Human-assisted biotic migration is a hallmark of the Anthropocene. Populations introduced outside their native ranges (‘migrant species’) have commonly been viewed as a threat to be addressed with lethal control programs. Israel has a long history of anthropogenic changes, and conservation has typically focused on ameliorating direct human impacts rather than eradicating migrant species. However, this may be changing with the growing influence of invasion biology worldwide. We conducted a review of the diversity, conservation status, and academic attitudes toward Israel’s migrant species (IMS). We identified 199 plants and animals from 85 families that have immigrated into Israel from across the globe, and 122 species from 64 families considered native to Israel that have emigrated to every bioregion and to two oceans, although few species have become cosmopolitan. The conservation status of most immigrant (84.9%) and emigrant (55.7%) species has not been assessed, and even the native ranges of eleven immigrants (5.5%) remains unknown. Of those assessed, 27% of immigrants are threatened or decreasing in their native ranges, and 62% of emigrants are globally decreasing or locally threatened and extinct. After accounting for local extinctions, immigration has increased Israel’s plant and vertebrate richness by 104 species. Israel’s immigrants are increasingly being viewed from an invasion biology perspective, with 76% of studies published in the past decade, reaching over a quarter of local conservation publications. Incorporating principles of compassionate conservation could help foster a more socially acceptable and morally grounded approach to the immigrant wildlife of the Middle East.

Compassionate Conservation seeks to merge the protection of animals and nature for improved conservation outcomes. Although Compassionate Conservation has broad disciplinary scope, its emergence at the interface of animal welfare science and conservation biology remains formative. Translocation biology offers an important opportunity to showcase the compassionate conservation approach because translocations encompass direct care and management of individual animals along with concerns for population and species health. Historically, a one-size-fits-all approach to translocations has proven to be misguided. Current advances in the field offer an important opportunity to apply the methodological focus that animal welfare science has on individuals and social groups for improved conservation outcomes. In particular, the evolutionary and behavioural science insights into the personality of individual animals highlights that the welfare of individual animals and the variation among them are integral to population and species recovery. In a review of translocation biology, animal personality and with the inclusion of a translocation case study, I show that translocation biology offers a clear case for the application of Compassionate Conservation principles.

Coyotes ( Canis latrans ) are native to North America and are frequently seen in and around urbanized areas. As human population grows and urban sprawl encroaches on coyote habitat, human-coyote conflicts increase. Faced with the need to find solutions, policy-makers, and conservationists are challenged with the task of designing coyote management programs that would ensure public safety while conserving the species. The need to consider the welfare of individual animals, as encompassed by the emerging field of Compassionate Conservation, adds an additional challenge. By examining two coyote management programs’ case studies in North America—one in Long Beach, California and another in Oakville, Ontario—the benefits of adopting compassionate solutions are illustrated. As exemplified by Oakville’s strategy, compassionate programs promote the moral treatment of animals while proving to be economically and socially superior to strategies employing lethal measures. Such strategies adopt proactive, rather than reactive responses to human-coyote encounters and invest heavily in public engagement and education. Through the development, implementation, and regulation of non-lethal wildlife management policies, more cities and towns will be able to meet the needs of the stakeholders involved in coyote-human conflict while sparing the life of the animal.

The Near Eastern fire salamander, Salamandra infraimmaculata , is considered an endangered species in Israel and is near-threatened regionally. For 25 years, our laboratory has sought ethical sampling methods to protect individuals and populations of Salamandra . To “mark” individuals for estimating dispersal and population size, we use non-invasive individual-specific markings from photographs of larvae and adults. We demonstrated through mesocosm experiments (which are less mortality-driven than in nature) that exotic Gambusia affinis have extreme negative mortality effects on Salamandra larvae. From a compassionate conservation aspect, G. affinis should not be killed and placed in habitats where amphibians are not in danger and mosquitoes can be controlled. We identified breeding-site characteristics demonstrating that permanent breeding sites support larger adult populations than temporary breeding sites. For population genetics studies, we take minimal sized tail tips from adults (which have no adverse effects) for microsatellite data. For gene expression studies, rather than sacrifice entire bodies, we demonstrated that by taking only small larval tail tips, we could follow gene expression. We additionally demonstrated that tail tip removal does not affect survival, time to or size at metamorphosis. We documented high road kill rates at a specific breeding site. To prevent potential disease spread, we sterilize boots and sampling gear. We use results for implementing or recommending conservation of individuals and populations – e.g., identifying: movement corridors for breeding site dispersal; roadkill hotspots for under-road tunnels; suitable habitat for pool construction for more effective conservation; utilizing population genetics for recommending management units; information on demography and genetic diversity to identify hotspots for conservation; removal of Gambusia for amphibian protection.

