The Institute for Applied Ecology (IAE) is a 501(c)(3) nonprofit organization with a mission to conserve native species and habitats through restoration, research, and education. Here, we describe some of our projects working with the Conservation Research Program at IAE. The Conservation Research Program conducts research and montioring of native species and ecosystems in order to determine population trends and effective methods for restoration and management, conducts research on invasive species in order to determine effective control methods, and develops plans for the management and restoration of native ecosystems.

It’s that time of year again! Field season has kicked off for the Conservation Research program at the Institute for Applied Ecology (IAE). This year, our season began at Lower Table Rocks located in southern Oregon near Medford. Warm temperatures, bright blue skies and a plethora of wildflowers welcomed us on all three days.

Since 2006, IAE in partnership with the Medford District BLM has been monitoring the population trends and effects of grazing and recreation on the State Threatened, Federal Species of Concern, Limnanthes pumila ssp. pumila (dwarf wooly meadowfoam).

Permanent plots were distributed in high-and low-traffic areas and in caged and non-caged pairs to study the population trend of Limnanthes pumila ssp. pumila and to determine the factor, if any, which may be affecting the population.

Recently in 2013, five transects were added to Lower Table Rocks to monitor the effects of an emergency fire retardant drop that occurred in July 2010 on plant communities.

  2. الماء هو أساس الكائنات الحية وسبب وجودنا على الأرض. لا حياة بدون ماء. يستخدم الكثير منا دائمًا خزانات المياه للعثور على المياه لحل مشكلة نقص المياه النظيفة.
    تعتبر خزانات المياه من المعدات الأساسية التي يمكن العثور عليها في أي منزل ، ويتم استخدامها للأغراض المنزلية مثل الطهي والشرب والغسيل والاستحمام ، كما تستخدم للأغراض التجارية المختلفة ، وتجدر الإشارة إلى أن خزانات المياه هذه مع مرور الوقت ، الرواسب ، يتراكم الطمي ويصبح غير صالح للاستعمال وقشاري. استعادة إلى حالة أفضل

    مع حلول فصل الصيف نبدأ بالبحث عن أماكن رائعة مجهزة بمكيفات لتلطيف الجو من حولنا سواء في المنزل أو في العمل أو في الاجتماعات التجارية ، والتي تناسب الشركات والمصانع وحتى مراكز التسوق وغيرها ، لكنها كلها متشابه في مبدأ التشغيل الأساسي ، وفكرة عملهم هي نفسها فكرة الثلاجة المنزلية التي تعتمد على غاز الفريون الوسيط المستخدم في نقل الحرارة من الغرفة إلى البيئة الخارجية.

  3. 중국 현지인의 카지노 업체 주식 보유지분을 확대하는 내용도 담겼다. 마카오 정부는 카지노 사업 면허 발급 조건 등도 들여다보겠다고 밝혔다. 마카오에서 영업 중인 카지노 업체 6곳의 면허는 내년 6월 종료된다. 중국 공산당의 입김에서 자유로울 수 없는 마카오 블랙잭 정부가 도박산업 규제를 천명한 것이다. 중국발 '마카오 리스크'에 글로벌 도박업계는 휘청이고 있다.
