Heat stress in pigs and broilers: role of gut dysbiosis in the impairment of the gut-liver axis and restoration of these effects by probiotics, prebiotics and synbiotics
Heat stress is one of the most challenging stressors for animal production due to high economic losses resulting from impaired animal’s productivity, health and welfare. Despite the fact that all farm animal species are susceptible to heat stress, birds and pigs are particularly sensitive to heat stress due to either lacking or non-functional sweat glands. Convincing evidence in the literature exists that gut dysbiosis, a term used to describe a perturbation of commensal gut microbiota, develops in broilers and pigs under heat stress. Owing to the protective role of commensal bacteria for the gut barrier, gut dysbiosis causes a disruption of the gut barrier leading to endotoxemia, which contributes to the typical characteristics of heat stressed broilers and growing and growing-finishing pigs, such as reduced feed intake, decreased growth and reduced lean carcass weight. A substantial number of studies have shown that feeding of probiotics, prebiotics and synbiotics is an efficacious strategy to protect broilers from heat stress-induced gut barrier disruption through altering the gut microbiota and promoting all decisive structural, biochemical, and immunological elements of the intestinal barrier. In most of the available studies in heat stressed broilers, the alterations of gut microbiota and improvements of gut barrier function induced by feeding of either probiotics, prebiotics or synbiotics were accompanied by an improved productivity, health and/or welfare when compared to non-supplemented broilers exposed to heat stress. These findings indicate that the restoration of gut homeostasis and function is a key target for dietary interventions aiming to provide at least partial protection of broilers from the detrimental impact of heat stress conditions. Despite the fact that the number of studies dealing with the same feeding strategy in heat stressed pigs is limited, the available few studies suggest that feeding of probiotics might also be a suitable approach to enhance productivity, health and welfare in pigs kept under heat stress conditions.

After the grizzly
Thoroughly researched and finely crafted, After the Grizzly traces the history of endangered species and habitat in California, from the time of the Gold Rush to the present. Peter S. Alagona shows how scientists and conservationists came to view the fates of endangered species as inextricable from ecological conditions and human activities in the places where those species lived. Focusing on the stories of four high-profile endangered species—the California condor, desert tortoise, Delta smelt, and San Joaquin kit fox—Alagona offers an absorbing account of how Americans developed a political system capable of producing and sustaining debates in which imperiled species serve as proxies for broader conflicts about the politics of place. The challenge for conservationists in the twenty-first century, this book claims, will be to redefine habitat conservation beyond protected wildlands to build more diverse and sustainable landscapes.

Once upon an elephant
\"From slowing wildfires to planting seeds, one animal is the true superhero that keeps the African savanna in balance. Elephants dig to find salt that other animal lick, their deep footprints collect water for small creatures to drink, and they eat young trees to keep the forest from overtaking the grasslands. In every season, the elephants are there to protect the savanna and its residents - but what would happen if the elephants were only \"once upon a time\"? Read along to discover the important role this keystone species plays in the savanna and explore what would happen if the elephants vanished\"-- Provided by publisher.

Oz Virus Infection in 6 Animal Species, Including Macaques, Bears, and Companion Animals, Japan
Oz virus (OZV) was isolated from an Amblyomma tick in Japan and shown to cause lethal viral myocarditis in humans. However, the natural reservoirs and the distribution of OZV remain unknown. We describe epidemiologic studies conducted by using serum samples collected from mammals throughout Japan. The results showed that 27.5% of wild boars, 56.1% of Sika deer, 19.6% of Japanese macaques, and 51.0% of Asian black bears were positive for virus-neutralizing antibodies against OZV. Approximately 2.8% of dogs and 1.0% of cats also were seropositive. OZV RNA was not detected in any of the examined animal serum samples. Most seropositive animals were distributed in central and western Japan. OZV infects a wide range of animal species, including companion animals and nonhuman primates, and is distributed through central and western Japan, suggesting that further countermeasures are required to prevent this tickborne zoonotic infection.

