Abundance And Distribution Of The Forest Cockroaches In Different Algerian Ecosystems, Zakaria Hedjouli, Wafa Habbachi, Fatiha Masna, Saliha Benhissen, Sarra Habbachi, Abdelmadjid Yagoub Asloum, Abdelkrim Tahraoui
Journal of Bioresource Management
Forests have many insect species that are unique to biodiversity and play a crucial role in the functioning of ecosystems. Forest cockroaches are the best example of forest litter insects, which also help decompose fallen leaves. The composition of the Blattoptera fauna can vary from one region to another, depending on the habitat and numerous biotic and abiotic factors In order to study the diversity, abundance, and distribution of forest cockroaches in different Algeria ecosystems, we have selected four sites from three Wilayas: Senalba (Djelfa), Ain achir (Annaba), Seraidi (Annaba), and Lehnaya (El-taref). These sites are classified into two distinct …

Assessment Of The Ponderosa Woodlands In Nebraska's Wildcat Hills: Implications For Juniperus Encroachment And Management, Allie Victoria Schiltmeyer
Assessment Of The Ponderosa Woodlands In Nebraska's Wildcat Hills: Implications For Juniperus Encroachment And Management, Allie Victoria Schiltmeyer
School of Natural Resources: Dissertations, Theses, and Student Research
Ponderosa pine (Pinus ponderosa) is a dominant tree species across western North America. Its eastern distribution includes three populations in western Nebraska. This study assesses the distribution, structure and age of ponderosa pine woodlands in one of those regions, the Wildcat Hills. The Wildcat Hills have escaped severe wildfires seen in recent decades in other ponderosa pine regions. Nevertheless, the Wildcat Hills woodlands face multiple threats including climate change, wildfire, drought, pine beetles, and invasive species. Key to these threats is the stand structure of pine woodlands, which have increased in density across much of ponderosa pine’s range. …

Flight Activity, Oviposition Pit Distribution, And Emergence Densities Of Monochamus Titillator And M. Carolinensis In The Ozark-St. Francis National Forest In Arkansas, Jake Bodart
Graduate Theses and Dissertations
Monochamus (Coleoptera: Cerambycidae) are a genus of longhorn beetles commonly known as pine sawyers. They have a worldwide distribution coincident with pines (Pinaceae) and are vectors of the pinewood nematode (Bursaphelenchus xylophilus). In the United States, there are eight known Monochamus species and they have a sympatric distribution with at least one other Monochamus species throughout their range. Monochamus are known to attack stressed, dead, and dying conifers especially pines. In the Ozark- St. Francis National Forest in Arkansas, there are two species of pine sawyers and they share this sympatric distribution observed throughout the United States, M. titillator (southern …
Toward An Improved Conceptual Understanding Of North American Tree Species Distributions, Paige E. Copenhaver-Parry
Toward An Improved Conceptual Understanding Of North American Tree Species Distributions, Paige E. Copenhaver-Parry
Faculty Publications - Department of Biological & Molecular Science
Species distributions have often been assumed to represent climatic limitations, yet recent evidence has challenged these assumptions and emphasized the potential importance of biotic interactions, dispersal limitation, and disturbance. Despite significant investigation into these factors, an integrated understanding of where and when they may be important is lacking. Here, we review evidence for the factors underlying the historical and contemporary distributions of North American tree species and argue that a cohesive conceptual framework must be informed by an understanding of species ecological and evolutionary history. We further demonstrate that available evidence offers little indication of a significant, independent influence of …
Microclimate Variation And Epiphyte Distribution In Acer Macrophylum, Jeremy Wood
Microclimate Variation And Epiphyte Distribution In Acer Macrophylum, Jeremy Wood
Summer Research
Habitat heterogeneity plays a key role in supporting biodiversity in both animals and plant life. More diverse environments provide more exploitable niches across gradients in temperature, humidity, light availability, and countless other variables at the landscape and regional scales. In specimens of Acer macrophylum in the Hoh Rainforest, we found significant variation in temperature and relative humidity across particular crown zones, and certain epiphyte species were found to distribute according to such microclimate variation.

Development Of Functional Indices Of Facility Occurrence Towards The Distribution Of Social Services In Lagos Island Nigeria., Augustus O. Atubi
Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria
Proper coordination of transport and public facilities provision is vital to any balanced regional development strategy. The central aim of this study, therefore, is to find out what the relationship is between access to the transport network and the provision of functional indices of facility occurrence towards the distribution of social services in Lagos Island, Nigeria. In particular it seeks to find out areas that have below or above average level of facility occurrences relative to the level of accessibility. However, a pair wise correlation matrix of the eleven (11) variables employed in the index construction was carried out. The …

Confluence Journal of Environmental Studies (CJES), Kogi State University, Nigeria
The spatial distribution of banks in any geographic entity determines the level of accessibility to its services by the public. This study examined the pattern of banks distribution in Ilorin metropolis. Field survey was employed in determining the number of available commercial banks and their respective distances between each other. The spatial analysis technique such as the nearest neighbour analysis as used ascertain the degree of clustering, density and the average distance taken to access these services. The study revealed that about 96% of the total number of banks are situated in the Central Business District which exhibited a very …

Distribution And Habitats Of Forked Aster (Aster Furcatus), A Threatened Wisconsin Plant, Lawrence A. Leitner, James A. Reinartz, Donald H. Les
Distribution And Habitats Of Forked Aster (Aster Furcatus), A Threatened Wisconsin Plant, Lawrence A. Leitner, James A. Reinartz, Donald H. Les
Field Station Bulletins
We describe the locations and habitat characteristics of 10 of the 14 known populations of Aster furcatus in Wisconsin. We were unable to identify any particularly unusual features of A. furcatus habitats which could be related to its rarity. The rarity of forked aster is probably not related to specialized habitats, but is most likely the result of requirements for moderate disturbance, inability to withstand competition, poor reproduction from seed, and low genetic variance.
Tall Shrub Dynamics In Northern Minnesota Aspen And Conifer Forests, J.C. Balogh, D.F. Grigal
Tall Shrub Dynamics In Northern Minnesota Aspen And Conifer Forests, J.C. Balogh, D.F. Grigal
Aspen Bibliography
Tall shrubs are a dynamic component of upland forests in the Lake States (Balogh 1983, Dunn 1986, Ohmann and Ream 1971). They are an integral part of forest element cycles, competitors with overstory for growth and reproduction, essential to post-harvest site stabilization, and a source of wildlife cover and browse (Comerford and White 1977, Dunn 1986, Robinette 1972, Tappeiner 1971).

The Distribution Of Sarracenia Purpurea (Pitcher Plant) In Southeastern Wisconsin Fens: The Influence Of Ph And Nutrients, Teresa A. Golembiewski, Forest Stearns
Field Station Bulletins
Temperature, pH, alkalinity, total-N, total-P, K, Na, Ca and Mg levels were measured in groundwater at the Pickerel Lake and Ottawa Lake calcareous fens and the Cedarburg Bog patterned fen. The two calcareous fens were similar in all chemical characteristics. Alkalinity, pH and Mg were significantly lower in the patterned fen when compared to the calcareous fens, while the other chemical parameters were similar. Each of these southeastern Wisconsin fens supported Sarracenia purpurea (pitcher plant). When the characteristics of the groundwater of the areas that supported S. purpurea were compared with those of areas that did not support S. purpurea, …
