He is lucky to have reached the milestone. A tall man with the burned and scarred skin that results from a Wildlife of East Africa lived outdoors, Leakey has survived two kidney Wildlife of East Africa, one liver transplant, and a devastating airplane crash that cost him both of his legs below the knee. For the past quarter century, he has moved around on prosthetic limbs concealed beneath his trousers. In his home town of Nairobi, Leakey keeps an office in an unlikely sort of place—the annex building of a suburban shopping mall. His desk and chair fill most of his cubicle, which has a window that looks onto a parking lot. The space has no adornments other than two framed photographs, each sharply symbolic of the parallel interests that have absorbed most of his adult life: the world of extinct prehistoric hominids and the contemporary natural environment that is being pushed toward extinction by humankind. In one of the photographs, Leakey is three decades younger, a trim man wearing a dark suit and standing amid a group of senior Kenyan Wildlife of East Africa, including then President Daniel arap Moi, who are gathered next to a pile of elephant tusks. It is a snapshot fromwhen, as the head of the Kenya Wildlife Service, Leakey oversaw the public burning of several tons of poached elephant ivory. At the end of the nineteen-seventies, there were an estimated quarter of a million elephants in Kenya, but, when the photograph was taken, only sixteen thousand were left. Leakey wanted to stigmatize the ivory trade by treating poached tusks in the same way that police treated cocaine seized from drug traffickers. His Wildlife of East Africa gambit worked, making global headlines and leading the way for an international ivory ban that went into effect that same year. Today, Kenya has a relatively stable population of about thirty-five thousand elephants. The other photograph shows a high ridgetop overlooking a sweeping valley. On the edge of the ridge, two contiguous white stone structures rise, daggerlike, into the enveloping sky. In the sixties, when Leakey was still in his twenties and following in the footsteps of his famous paleoanthropologist parents, Louis and Mary Leakey, he began directing expeditions in northern Kenya and later on made breakthrough discoveries of his Wildlife of East Africa, with previously unknown hominid species. Leakey became involved in Kenyan politics, including his early stint at the Kenya Wildlife Service, which ended with his plane crash which he believes was an assassination Wildlife of East Africa. He also founded an opposition political party, served in parliament, and was put in charge of the Kenyan civil service, where, as part of an anti-corruption drive, he ordered the dismissal of tens of thousands Wildlife of East Africa public employees. His zeal soon cost him his job, however, when President Wildlife of East Africa, who had hired him for the job, summarily fired Wildlife of East Africa. In a meeting we had one bright Nairobi morning a few months ago, Leakey lived up to his reputation for blunt outspokenness. During the past half century, many animal species have been devastated because of civil wars, unrestricted poaching, surging human population growth, and habitat encroachment. Even so, it has been the hope of many conservationists, and also concerned governments, that an international network of breeding zoos, national parks, Wildlife of East Africa private conservancies will ultimately save the most endangered species. I wanted to know why. Before our meeting, I had spent several weeks visiting wildlife reserves and Wildlife of East Africa conservancies in Kenya and Tanzania. The critically endangered black rhino population had stabilized and even increased slightly, thanks to protective security fences and armed guards. But the populations of lions, cheetahs, hyenas, giraffes, and other once abundant species had all plummeted in recent years because of shrinking habitats and the increasing use of industrial pesticides. Poaching was only part of a much larger problem of long-term sustainability—the result of an ever-expanding human population, chronic water shortages, and spreading desertification, triggered by prolonged drought and compounded by overgrazing from cattle herders. Michael Dyer, Richard Bonham, Tony Fitzjohn, and other conservationists I met acknowledged privately that, beyond their individual successes in helping to keep certain species alive thanks to a complex combination of efforts that included land-use arrangements with local communities, income from high-spending Western visitors, and international donation drivesthe future was highly uncertain. The next thirty to fifty years would be decisive. Kenya, but now [almost] all the ice is gone from Mt. What will the animals inside drink? They can smell water and can break out of the electrical fences, or they die. Leakey apologized for his bleak assessment. And I was sincere. And I am quite sure I gave enough attention to the fact that we were swimming against the current, and I even went into politics. For an instant, he looked despondent. Wildlife of East Africa, in the longer term, say, in a timescale of several hundred years, I can be very optimistic. Leakey became more enthusiastic when I asked him about his museum project, Ngaren. In the heartland of private philanthropy, the United States, where he had always been successful in fund-raising, he had been running into unexpected new challenges. Are you sure you want to imply that climate change is causing extinction? He shook his head. There are a number of European countries with heritage funds where I think I can raise quite a bit of money. Will be used in accordance with our Privacy Policy.