The animal game : searching for wildness at the American zoo
Over the twentieth century, as wild, tropical animals became familiar attractions in urban American zoos, they became rare in the wild. Americans who made zoos the nation's most popular attractions, developed closer knowledge of tropical animals, especially those from regions colonized by American and European powers. Founded as a living taxonomy of exotic nature, such zoos never achieved the biological and social order their founders so cherished. Workers, animals, and visitors did not behave in ways that matched zoo officials' or founders' visions. Tourists fed the animals, littered, even poached. They sought tales of animal adventure more than science lessons. This book examines the development of zoos and the animal trade that supplied them and how they were both buffeted by global politics, imperialism, revolution, and war. Through the paradox of animals that were endangered yet familiar and entwined in our daily lives, \"Animal Empire\" fosters a dialogue between those charged with conserving the future, those concerned about the effects of the past, and those who gaze at zoo animals and wonder about places, nature, and people they are unlikely ever to see in person. Through zoos, we have learned to look at faraway places, environments, and peoples through the lens of endangered animals. Animal and human lives dramatically collided in the twentieth century and \"Animal Empire\" is a global history as it appeared at the zoo through the life and death of the animals, the keepers who mucked out their cages and reared their young, the traders who captured animals and the imagination of the American public, and the zoo officials who have helped make the idea of animal endangerment a key indictment of our contemporary civilization.-- Provided by publisher

The role of urbanization in facilitating the introduction and establishment of non-native animal species: a comprehensive review
While urbanization is often associated to a loss of biodiversity, non-native animal species are strikingly successful in urban landscapes. As biological invasions are recognized to have detrimental environmental, social and economic impacts, extensive understanding of the interactions between invasive species and the abiotic and biotic environment is necessary for effective prevention and management strategies. However, the mechanisms underlying the success of invasive animals in urban environments are still poorly understood. We provide a first conceptual review of the role of urbanization in the introduction, establishment, and potential spread of non-native animal species. We summarize and discuss the mechanisms enhancing biological invasive potential of non-native animals in urban environments, by both isolating and interlinking the abiotic and biotic drivers involved. Following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA 2020) process, this systematic review covers a total of 124 studies comprehensive of all taxonomic groups, albeit with an evident publication bias for avian and terrestrial invertebrate species (22.1% and 19.8% of literature respectively). High-income regions also represent a larger bulk of the literature (Europe: 26.7%, North America: 23.7%). The most common reported factors facilitating species invasions in urban areas are reduced biotic resistance, and the competitive and urban-compatible ecological and/or behavioural traits of non-native animals allowing urban exploitation and aiding invasion. Finally, we identify important knowledge gaps, such as the scarcity of studies investigating socio-economic spatial patterns in the presence and abundance of invasive species, as well as the adaptive evolution of non-native animal species in urban areas.

Establishment patterns of non-native insects in New Zealand
Insects comprise the majority of non-native animal species established around the world. However, geographic biases in knowledge hamper an overall understanding of biological invasions globally. A dataset of accidentally introduced non-native insect species established in New Zealand was compiled from databases, entomological literature, and examination of specimens in the New Zealand Arthropod Collection. For each non-native species, the first recorded location and first recorded date of detection was obtained. Excluding intentionally introduced species, there are 1477 non-native insect species successfully established in New Zealand across 16 orders, 234 families and 1017 genera. Four orders (Coleoptera, Hemiptera, Hymenoptera and Diptera) contributed 77.5% of all established insect species. Herbivores represented the largest feeding guild (47.7%), comprised of polyphagous (48.3%) or oligophagous (39.7%) species. The majority of these species originated in the Australasian (36.7%) and Palearctic regions (24.8%). Regression trees, using a binary recursive partitioning approach, found the number of international tourist arrivals, exotic vegetation cover, and regional gross domestic product were the main factors explaining spatial patterns of recently established species. Gross domestic product best explained temporal patterns of establishment over the last century. Our findings demonstrate that broad-scale analyses of non-native species have important applications for border biosecurity by providing insight into the extent of invasions. In New Zealand, the current trajectory indicates fewer non-native species are establishing annually, suggesting biosecurity efforts are being effective at reducing rates of establishment.
