Fish and wildlife resources

Federal land management agencies, most notably the
Bureau of Land Management, National Park Service,
and the U.S. Forest Service, are responsible for
protecting some of the United States’ richest and
most diverse paleontological localities. Federal
paleontological resources, protected under the
Paleontological Resources Preservation Act, span
geologic time and include globally significant fossil
localities preserving America’s Paleontological
Heritage. Federal agencies are ultimately responsible
for these vast and diverse scientific collections, most
of which are curated and made accessible in nonfederal
repositories (NFRs). These NFRs (e.g.,
universities; state, tribal, or local museums) serve as
custodians and stewards for federal paleontology
collections, and their staff are tasked with ensuring
access and long-term preservation. The NFR
managers work cooperatively with federal partners to
curate specimens and share collection data, but the
migration of digital data to federal collection
management systems is especially challenging due
their vast number, differences in how federal
agencies manage their collections, and a lack of
funding for collections work. Legacy collections of
fossil material collected prior to the existence of
computerized databases and a reduced number of
paleontology staff positions in the federal
government present additional limitations. The
Society for the Preservation of Natural History
Collection (SPNHC) Sessional Committee on U.S.
Federal Collections has compiled a series of case
studies, best practices, and recommendations for the
care and management of federal collections. Through
these cooperative efforts, this committee has
identified ways in which the goals of federal and nonfederal
partners could be met more efficiently and
effectively to the benefit of both parties. These are
(1) harmonization of repository agreements across
agencies, (2) establishment of regularly available
federal funding and grants to support care for
specimens collected from federal lands, and (3)
increasing discoverability of federal specimens in
online databases and data aggregators by
standardizing metadata usage related to federal
ownership status. These goals aim to enhance the
management, preservation, and accessibility of
paleontological resources from federal lands as well
as improve the procedures surrounding their initial
collection and use in scientific research, education,
and outreach.

Se estudió la dinámica de las aguas de la parte interna del Golfo de Nicoya ante grandes descargas de los ríos. Valores de 0 ppm fueron encontrados al norte de la Isla Chira representando los valores mas bajos reportados para esta zonay con gran significado para el planeamiento de proyectos de maricultura. Grandes gradientes de salinidad se generan durante la marea baja indicando el grado de estratificación de la aprte interna del Golfo de Nicoya. Altas deswcargas de agua dulce de los ríos está acoplada con valores altos de salinidad en la cuña salada que penetra por el fondo hacia el interior del golfo. Se discute las posibles implicaciones que esta dinámica tiene con la degradación del medio ambiente y el impacto que tendría el manejo de la cuenca hidrográfica del Río Tempisque, especialmente los residuos de la actividad agrícola. BAjo altas descarga del río los valores de salinidad están corelaciones con valores de profundidad, donde la fricción entre capas y bombeo por marea pad...

The aim of the present study was to evaluate the potential use of otolith microchemistry (Sr:Ca and Ba:Ca ratios) to identify silver mullet, Mugil curema, populations in Southeastern Caribbean Sea. Fish samples were collected in 7 areas of Nueva Esparta State (Venezuela). The otolith Sr:Ca and Ba:Ca ratios and water Sr:Ca were determined (by ICP-OES and EDTA volumetric method). Otoliths Sr:Ca and Ba:Ca ratios and Sr:Ca partition coefficient of mullets in Cubagua island (south of the State) were significantly different from ratios in La Guardia (north of the State). A discriminant analysis of otolith Sr:Ca and Ba:Ca ratios separated Cubagua Island from La Guardia values. These results suggest the existence of different mullet groups in the Southeastern Caribbean Sea. For this, the simultaneous use of Sr:Ca and Ba:Ca ratios could be a potential tool to identify populations in the study area.

The project aims to reduce poverty in Zambia by introducing commercially valuable fish species, bluefin tuna and salmon fingerlings bred in captivity from Alaska, Japan, and Australia, into select Zambian lakes. This sustainable aquaculture practice will increase fish production, reduce pressure on overexploited wild fish stocks, enhance nutrition by introducing omega-3-rich fish into Zambian diets, improve public health, and empower communities by creating jobs and income streams. The project aligns with conservation principles by minimizing environmental impact and promoting responsible practices through sustainable aquaculture techniques and community-based management. By fostering a thriving aquaculture sector and alleviating pressure on wild fish stocks, this project offers a sustainable solution to poverty reduction and nutritional enhancement in Zambia.