Drug lord Pablo Escobar imported 4 Hippopotamuses ( Hippopotamus amphibius ) onto his private estate in Colombia in the 1980s. Since his arrest and assassination, the hippos have escaped the confines of the property and have begun to reproduce in the wild of Colombia. They now number approximately 60 individuals. The presence of such a large, and possibly dangerous, species in a new habitat raises several moral and ecological questions and dilemmas. It is unknown what effect these animals may have on their new environment, or the threat that they pose to the people living near them. In an effort to mitigate possible risks to the environment and local populations the Colombian government initiated an effort to castrate all males in the herd. However, it is unlikely that these efforts will be very effective in curbing the population growth of the animals. South America lost most of its large species of animals during the Quaternary Extinction and it is possible that the hippos are filling a gap that still exists in the ecology of the continent. The rewilding efforts occurring around the world aim to restore and protect natural processes and habitats by introducing (or reintroducing) apex predators or keystone species. Perhaps further research could shed light on possible positive influences that the Hippos have on the South American environment and responsible ways to avoid risks to local populations.

Compassionate conservation is an emerging field in conservation that seeks to integrate animal protection and conservation to achieve either improved conservation outcomes, particularly where conservation priorities and human-wildlife conflict, or the same outcomes, but with less pain and suffering for wildlife. In the Australian Capital Territory ( ACT ), Eastern Grey Kangaroos ( EGK s) are culled to reduce grazing pressure on threatened native grasslands and woodlands. We integrate decision-making criteria about animal protection into planning of wildlife-management to formulate a compassionate conservation management case study. The management criteria include a series of guiding questions: Is management necessary? Will intervention (management of EGK s) achieve the desired conservation outcomes? And, if intervention is necessary, is killing necessary? We found that kangaroos can be managed without culling. The conflict between conservation goals and kangaroo abundance is likely to be accentuated during extended drought. In the short-term, methods for improving rates of habitat recovery can include fencing of threatened grassland communities and reduction of kangaroo density via translocation. Human activity must also be monitored as multiple human-caused biotic and abiotic disturbances are known to have a strong impact on biodiversity of the native grassland habitats. In the medium to long-term, Eastern Grey Kangaroos have the potential for maintaining stable populations, and their herbivory is necessary for grassland function and nutrient cycling. Finally, we suggest that compassionate conservation and adaptive management can work well together as social values shift towards greater emphasis on animal protection.

Climate change is likely to alter the relative abundances of plant functional groups and the interactions between plants and soil microbes that maintain alpine meadow ecosystems. However, little is known about how warming-induced alterations to aboveground biomass (AGB) affect soil nutrients and microbial communities. We investigated plant community characteristics in 2002–2009 and analyzed soil properties and the soil microbial community in 2007–2009 to study the effects of warming in Qinghai Province, China. Sampling involved the use of warmed open top chambers, the monitoring of plant community characteristics, the quantification of total and available amounts of soil nutrients, and the evaluation of microbial community composition using phospholipid fatty acid (PLFA) analysis. Experimental warming initially significantly increased the number of plant functional groups and plant community AGB; however, plant community diversity and species richness decreased. Nevertheless, all these variables stabilize...