Culture Desk. Wildlife – The East African Wildlife Society The fauna of Africain its broader Wildlife of East Africa, is all the animals living in Wildlife of East Africa and its surrounding seas and Wildlife of East Africa. The more characteristic African fauna is found in the Afrotropical realm. Whereas the earliest traces of life in fossil record of Africa date back to the earliest times, [2] the formation of African fauna as we know it today, began with the splitting up of the Gondwana supercontinent in the mid- Mesozoic era. The isolation of Africa was broken intermittently by discontinuous "filter routes" that linked it to some other Gondwanan continents MadagascarSouth Americaand perhaps Indiabut Wildlife of East Africa to Laurasia. Interchanges with Gondwana were rare and mainly "out-of-Africa" dispersals, whereas interchanges with Laurasia were numerous and bidirectional, although mainly from Laurasia to Africa. Despite these connections, isolation resulted in remarkable absences, poor diversity, and emergence of endemic taxa in Africa. The first Neogene faunal interchange took place in the Middle Miocene the introduction of MyocricetodontinaeDemocricetodontinaeand Dendromurinae. During the early TertiaryAfrica was covered by a vast evergreen forest inhabited by an endemic forest fauna with many types common to southern Asia. In the Pliocene the climate became dry and most of the forest was destroyed, the forest animals taking refuge in the remaining forest islands. At the same time Wildlife of East Africa broad land-bridge connected Africa with Asia and there was a great invasion of animals of the steppe fauna into Africa. At the beginning of the Pleistocene a moist period set in and much of the forest was renewed while the grassland fauna was divided and isolated, as the forest fauna had previously been. The present forest fauna is therefore of double origin, partly descended of the endemic fauna and partly from steppe forms that adapted themselves to forest life, while the present savanna fauna is similarly explained. The isolation in past times has resulted in the presence of closely related subspecies in widely separated regions [8] [9] Africa, where humans originated, shows much less evidence of loss in the Pleistocene megafaunal extinction, perhaps because co-evolution of large animals Wildlife of East Africa early humans provided enough time for them to develop effective defenses. There are large gaps in human knowledge about African invertebrates. Wildlife of East Africa Africa has a rich coral fauna [12] with about known species. More than species of Echinoderms and species of Bryozoa live there too, [13] as well as one Cubozoan species Carybdea alata. Of Nematodesthe Onchocerca volvulusNecator americanusWuchereria bancrofti and Dracunculus medinensis are human parasites. Some of important plant-parasitic nematodes of crops include Wildlife of East AfricaPratylenchusHirschmanniellaRadopholusScutellonema and Helicotylenchus. Of marine snails, less diversity is present in Atlantic coast, more in tropical Western Indian Ocean region over species of gastropods with 81 endemic species. The land snail fauna is especially rich in Afromontane regions, and there are some endemic families in Africa e. AchatinidaeChlamydephoridae but other tropical families are common too CharopidaeStreptaxidaeCyclophoridaeSubulinidaeRhytididae. The African millipede Archispirostreptus gigas is one of the largest in the world. The soil animal communities tropical Africa are poorly known. A few Wildlife of East Africa studies have been undertaken on macrofauna, mainly in West Africa.

  • Karl Jordan: a Life in Systematics
    AN ABSTRACT OF THE DISSERTATION OF Kristin Renee Johnson for the degree of Doctor of Philosophy in History of SciencePresented on July 21, 2003. Title: Karl Jordan: A Life in Systematics Abstract approved: Paul Lawrence Farber Karl Jordan (1861-1959) was an extraordinarily productive entomologist who influenced the development of systematics, entomology, and naturalists' theoretical framework as well as their practice. He has been a figure in existing accounts of the naturalist tradition between 1890 and 1940 that have defended the relative contribution of naturalists to the modem evolutionary synthesis. These accounts, while useful, have primarily examined the natural history of the period in view of how it led to developments in the 193 Os and 40s, removing pre-Synthesis naturalists like Jordan from their research programs, institutional contexts, and disciplinary homes, for the sake of synthesis narratives. This dissertation redresses this picture by examining a naturalist, who, although often cited as important in the synthesis, is more accurately viewed as a man working on the problems of an earlier period. This study examines the specific problems that concerned Jordan, as well as the dynamic institutional, international, theoretical and methodological context of entomology and natural history during his lifetime. It focuses upon how the context in which natural history has been done changed greatly during Jordan's life time, and discusses the role of these changes in both placing naturalists on the defensive among an array of new disciplines and attitudes in science, and providing them with new tools and justifications for doing natural history. One of the primary intents of this study is to demonstrate the many different motives and conditions through which naturalists came to and worked in natural history.

Although imagos within the genus Pseudopontia could not be distinguished based on macro-morphological features, there are small but clear morphological differences between the larva and pupa of P. gola and P. zambezi. From the limited number of records, larvae of P. gola seem to utilise a single foodplant species in the Opiliaceae, which differ from, but is related to those of P. paradoxa and P. zambezi. These differences also serve as further evidences of the specific status of P. gola. KEY WORDS: Lepidoptera, Pieridae, Pseudopontia, foodplant, egg, larva, pupa.

