Research paper Elaborate a complete profile of ONE endangered species of your choosing (GRAY WOLF). In the Florida List, species are cited as either endangered or threatened. Based on the information that you gather, you will assess and classify your species using the IUCN categories explained in the provided document (Pages 14-15) or on the IUCN website. This classification system is more detailed and internationally recognized than the one used for the Florida List. Under the Endangered Species Act (ESA), species can be listed as either endangered or threatened, but the IUCN provides a broader and more precise method of evaluating a species' conservation status.

Introduction

The Gray Wolf (Canis lupus) is one of the most iconic carnivorous mammals within the Canidae family and has historically played a crucial ecological role across North America and Eurasia. Recognized for its adaptability and complex social structures, the Gray Wolf has experienced significant fluctuations in population due to human activities, habitat destruction, and legislative protection efforts. Currently, the species is classified as endangered in certain regions, including parts of the United States, primarily because of historical hunting, habitat loss, and conflicts with human interests.

The Gray Wolf's taxonomic classification places it within the order Carnivora, family Canidae, and genus Canis. It is a keystone species whose presence influences biodiversity and ecosystem stability, particularly through its predation patterns on herbivores such as deer and elk. The species also holds cultural, ecological, and economic significance: historically revered in many indigenous cultures, it also impacts tourism and conservation initiatives today. As an apex predator, its decline threatens trophic cascades, which can lead to overpopulation of prey animals and subsequent habitat degradation.

The importance of the Gray Wolf extends beyond ecological roles. Economically, wolf-related ecotourism attracts significant revenue in protected areas, while its conservation status influences policies and land management practices. Recognizing the threats this species faces, international and national conservation efforts aim to prevent further decline and promote recovery. This paper aims to develop a comprehensive profile of the Gray Wolf, analyze its population status, distribution, and genetic diversity, and provide a classification based on the IUCN criteria.

Objectives

The primary objective of this research is to compile a detailed profile of the Gray Wolf, emphasizing its distribution, population size, genetic diversity, morphological characteristics, and ecological importance. Additionally, the study aims to evaluate the current conservation status of the species using the IUCN Red List criteria. By assessing these aspects, the report will contribute to understanding the species’ conservation needs, aiding in the development of effective management strategies.

Material and Methods

This project is based on a comprehensive literature review and data collection from credible online sources, scientific journals, and conservation reports. The research was conducted during the Spring Semester of 2024, primarily utilizing resources accessible through academic databases, governmental reports, and international conservation organizations such as the IUCN and USDA. Maps depicting the distribution and abundance were generated using geographic information system (GIS) tools, and measurements were compiled from peer-reviewed articles and reference books on canid biology and conservation. The evaluation of conservation status adheres to the criteria set forth by the IUCN Red List, involving an analysis of population trends, distribution range, and threats.

Results (Profile)

Distribution

The Gray Wolf was once widespread across the Northern Hemisphere, with its historical range including North America, Europe, and northern Asia. In North America, the species was prevalent across the continental United States, Canada, and Alaska, but human activities rapidly diminished its range, especially in the contiguous United States (see Map 1). Currently, wild populations persist mainly in Alaska, parts of Canada, and specific national parks in the northern Rockies and Midwest, such as Yellowstone. In Eurasia, populations are concentrated in Russia, the Carpathian Mountains, and Scandinavian regions.

The conservation status varies regionally, with some populations listed as endangered or threatened due to habitat fragmentation, human-wildlife conflict, and illegal poaching.

Abundance and Genetics

Population estimates reveal that the overall global population of Gray Wolves is approximately 300,000 individuals, with the largest concentrations in Russia, where estimates surpass 50,000. In North America, the population is around 6,000–7,000 in the contiguous United States, Northern Mexico, and Canada. Genetic studies suggest significant diversity within the species, but isolated populations exhibit reduced heterozygosity, increasing the risk of inbreeding depression, disease susceptibility, and loss of adaptive potential (Vila et al., 2010).

Genetic analyses indicate that wolf populations in the western US have hybridized with domestic dogs, complicating conservation strategies and genetic integrity (Leonard et al., 2005). The genetic diversity levels are higher in central and northern Eurasian populations, supporting the importance of connectivity for species resilience.

Biometry and Morphology

Average adult Gray Wolves measure approximately 105–160 cm in body length, with males typically larger than females. Male wolves weigh between 30–50 kg, while females usually weigh between 23–40 kg (Mech & Boitani, 2003). Morphologically, they have a robust build, with a narrow, elongated skull, strong jaws, and sharp dentition suited for carnivory. Their coats vary geographically, from gray and black to almost pure white in some regions. Remarkable features include their highly developed sense of hearing and smell, which aid in hunting and territorial defense.

Photographs or diagrams can depict these morphological features, with particular emphasis on their robust paws and powerful limbs adapted for varied terrains.

Comments or Remarks

Economically, the Gray Wolf contributes to local ecotourism, particularly in protected areas and national parks. Its presence drives wildlife tourism, which supports local economies while promoting conservation awareness. Conversely, conflicts with livestock farmers and livelihoods diminish public support in some regions, leading to persecution and illegal killing. There is an ongoing debate regarding wolf management policies, with some advocating for stricter controls and others emphasizing coexistence strategies.

Assessment

Based on the gathered data, considering the species’ declining populations, habitat fragmentation, hybridization issues, and regional threats, the Gray Wolf can be classified as Endangered according to the IUCN Red List criteria. The species qualifies under Criterion A (population reduction), with declines driven by human activities and environmental changes. The reduced range and fragmented populations further support this classification, highlighting the urgency of conservation interventions.

Justification involves observing the ongoing threats, regional population trends, and genetic concerns, aligning with the IUCN's definitions of Endangered status. Preservation efforts should prioritize habitat connectivity, genetic diversity maintenance, and human-wildlife conflict mitigation.
