Evaluación del hábitat del venado cola blanca (Odocoileus virginianus mexicanus) en cuatro unidades de manejo para la conservación de la vida silvestre de la Mixteca Poblana.
Provedor de dados: 32
Autores: Díaz Hernández, Hernán.
En la Mixteca Poblana el venado cola blanca es una especie que se encuentra sujeta a una fuerte presión de uso debido a su valor económico, estético y cultural. Es por esto que las poblaciones de venado requieren de zonas donde la calidad del hábitat sea favorable y les permita asegurar su subsistencia. En este estudio se evaluaron cuatro modelos de Índice de Aptitud del Hábitat (IAH)  para el venado cola blanca en la región Mixteca Poblana. Dos modelos consideraron tres variables del hábitat, con y sin factor de presión antropogénica. Los otros dos modelos consideraron  solamente las variables estadísticamente significativas en una regresión logística que relacionó las variables con datos de presencia/ausencia del venado obtenidos en 92 transectos. Los...

Tasas de defecación en venado cola blanca (Odocoileus virginianus) a partir del contenido de fibra en heces.
Provedor de dados: 32
Autores: Vega Hernández, Dania Melissa.
El método indirecto de conteo de grupos fecales es muy empleado en la estimación de poblaciones de venado. Para realizar su estimación es necesario utilizar un índice fecal, lo que se conoce como tasa de defecación. Sin embargo, existe gran variación entre las tasas a emplear lo que hace cometer errores al estimar la densidad de población en una determinada área, independientemente de la semejanza en hábitat, lo que puede acarrear estimaciones y decisiones equivocadas en el manejo y aprovechamiento de la especie. Considerando lo anterior, se planteó la construcción de modelos para estimar las tasas de defecación de venado cola blanca a partir de los contenidos de fibra detergente neutro (FDN) y fibra detergente ácido (FDA) en heces. De mayo de 2012 a junio...

Wildlife&amp;#8211;vehicle collisions, especially with deer (Odocoileus spp.), elk (Cervus elaphus), and moose (Alces alces) are numerous and have shown an increasing trend over the last several decades in the United States and Canada. We calculated the costs associated with the average deer&amp;#8211;, elk&amp;#8211;, and moose&amp;#8211;vehicle collision, including vehicle repair costs, human injuries and fatalities, towing, accident attendance and investigation, monetary value to hunters of the animal killed in the collision, and cost of disposal of the animal carcass. In addition, we reviewed the effectiveness and costs of 13 mitigation measures considered effective in reducing collisions with large ungulates. We conducted cost&amp;#8211;benefit...

Molecular identification of Mazama species (Cervidae: Artiodactyla) from natural history collections
Provedor de dados: 74
Autores: Mantellatto,Aline Meira Bonfim; González,Susana; Duarte,José Maurício Barbanti.
Abstract Natural history museum collections constitute an invaluable patrimony of biological diversity for analysing the taxa distribution and evolution. However, it is very common to discover taxonomic misidentification in museum collections based on incorrect data. The aim of this research was to identify brocket deer species (Mazama genus) using molecular markers. We collected 199 samples, performed DNA extraction and species identification using a specific mitochondrial marker based on a fragment of cytochrome b (Cytb) for Neotropical deer. We achieved the amplification and sequencing of 77 specimens and verified that 26% of the skulls were wrongly identified. Moreover, in the museum collections 57% of the specimens were only identified as Mazama sp,...

Morphometry Research of Deer, Sheep, and Human Lumbar Spine: Feasibility of Using Deerand Sheep in Spinal Animal Models
Provedor de dados: 77
Autores: Bai,Xiaofan; Liu,Guomin; Xu,Chuanjie; Zhuang,Yingying; Zhang,Jinlong; Jia,Yuyan; Liu,Yi.
Deer and sheep are used as spinal animal models in clinical and basic research. In this paper, the anatomical morphology, curvature, and morphology index parameters were investigated to assess the feasibility of using deer and sheep as animal models of the human spine. Fresh adult male sheep, deer, and human spine specimens (n = 10 each) were screened and subjected to morphological analyses. The statistical software package SPSS (version 17.0) was used to analyze the statistical similarity and variability among the 3 species. Deer displayed good similarity to human in terms of the vertebral transverse diameter, radius vector, spinal canal transverse diameter, radius vector, and vertebral upper and lower endplate curvature radii. Sheep displayed good...

