Peccaries rely on their social structure to defend territory, protect against predators, regulate temperature, and interact with other members of the species. [ 14 ] Peccaries have scent glands below each eye and another on their backs, though these are believed to be rudimentary in P. maximus .
For example, plants of the genus Eucalyptus contain flammable oils that encourage fire and hard sclerophyll leaves to resist heat and drought, ensuring their dominance over less fire-tolerant species. [1] [2] Dense bark, shedding lower branches, and high water content in external structures may also protect trees from rising temperatures. [3]
[96] [93] For climbing down a tree headfirst—an unusual ability for a mammal of its size—a raccoon rotates its hind feet so they are pointing backwards. [97] [93] Raccoons have a dual cooling system to regulate their temperature; that is, they are able to both sweat and pant for heat dissipation. [98] [99]
From June 25 to July 2, 2021, the Pacific Northwest experienced a record-breaking heat wave that sent the normally temperate region into Death Valley-like extremes that took a heavy toll on trees ...

Wildlife biologist Gilberto Pozo counted about 83 of the animals dead or dying on the ground under trees. The die-off started around May 5 and hit its peak over the weekend. “They were falling ...
An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat"), more commonly referred to as a "cold-blooded animal", [1] is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature. [2]
The guanaco is a diurnal animal. It lives in small herds consisting of one male and several females with their young. When the male detects danger, he warns the group by bleating. The guanaco can run up to 64 km/h (40 mph; 18 m/s).
