Remembering Paul Johnsgard, Linda R, Brown, Josef Kren
Zea E-Books Collection
Paul A. Johnsgard (1931–2021) was a friend of many, an artist, prolific author, teacher, and humble admirer of all living creatures. It was impossible to find someone at Nebraska Audubon Society or Nebraska Ornithologists’ Union meetings who did not know Paul Johnsgard. His more than 100 published books made him known not just in a community of ornithologists, birdwatchers, and bird lovers in the United States but also abroad. He was a world-renowned ornithologist and naturalist who remained deeply embedded in his local culture and its prairie environment.
We invited about 75 people to write a short memory of Paul. …

Key points: 2021 stock assessment outcomes • The West Coast Demersal Scalefish Resource (WCDSR) is halfway into a 20-year recovery plan following a period of overfishing in the 1990s and 2000s. • This latest assessment provides an important “health check” on the recovery status. • The recovery plan is based on maintaining recreational (including charter) and commercial sector’s total fishing mortality below catch limits and protecting key spawning aggregations to recover the WCDSR by 2030. • The Department of Primary Industries and Regional Development (DPIRD) tracks recovery progress by undertaking weight of evidence stock assessments of WCDSR indicator species dhufish …

Fisheries research reports
A recovery program for the West Coast Demersal Scalefish Resource was introduced between late 2007 and early 2010, based on the maintenance of retained catches of demersal species (overall suite and each indicator species) by both the commercial and recreational sectors below 50% of the catches reported in 2005/06 (original catch recovery benchmarks).
Catch reductions were aimed at reducing exploitation levels (F, long-term fishing mortality of the key indicator species’ stocks) to below the threshold reference point (F = M, the natural mortality rate), which would then allow stocks to recover to above the …

Otoliths Of South-Western Australian Fish: A Photographic Catalogue, Chris Dowling, Kim Smith, Elaine Lek, Joshua Brown
Fisheries research reports
Due to the species-specific nature of otoliths and given they are often the only part of the fish preserved when fish die, otolith catalogues can be used in numerous applications, such as diet studies in fish eating animals, including pinnipeds, fish and sea birds; archaeological purposes such as reconstructing indigenous people’s diets from otoliths found in middens or evolutionary history of fish species by comparing fossilized otoliths. Given the unique mixture of subtropical and temperate fish, including many endemic species that occur off the southwest corner of WA having a catalogue for this area is extremely important for people working …

Analysis Of Methods To Measure Heart Rate In Mytilus Edulis, Kristin Pinho
Student Research Poster Presentations 2021
Non-invasive research will be performed to limit the additional stress from equipment and focus on the harmful effects that polluted run-off water has on mussels’ heart rates. The chemical that will be introduced to the laboratory environment will be weed killer. This research will simulate how water pollution affects different aquatic species and how that ultimately leads to environmental changes, while evaluating the most effective methods to conduct this research.

Fisheries research reports
This document provides a cumulative description and assessment of the TDER and all of the fishing activities (i.e. fisheries / fishing sectors) affecting this resource in WA. Future Resource Assessment Reports will assess the Statewide Sharks and Rays Resource. The report is focused on the temperate indicator species (whiskery, gummy, dusky and sandbar sharks) used to assess the suites of demersal sharks and rays that comprise this resource. These species are primarily captured by demersal gillnets used in the TDGDLF that operate in the West Coast and South Coast Bioregions. For the North Coast bioregion, no commercial fishing for sharks …

Industries burn fossil fuels to create goods which releases carbon dioxide into the atmosphere. CO2 contributes to 20% of the world's greenhouse effect, and the level of it in the atmosphere has increased to over 400 ppm when before the French Revolution it fluctuated between 180-280 ppm (NASA, 2016). The coal industry is a big contributor as it contributes to 35% of the total U.S. energy related CO2 emissions (EIA, 2017). This all leads to global warming, which causes rising sea levels, longer plant growing seasons, and an increase in forest fires (NASA).

India is urbanizing very rapidly due to the movement of people from rural areas to urban cities for better opportunities. India does not have the resources or money to back this rapid urbanization of the population in general. This urbanization has created many environmental problems with air and water pollution.

Due to a lack of education among their population, many Brazilians turn to agriculture as a way to provide for themselves and their families. Additionally, low labor costs draw in large commercial companies that establish business in these developing worlds. However, to obtain farmland in the first place, deforestation has become a common practice, where thousands of miles of lush jungles are cleared away for agricultural practices. According to NASA imaging, 224,000 square miles of rainforest have been cleared in the Amazon. If left unchecked, the drastic consequences could harm not only the countries practicing deforestation, but the entire earth.
The North American Quails, Partridges, And Pheasants, Paul A. Johnsgard
The North American Quails, Partridges, And Pheasants, Paul A. Johnsgard
Zea E-Books Collection
This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel’s, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are highly …
