The ghost bat (Macroderma gigas) is listed as Vulnerable in Australia, and is a difficult species to study in the wild. The published literature available on even the most basic aspects of its ecology is limited. This study describes an investigation into the diet of ghost bats occupying the Pilbara region of Western Australia, using identification of dried food remains recovered from beneath roosts in the 1980s and 1990s, and DNA metabarcoding of faecal pellets collected from roost sites during 2011–12. Ghost bat diet in the Pilbara region consists primarily of small mammal and bird species, with a lesser contribution from reptiles (geckoes and skinks) and amphibians. In total, 46 vertebrate taxa were identified, with 32 taxa identified from the dried food remains, and 21 taxa by DNA metabarcoding analysis of the faecal pellets. Only seven of the taxa identified were common to both collection methods, and 32 of those taxa identified represent new prey records for ghost bats in Western Australia, and 19 prey species that had not previously been reported from any other part of Australia. Knowledge of the diet of the ghost bat will provide land managers with important information necessary to ensure the continued survival of this species across its range.

A study of foraging by 10 bird species suggests that selective logging of large Eucalyptus marginata will only have affected Melithreptus lunatus, but that proposed silvicultural treatments, including removal of Banksia grandis, may affect several other bird species.

The use of compulsory arbitration for the determination of the conditions of employment has a long history in Australia. This paper covers the events leading up to the introduction of legislation for conciliation and for the compulsory arbitration of industrial disputes in Western Australia. After two bruising strikes and the experience of successful voluntary arbitration, the union movement came to the view that compulsory arbitration would be to their advantage. The development of political links between the unions and some members of the Legislative Assembly, coupled with certain fortuitous circumstances in the Parliament, resulted in arbitration legislation being passed in 1900—despite the dominance of the political scene by conservative forces and the opposition of the employers. Early experiences with the legislation showed that conciliation was not successful when arbitration was readily available and that the Act was not the answer to all the problems of the trade union movement.

Abstract Chlamydias are obligated intracellular Gram-negative bacteria, considered important zoonotic pathogens, broadly present in several bird species and responsible for economic losses in animal production. We analyzed the presence of Chlamydial species with zoonotic risk in farm animals in a highly biodiverse area and with great human circulation, the Argentine, Brazil and Paraguay tri-border area. We surveyed nine farms in an area and nasally swabbed a total of 62 animals. DNA was extracted and specific PCR was performed to identify chlamydial species. We detected Chlamydia spp . in 6.5% (4/62) of the animals tested, positive samples belonged to cattle and none of them showed symptoms of respiratory disease nor had been diagnose with reproductive diseases. Specific nested PCR confirmed two samples belonged to C. pecorum and two to C. psittaci . We report for the first time Chlamydia circulation with zoonotic risk in the region. Surveys in birds and wild mammals could give a better understanding to know what Chlamydial species are circulating in the wild interface. The zoonotic potential should be taking into account as farm workers and the surrounding population could be silent carriers or have respiratory diseases being underdiagnosed, and therefore should be considered in the differential diagnoses.

Determination of animal power consumption by indirect calorimetry relies upon accurate estimation of the thermal equivalent of oxygen consumed or carbon dioxide produced. This estimate is typically based upon measurement or assumption of the respiratory quotient (RQ), the ratio of CO2 produced to O2 consumed. This ratio is used to indicate the mixture of lipids, carbohydrates and proteins in the metabolic substrate. In this analysis, we report the RQ for two bird species, Passer domesticus and Auriparus flaviceps, under several dietary and fasting regimes. RQ commonly differed substantially from those typically assumed in studies of energy metabolism and often included values below those explainable by current knowledge. Errors that could result from these unexpected RQ values can be large and could present the primary limit to the accuracy of power consumption estimates based upon measurement of carbon dioxide production.

Determination of public transport fares needs to be compared to the value of the Ability to Pay (ATP) and Willingness to Pay (WTP) of Kereta Rel Listrik (KRL) service users to pay a sum of money for the services received. The purpose of this study is to analyze the amount of ATP and WTP value of Green Line KRL services’ users, especially those through the Jurang Mangu Station. Primary research data collection methods through surveys with online questionnaire to respondents who have used the Green Line KRL. The research data obtained will be processed and analyzed to obtain the results of respondents’ characteristics, ATP values, and WTP values. The analysis results on the existing tariffs of KRL Green Line with a base rate of Rp. 3.000,- shows the value of ATP and WTP of Rp. 5.057,- and Rp. 4.825,-. The ATP and WTP values respectively for those going through the Jurang Mangu Station are Rp. 5.167,- and Rp. 4.875,-. The results of this study indicate that the ATP value is lower when compared to the WTP value, but this ATP value is greater than the existing tariff. This data shows that the current tariff is proportional to the service received.ABSTRAKPenetapan tarif angkutan umum perlu dibandingkan nilai Ability to Pay (ATP) dan Willingness to Pay (WTP) pengguna jasa Kereta Rel Listrik (KRL) untuk membayar sejumlah uang demi pelayanan jasa yang diterima.

Wild-type and the morphological mutant kin 241 of Paramecium tetraurelia showed improved orientation away from the centre of gravity (negative gravitaxis) when accelerations were increased from 1 to 7 g. Gravitaxis was more pronounced in the mutant. A correlation between the efficiency of orientation and the applied g value suggests a physical basis for gravitaxis. Transiently enhanced rates of reversal of the swimming direction coincided with transiently enhanced gravitaxis because reversals occurred more often in downward swimmers than in upward swimmers. The results provide evidence of a physiological modulation of gravitaxis by means of the randomizing effect of depolarization-dependent swimming reversals. Gravity bimodally altered propulsion rates of wild-type P. tetraurelia so that sedimentation was partly antagonized in upward and downward swimmers (negative gravikinesis). In the mutant, only increases in propulsion were observed, although the orientation-dependent sensitivity of the gravikinetic response was the same as in the wild-type population. Observed swimming speed and sedimentation rates in the wild-type and mutant cells were linearly related to acceleration, allowing the determination of gravikinesis as a linear (and so far non-saturating) function of gravity.

Are you curious about the remains of an animal you have found? This compilation of the most likely found body parts of animals eaten by raptors will help you identify your discovery. Including over 100 species of bird and mammal prey of raptors such as sparrowhawks, peregrines and hen harriers, this photographic guide highlights the common feathers, fur and other body parts found at raptor nests, roosts, plucking posts and other opportunistic spots. Discovering what raptors eat is an important part of confirming their feeding ecology and how this might change over time, vary on a local level or in response to changing prey populations, as well as dispelling myths and assumptions about what certain raptor species eat. Diet studies are vital for the conservation of raptor species; the more we know about what they need for survival the more we can predict and plan long-term for the protection and survival of raptors that may be vulnerable and in decline. This is the first book to show in detail the actual parts of a bird, mammal or other animal that you are likely to find in a garden, woodland or beneath a raptor roost. As more people take an interest in raptors and watch species such as peregrines via webcams and through watch groups, there is greater opportunity for finding prey remains. This book provides the first and most important step in identifying a prey species.
