Animal migration involves regular movement between locations. It is found in many animal groups and is usually seasonal. Migration ensures access to adequate food supplies and allows animals to reproduce. Prerequisites for migration include sustained movement, energy storage, and designated food sources along migration routes. Animals use both internal cues like hormones and external cues like temperature, daylight hours, and food scarcity to determine when and where to migrate. Migration allows animals to access resources in different habitats and environments.
Many bird species migrate seasonally between breeding and wintering grounds. In autumn, birds travel south from northern breeding grounds to southern wintering grounds, and they make the return trip north in spring. Large birds like geese typically migrate during the day while smaller birds like robins migrate at night. Birds precisely follow the same migratory routes each year, traveling thousands of kilometers, to take advantage of seasonal food availability in different regions.
Bird migration is the regular seasonal movement, often north and south (latitudinal migration), undertaken by many species of birds. Approximately 4,000 of the world's 10,000 bird species migrate. Birds migrate to take advantage of optimal environments and food availability in different seasons, moving from northern breeding grounds in summer to southern non-breeding areas in winter. The Arctic Tern has the longest migration of any bird, flying nearly 50,000 miles per year between Arctic and Antarctic regions. Reasons for migration include following food sources and moving to safer areas for breeding. Types of migration include latitudinal, longitudinal, altitudinal and seasonal variations.
Migratory birds are some of nature's most magnificent creatures that play important ecological, economic, and cultural roles. Neotropical migratory birds nest in North America and migrate south to Latin America and the Caribbean for winter. Over half of bird species nesting in the US are neotropical migrants. These include songbirds, waterfowl, birds of prey, shorebirds, and others. Migratory birds may be at risk due to lack of protection during nesting season or migration. The legislative definition of migratory birds includes species that annually migrate through parts of North America, Central America, South America, Asia, and beyond.
Bird migration is driven primarily by availability of food and involves seasonal movements between breeding and wintering grounds. While some birds migrate long distances, others undertake shorter altitudinal migrations. Migration patterns include leap-frog migration where higher latitude populations winter at lower latitudes bypassing resident populations, as well as chain migration where populations shift ranges gradually. The timing and routes of migration are often genetically programmed but can also be learned behaviors that take advantage of geographic features and weather patterns to aid efficient travel.
Migratory fish species move between freshwater and marine environments or within freshwater systems. There are over 120 species that regularly migrate between saltwater and freshwater globally, including salmon, trout, eels, and sawfish. In Bangladesh, the major migratory fish are hilsa, which travel over 1,200 km inland to spawn, and palla, which are found in the Ganges delta. Conservation efforts are needed to ensure fish migration routes and habitats are protected from impacts of development.
Migratory birds fly long distances each year, sometimes thousands of kilometers, to find better ecological conditions for feeding, breeding, and raising young between summer breeding grounds and southern wintering areas. Different birds have varying migration patterns, with some flying north for summer and south for winter, others breeding far south in Africa and migrating north for winter, or moving horizontally along coasts or to higher altitudes in mountains between seasons. The document includes a route map and list of bird species that migrate, such as cormorants, ducks, and geese.
This document discusses bird migration, including why birds migrate, the benefits of migration, and different types of migration. It notes that migration allows birds to find nesting sites and food, and to escape harsh weather conditions. The main types of migration discussed are latitudinal, altitudinal, and longitudinal migration. Latitudinal migration involves moving from north to south and back based on seasons, altitudinal involves moving up and down slopes or elevations, and longitudinal runs east to west. The document also briefly touches on problems in migration like navigation and stimuli that trigger migration.

This document summarizes navigation and migration in birds. It discusses that birds migrate seasonally between breeding and wintering grounds. Long-distance migrants like the Blackpoll Warbler travel between Canada and Central/South America while short-distance migrants make shorter trips. Migratory journeys are broken into short flights covering 300-600km per night over 3-4 weeks. Birds use various cues and mechanisms for navigation including landmarks, the sun, stars, and the earth's magnetic field. Food availability also influences migratory patterns as insect-eating birds follow insect populations south in winter.

Bird migration is the seasonal journey undertaken by many bird species between breeding and wintering grounds. Over millions of years, environmental changes caused by ice ages shaped birds' migratory habits through natural selection. Physiological and environmental cues trigger migration, prompting birds to accumulate fat stores and prepare for long flights. Migration allows birds to access nesting and food opportunities while escaping harsh weather, lack of resources, and other threats. However, migratory birds now face increasing human threats including habitat destruction and pollution that hinder their long journeys.
This document discusses bird migration. It defines bird migration as regular, extensive movements between breeding and wintering regions for many birds in the northern hemisphere. The main types of migration are latitudinal from north to south, longitudinal from east to west, partial where some individuals migrate and others don't, and seasonal where birds migrate between summer and winter ranges. Causes of migration include seeking food, breeding conditions, and escaping harsh climates. Advantages include access to favorable temperatures, constant food supply, and genetic mixing between populations.
Birds migrate long distances every year between their breeding and wintering grounds due to seasonal changes. Some birds fly thousands of kilometers non-stop to travel between regions with sufficient food sources. Migratory birds face many dangers during their journeys, including harsh weather, lack of food and water, predators, collisions with man-made structures, habitat loss, and pollution. Greece is home to breeding and wintering populations of many migratory bird species, such as swallows, ducks, storks, and falcons, that undertake long-distance migrations each year.
The document discusses bird migration, summarizing some past beliefs about why birds disappeared seasonally and what is now known to be correct. It then discusses the main reasons why birds migrate, including changes in temperature, evolution, glacial cycles, molting, and diet choices. Finally, it outlines some of the patterns, preparations, navigation techniques, hazards, and return process involved in bird migration.