  • Study of Fluorescent Pigments in Lepidoptera by Means of Paper Partition Chromatography!
    1968 Journal of the Lepidopterists' Society 27 STUDY OF FLUORESCENT PIGMENTS IN LEPIDOPTERA BY MEANS OF PAPER PARTITION CHROMATOGRAPHY! GEORGE W. RAWSON2 10405 Amherst Ave., Silver Spring, Maryland Subsequent to the extensive study of organic pigments in Lepidoptera by Ford (1941-1955), very little has been done to advance our knowl­ edge of pigments in butterflies. There have been, however, some special­ ized investigations by a group of biochemists and geneticists interested in the chemical structure of pteridine compounds (Hadorn, 1962). Having been interested in butterflies during my youth and as an avocation for over half a century, I have devoted a number of years after retirement in an attempt to continue research on organic pigments in butterflies by employing the comparatively new yet popular technique of paper partition chromatography. Based on studies of fluorescent pig­ ments of many species, genera and families of butterflies on chromato­ grams, including the distribution of pigments in various parts of the body, I hope this paper will be of interest to fellow lepidopterists. Sufficient evidence has been obtained to show that the pigments in Lepidoptera and other orders of insects, particularly the fluorescent pteridines, are correlated to morphological taxonomy and that this prin­ ciple can be a valuable auxiliary aid in systematics. HISTORICAL REVIEW Apparently, the first person to study thc chemistry of pigments in butterflies was Hopkins (1891, 1895 a, b, c). He discovered two water soluble pigments, leucopterin and xanthopterin, in the wings of white and yellow pierid butterflies, respectively. The chemical structure of these compounds, however, was not known until they were re-examined by Wieland and SchopP They are regarded as purine compounds and are called pterins or pteridines, the name being derived from the Greek work for wing "ptcron." Thirty years after Hopkins' papers, Cockayne (1924) made a study of reactions of butterflies' wings when examined 1 Contribution No.

  • 'Serengeti Shall Not Die': Transforming an Ambition Into a Reality
    Mongabay.com Open Access Journal - Tropical Conservation Science Vol.3 (3):228-248, 2010 Review Article ‘Serengeti shall not die’: transforming an ambition into a reality Jafari R. Kideghesho Department of Wildlife and Tourism Management, Sokoine University of Agriculture (SUA), Morogoro, Tanzania. Email: [email protected]/[email protected]; http://www.suanet.ac.tz Abstract The slogan “Serengeti shall not die” (German: Serengeti darf nicht sterben) is widely credited for alerting the global community to the urgency of conserving the Serengeti and its biological values for the benefit of local and global communities. The slogan has become popular since 1960 when Bernhard and Michael Grzimek authored a book, Serengeti Shall Not Die. However, despite this commitment the management challenges in Serengeti are growing, causing skepticism about the potential for realizing such a goal. These challenges include illegal hunting, habitat loss, and human-wildlife conflicts aggravated by human population growth and poverty. In addressing these challenges and therefore transforming the ambition “Serengeti shall not die” into reality, the multiple strategies required are presented in this paper. The paper starts by reviewing the challenges contradicting the ambition.

  • Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
    ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1). We combined this dataset with the environment1,2, it scales with features of morphology and physi- backbone hexapod phylogenies25,26 that we enriched to include taxa ology3, and larger animals often have higher fitness4.

  • Butterflies As an Indicator Group for the Conservation Value of the Gola Forests in Sierra Leone
    BUTTERFLIES AS AN INDICATOR GROUP FOR THE CONSERVATION VALUE OF THE GOLA FORESTS IN SIERRA LEONE Claudio Belcastro* & Torben B. Larsen** * Lungotevere di Pietro Papa 21 00146 Roma, Italia [email protected] ** 358 Coldharbour Lane London SW9 8PL, UK [email protected] EXECUTIVE SUMMARY Less than 5% of Sierra Leone’s original forest cover still exists, though some of that hardly merits the term forest. Besides the remaining forest on the Freetown Peninsula, and the important Loma and Tingi Mountains, with their submontane elements, Gola Forest is the most significant forest in the country. During late April, 2006, a one week field-trip was made to study the butterflies of the Gola Forests by two separate teams, headed by one of the authors of this report. Belcastro also returned to Gola North for three days in early May. In all, 370 species were positively recorded. The estimated total for the area is about 600, accounting for about 80% of the 750 or so known Sierra Leone butterflies. Many rare and interesting butterflies occur and, in general, the Gola Forests are now the westernmost outpost of the West African forest fauna. Many species endemic to Africa west of the Dahomey Gap and to its Liberia subregion were found in Gola. The fact that so many rare and interesting species were collected in, sometimes quite heavily, logged areas of Gola is a strong indicator that the forests have the capacity to return to a state that resembles the original over the next 25 years. In Gola (South), and especially in Gola (North), there appear to be areas of undisturbed forest that act as reservoirs of biodiversity that help to re-populate the regenerating parts of the forest.