Anatomical Characteristics of Deer and Sheep Lumbar Spines: Comparison to the Human Lumbar Spine
Provedor de dados: 77
Autores: Wang,Yang; Liu,Ting; Song,Liang-Song; Zhang,Zhi-Xin; Li,You-Qiong; Lu,Lai-Jin.
Deer and sheep spines are often used as models of the human spine. A prerequisite for the use of animal models is information regarding the interspecies differences in the parameters of general interest. This would clarify the limitations of each animal model and substantiate the applicability of the obtained results to humans. Since sufficient data appear to be currently unavailable, we sought to investigate the feasibility of using deer and sheep as animal models for studies on the human spine. The objective of this study was a thorough comparison of the anatomical parameters of deer and sheep spines with those of the human spine. We employed three-dimensional reconstructions of computed tomography images, generated using figure analysis software, which...

Feeding ecology of the endangered huemul (Hippocamelus bisulcus) in Los Alerces National Park, Argentina
Provedor de dados: 81
Autores: Vila,Alejandro R.; Galende,Gladys I.; Pastore,Hernán.
The huemul (Hippocamelus bisulcus) is one of the most endangered and less known neotropical deer. We evaluated its diet in Los Alerces National Park, Argentina. Botanical composition of the diet was studied seasonally using microhistological analysis of fecal samples. Twenty six of the 72 available plant species were recorded in the huemul diet. The annual diet was largely dominated by shrubs (mean + SE= 64.7 + 2.4%) and trees (28.1 + 2.4%). Forbs and grasses only represented 4.6 + 1.1% and 2.5 + 0.6%. The huemul predominantly fed on Nothofagus sp., Maytenus sp., Embothrium coccineum, Schinus patagonicus and Gaultheria mucronata. Diet composition changed significantly between warm-growing and cold-dormant periods. The annual niche breadth was low,...

Developing decision-making tools for improving pasture quality on deer farms in New Zealand
Provedor de dados: 31
Autores: Stevens,   David R.; Woodward,   Simon J.R.; Westbrooke,   Victoria F.C.
This paper describes the development of a learning package to support improved pasture quality on New Zealand deer farms. The first step has been to determine the specific requirements of deer farmers that will enable them to improve pasture quality decisions on-farm. Decision support software that interprets and demonstrates the impacts of pasture quality and animal physiology on the performance of young growing deer has also been developed. Key themes identified to aid pasture management decision-making included identifying the right pasture quality, management systems to maintain pasture quality and maximising the potential of livestock. This paper reports on the type of knowledge that deer farmers require in the learning package.

Provedor de dados: 103
Autores: Oliveira,Márcio L. de; Norris,Darren; Ramírez,José F. M.; Peres,Pedro H. de F.; Galetti,Mauro; Duarte,José M. B.
Scat-detection dogs have been used to locate feces of rare and elusive species across tropical biomes. However their detection efficiency in relation to human observers has rarely been evaluated. In this study, we evaluated the ability of a scat detection dog to locate feces in comparison with human researchers. Human researchers and a scat detection dog surveyed for deer (Mazama spp.) feces in dense ombrofilous Atlantic forest in the Paranapiacaba continuum, SP, Brazil. A controlled experiment was used to assess the maximum effective perpendicular distance from a transect search line that the dog could detect a Mazama spp fecal sample. Results from a linear regression model revealed that the maximum effective perpendicular distance from a transect search...

First molecular and serological detection of Epizootic Hemorrhagic Disease virus in white tailed deer ( Odocoileus virginianus ) from Tamaulipas, Mexico
Provedor de dados: 45
Autores: Merino,J.O.; Cruz,NI. De la; Galvan,G.; León,A.P. De; Burnes,J.
ABSTRACT Epizootic hemorrhagic disease viruses (EHDV) are dsRNA arboviruses transmitted by biting midges of the genus Culicoides that cause disease in domestic and wild ruminants. Epizootic hemorrhagic disease (EHD) is considered the most important infectious disease of white tailed deer (WTD) in North America, some studies in Northeast Mexico reported EHDV-seropositive WTD and EHDV-infected Culicoides vectors. The increasing population of WTD that share habitat with livestock in Northeast México highlights the importance of EHD for the livestock industry in the transboundary region with the U.S. One hundred and twenty two samples from WTD in Tamaulipas state, Mexico were tested by ELISA and RT-PCR for EHDV antibodies and nucleic acid, respectively. Twelve...