A comparative analysis of the parasite fauna of the southern blue whiting Micromesistius australis was carried out on 165 specimens caught around the southern cone of South America in 4 fishing zones, three from the Pacific Ocean (South to Golfo de Penas, Diego Ramírez Islands and Navarino Island) and one from the Atlantic Ocean (Malvinas Islands). The goal was to detect possible population units or migratory patterns of the southern blue whiting. Fish samples from the Pacific Ocean were collected between October and December 2006 while those from Malvinas Islands were taken in December 2007. A total of 7,621 parasite individuals were collected and determined as members of 19 nominal taxa. The parasite fauna composition was similar between fishing areas but statistical analyses revealed significant differences in absolute and relative abundances of several taxa in infracommunities. After adjusting by the effect of host body size, it was found that the fishing zone had a significant effect on variations in total abundance, taxonomic richness, diversity and composition of parasite infracommunities. Some of these variations might correspond to the different local ecological scenarios in which the southern whiting inhabit around the southern cone of South America, and indicate that southern blue whiting stay and move differentially among fishing zones. These observations allow us to conclude that southern blue whiting do not constitute an ecologically homogeneous unit across the study area.

The growth and sprawl of the American black bear (Ursus americanus) population have been observed and monitored in the past two decades, especially in south-central Kentucky. To better manage human-black bear interaction and develop informed policy and best practices, the current study sought to 1) understand south-central Kentucky residents' current knowledge of and previous experience with black bears, 2) investigate residents' attitudes toward black bears and regulated hunting in wildlife management; and 3) identify residents' level of acceptance of various black bear related management actions in south-central Kentucky. From February to April 2017, residents of London and Stearns districts (southeastern regions) of the Daniel Boone National Forest, a black bear habitat, were invited to participate in this study. The results from 139 completed surveys showed that residents lacked sufficient knowledge about black bear populations in the region and received minimal information regarding black bear management efforts. In comparison to education efforts and relocation, regulated black bear hunting could be a cost-effective option to promote responsible use of wildlife resources and black bear population control. This study provided lessons and recommendations for black bear management in south-central Kentucky and may be of utilization for any other wildlife conservation areas.

The Leave No Trace Center for Outdoor Ethics (LNT) is a nonprofit educational organization that teaches skills and values for recreating responsibly in the out-of-doors. LNT developed Promoting Environmental Awareness in Kids (PEAK), based on seven ethical principles. The PEAK program provides a pack that contains several interactive activities specifically designed to educate children about the outdoors and the responsible use of shared public lands. While the PEAK program has been in existence for a number of years, the program's effectiveness has not been empirically tested. Moreover, there is limited data regarding responsible environmental attitudes and behavior in elementary school-aged children. The focus of this study was to develop a scale to assess the educational impact of the PEAK program on children. The PEAK Assessment Scale (PAS) was pilot tested in the spring of 200 to assess the psychometric properties. Results of the analysis indicated the scale was reliable (.77) and evidence supports that the scale is unidimensional.

En la zona deltaica estuarina del rio Sinu (ZDERS) se desarrolla una de las pesquerias artesanales mas importantes del norte de Colombia. En esta poco se conoce del impacto que causan los artes de pesca sobre el recurso y mucho menos de aquellas que no son permitidas. Con el proposito de evaluar la selectividad del trasmallo sobre las principales especies comerciales, se estimaron los parametros de seleccion de Mugil incilis, Eugerres plumieri, Prochilodus magdalenae, Ariopsis bonillai y Centropomus undecimalis. Entre 2001 y 2002 se hizo un seguimiento de las unidades economicas de pesca que operan con este arte para colectar datos de frecuencias de tallas discriminados por los cinco tamanos de malla (TM) mas frecuentes (5.08, 6.35, 7.62, 8.89 y 10.16 cm). Con un total de 16427 individuos capturados, se determino que el trasmallo ejerce una presion negativa sobre las especies estudiadas cuando se usan TM entre 5.08 y 7.62 cm. En general, las longitudes optimas de captura estimadas p...
