Pollinator Diversity and Abundance in a Pea Crop (Pisum Sativa L.) from Valladolid (Spain)

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.

 Threats to Biodiversity in Australia’s Burdekin River Basin by Eric Wolanski* in  Biodiversity Online Journal The Murray-Darling basin in Australia (Figure 1) is a prime example of a whole river basin suffering from environmental degradation from historical, haphazard developments without integrated planning [1]. A similar scenario is developing for the Burdekin River basin in North Queensland. https://crimsonpublishers.com/boj/fulltext/BOJ.000513.php Biodiversity Online Journal:  Crimson Publishers For more open access journals in  Crimson Publishers Please click on link:   https://crimsonpublishers.com For More Articles on  Biodiversity Online Journal Please click on:  https://crimsonpublishers.com/boj/

Challenging Factors Influencing Biodiversity by Biswas R* in Biodiversity Online Journal Biodiversity , the diverse kinds of living things evolving over the ages and adapting themselves in a particular habitat, plays an inevitable role in equilibrium and sustenance of a natural ecosystem. It also helps build resilience and stabilization of different species of ecosystem. In general, it tries to remain in a balanced state until and unless some perturbations creep in. Whether it is human caused or not, it entirely has severe effect, creating imbalance in the whole process. https://crimsonpublishers.com/boj/fulltext/BOJ.000502.php Biodiversity Online Journal: Crimson Publishers For more open access journals in Crimson Publishers Please click on link: https://crimsonpublishers.com For More Articles on Biodiversity Online Journal Please click on: https://crimsonpublishers.com/boj/

Biodiversity and Biogeography of Three Pseudomonas syringae athovars which Affect Kiwi Fruit Cultivation_Crimson Publishers

Biodiversity and Biogeography of Three Pseudomonas syringae  athovars which Affect Kiwi Fruit Cultivation by Morán FE* in Biodiversity Online Journal Kiwi fruit is an economically important crop in several countries and it can be affected by several bacterial pathogens . Three pathovars of Pseudomonas syringae have been reported affecting kiwi fruit plants :  seudomonas syringae pv. actinidiae causal agent of bacterial canker of kiwi fruit; P. syringae pv. actinidifoliorum, causal agent of leaf spot of kiwi fruit, and P. syringae, pv. syringae causal agent of floral buds necrosis. Since there is a high phenotypic and genetic diversity among strains inside these pathovars here are briefly described the main differences found in the kiwi fruit strains of these three pathovars to help in developing preventive and curative control strategies to efficiently manage the bacterial diseases that affect kiwi fruit. https://crimsonpublishers.com/boj/fulltext/BOJ.000503.php ...
