What is a lek mating system?
A lek is an aggregation of male animals gathered to engage in competitive displays and courtship rituals, known as lekking, to entice visiting females which are surveying prospective partners with which to mate.
Are leks monogamous?
Sexual selection in lekking species has been the object of much attention during the last decades. It is possible that in some species, male aggregations function like typical leks: individuals form a monogamous pair bond while displaying in a lek close to the nesting site (Höglund and Alatalo 1995).
Which animal breeds use leks?
mating habits of antelopes are known to form leks: the kob and the lechwe.) As many as 100 males may crowd together in an arena, where the central males may be only 25 metres (80 feet) apart. A few of them monopolize matings with the females, which come specifically to mate and are…
What is a hidden lek?
The “hidden lek” hypothesis suggests that territorial aggregations might be explained by males establishing territories near successful males (“hotshot” model) or by females preferring to mate in large clusters (“female preference” model).
What is lek animal behavior?
lek, in animal behaviour, communal area in which two or more males of a species perform courtship displays. Lek behaviour, also called arena behaviour, is found in a number of insects, birds, and mammals.
What does lek mean in Arabic?

Why is monogamy more common in birds?
Birds are monogamous because their young are tiny, helpless and immature (or altricial) and require loads of parental care. For an indication of just how altricial most nestlings are, look to a typical pied flycatcher nest. The pied flycatcher is a widely studied passerine (and the ‘star’ species of my novel).
What is the term for one faithful lifelong partner?
Monogamy (/məˈnɒɡəmi/ mə-NOG-ə-mee) is a form of dyadic relationship in which an individual has only one partner during their lifetime—alternately, only one partner at any one time (serial monogamy)—as compared to non-monogamy (e.g., polygamy or polyamory).
What is a lek breeder?
A lek breeding system is employed by some polygynous species and is characterised by aggregations of males that females visit primarily for breeding purposes. This results in strong sexual selection pressures on the lek, as males compete for females and females ‘choose’ between males.
What sort of behavior is seen in a lek?
lek, in animal behaviour, communal area in which two or more males of a species perform courtship displays. Lek behaviour, also called arena behaviour, is found in a number of insects, birds, and mammals. Varying degrees of interaction occur between the males, from virtually none to closely cooperative dancing.
Is lekking polygamous?
The Lek Polygyny mating system promotes a heavily skewed mating success rate among lekking males. Although most of the individuals in a lek never receive a mating opportunity, lek polygamy continues to flourish among various species of birds and insects (Sherman, 1999).

What is the success rate of lek mating?
The variation in mating success is quite large in lek mating systems with 70–80% of matings being attributed to only 10–20% of the males present. The main benefit for both sexes is mating success. For males, the costs stem from females’ preferences.
Why do males in a lek mate with females?
As females rarely mate outside of leks, it is advantageous for males to form leks. Although not all males within a lek mate with a female, the unmated males still receive fitness benefits. Kin selection explains that related males congregate to form leks, as a way to attract females and increase inclusive fitness.
Do females benefit from mate choice in lekking European tree frogs?
Although males of the European treefrog do not provide territories, parental care or other resources to females or offspring, females in a lekking species might gain other direct benefits from mate choice ( Kirkpatrick & Ryan 1991 ).
What is the mating pattern of the European treefrog?
The mating pattern of the European treefrog can be described as prolonged breeding (as defined by Wells 1977) with a lek-like mating system, fulfilling the four criteria used by Bradbury (1981) to distinguish a lek mating system from other mating systems.
