Policy Options For Forest-Disturbance-Adapted Species Management: Assessing The Rusty Blackbird In New York’S Adirondack Park, Louis W. Hallstrom, Stephen Bird Jan 2022

Policy Options For Forest-Disturbance-Adapted Species Management: Assessing The Rusty Blackbird In New York’S Adirondack Park, Louis W. Hallstrom, Stephen Bird

Adirondack Journal of Environmental Studies

Wilderness preservation policies can sometimes create protections that lack enough flexibility to address a variety of species needs. Rusty Blackbird populations in the United States have been declining for decades due to a multitude of stressors. Populations have declined by greater than 95% since 1966 according to the breeding bird surveys (Greenburg et al., 2011). The Wilderness and Wild Forest land use designations in the Adirondack Park, New York State, are intended to preserve forests and limit anthropogenic impact on the landscape within the Adirondacks to maintain its “forever wild” status under the New York Constitution. This designation can be …


Gis-Based Spatial Model For Habitat Suitability Of Babirusa (Babyrousa Celebensis), In Gorontalo Province, Muhamad Khairul Rosyidy, Adi Wibowo Feb 2020

Gis-Based Spatial Model For Habitat Suitability Of Babirusa (Babyrousa Celebensis), In Gorontalo Province, Muhamad Khairul Rosyidy, Adi Wibowo

Jurnal Geografi Lingkungan Tropik (Journal of Geography of Tropical Environments)

Babirusa (Babyrousa celebensis) is an endemic animal from Gorontalo Province whose population is declining day by day due to poaching, land clearing, and selling babirusa meat in traditional markets in Gorontalo Province. Since 1931 this species has begun to be protected in Indonesia, and since 2008, International Union for Conservation of Nature (IUCN) named the babirusa species as a vulnerable category. This study aims to determine the suitability of babirusa habitat areas (Babyrousa celebensis) in Gorontalo Province with a Geographic Information System (GIS) approach and to determine the relationship of physical characteristics for the habitat of the babirusa habitat in …


Collective Effect Of Landfills And Landscape Composition On Bird–Aircraft Collisions, Morgan B. Pfeiffer, Bradley F. Blackwell, Travis L. Devault Jan 2020

Collective Effect Of Landfills And Landscape Composition On Bird–Aircraft Collisions, Morgan B. Pfeiffer, Bradley F. Blackwell, Travis L. Devault

Human–Wildlife Interactions

Ninety-three percent of all reported bird strikes occur below 1,067 m, which based on the typical approach and departure angles of aircraft is within 8–13 km of an airport. Concomitantly, the Federal Aviation Administration and the International Civil Aviation Organization recommend that any feature that would attract hazardous wildlife to the approach and departure airspace be restricted. Thus, preventing the establishment of wildlife attractants, such as municipal solid waste landfills (MSWLFs) within 8 km or 13 km extents (U.S. and international recommendations, respectively) of airports, has been recommended to mitigate the risk of bird–aircraft collisions (strikes). However, robust evidence linking …

Transformation, Wallace M. Meyer Iii

EnviroLab Asia

Prior to leaving for Claremont Colleges’ Envriolab Asia trip to Malaysia and Singapore, I was conflicted by the question: Do we have the moral authority to interfere with resource extraction and oil-palm development in SE Asia? At that time, the trip seemed imperialistic. Why should people from Malaysia, Indonesia or any developing SE Asia country listen to a group of liberal arts college faculty from a city where widespread habitat modifications have led to significant loss of native habitats, declines in biodiversity, and changes in how these ecosystems function? Many observations transformed my opinion and have inspired me to advocate …


Relation Of Riparian Buffer Strips To In-Stream Habitat, Macroinvertebrates And Fish In A Small Iowa Stream, Jeremy P. Duehr, Michael J. Siepker, Clay L. Pierce, Thomas M. Isenhart Jan 2006

Relation Of Riparian Buffer Strips To In-Stream Habitat, Macroinvertebrates And Fish In A Small Iowa Stream, Jeremy P. Duehr, Michael J. Siepker, Clay L. Pierce, Thomas M. Isenhart

Journal of the Iowa Academy of Science: JIAS

Macroinvertebrate and fish habitat is often degraded as a result of agriculture. Riparian buffer strips are commonly used to counteract the negative effects of agriculture in headwater streams. We assessed the relation of multi-aged riparian buffer strips to in-stream habitat, macroinvertebrate and fish assemblages in an Iowa stream. In-stream habitat, macroinvertebrates, and fish were sampled from two buffered sites and two unbuffered sites, with the greatest substrate, water depth, and velocity heterogeneity occurring in buffered sites. The highest macroinvertebrate richness (11) as well as fish species richness (14), diversity (1.99) and IBI score (37) were found in the site buffered …

Distribution And Habitat Of The Southern Two-Lined Salamander, Eurycea Cirrigera, In Will County, Illinois: Implications For Population Management And Monitoring, David Mauger, Timothy Bell, Eric L. Peters Jan 2000

Distribution And Habitat Of The Southern Two-Lined Salamander, Eurycea Cirrigera, In Will County, Illinois: Implications For Population Management And Monitoring, David Mauger, Timothy Bell, Eric L. Peters

