Abstract The present work assesses the diversity of pollinators in a pea ( Pisum sativum L ) crop from La Overuela (Valladolid, Spain). It is based on samplings carried out in 2008 that combined visual observations and the use of sweeping nets. The field work identified a total of 317 individuals, belonging to 25 genera and 42 species. The most abundant species discovered are Eucera codinai Dusmet and Alonso, 1926 with 46.68% and  Xylocopa violacea  (L. 1758) with 19.87% of abundance. Moreover, the phenological analysis clearly confirms there is a relationship between plant growth stages and the presence of pollinators in a crop commonly considered to be self-pollinating. This demonstrates the important role that pollinators play in pea cross-pollination.

  Abstract Go to The interaction between humans and animals is an important element for the survival of humanity. There is frequent interaction between the  Hippopotamus amphibius  and people at Bui National Park, yet the socio-zoological value and conservation perception of  Hippopotamus amphibius  among local people is limited in literature. The study employed informal and semi-structured interviews to ascertain ethnozoological information in the Ghana Bui enclave. The study revealed that the  Hippopotamus amphibius  is well-known, and different body parts, including the dung, bones, liver, skin, teeth, meat, and tongue, are used for various purposes serving as food, medicine, and use for religious purposes, ceremonies, spiritual protection and tourism. The most common use of hippos is for food and medicine. A wide range of the zootherapeutic use of hippos includes the treatment of measles, body swellings, rheumatism, mental instability, asthma, diab...

Opinion World population expansion and climate change have posed greater challenges to food production. It is believed that food production would need to be raised by 100-110% in 2050, higher than the 70% expected in the current scenario [1]. As a result, more herbicides and fertilizers are being utilized in contemporary agriculture to improve crop yields. However, the frequent application of these agrochemicals offers several ecological losses and health risks [2]. The severe ecological losses and inefficiency in food production continue to confound efforts in achieving and maintaining food security [3]. Therefore, developing and exploring smart and eco-friendly strategies without compromising crop yields and food security is an exciting new futuristic research direction in this area. To date, various advanced techniques have been developed, including nanotechnology and slow and controlled release technology [4]. Smart nanoparticle (NPs) based technologies are grea...

 The Economic Valuation of Ecosystem Services: A Path Leading to a Synthesis between Anthropocentrism and Ecocentrism by Giovanni Barozzi Reggiani in Biodiversity Online J_ Journal of Biodiversity Opinion A lot has been written about the economic valuation of natural resources and of the socalled ecosystem services: from the works of [1-4] to nowadays, a large number of papers and books have been published on that specific topic. As it is well known, ecosystem services are defined as the benefits people obtain, directly or indirectly, from ecosystems (and, more specifically, from ecosystem functions) (see the Millennium Ecosystem Assessment, MEA, 2005). That concept refers to an anthropocentric vision of the world: the environment is considered as an element which can contribute to human well-being [5]; at the same time, I believe that it is hard to deny that an ecosystem-based approach to the definition of public policies-concerning the protection of the ...
