You may find that birds do not fall under this definition and, in fact, leks are also found in fish, insects, and even some mammals. The casual observer cannot detect these leks because they sometimes depend on odorous chemicals, for example in some species of flies. « There`s a concept of having a lek that isn`t mapped to a specific communication channel, » Gibson says. These leks are not well understood because human senses cannot reliably track unknown chemical signals.

It turns out that the definition of a lek is difficult to determine. « It`s not as clean and tidy as you might see in an animal behavior manual, » says Robert Gibson, a biologist at the University of Nebraska-Lincoln who has studied leks in American prairie species. But there are three key ingredients in every lek. One of North America`s leading providers of in situ environmental remediation and geotechnical construction services has faced changes in the.

Parental care has been approached theoretically through the concepts of game theory and evolutionarily stable strategies. Game theory is widely used in the social sciences, especially in economics, but also in sociology. In 1982, John Maynard Smith introduced the idea of the « evolutionarily stable strategy » or ESS in biology. The ESS is the distribution of participants between different strategies, so no new strategy could be better.

Given the changing dynamics of environmental services, companies and investors operating in this market are trying to answer a number of difficult questions to ensure that their strategies are focused on growth: an increase in environmental regulations and the growing importance of environmental, social and governance (ESG) initiatives by companies are converging to increase the importance of responsible use of hazardous substances; environmental pollutants in soil, air and water; and structures damaged by storms and other causes. In addition, the need for increased investment in infrastructure is expected to further stimulate demand for environmental services in the coming decades. Carmack, E., & Macdonald, R. (2008).

Mars Sci. 6:130. doi: 10.3389/fmars.2019.00130 The Greater Sage-Grouse has experienced a significant decline in its population and a shrinking of its historic range, leading to several (unsuccessful) petitions to list the bird for legally protected status under the U.S. Endangered Species Act. Human activities such as energy development, roads, shrub removal, and conversion of habitat to agricultural land have fragmented or destroyed habitats, and current fire loss is a predominant threat, particularly in the western half of the Greater Sage-Grouse range (Brooks et al. 2015), where increased wildfire activity in recent decades has been associated with a dramatic decline in the Greater Sage-Grouse population (Coates et al., As a result, land management agencies have recently developed sagebrush ecosystem management objectives that focus on preserving Greater Sage-Grouse habitat, including reducing the impact of wildfires (Chambers et al., 2017; see below).

Since the Greater Sage-Grouse is a widespread, often migratory, species that uses different sagebrush habitats at different times of the year, it has been considered a potential « umbrella species », with the preservation of its vast expanse and diversity of habitats likely benefiting many other sagebrush-associated species (Rowland et al., 2006). At first glance, it may seem that females do not derive any direct benefit from lekking, as males contribute genes to offspring only when there is no parental care or other benefits. [45] However, Lekking reduces the cost of searching for females, as the gathering of males facilitates mate selection. [46] Women do not have to travel as far as they are able to evaluate and compare several men in the same environment. In addition, the presence of males in the same location can reduce the amount of time a female is susceptible to predators. When female marbled frogs are under predatory pressure, they routinely choose leks near their release sites; It has been observed that high call rates among men shorten women`s search time. [47] The sac-winged bat, Saccopteryx bilineata, is characterized by a female tusk mating system in which males defend females in a harem area. Courtship and harem defense in this species include energetically expensive flight maneuvers and hovering demonstrations. A double-labeled water experiment showed that the mass-specific metabolism rate of harem males increased with harem size. Males usually mark the boundaries of their territories and defend these areas against intrusion by other males. Adult males try to attract females to their harem areas with acoustic, visual and olfactory representations.

In daytime quarters, which are often located in well-lit support burrows of large trees around buildings in neotropical regions, females are aggressive both towards each other and towards males. One of the most striking representations of this kind is a hover, in which the smell is spread in the direction of sleeping females. Males perform floating representations throughout the year, although copulations occur only during 2 months of the year. Males sleeping on the edge of harems produce some of the offspring, but males in the harem are on average the most successful. Although harem males are not the exclusive fathers of harem offspring, male reproductive success correlates on average with harem size. Intense competition between males can also be observed in a lek mating system, where males gather and present themselves together to attract females. The only resource that a male defends on a lek is the room where courtship and mating take place. Males arrive early in the breeding season and argue and establish their territories through highly ritualized fighting behavior. Males of lekking mammals have developed elaborate ornaments such as horns, antlers, and vocalizations, which they use in intermale competition to attract females and influence the choice of females. Females move into the arena (lek) where males show up and mate with one or more males depending on the quality of their leks (and resources) or the relative qualities of the males.