Journal of the Iowa Academy of Science: JIAS

The southern two-lined salamander (Eurycea cirrigera) was found to occur at numerous localities within the Kankakee River State Park in Will County, Illinois. The species is restricted to small drainages within the Kankakee River valley that have flow consisting of groundwater that discharges at seeps or springs at or within the valley bluff. Cooler water temperatures and possibly other conditions that are associated with water derived from seep or spring sources may be important factors in determining salamander abundance. This is particularly relevant to larval habitat. These observations suggest that the spring or seep-fed larval habitat may be the primary …


Distribution And Abundance Of Three Freshwater Mussel Species (B1valv1a: U Ntontdae) Correlated With Physical Habitat Characteristics In An Iowa Reservoir, J. R. Straka, J. A. Downing Jan 2000

Distribution And Abundance Of Three Freshwater Mussel Species (B1valv1a: U Ntontdae) Correlated With Physical Habitat Characteristics In An Iowa Reservoir, J. R. Straka, J. A. Downing

Journal of the Iowa Academy of Science: JIAS

A rapid drawdown (weeks) of a reservoir allowed us to determine the combined influence of water depth, maximum effective fetch, bottom slope, and substrate characteristics on abundance of three species of freshwater mussels. The three principal mussel species were significantly (PPyganodon grandis(Say) was most abundant on deeper shelves (ca. 3 m depth, slope 1 km), and sediment organic matter content was moderate (Lampsilis siliquoidea(Barnes), however, was most abundant in shallow water (Potamilus alatus(Say) had a more cosmopolitan depth distribution, but was found only on bottoms with low slope (Pyganodon grandiswas found to be negatively affected by increasing substrate organic matter …


Landscape Associations Of Frog And Toad Species In Iowa And Wisconsin, U.S.A., Melinda G. Knutson, John R. Sauer, Douglas A. Olsen, Michael J. Mossman, Lisa M. Hemesath, Michael J. Lannoo Jan 2000

Landscape Associations Of Frog And Toad Species In Iowa And Wisconsin, U.S.A., Melinda G. Knutson, John R. Sauer, Douglas A. Olsen, Michael J. Mossman, Lisa M. Hemesath, Michael J. Lannoo

Journal of the Iowa Academy of Science: JIAS

Landscape habitat associations of frogs and toads in Iowa and Wisconsin were tested to determine whether they support or refute previous general habitat classifications. We examined which Midwestern species shared similar habitats to see if these associations were consistent across large geographic areas (states). Rana sylvatica (wood frog), Hyla versicolor (eastern gray treefrog), Pseudacris crucifer (spring peeper), and Acris crepitans (cricket frog) were identified as forest species, P. triseriata (chorus frog), H. chrysoscelis (Cope's gray treefrog), R. pipiens (leopard frog), and Bufo americanus (American toad) as grassland species, and R. catesbeiana (bullfrog), R. clamitans (green frog), R. palustris (pickerel frog), …

Iowa's Declining Flora And Fauna: A Review Of Changes Since 1980 And An Outlook For The Future, Neil P. Bernstein Jan 1998

Iowa's Declining Flora And Fauna: A Review Of Changes Since 1980 And An Outlook For The Future, Neil P. Bernstein

Journal of the Iowa Academy of Science: JIAS

The status of Iowa's biodiversity was first summarized at a 1980 Iowa Academy of Science (IAS) symposium that was published in The Proceedings of the Iowa Academy of Science (Vol. 88, No. 1) in 1981. The 1980 symposium was updated in a recent IAS symposium, and the proceedings from this symposium are published, for the most part, in volume 105 of this journal. Most of the authors noted some positive trends, but, overall, species declines and habitat destruction remained a concern.


An Annotated Checklist Of The Spiders Of Northwestern Iowa And The Loess Hills Of Western Iowa, Barbara J. Abraham Jan 1996

An Annotated Checklist Of The Spiders Of Northwestern Iowa And The Loess Hills Of Western Iowa, Barbara J. Abraham

Journal of the Iowa Academy of Science: JIAS

Spiders were collected by the author from various habitats in 16 counties of northwestern Iowa and the loess hills of western Iowa during the summers of 1985 and 1990-1992. Additional donated specimens from the same region in 1981and1989 were identified by the author. Twenty-three families, 92 genera and 184 species have been identified.


The Status Of Three Uncommon Salamanders (Amphibia: Caudata) In Iowa, Jeffery D. Camper Jan 1988

The Status Of Three Uncommon Salamanders (Amphibia: Caudata) In Iowa, Jeffery D. Camper

Journal of the Iowa Academy of Science: JIAS

The smallmouth salamander [Ambystoma texanum (Matthes)], blue-spotted salamander (Ambystoma laterale Hallowell), and central newt [Notophthalmus viridescens louisianensis (Wolterstorff)] were studied in Iowa from fall 1982 through summer 1984. All three species have declined in abundance in Iowa. A. texanum is more abundant and widespread than was previously suspected, but is declining due to habitat destruction. Apparently, only two populations of A. laterale remain in Iowa. N. v. louisianensis has also declined due to habitat destruction, with only three populations known. All three species require ponds in or adjacent to forest. A. ta was found primarily in riparian …