Migratory birds have started arriving in Pakistan from Siberia as the winter season begins. The migration route stretches over 4,500 kilometers from Siberia to northern India. During their journey, the birds make stops at various lakes and water basins in places like Nowshera, Swat, and Chitral in Pakistan. The Wildlife department is working to organize local communities to prevent hunting of the migratory birds as they pass through areas along the Kabul and Indus rivers. Laws protecting migratory birds were enacted after the Ramsar and Bonn conventions of the 1970s.
Birds migrate for various reasons, including to find food and avoid harsh weather conditions. There are different types of avian migration, including latitudinal from north to south, longitudinal from east to west, and altitudinal to high mountains in summer and low valleys in winter. Birds migrate by different modes as well, such as diurnally during the day or nocturnally at night, over varying ranges and altitudes. They follow specific routes and an order, with adults leading and young following. While migration provides benefits like survival and access to better climates, it also poses dangers and energy costs to birds.
This document provides information about common winter bird species seen in Houston backyards and summarizes key facts about bird migration. It discusses the typical migration distances and routes of different bird species in North America. The document explains that birds are triggered to migrate by decreasing daylight hours and hormonal changes, and notes that favorable winds and weather conditions influence when migration occurs. It describes some of the navigational techniques birds use to complete long migrations and identifies threats migrating birds face from human activities like habitat destruction and pollution.
Mechanics and Classification of birds migration along with the needs to migrate. it is helpful to learn the mechanics involved in migration specifically elaborating the roles of environmental factors to force the birds to migrate.
Migratory birds play important ecological, economic, and cultural roles. Over half of bird species nesting in the US are neotropical migratory birds, including songbirds, waterfowl, birds of prey, and shorebirds, that migrate south to Mexico, Central/South America, and the Caribbean for winter. The legislative definition of migratory birds includes species that traverse parts of the US, Canada, Mexico, Russia, or Japan during annual migrations and need protection during nesting and migrations.
Birds migrate for food, as food sources are abundant in warm areas but scarce in cold regions. Some birds, like the Hairy Woodpecker, migrate only short distances, while others, such as the Blue Jay, travel middle distances. The Arctic Tern is considered the champion migrant, traveling as far as 24,000 miles in a single year in its journey between Arctic and Antarctic regions.
Migratory birds face threats from habitat loss, hunting, and collisions with man-made structures. International cooperation is needed to protect birds that migrate across multiple countries. Migratory patterns are genetically programmed and cued by changes in day length, though navigation also involves sensing the earth's magnetic fields and using visual landmarks. Stopover sites between breeding and wintering areas are important but less protected than other areas. Conservation groups have worked to establish protected areas and regulations to help preserve migratory birds and their long-distance journeys.
This document discusses different types of bird migration. It identifies six main types: daily/local, seasonal, cyclic, latitudinal, altitudinal, and longitudinal. Seasonal migration involves birds moving from south to north in summer and north to south in winter, as seen in species like cuckoos and swallows. Latitudinal migration is the most common, with birds traveling from north to south in fall and back in spring, as the American golden plover does from America to Argentina. Altitudinal migration occurs in mountainous areas, with birds moving to lower lands in winter. Long-distance migrants can travel thousands of kilometers, such as the greater shearwater from northern Europe to South Africa. Birds are
Birds migrate for reasons such as finding more food, dispersing their young, avoiding predators, and seeking more favorable climates. They navigate using the sun, stars, and landmarks, and possibly a magnetic sense. Migration is studied using bird ringing where birds are caught, tagged, and released to track their movements. Migrating birds face challenges including harsh weather, lack of resources, and threats from other birds and humans. Activities to teach children about bird migration include making bird houses, reading books, bird watching, marking routes on maps, art projects, and learning about climate and predator risks birds encounter.
This document discusses different types of animal migration and navigation. It defines migration as persistent movements between distinct locations or habitats. There are obligate and facultative types of migration. Navigation abilities allow animals to find their way over long distances using cues like the sun, stars, and magnetic fields. Trail laying with pheromones helps ants navigate efficiently to food sources. Dead reckoning also allows some animals to deduce their position based on direction and distance traveled from a known starting point.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
5. Booted eagle
• Scientific name : Hieraaetus pennatus
• Found in : open areas like desserts or grassland or
even on sea cliffs.
• Migrating : In Europe, most Booted Eagles are
migratory. Only few spent the winter in southern
Europe, for example in southern France or Spain.
Most Booted Eagles leave Europe in the 2nd half of
September and early October. They return between
the end of February and the beginning of April . The
young leave the breeding area before their parents.
6. Siberian crane
• Scientific name : Grus leucogeranus
• Found in :Western siberian
• Migrating place : The eastern populations migrate during winter
to China while the western population winters in Iran and
formerly, in India and Nepal.
7. Grey jungle fowl
• Scientific name : Sonnerat's jungle fowl
• Found in : India
• Migrating :They do not migrate
8. Brown fish owl
• Found in : thick lowland forest and open but
well-wooded country, always near water. They
can also be found in old mango groves or
plantations.
• Migrating :They do not migrate
• Scientific name : Bubo zeylonensis
9. MONARCH BUTTERFLY
•Scientific name :Danaus plexippus
•Found in :Mexico
•Migrating : They migrate across North America.
Eastern/northeastern populations migrate from southern Canada
and the United states to overwintering sites in central Mexico.
Similarly, the western population migrate seasonally from regions
between the Rocky Mountains and the coast of California.
Monarchs also perform small distance migrations in Australia and
New Zealand.
