Early photographs and historical accounts show northern-range aquatic areas bordered by dense riparian-shrub stands. Browsing impacts were first reported in 1914, followed by heavy impacts, then slight recovery during the elk herd reductions, and then widespread elimination of willow by today, except in exclosures and where wolf populations have scattered elk. Although numerous other causes have been proposed by park investigators, the evidence overwhelmingly points to elk herbivory. Evidence from architectural analysis of cottonwood stands points to tree recruitment prior to 1894, then virtually none from 1894-1962 except for one brief burst in 1934-1951, then some recruitment during the herd reduction, and none since 1974. Riparian fauna such as beaver, white-tailed deer, moose, avifauna, and some insect species have declined as riparian vegetation has been browsed down.Less

This chapter discusses the marine components of mangroves. Mangroves provide marine organisms with both a physical environment and nutrients. Pneumatophores and prop roots greatly expand the surface area available and provide a hard substrate, in contrast to the surrounding mud, while the primary production of mangroves supplies an energy source for many organisms. These marine components include algae, fauna of mangrove roots, invertebrates, molluscs, meiofauna, and fish.Less

Huge numbers of prehistoric vertebrate extinctions and large-scale range contractions have been documented throughout the Holocene. Evidence for direct human involvement in these extinctions and population shifts is not confounded by other factors and remains relatively undisputed. The Holocene has the potential to act as an ideal study system for investigating the long-term dynamics of anthropogenically mediated extinctions at a global scale, but it remains uncertain whether most prehistoric Holocene extinction events occurred as a result of direct overkill or indirect factors such as habitat destruction. This chapter reviews data on global patterns of mammal and bird species extinctions to provide an assessment of patterns of prehistoric human impact across space and time since the end of the last glaciation. Whereas continental mammals and bird extinctions were relatively minor in comparison to Late Pleistocene megafaunal extinctions, insular faunas have experienced massive-scale extinction events of varying complexity over the past few thousand years.Less

Heliodinids are tiny, brightly colored dayflying moths. This book proposes phylogenetic relationships among genera of Heliodinidae using parsimony and character compatibility, and describes and illustrates 45 North and Central species (25 newly named) assigned to five genera (two new, two exhumed from synonymy). Larval host plants are recorded for 33 species (14 newly discovered), about 45% of the known fauna; 90% of these are specialists on Caryophyllales, primarily Nyctaginaceae.Less

This chapter considers the significance of the Ediacaran Fauna. Until the late 1980s, the Ediacaran Fauna were usually thought to represent ancient, primitive animal forms. Debate was sparked when leading paleontologist Dolf Seilacher from Tubingen, Germany, reinterpreted these fossils as something completely different. He argued that, instead of animals, they were long-extinct varieties of living organisms, a result of failed lineages with no successors. The rocks on the Avalon Peninsula of southeastern Newfoundland house the oldest known representatives of the Ediacaran Fauna. These so-called rangeomorphs date back to 575 million ago and appear relatively soon after the end of the Gaskiers glaciation some 580 million years ago. Evidence suggests that Ediacaran Fauna of the Avalon Peninsula emerged into an ocean undergoing oxygenation.Less

Assam forests were often depicted as enchanting forests in Assamese literatures. While the grandiose of the Assam forests were central to Assamese literature, contemporary literature however demystifies these forests and illustrates rapid deforestation and fauna depletion. Over the years the wilderness of the forests were tamed and the jungles were converted into mere forests. These transformations in the forest landscapes were brought about by the petty trades of forest products to blatant commerce in the international business. These practices have an immense impact not only in the landscape of the forests but also in the forest management and in the perception of these jungles. Within the commerce of forestry, several groups emerged, contesting rights over the forest resources. These battles contributed to the deforestation however, along the pandemonium over forest resource, came a new turn wherein the idea of forest conservation and reforestation took the centre stage.Less

