Pollinator Habitat Availability And Diversity In Various Tropical Agroforestry Management Systems Of Coffea Arabica In Santa Clara, Chiriqui, Julia Brokaw
Independent Study Project (ISP) Collection
Habitat loss due to increasing agricultural intensification and chemical use may result in the loss of biodiversity of bee species. This has implications for global economies and food security for people world wide. Focusing on coffee cultivation, an important cash crop in the tropics, this study aims to understand the availability for pollinator habitat resources in a management gradient from shade-grown coffee agroforestry to conventional farming systems that employ both organic and non-organic management practices. I examined the influence of farming and land-use practices on the availability and quality of habitats for social and solitary bee species through observations of …

Investigations Of Phytoplankton Diversity In Chesapeake Bay, Todd Arthur Egerton
Biological Sciences Theses & Dissertations
Characterizing the diversity of a community in relation to environmental conditions and ecosystem functions are core concepts in ecology. While decades of research have led to a growing comprehension of diversity in many ecosystems, our understanding in aquatic habitats and microbial organisms remains relatively limited. Phytoplankton represent a diverse and important group that contribute approximately half of global primary productivity and are intrinsically connected to changing environmental conditions, especially in systems as dynamic as estuaries. To better understand the ecological processes governing phytoplankton composition and diversity, spatial and temporal patterns of environmental parameters and their relation to the algal community …

The First Molecular Phylogeny Of Buthidae (Scorpiones), Victor Fet, Benjamin Gantenbein, Alexander Gromov, Graeme Lowe, Wilson R. Lourenço
Euscorpius
The first partial phylogeny of family Buthidae (17 genera) is presented, based on molecular data (16S rRNA mitochondrial DNA). The strong support for a monophyletic Old World group of 13 genera (mainly Palearctic desert forms) is demonstrated, while representative genera from Madagascar (Grosphus) and Southeast Asia (Lychas) group outside, as well as New World genera Centruroides and Rhopalurus. A very strong support is observed for the first time for three groups of Old World genera: (a) Compsobuthus, Mesobuthus, Liobuthus, Kraepelinia; (b) Hottentotta, Buthacus; (c) Orthochirus, Anomalobuthus.

Morphology Analysis Supports Presence Of More Than One Species In The “Euscorpius Carpathicus” Complex (Scorpiones: Euscorpiidae), Victor Fet, Michael E. Soleglad
Euscorpius
We investigate a number of scorpion populations from southern and central Europe, commonly classified under a “catch-all” name of Euscorpius carpathicus (L., 1767). This species includes a high number of described subspecies but its composition is not resolved. The detailed morphology analysis in the present paper includes a number of new characters, in particular individually mapped external patellar accessory trichobothria. It suggests that several clearly separated lineages are present. E. carpathicus (L.) is restricted here to geographically marginal populations from Romania (terra typica), which exhibit loss of one trichobothrium in the patellar series em (= 3). Another lineage (Austria, Croatia, …

Evolution Of Scorpion Orthobothriotaxy: A Cladistic Approach, Michael E. Soleglad, Victor Fet
Euscorpius
This study presents a cladistic analysis of the derivation of orthobothriotaxic patterns in scorpions. Included in this analysis are the original three orthobothriotaxic patterns defined by Vachon (1972, 1974), the pattern of the unique scorpion Pseudochactas ovchinnikovi Gromov, 1998, and two trichobothrial patterns of fossil scorpions, the Upper Carboniferous palaeopisthacanthids and the Lower Cretaceous archaeobuthids. An overview of all fossil scorpion material where trichobothria are reported is presented in detail. The approach used in this analysis is to model the existence of an individual trichobothrium, adopting the ‘absence of’, ‘petite size’ and ‘full size’ as incremental stages of a trichobothrium’s …

Contributions To Scorpion Systematics. I. On Recent Changes In High-Level Taxonomy, Victor Fet, Michael E. Soleglad
Euscorpius
Prendini & Wheeler (2005) criticized the methods of phylogenetic analyses by Soleglad, Fet, and their coauthors, and executed an unprecedented taxonomic action: without analyzing any of these taxa, they performed a wholesale synonymization of four parvorders, eight superfamilies, one family, 11 subfamilies, eight tribes, two subtribes, and three genera (in total, 37 taxa) of scorpions, and made other taxonomic changes. No alternative new classification has been proposed (instead, they revert to a previous classification), and no results of original work on this subject by Prendini & Wheeler (2005) have been presented. Here, we reverse all taxonomic changes performed by Prendini …

Euscorpius
The relict, phylogenetically important scorpion genus Calchas Birula, 1899 (Iuridae) remained monotypic since its description. Its sole species, Calchas nordmanni Birula, 1899, was known only from northeastern Turkey until Kinzelbach (1980) published first records from southern and southeastern Turkey. A few more localities have been reported from Turkey; the species was also found on two Greek islands, Samos and Megisti. We analyzed significant material (63 specimens, including a previously unpublished large series from Naturhistorisches Museum Wien), and concluded that three distinct, disjunct species exist rather than one widespread species as previously thought. Two new species are described: Calchas birulai sp. …

Euscorpius
Ecological niche modeling has allowed several advances in the process of species delimitation. In the present study, I used this method to evaluate the climatic divergence between two scorpion species, Mesobuthus eupeus and M. phillipsii. The ecological niche models (ENMs) were created based on presence-only data with the maximum entropy method. The created models, results of spatial analysis (PCA and Hotelling discriminant), and an identity test suggested that the divergence between these two species is associated with significant divergence in their ecological niches. The results of this study provide additional support for the taxonomic validity the studied species.

A New Species Of Tityus C. L. Koch, 1836 (Scorpiones: Buthidae) From Dominican Amber, Wilson R. Lourenço
Euscorpius
Tityus azari sp. n., a new species of fossil scorpion belonging to the genus Tityus C. L. Koch, 1836 is described based on a specimen in amber from the Dominican Republic. Although the new species can be associated with the extant fauna of the Neotropical region, it presents some particular morphological features such as the presence of sharp denticles on the edge of pedipalp fingers. Due to the incompleteness of the specimen it cannot be assigned to any precise extant subgenera. Once again, this discovery attests to a considerable degree of diversity in the Dominican amber-producing forests.

Persons As Plants: Ecopsychology And The Return To The Dream Of Nature, Monica Gagliano
Landscapes: the Journal of the International Centre for Landscape and Language
Abstract. In this article, I examine human-plant perceptions and interactions in terms of developing a new perspective on the perception and the actions of people towards plants. By combining my scientific understanding of the biological world and my own experiences working with plant shamans, storytellers and mystics from around the world, I engage with the idea that the hierarchical structure by which Western science defines the variety of life forms as ‘primitive’ or ‘more evolved’ is at the root of the current environmental crisis and I argue that the solution to it rests in a change of this very perspective.

The primary goal in development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the American Burying Beetle (Nicrophorus americanus) as a Tier I at-risk species of high conservation priority. Indeed, the American Burying Beetle (ABB) is a species of conservation need throughout its range. Here, I provide some general management recommendations regarding ABB; however, conservation practitioners will need to use professional judgment for specific management decisions based on objectives, location, and site-specific conditions.