Gazella gazella was discovered recently in a restricted area in the Hatay province, Southern Turkey, which constitutes the northern most point of the distribution of this species in the world. To determine the distribution of the population of mountain gazelles in the Hatay region, 17 camera-traps were set along 45 km, on a line from the south to north along the Syrian border. The traps were in the field for about five months from late May to mid-October in 2016. Field observations and conversations with local people, wildlife officers and researchers were performed to gain more information about the habits and distribution of the gazelles. Two isolated sub-populations were found: The northern one in the Kirikhan region; about 520 gazelles in an area of about 100 km 2 , and separated by 18 km to the south, and some 20 gazelles in an area of about 25 km 2 in the Reyhanli region. This southern sub-population was first discovered in this research. Fourteen species of mammals were recorded with photo-traps. Hemiechinus auritus is a new record for the Hatay region. The conservation efforts after the discovery of the northern mountain gazelle sub-population, assisted an increasing trend in its size, and resulted in finding the additional sub-population in the Reyhanli region.

Leaves, stems and roots as the main plant organs have specific functions and together modulate survival, growth and reproduction. The relationships between these organs are high research priority, and there have been many hypotheses about the trade-offs between them. However, the results of these hypotheses are inconsistent and confusing. In this study, we examined 15 core traits of leaves, stems and woody roots of 27 dominant shrub species and further tested the hypotheses about the relationships between these organs. Measurements were made for shrubs across 9 sites including desert, steppe, temperate forest and subtropical forest in Shaanxi Province of China. Many significant correlations of different organ traits were found, e.g. nitrogen and phosphorus content showed a significant positive correlation, either within or across organs. Also, representatives of structural traits (carbon content and dry matter content) and mineral nutrient traits (nitrogen and phosphorus content) showed significant positive correlations among the leaves, stems and roots. The results of this study supported the hypotheses that there were significant correlations between leaf and root and between stem and root. Similarly, we found that trade-off between leaf and stem-plus-root showed a significant correlation. Thus, root traits, which are difficult to measure, are coordinated with those of the leaf and stem. We conclude that the leaf component of shrubs is a good proxy for the whole-plant in studying trade-offs and it could provide a convenient way to understand the whole-plant economic spectrum by focusing on the leaf economic spectrum.

The relationships between these organs are high research priority, and there have been many hypotheses about the trade-offs between them. However, the results of these hypotheses are inconsistent and confusing. In this study, we examined 15 core traits of leaves, stems and woody roots of 27 dominant shrub species and further tested the hypotheses about the relationships between these organs. Measurements were made for shrubs across 9 sites including desert, steppe, temperate forest and subtropical forest in Shaanxi Province of China. Many significant correlations of different organ traits were found, e.g. nitrogen and phosphorus content showed a significant positive correlation, either within or across organs. Also, representatives of structural traits (carbon content and dry matter content) and mineral nutrient traits (nitrogen and phosphorus content) showed significant positive correlations among the leaves, stems and roots. The results of this study supported the hypotheses that there were significant correlations between leaf and root and between stem and root. Similarly, we found that trade-off between leaf and stem-plus-root showed a significant correlation. Thus, root traits, which are difficult to measure, are coordinated with those of the leaf and stem. We conclude that the leaf component of shrubs is a good proxy for the whole-plant in studying trade-offs and it could provide a convenient way to understand the whole-plant economic spectrum by focusing on the leaf economic spectrum.","PeriodicalId":50267,"journal":{"name":"Israel Journal of Ecology & Evolution","volume":"63 1","pages":"25-32"},"PeriodicalIF":1.2,"publicationDate":"2017-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/22244662-06301005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46966698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We reported a study on breeding birds occurring inside an 80 m-deep karst sinkhole, with the characterization of the assemblages recorded along its semi-vertical slopes from the upper edge until the bottom. The internal sides of the sinkhole have been vertically subdivided in four belts about 20 m high. The highest belt (at the upper edge of the cenote) showed the highest values in mean number of bird detections, mean and normalized species richness, and Shannon diversity index. The averaged values of number of detections and species richness significantly differ among belts. Species turnover (Cody’s β-diversity) was maximum between the highest belts. Whittaker plots showed a marked difference among assemblages shaping from broken-stick model to geometric series, and explicited a spatial progressive stress with a disruption in evenness towards the deepest belts. Bird assemblages evidenced a nested subset structure with deeper belts containing successive subsets of the species occurring in the upper belts. We hypothesize that, at least during the daytime in breeding season, the observed non-random distribution of species along the vertical stratification is likely due to (i) the progressive simplification both of the floristic composition and vegetation structure, and (ii) the paucity of sunlight as resources from the upper edge to the inner side of the cenote.