Charismatic fauna can play a critical role in how we navigate the challenges of natural resource preservation and conservation. Their highly relatable appeal makes them ideal candidates for conservation campaigns, branding, and marketing, while their easy identification is valuable for ecotourist experiences. The revenue generated from both ecotourism and conservation campaigns (donations indicate a willingness to pay) can help assign a recognized value to our natural world and all its natural capital, making conservation rather than development our economic choice. For many people, the plight of highly recognizable charismatic species embodies the biodiversity crisis, as relying on their appealing faces as proxies for habitat protection makes sense. Their presence has the potential to generate ecotourist dollars that can be used to preserve and protect ecosystems and habitats beyond their own terrains, creating an umbrella effect. The benefit of utilizing charismatic fauna as surrogates for larger ecological issues is how effectively these animals can be used to protect the landscapes and biodiversity of entire ecosystems.Less

By the teens of the 20th century the evidence for a deep human antiquity took yet another turn, with the discovery of human skeletal remains in apparent association with extinct Pleistocene fauna. If that association could be proven, it potentially provided a more precise means of estimating the age of the remains than enclosing gravel or less. But here too there was ambiguity, for the age of Pleistocene faunas was still so little known that when it came to estimating the antiquity of the Vero site championed by Elias Sellards, it was either Early Pleistocene in age according to paleontologist Oliver Hay; Middle to Late Pleistocene by the geologists' reckoning; or Recent according to Hrdlička. The evidence from Vero and the nearby Melbourne site sparked a wide-ranging debates over how to reconcile evidence when disciplines collide, about when modern humans appeared, whether evolutionary rates in humans and non-humans were comparable, about the place of Neanderthals on the human family tree, and especially about whose evidence was superior and therefore trumped all others. Sellards retreated from the fight, but in Hay Holmes and Hrdlička met their match in stubborn self-righteousness. Worse for them, Hay lampooned their views with wicked humor.Less

This chapter analyzes the faunas found in early Miocene Xiejiahe and Sihong fossil localities in eastern China. Most of the fossil mammals from the Shanwang Basin and Sihong region appear in the early and middle Miocene of Europe, suggesting widespread mammalian dispersals between Europe and Asia during the early Neogene and providing a foundation for correlation between faunas of these two continents. After a brief overview of the localities, the chapter proposes a new name, Xiejiahe Fauna, for Shanwang Fauna in order to avoid confusion with the nomenclature of ages (stages) and to allow room for naming new faunas in surrounding regions. It also describes the biochronology of the Xiejiahe Fauna and Sihong Fauna. Within these two faunas, most of the families of small land mammals originated before the Miocene, but most of the genera appear only in the Miocene.Less

The complex evolutionary and biogeographic history of the California marine fish fauna has been amply demonstrated in the preceding chapters. This chapter summarizes the historical origins of the fauna, its present status, and the future of the fauna under a scenario of ongoing and perhaps accelerated climate change. Over the last three decades. the understanding of climate change has grown dramatically based on the impacts of global warming, the distribution and abundance of coastal fish faunas, and other biotic elements. Smaller scale events and episodes in recent millennia, centuries, and decades increasingly mix with anthropogenic influences of the past 150 years to complicate the picture of faunal dynamics as seen at the present time. Predicting the future conditions of the California fish fauna must also take into account the entangling influences of human activities, especially overexploitation.Less

At a time when women could not vote, and very few were involved in the world outside the home, Annie Montague Alexander (1867–1950) was an intrepid explorer, amateur naturalist, skilled markswoman, philanthropist, farmer, and founder and patron of two natural history museums at the University of California, Berkeley. This book presents a luminous portrait of this remarkable woman—a pioneer who helped shape the world of science in California, yet whose name has been little known until now. Alexander's father founded a Hawaiian sugar empire, and his great wealth afforded his adventurous daughter the opportunity to pursue her many interests. The author portrays Alexander as a complex, intelligent, woman who—despite her frail appearance—was determined to achieve something with her life. Along with Louise Kellogg, her partner of forty years, Alexander collected thousands of animal, plant, and fossil specimens throughout western North America. Their collections serve as an invaluable record of the flora and fauna that were beginning to disappear as the West succumbed to spiraling population growth, urbanization, and agricultural development. Today, at least seventeen taxa are named for Alexander, and several others honor Kellogg, who continued to make field trips after Alexander's death. Alexander's dealings with scientists, and her encouragement—and funding—of women to do field research, earned her much admiration, even from those with whom she clashed. Her legacy endures in the fields of zoology and paleontology, and also in the lives of women who seek to follow their own star to the fullest degree possible.Less

