Ecological Factors Influencing Wild Pig Damage To Planted Pine And Hardwood Seedlings, Micah P. Fern, James B. Armstrong, Rebecca J. Barlow, John S. Kush

Human–Wildlife Interactions

Expanding wild pig (Sus scrofa) populations across the southern United States has the potential to impact longleaf pine (Pinus palustris) restoration efforts. The depredation of planted pine seedlings is the most widespread and economically costly damage caused by wild pigs in forest plantations. A better understanding of the ecological factors affecting depredation rates will allow managers to implement best management practices to reduce seedling mortality from wild pigs at their most vulnerable stage of growth. From March 2016 to March 2017, we evaluated wild pig preferences for planted pine and hardwood species at a 34.4-ha cutover …

Examining Patterns Of Animal–Vehicle Collisions In Alabama, Usa, Xiongwen Chen, Shuhong Wu

Human–Wildlife Interactions

Animal–vehicle collisions (AVCs) cause animal death, human injury, and vehicle damage. Uncovering the general patterns and related ecological processes of AVCs is useful for developing mitigation strategies. We examined some previous patterns about AVCs from records in Alabama during 2001 to 2011. The results confirm that: (1) there was a seasonal pattern, with >50% of AVCs occurring in winter; (2) AVCs occurred most frequently at dawn and dusk in the diurnal pattern; and (3) most AVCs occurred on county highways. However, interstate and federal highways had higher numbers of AVCs per km of road. Counties within metropolitan areas had more …

Documentation Of A Gulf Sturgeon Spawning Site On The Yellow River, Alabama, Usa, Brian R. Kreiser, J. Berg, M. Randall, F. Parauka, S. Floyd, B. Young, K. Sulak

Gulf and Caribbean Research

The Gulf Sturgeon Recovery Plan (USFWS, GSMFC and NMFS 1995) stressed the need to provide maximum protection to Gulf sturgeon spawning habitat. The approach employed by various Gulf sturgeon researchers, including ourselves, to document spawning has been to identify potential spawning habitat on the basis of physical characteristics and/or tracking data, collect eggs, and then raise the eggs in the laboratory until the point where the larval fish can be identified (e.g., Marchant and Shutters 1996, Sulak and Clugston 1998, 1999). However, collecting eggs in any appreciable number is usually difficult, and these eggs may not always be viable upon …

Variations In The Ventral Ciliature Of The Crustacean Symbiont Hyalophysa (Ciliophora, Apostomatida) From Mobile Bay And Dauphin Island, Alabama, Stephen C. Landers, Michael A. Zimlich, Tom Coate

Gulf and Caribbean Research

Apostome ciliates are symbiotic organisms whose life cycles are complex and involve specific feeding, divisional, migratory, and phoretic stages. In this study we examined apostome trophonts (the diagnostic stage) from a variety of crustacean hosts in the Mobile Bay and Dauphin Island, Alabama, area. The hosts were grass shrimp (Palaemonetes pugio and P. paludosus), striped hermit crab (Clibanarius vittatus), blue crab (Callinectes sapidus), and pink shrimp (Farfantepenaeus (=Penaeus) duorarum). A number of similar but distinct morphotypes of apostomes were present, those corresponding to descriptions of species of Hyalophysa as well …

The Occurrence Of Lightiella Jones, 1961 (Crustacea: Cephalocarida) In Mobile Bay, Alabama, Richard W. Heard, Gary D. Goeke

Gulf and Caribbean Research

During July 1979, two adult specimens belonging to the cephalocaridan genus Lightiella Jones, 1961 were collected in a box core sample taken at the mouth of Mobile Bay, Alabama. These two specimens were compared to the four described species of Lightiella, and found to be most similar to the northeastern Atlantic species of L. incisa Gooding, 1963 and L. floridana McLaughlin, 1976. Due to a combination of differences in the thoracopodal setation and incisor process of the mandible, the Mobile Bay form cannot at this time be assigned to any of the described species of Lightiella. The two …

Trends In Ex-Vessel Value And Size Composition Of Reported May - August Catches Of Brown Shrimp And White Shrimp From The Texas, Louisiana, Mississippi, And Alabama Coasts, 1960-1978, Charles Wax Caillouet, Dennis Brian Koi

Gulf and Caribbean Research

Exponential models were used to characterize (1) ex-vessel value (in dollars) per shrimp by size category (count; i.e., number of shrimp per pound, heads off); (2) size composition (expressed as cumulative weight of the catch in pounds, heads off, by size category); and (3) ex-vessel value composition (expressed as cumulative ex-vessel value, in dollars, of the catch by size category) for reported May-August catches (inshore and offshore combined) of brown shrimp (Penaeus aztecus) and white shrimp (P. setiferus) from the Texas, Louisiana, Mississippi, and Alabama coasts (statistical areas 10-21) from 1960 to 1978. Exponents of the …

Penaeid Shrimp Distributions In Mobile Bay, Alabama, Including Low-Salinity Records, Harold C. Loesch

Gulf and Caribbean Research

Low-salinity records in the Gulf of Mexico area for taking Penaeus duorarum in water of 0.7‰ and 28°C, and Penaeus aztecus in water of 0.2‰ and 29.5°C were established in Mobile Bay, Alabama. Catches in Mobile Bay of approximately 20,000 each of P. aztecus and Penaeus setiferus, distributed over a 30-month period, show that P. aztecus taken in the hotter months had a wider salinity preference (5 to 30‰) than those taken in the cooler months (10 to 15‰). During the warmer months P. setiferus was most common in waters below 5‰ and during the winter months was almost …
