How does the adaptation of goats vary across different climatic conditions?
Best insight from top research papers
The adaptation of goats to different climatic conditions varies based on genetic selection and environmental pressures. Studies have identified genomic regions associated with adaptability to harsh climates in Asian ecotypes and milk production traits in European breeds . Genetic analyses have shown signatures of natural positive selection in native goat populations in Southwest Asia, influenced by gradual warming and aridity . Research on over 3000 goats worldwide revealed signatures of selection related to environmental adaptation, including genes involved in responses to extreme environments and human purposes . Goat welfare during heat stress exposure is crucial, as heat stress negatively impacts growth, milk, and meat production, affecting welfare under tropical conditions . Understanding these genetic and environmental factors is essential for enhancing goat production and resilience to diverse climatic challenges.

How have different communities adapted to the impacts of climate change?5 answersDifferent communities have shown diverse adaptation strategies to climate change impacts. In rural areas like the Qinghai–Tibetan Plateau, herders with individual management systems (IMS) tend to rent-in grassland, reducing livestock mortality effectively during extreme climatic events, while those with grassland collective management systems (CMS) purchase fodder, facing higher livestock losses. In Nepal, local communities implement over 50 proactive adaptation measures, significantly associated with livelihood options like agricultural diversification and disaster control. Coastal communities in Atlantic Canada exhibit strong social capital, particularly high social trust, but often feel isolated in making climate change adaptation decisions, emphasizing the need for improved public engagement and multilevel governance. These examples highlight the importance of tailored adaptation strategies considering local contexts and resources.
Is there a research article about the relationship of a goat to the weather?5 answersGoat farmers' perceptions of weather variability and climate change influence their coping and adaptation behavior. The study investigates the influence of weather parameters on outdoor run use by dairy goats under temperate weather conditions. The study also examines the physiologic responses of goats to the semiarid environment in northeastern Brazil and suggests strategies to avoid thermal discomfort. Additionally, a study explores the influence of environmental factors like weather and air quality parameters on the occurrence of ectoparasites in goats in different agro-climatic regions of India. Another study tracks the response of hematalogical variables to coccidiosis in goats during a 100-year rain event in Oklahoma, highlighting the risks for animal health associated with growing incidences of excessively wet weather related to climate change.
How crop can adapt with climate change?3 answersCrop adaptation to climate change involves developing crops that can withstand various environmental stresses such as drought, heat, cold, salt, floods, submersion, diseases, and pests, in order to increase yield and ensure food security. Recent advances in genomics-assisted breeding (GAB) and high-throughput sequencing technologies have enabled the identification of stress-responsive genes and quantitative trait loci, leading to the development of climate-resilient crop varieties. Additionally, epigenetic mechanisms, including DNA methylation and histone modifications, play a crucial role in crop adaptation to environmental cues and can be targeted for crop improvement. Understanding and harnessing these epigenetic mechanisms can help in the development of next-generation cultivars with enhanced tolerance/resistance to stresses and balanced agronomic traits. Overall, a combination of genomics-assisted breeding and epigenetic approaches can contribute to the development of climate-resilient crops and ensure global food security in the face of climate change.
How will reptiles adapt to climate change?5 answersReptiles have the ability to adapt to climate change through various mechanisms. They can manipulate the phenotypic attributes of their offspring by altering the timing, location, and structure of nests to enhance offspring viability. Reptiles at high and extra-high elevations are predicted to shift upslope in response to climate change, with extra-high elevation populations gaining more habitat than their high-elevation counterparts. Incubation temperature and food quality both play a role in the growth of reptiles, with higher incubation temperatures potentially leading to reduced growth and maturation, but good alimentation can mitigate these effects. Reptiles also exhibit plasticity in their behavioral and physiological traits in response to short periods of temperature change, which can partially mitigate the impact of rising temperatures. The adaptation responses of reptiles to temperature stress may have implications for their health and the status of wild populations.
What are the climate change adaptations reported in this paper?2 answersClimate change adaptations reported in the papers include: the use of adaptation strategies to minimize negative impacts or exploit potential opportunities; the importance of adaptation in the built environment, particularly in the housing sector, to address risks of overheating, flooding, and water stress; the recognition of adaptation as a key element in dealing with climate change; the tracking and characterization of adaptation action, with a focus on vulnerability assessments and natural systems. Proactive adaptation is commonly reported, especially in developed nations, and extreme events are important stimuli for adaptation across regions. Adaptation actions are more frequently reported in developed nations, with limited reporting on adaptations developed to take advantage of climate change or focusing on specific populations such as women, elderly, or children.
Are we adapting to climate change? Global Environmental Change?5 answersAdapting to climate change is a critical problem facing humanity. The impacts of climate change, such as higher temperatures, extreme events, and changes in ecosystems, are already being felt in various regions. Policy frameworks are being developed to reduce vulnerabilities and support adaptation efforts. However, it is unclear if the existing political economies of adaptation are able to bring about the necessary changes to sustain human needs and values in a dramatically changed climate. Successful adaptation efforts require science-management partnerships, education on climate change science, vulnerability assessment and adaptation tools, integration with multiple management objectives, and flexibility and adaptive learning. While there are potential adaptation solutions for mild climate change, more severe climate change requires systemic changes in resource allocation, such as diversification of production systems and livelihoods. Overall, there is ongoing research and efforts to adapt to climate change, but the effectiveness and implementation of adaptation projects vary.