This book presents a luminous portrait of this remarkable woman—a pioneer who helped shape the world of science in California, yet whose name has been little known until now. Alexander's father founded a Hawaiian sugar empire, and his great wealth afforded his adventurous daughter the opportunity to pursue her many interests. The author portrays Alexander as a complex, intelligent, woman who—despite her frail appearance—was determined to achieve something with her life. Along with Louise Kellogg, her partner of forty years, Alexander collected thousands of animal, plant, and fossil specimens throughout western North America. Their collections serve as an invaluable record of the flora and fauna that were beginning to disappear as the West succumbed to spiraling population growth, urbanization, and agricultural development. Today, at least seventeen taxa are named for Alexander, and several others honor Kellogg, who continued to make field trips after Alexander's death. Alexander's dealings with scientists, and her encouragement—and funding—of women to do field research, earned her much admiration, even from those with whom she clashed. Her legacy endures in the fields of zoology and paleontology, and also in the lives of women who seek to follow their own star to the fullest degree possible.

The negotiations leading up to the 1982 United Nations Convention on the Law of the Sea (LOSC) focused mainly on the fishery issue inside the 200 nautical mile limit, with the creation of the totally new concept of the exclusive economic zone. This chapter examines the issues raised by the relationship between the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the LOSC with respect to protection of biodiversity and fisheries management. It seems that there is no hard-and-fast rule in contemporary international law regulating the relationship between the different international treaties concerned with the conservation and management of commercially exploited aquatic species. Increased cooperation is needed for states to be able to tackle the problem of overfishing on the high seas.Less

This chapter discusses the events that led to the founding and construction of a Museum of Vertebrate Zoology. Grinnell and Alexander both recognized the fact that the vertebrate fauna in the United States was vanishing, and they immediately acted on Grinnell's desire to found a center of scientific authority on the West Coast. Grinnell proposed to build the museum in his alma mater, Stanford University, but Alexander ultimately decided on the University of California at Berkeley. The chapter includes a section on Alexander's proposal for the museum that she submitted to the president of the university, and the initial stages of the construction for the museum.Less

This book explores the geography, ecology, and antiquity of ‘open ecosystems’, which include grasslands, savannas, and shrublands. They occur in climates that can support closed forest ecosystems and often form mosaics with forest patches. With the aid of remote sensing, it is now clear that open ecosystems are a global phenomenon and occur over vast areas in climates that could also support forests. This book goes beyond regional narratives and seeks general explanations for their existence. It develops the theme of open ecosystems as being widespread and ancient, with a distinct biota from that of closed forests. It examines hypotheses for their maintenance in climate zones favouring the development of forests, including soils hostile for tree growth, fire, and vertebrate herbivory.Less

This guide to the marine fauna of the continental shelf seas of north-west Europe provides dichotomous identification keys for macrobenthic invertebrates and coastal fish. An introduction to the marine environment of the region is followed by a guide to the animal groups covered, and each major taxonomic group is treated, in twelve separate chapters, each commencing with a brief description of the morphological and biological characteristics of the group. Technical terms are defined, with especial reference to their significance in classification and importance for identification. Keys to higher taxonomic categories, where useful, and to families lead to keys for the identification of selected species. Confirmatory diagnoses are given for most families. Short descriptions and notes on occurrence and distribution are provided for each species, and the majority are illustrated by line drawings. Coverage varies from group to group, being fairly comprehensive for conspicuous, well-known animals, such as anthozoans, molluscs, echinoderms, and fish, while the selection of species is smaller for some taxonomically difficult or poorly documented groups, such as sponges and sea squirts. However, where possible, the actual or potential diversity of each group within the region is indicated at family level. This edition incorporates systematic and phylogenetic revisions current at submission. Keys have been reviewed and improved; nomenclature has been updated, and descriptions and distributions have been improved or revised where appropriate. Species additional to those in the first edition include several seen to be more common than previously apparent, and a number of newly arrived exotics.Less
