Offshore Fishes of California

by John E. Fitch

The California angler who pursues his chosen sport in the waters of the blue Pacific is, without a doubt, one of the luckiest fishermen in the world. The more than 1,000 miles of ocean shoreline that extend from San Diego to Crescent City (Mexico to Oregon) offer in combination a greater variety of fish and fish habitat, a more extensive fishing area, a better choice of excellent boat launching sites, and a wider selection of highly skilled sport-fishing boat operators than are to be found along any similar stretch of coast anywhere in the world.

عمدة الطبيب في معرفة النبات

by يحيى مراد

دراسة التراث وتاريخ العلوم عند العرب والمسلمين، أمر لابدّ منه في مرحلة التحوّل التي تمر بها الأمة العربية. ذلك لأن اطلاع أبنائها على المنجزات العلمية التي حققها الأجداد في الماضي، لابدّ أن يكون باعثاً على الثقة في النفوس، وحافزاً لحث الخطى في طريق التقدم العلمي والتقني الذي نسعى لتحقيقه.‏ ومن واجب التراث علينا أن نتصدى بأنفسنا لكشف مكنوناته، ونشر روائعه، وإلقاء الضوء على مدى مساهمته في إغناء المعرفة والعلم خلال قرون عديدة، بعد أن ظل هذا العمل مقتصراً على المستشرقين الذين ينتمون إلى أمم مختلفة.‏ وفي مكتباتنا العربية العامة والخاصة كثير من المخطوطات القيّمة، والكتب النافعة التي لم تدرس حتى الآن، ولاسيّما في موضوع الطب والصيدلة وعلم النبات والتي كان لها سماتها، فأدت دوراً كبيراً في إثراء العلوم وبث روح الحياة. حيث كان يلتقي النبات والدواء في مسيرة واحدة لتأمين الغذاء النافع والدواء الناجع.‏ لقد توافرت للعرب ثروة معرفيّة ولغويّة هائلة حين انصرفوا إلى الطبيعة، كغيرهم من الأمم التي سبقتهم، فوجدوا أن الأرض تزخر بالخيرات، من شجر وعشب وبقل وتابل وغذاء، فانصرفوا إلى "علم الفلاحة" ودراسة النباتات. وألّفوا في ذلك كتباً كثيرة لها أهميتها في ميادين علوم النبات والصيدلة والطب وغيرها.‏ وكانت عنايتهم بأصناف النبات نابعة من حاجتهم إلى الغذاء والدواء معاً. وإلى التطيب بالعطور، وصناعة الصباغة والدباغة، وتركيب المواد الصيدلانية من جذور وقشور وثمار وبذور وأعشاب نباتات مختلفة.‏ وهكذا أصبحت المعاجم العربية، والمؤلفات العلمية، غنية بكم وافر من الأسماء والمصطلحات النباتية، وضمَّت معارف العرب المسلمين القدماء في علمي الطب والنبات. فكانت مصدراً لمن ألف وكتب في المفردات النباتية والغذائية والدوائية. وهي كثيرة العدد نذكر منها: "كتاب النبات" لأبي حنيفة الدينوري(1) ت 282هـ-895م)، وكان من أكثر المعاجم جمعاً للمادة، وأعظمها أثراً في معاجم النبات التي ألفت فيما بعد.‏

The Agri-environment (PDF)

by John Warren Clare Lawson Kenneth Belcher Kenneth Ward Belcher

The application of ecological theory and conservation biology to agricultural ecosystems has become an important and growing research field and undergraduate course component in recent years. This book is both an academic textbook and practical guide to farm conservation, and has evolved from the authors' extensive teaching experience. It covers the ecology of farmed land, how agricultural practices influence the environment, how agriculture has changed over time and how the species that inhabit the agri-environment have adapted. It also covers the history of agricultural policy and subsidies and the development of agri-environment schemes. A number of different farming systems are discussed, as are the difficulties in determining their relative merits. Guidance is offered on how to produce a workable farm conservation plan, and the final chapters look to the future and the development of new, greener farming systems.
