Alpha Diversity And Species Status Of Uneven Forests In Eco-Zones Of Taraba State, Nigeria, Dau Henry Japheth, Joseph A. Ugbe, Jerry I. Alfa
Alpha Diversity And Species Status Of Uneven Forests In Eco-Zones Of Taraba State, Nigeria, Dau Henry Japheth, Joseph A. Ugbe, Jerry I. Alfa
Journal of Bioresource Management
Alpha diversity indices quantify the uncertainty in predicting the species identity of an individual. Quantitative indices on species composition and distribution are vital to understanding the trend and species status of an ecosystem for conservation management. However, among the forest ecosystems in Taraba state, Bakin Dutse and Wasaji uneven forests are one of the least studied areas, especially in terms of tree species status. This research work aims at assessing alpha diversity and species status of selected uneven forests in Taraba state, Nigeria; to provide baseline knowledge for conservation management. In total, 102 tree species from 74 genera and 41 …
A Preliminary Study On The Small Population Paradigm And Nesting Biology Of Rose-Ringed Parakeets (Psittacula Krameri) In Gujar Khan, Pakistan, Muhammad Bilal, Muhammad Huzaifa Zahid, Khalid Mahmood, Abdullah Ibrahim, Ali Hasnain Mosvi, Amir Naseer, Sadia Munir
A Preliminary Study On The Small Population Paradigm And Nesting Biology Of Rose-Ringed Parakeets (Psittacula Krameri) In Gujar Khan, Pakistan, Muhammad Bilal, Muhammad Huzaifa Zahid, Khalid Mahmood, Abdullah Ibrahim, Ali Hasnain Mosvi, Amir Naseer, Sadia Munir
Journal of Bioresource Management
Rose-ringed parakeet (P. krameri) is commonly found native psittacid in Pakistan. It is most popular companion bird in Pakistan. It is an unprotected species as per The Punjab Wildlife Act, 1974. The objectives of the present study were to study its population paradigm and basic nesting biology in the Gujar Khan, Punjab, Pakistan. Previously, no studies were carried out to assess its live and vacant nest cavities, nesting site, nest height, cavity position on substrate, and potential roosts in the area. Moreover, this study also assesses the potential threats and factors in this area and conservation of the …
Composition Of Dung Beetle Communities In A Tropical Montane Forest Alters The Rate Of Dung Removal More Than Species Diversity Alone, Elizabeth A. Engle
Composition Of Dung Beetle Communities In A Tropical Montane Forest Alters The Rate Of Dung Removal More Than Species Diversity Alone, Elizabeth A. Engle

Dung beetles provide key ecological functions by degrading and recycling dung. I used experimentally-assembled communities to examine the role of species richness, community biomass, species diversity, species identity, and community composition in dung removal, using Ateuchus chrysopyge, Copris nubilosis, Onothophagus cyanellus, and Dichotomius satanas. I hypothesized: (1) that as species richness, biomass, and diversity increases within a community, dung removal increases; and (2) species are not functionally equivalent, so community composition should influence dung removal rates. As species richness, biomass, and diversity of experimentally-assembled communities increased, the proportion of dung removed also increased. Also, the four species in this study …
Plants And Their Uses; How Communities Of Tolipir, Pakistan Get Benefit, Abu Ul Hassan Faiz, Mehboob Ul Hassan, Fida Muhammad Khan, Lariab Zahra Faiz, Hina Farooq
Plants And Their Uses; How Communities Of Tolipir, Pakistan Get Benefit, Abu Ul Hassan Faiz, Mehboob Ul Hassan, Fida Muhammad Khan, Lariab Zahra Faiz, Hina Farooq
Journal of Bioresource Management
The present study documented ethnobotanical uses of 156 plant species belonged to 93 genera and 51 families listed from five villages of Tolipir landscape (Ali Sojhal, Kanchi Kot, Khori Chana, Kahoo Kot and Noor Kot villages). Study revealed that most of the species were used medicinally, leaves found to be the most frequently used part, for preparation of indigenous recipes and fodder purpose. The current study empirically contributes a huge chunk of ethnobotanical knowledge and depicts its strong connection with indigenous traditions. It is an urgent need to document indigenous uses of plants for future domestication.
Checklist Of Bats In Some Areas Of Azad Jammu And Kashmir, Fakhra Nazir, Inayatullah Malik, Sabiha Shamim
Checklist Of Bats In Some Areas Of Azad Jammu And Kashmir, Fakhra Nazir, Inayatullah Malik, Sabiha Shamim
Journal of Bioresource Management
Bats form an essential part of the ecosystem by aiding pollination, keeping insect pests in check and overall maybe helpful as indicators of health status of the ecosystem. This study was conducted to formulate a checklist of bats from different regions in Azad Jammu and Kashmir. Five National parks from Azad Jammu and Kashmir were surveyed for the species of bats present (Dhirkot National Park, Pir Lasura National Park, Pir Chanasi National Park, Banjosa National Park and Tolipir National Park). From the study conducted, 10 species of bats belonging to 5 families were found cumulatively in the five national parks.
Demography And Dendrochronology Of A Disjunct Population Of Eastern Hemlock In Southwestern Ohio, Marie Johnson
Demography And Dendrochronology Of A Disjunct Population Of Eastern Hemlock In Southwestern Ohio, Marie Johnson

Edge and isolated plant populations provide information about the resilience and the most basic resource needs of a species. Plant demography examines changes in population size and structure over time. An isolated, disjunct eastern hemlock population in Clifton Gorge State Nature Preserve, Yellow Springs, Ohio consists of two distinct subpopulations each with different environmental characteristics, reproductive capacities, and health ratings. Both subpopulations at Clifton Gorge were found to exhibit significant decreases in average annual ring width through time. Linear regression modeling determined that average annual growing season precipitation and temperature were the strongest predictors of these growth trends. A comparative …

1. Little is known about the biology or conservation status of Lucanus elaphus Fabricius in North America despite well-documented declines of a related species, Lucanus cervus (L.), in Europe. This study provides information critical to developing conservation plans for L. elaphus including the species’ larval substrate requirements, genetic data and range-wide estimates of habitat suitability. 2. In Mississippi floodplain forests, larval L. elaphus were recovered from a wide range of log sizes and rot types and were either found tunnelling within the wood or feeding beneath logs at the soil–wood interface. The species appears to require 1–2 years to complete …
Likely Successors Of Ash Species In Response To The Emerald Ash Borer In Ohio Forests, Brian Michael Good
Likely Successors Of Ash Species In Response To The Emerald Ash Borer In Ohio Forests, Brian Michael Good

Invasive species have the capability to alter landscapes and change the composition of a forest in a very short time. The recent invasive pest, Agrilus planipennis, emerald ash borer, was unintentionally introduced to the United States via ship route to Michigan. The pest attacks and kills all five native ash species in Ohio. This study focused on an area in west central Ohio not yet affected by the borer. Ash centered plots were used to record all species and sizes (diameter at breast height) within a 5m radius of a central ash tree. Plots ranged in topography and all five …
