ventosas, além dos corpúsculos calcários. Os cistos hepáticos apresentaram as três membranas características (adventícia, anista e germinativa), enquanto os cistos mesentéricos não apresentaram a membrana adventícia, sendo a anista aquela que mais se destacou neste órgão. No mesentério, as células mononucleares foram os principais constituintes do infiltrado leucocitário, cuja intensidade foi relacionada à capacidade proliferativa da membrana germinativa. Além de cistos hepáticos típicos de fase crônica, dependendo da resposta inflamatória, foram observados cistos na fase aguda e sub-aguda. Foi encontrado um caso de coinfecção com vírus (HIV, HCB e HCV) e outro com envolvimento da vesícula biliar. Em suma, confirma-se hidatidose policística em pacas no Acre e são apresentados novos casos de infecção humana no Acre e Amazonas. Pela primeira vez, é demonstrado polimorfismo, padrão diferente de desenvolvimento dos cistos de acordo com o órgão, coinfecção e envolvimento da vesícula biliar

Dispersal and recruitment of juvenile Red-capped Robins, Petroica goodenovii

Data on the dispersal and recruitment of juvenile birds following fledging are largely unreported for Australian birds. In this study, we investigated the short-distance dispersal of a sample of colour-banded, juvenile Red-capped Robins, Petroica goodenovii, in Terrick Terrick National Park, Victoria, Australia. Of 67 colour-banded juvenile birds that successfully reached independence during the 2000–01 breeding season, eight were recruited into the study area or adjacent areas for the following breeding season. A ninth bird was resighted in Gunbower State Forest, 36 km from where it was banded. This is the furthest recorded dispersal movement of a Red-capped Robin. Of 59 colour-banded juvenile birds that reached independence during the 2001–02 season, four remained within the study area for the remainder of the breeding season, but these birds were not present in the study area during the following breeding season. Juvenile birds that successfully reached independence and dispersed were heavier as nestlings, when controlled for age and date, than birds that disappeared (assumed dead) before reaching independence. Estimates of Red-capped Robin abundances within Terrick Terrick National Park were greater than those of nearby eucalypt woodlands, suggesting that the White Cypress-pine, Callitris glaucophylla, woodlands within the park offer good-quality habitat for Red-capped Robins and may be saturated with breeding territories. Thus, juveniles may be forced to establish breeding territories far from their natal territories. These results are discussed in relation to avenues for further research on juvenile dispersal in Australian birds and their conservation implications.

Ecology of Powerful Owls (Ninox strenua) in contrasting habitats of the Yarra Valley Corridor, Victoria, Australia

In this research I investigated ecological attributes of Powerful Owls (Ninox strenua) in a continuum of habitats throughout the Yarra Valley corridor of Victoria, Australia. These habitats ranged from a highly urbanized parkland (the Yarra Valley Metropolitan Park) to a relatively undisturbed closed forest (Toolangi State Forest). Different aspects of the owls' ecology were investigated at six sites to determine whether their behaviour changed when they occupied habitats with different levels of urbanization and disturbance. The ecological attributes investigated were habitat utilization and habitat requirements (for both roosting and nesting), adult behaviour (through radio-tracking), juvenile behaviour and dispersal (through radio tracking), diet (through analysing regurgitated food pellets) and breeding success rates. A number of methods were used to capture adult Powerful Owls. These are described and their effectiveness discussed. The types of radio-transmitters and colour bands used for identification of owls are also described. The results showed that Powerful Owls are present and successfully breed in urban and suburban areas and that they can tolerate moderate levels of disturbance. However, Powerful Owls do require sites with high prey densities, roost trees and trees with suitable breeding hollows. In comparison with Powerful Owls living elsewhere in forests, the urban owls displayed higher tolerance levels to disturbance and were less selective in terms of habitat usage and diet. Home range sizes of urban Powerful Owls also appeared much smaller than those of the forest-dwelling Powerful Owls. This is probably due to the high prey densities in the urban areas. The ecology of the Powerful Owl is compared with that of two owl species from North America, the Northern Spotted Owl (Strix occidentalis caurind) and the Great Horned Owl (Bubo virginianus). In particular, I compared the similarities and differences in habitat requirements and breeding successes in different habitats for the three species. Overall, it would appear that urban areas can support Powerful Owls providing some old-growth trees are maintained to provide nest hollows. Implications for the long-term management of Powerful Owls in urban areas are also discussed.

