Genetic variation in the endangered Rutaceae species Citrus . . . Citrus hongheensis is a critically endangered species endemic to the Honghe river region in southeastern Yunnan, China Its genetic diversity and differentiation were investigated using Inter-Simple Sequence Repeat (ISSR) markers One hundred primers were screened, and a total of 245 loci were amplified from seven natural populations by 13 informative and reliable primers Of these 245 ISSR
Experimental study of fire spread between multiple full scale . . . This work is novel as in the literature there is negligible data regarding fire spread analyses in informal settlements This has hampered the development of evidence-based responses and fire safety interventions being developed, as it is sometimes unclear how to reduce fire spread The rate of spread during the fire is approximately calculated
The Impact of Climate Change on Agricultural Insect Pests Another study of about 1100 insect species found that climate change due to global warming will drive about 15–37% of these species to extinction by 2050 [59,60] The general consequences of global warming on insect dynamics include: expansion of geographic range, increased survival rates of overwintering populations, increased risk of
Humans Change the World | The Smithsonian Institutions Human . . . The first modern humans shared the planet with at least three species of early humans Over time, as modern humans spread around the world, the other three species became extinct We became the sole survivors in thehuman family tree By 164,000 years ago Modern humans collect and cook shellfish By 130,000 years ago
The ecological and evolutionary consequences of tropicalisation The main difference between HMRE and tropicalisation is that the spread of NIS requires intentional or unintentional artificial transport of species [74] The spread of NIS can occur across all regions of the globe, whereas tropicalisation specifically occurs around adjacent tropical–temperate regions
