This article aims i) to review the state of the art in the knowledge of phytosanitary problems reported in the initial stages of cacao cultivation in Ecuador, and ii) to describe the presence of such ...problems in Milagro vivariums. The sources of information were mixed, and these varied according to geographic scale. Information at the country level came from books or articles; in contrast, primary data to identify fungi and information provided by local farmers interviewed to describe local particularities, were used. At the same time, secondary data from undergraduate theses, institutional technical reports and press articles were used. Secondary information, with low visibility but available in digital repositories, contains valuable information for local knowledge. The damages caused by fungi and by arthropods (sensulatupests) were grouped by symptom and causal agent. Symptoms of abiotic origin are also included. The management of insect damage is considered of little importance by nurserymen, unlike those caused by fungi and chromists that constitute the fundamental challenge.
A home aquarium seems a peaceful place. Gazing at its inhabitants as they swim slowly through their small universe is a soothing, even hypnotic, experience. But this seeming tranquillity is only ...surface deep. Like their wild counterparts, these tiny, glittering beings exhibit a wide array of fascinating behaviors. Stéphan Reebs provides a delightfully entertaining, yet scientifically grounded, look at what fishes do and how they do it. From defending their young, to seeking out the perfect sexual partner, to telling time, fishes display a variety of behaviors that may not be readily apparent to the casual observer. Reebs not only describes the behaviors, but also outlines simple experiments that can be performed by observers wishing to learn for themselves just how resourceful—and bizarre—these creatures can be. Fish Behavior in the Aquarium and in the Wild introduces us to damselfishes that sing like birds, elephantfishes that communicate electrically, and sticklebacks that deceive other fish into believing they have found food. Drawing on the experimental evidence behind such intrinsically interesting responses, Reebs demonstrates how science is conducted in the field of animal behavior.

Scores of wild species and ecosystems around the world face a variety of human-caused threats, from habitat destruction and fragmentation to rapid climate change. But there is hope, and it, too, ...comes in a most human form: zoos and aquariums. Gathering a diverse, multi-institutional collection of leading zoo and aquarium scientists as well as historians, philosophers, biologists, and social scientists, The Ark and Beyond traces the history and underscores the present role of these organizations as essential conservation actors. It also offers a framework for their future course, reaffirming that if zoos and aquariums make biodiversity conservation a top priority, these institutions can play a vital role in tackling conservation challenges of global magnitude.While early menageries were anything but the centers of conservation that many zoos are today, a concern with wildlife preservation has been an integral component of the modern, professionally run zoo since the nineteenth century. From captive breeding initiatives to rewilding programs, zoos and aquariums have long been at the cutting edge of research and conservation science, sites of impressive new genetic and reproductive techniques. Today, their efforts reach even further beyond recreation, with educational programs, community-based conservation initiatives, and international, collaborative programs designed to combat species extinction and protect habitats at a range of scales. Addressing related topics as diverse as zoo animal welfare, species reintroductions, amphibian extinctions, and whether zoos can truly be "wild, "this book explores the whole range of research and conservation practices that spring from zoos and aquariums while emphasizing the historical, scientific, and ethical traditions that shape these efforts. Also featuring an inspiring foreword by the late George Rabb, president emeritus of the Chicago Zoological Society / Brookfield Zoo, The Ark and Beyond illuminates these institutions' growing significance to the preservation of global biodiversity in this century.