A colourful addition to the spider fauna of Victoria : the peacock spider Maratus splendens (Rainbow, 1896) (Araneae: Salticidae)

Jumping spiders belonging to the endemic Australian genus Maratus are popularly referred to as peacock spiders, so called for the remarkable courtship displays of the often brightly coloured males. Several Maratus splendens were found in Buldah State Forest, East Gippsland in 2011 and 2013, representing the first records of this species from Victoria. Until recently, this species was known only from around Sydney. While a degree of caution should be exercised whenever implying possible new distributional records based on single localities, it is considered most likely that this discovery represents a genuine expansion in the known range of Maratus splendens. Details are also provided for a previously unpublished record from the central coast of New South Wales.

Habitat Suitability Analysis of the Critically Endangered Florida Panther

The purpose of this study was to conduct a habitat suitability analysis of the critically endangered Florida panther (Felis concolor coryi) in Florida. We gathered land cover, population and road data from the Florida Geographic Data Library and performed map algebra using ESRI’s ArcGIS to compile a suitable habitat map. We found that there is 20381.7 km² of highly suitable habitat and 557124.4 km² of less desirable but usable habitat for the Florida panther. The highest concentration of highly suitable habitat is in Big Cypress National Park, with smaller patches in Tates Hell State Forest and along the southeast portion of the Panhandle. Due to extensive fragmentation, however, and without establishment of habitat linkages to the existing southern population, there is little chance of survival of additional panther populations in much of northern Florida.

Propriedades físicas dos lenhos juvenil e adulto de Pinus elliottii Engelm var. elliottii e de Eucalyptus grandis Hill ex Maiden

The juvenile wood presents great difference in its anatomical and physical properties in relation to the mature wood. That heterogeneity of the wood causes a series of upset for the processing industry. The present research had as objective the study of the physical properties of the juvenile and mature wood of Pinus elliottii Engelm var. elliottii, with 25 years of age and of Eucalyptus grandis Hill ex Maiden, with 30 years of age, coming from the Experimental Station of Itapetininga and State Forest of Santa Barbara, belonging to the Forest Institute of the state of São Paulo. From both species there were taken from radial boards, specimens with dimensions of 20x30x50 mm, for the determination of density, swelling and swelling coefficient of the juvenile and mature wood. The results of the species showed that the mature compared with the juvenile wood presented: (1) an increase in the values of the basic density, at 0% and at 12% of moisture content and of the volumetric, radial and tangential swelling at 12% moisture content and maximum coefficient of radial and tangential swelling; (2) a reduction in the values of longitudinal swelling at 12% and maximum and of the longitudinal swelling coefficient.

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Caracterização dos elementos físicos da bacia do córrego Santo Antônio (Rio Claro/SP)

O objetivo desta pesquisa foi caracterizar os elementos físicos da bacia do córrego Santo Antônio, buscando compreender a influência que a área de entorno dessa bacia exerce sobre a Floresta Estadual Edmundo Navarro de Andrade (FEENA). Para isto, foram elaboradas as cartas geomorfológica e de uso do solo, além da compilação de dados geológicos, pedológicos e climáticos. Essa influência foi avaliada em termos da dinâmica de remobilização de materiais provenientes das nascentes, que não pertencem a FEENA, e que se constituem, portanto, em área de uso agrícola. A análise das características físicas indicou que essa área é susceptível a ação dos processos morfogenéticos e que estes foram intensificados e acelerados pelo uso do solo ao redor das nascentes. Verifica-se, assim, a necessidade de se reavaliar esse uso e de se fiscalizar o cumprimento da própria legislação ambiental, no que se refere ao uso e ocupação do território, em fundos de vale.
