Conservation has long focused on preserving or restoring pristine ecosystems. However, understanding and managing novel ecosystems has grown in importance as they outnumber pristine ecosystems worldwide. While non-native species may be neutral or detrimental in pristine ecosystems, it is possible that even notorious invaders could play beneficial or mixed roles in novel ecosystems. We examined the effects of two long-established non-native species—Philippine deer ( Rusa marianna ) and feral pigs ( Sus scrofa )—in Guam, Micronesia, where native vertebrate frugivores are functionally absent leaving forests devoid of seed dispersers. We compared the roles of deer and pigs on seedling survival, seed dispersal and plant community structure in limestone karst forests. Deer, even at low abundances, had pronounced negative impacts on forest communities by decreasing seedling and vine abundance. By contrast, pigs showed no such relationship. Also, many viable seeds were found in pig scats, whereas few were found in deer scats, suggesting that pigs, but not deer, provide an ecosystem function—seed dispersal—that has been lost from Guam. Our study presents a discrepancy between the roles of two non-native species that are traditionally managed as a single entity, suggesting that ecological function, rather than identity as a non-native, may be more important to consider in managing novel systems.

Because of the increasing number of transgender people requesting speech-language pathology services, because having gender-incongruent voice and communication has major negative impacts on an individual's social participation and well-being, and because voice and communication training is supported by an improving evidence-base, it is becoming more common for universities to include transgender-specific theoretical and clinical components in their speech-language pathology programs. This paper describes the theoretical and clinical education provided to speech-language pathology students at La Trobe University in Australia, with a particular focus on the voice and communication training program offered by the La Trobe Communication Clinic. Further research is required to determine the outcomes of the clinic's training program in terms of student confidence and competence as well as the effectiveness of training for transgender clients.

Introduction: Disaster management is a dynamic, continual, and integrated process as to increase the qualities of the actions which are relevant to the process of observation and analysis of disaster as well as minimalizing the negative impacts, mitigation, readiness, early warning, immediate emergency, rehabilitation and reconstruction. The aim of this research is to analyse theconnection between disaster management and the prevention of community breakdown in order to face a volcanic eruption for every head of household. Method: The design of this research is correlational research with a cross sectional approach. The demographic group that is used for this research is the head of households in Rt 06/Rw 01 dusun Puncu desa Puncu, by using the purposive sampling technique which has been collected from the sampling of the 33 heads of households. Independent variable is the knowledge of disaster management, and the dependent variable is the prevention of community breakdown in the handling of the disaster. The data has been received by using the questionnaire, and the results have been analysed by using spearman rho test. Result:  As according to the statistics test, it is found that p-value= 0,000 on the significant level (α) = 0,05 and r = 0,752. It is concluded that there is a connection between knowledge and the prevention of community breakdown in handling of the volcanic eruption in Rt 06/Rw 01. This research shows that the level of knowledge within the community about disaster management and prevention in handling volcanic eruption has been increasing. Conclution: This is shown by the capability of the community in mitigating the effects of the disaster. It is hoped that the community will further engage in training education and simulation to reduce the negative impacts of a disaster. The location where the participants resideis Kelud Volcano, and it is therefore hoped that the communities are willing to participate in better handling of any disaster by joining the education training and simulation; Kata kunci : Pengetahuan, Manajemen bencana, Prevention.

Bulang districts Batam Islands of  Riau province (Riau Islands), its consists of many islands with as well as having the potential diversity of coastal marine life in particular kinds of macro algae or seaweed. Conducted research aimed to determine the structure of macro- algal communities in the intertidal zone islands. The results of the identification of algal species found 16 species are: the Order of Chlorophyceae as 6 spesies; Order Phaeophyceae as 2 spesies; and Order Rhodophyceae as 8 spesies. The community structure at the five stations showed the highest values were found in the island of dominance Cicir (D ' = 0.79) , uniformity index values on Tengah Island (E ' = 0.99) , while the island Balak had the highest diversity index (H ' = 0.88) , with the abundance patterns of population structure on the island is pretty good Central . Results of correlation analysis of regression between IVI types of algae with the conditions of environmental quality suggests that there is a significance (Fhit ˃ F table and the value of r = > 90 %) between IVI algae Halimeda sp and Cryptarachne polyglandulosa at each station with a temperature parameter surface (⁰C) , depth temperature (⁰C) and pH values. Keywords : Algae, Community Structure, Important Value Index.
