Species :

 

1- The sand lizard (Lacerta agilis) 

From Wikipedia, the free encyclopedia

 

The sand lizard (Lacerta agilis) is a lacertid lizard distributed across most of Europe and eastwards to Mongolia. It does not occur in the Iberian peninsula or European Turkey. Its distribution is often patchy.[2]

Conservation status :

 

 


Least Concern (IUCN 3.1) [1]

Scientific classification :

Kingdom:Animalia

Phylum:Chordata

Class:Reptilia

Order:Squamata

Family:Lacertidae

Genus:Lacerta

Species:L. agilis

Binomial name :

Lacerta agilis
Linnaeus, 1758

Description :

 

The sand lizard is a sexually dimorphic legged lizard. In northwest Europe, both sexes are characterised by lateral and dorsal strips of ocellated (eye-shaped) markings, dark patches with pale centres. Colouration varies across their European and Russian range. Males have finer markings than females, and their flanks turn bright green during the spring mating season, fading again in the late summer. Sand lizards can reach up to 25 cm (10 in) in length.[3]

 

It has several subspecies, the westernmost of which is L. a. agilis. In this and the other main western subspecies (L. a. argus), the dorsal stripe is thin and interrupted, or not present at all. This applies particularly to the latter subspecies, which also includes a plain red or brown-backed phase without any dorsal markings. In these two subspecies, only the flanks of the males turn green in the mating season, but in the eastern subspecies (predominantly L. a. exigua), males can be wholly green, even outside the breeding season.

Most of these lizards live in Eastern Europe. They are mostly common in Poland, Czech Republic, and countries around that area. They bask on rocks in the day and at night they go into their holes under ground. To protect themselves, they pop off their tails and bite the predators.

Habitat :

 

In the UK, the sand lizard is largely restricted to lowland heathlands and sand dunes in Southern England, and to the coastal sand dunes of Northwest England and Wales. It also occupies a range of man-made habitats within these areas, including railway lines, roadsides, brownfield sites and field boundaries.

 

Conservation status :

 

It is regarded as threatened and is strictly protected under UK law – as it is throughout most of Europe (it is a European Protected Species). This is in contrast to L. a. exigua, whose Russian name translates as the "common lizard". The UK Amphibian and Reptile Conservation Trust coordinates conservation action for the sand lizard, including a successful captive-breeding and reintroduction programme.

 

Reproduction :

 

The female sand lizard lays eggs in loose sand in a sunny location, leaving them to be incubated by the warmth of the ground.

Inbreeding avoidance :

 

When a female sand lizard mates with two or more males, sperm competition within the female's reproductive tract may occur. Active selection of sperm by females appears to occur in a manner that enhances female fitness.[4] On the basis of this selective process, the sperm of males that are more distantly related to the female are preferentially used for fertilization, rather than the sperm of close relatives.[4] This preference may enhance the fitness of progeny by reducing inbreeding depression.

Map of Eurasia

The sand lizard is a small species of lizard that is found across Europe and into parts of Asia. The sand lizard is one of only three species of lizard natively found in the UK along with the slow worm and the common lizard, and is protected in Britain (and much of Europe) as populations are low in most areas.

 

The sand lizard is found inhabiting grass and heath-lands along with coastal dunes throughout it's native range which extends from the United Kingdom, east across Europe to Mongolia. Despite having a fairly wide distribution however, sand lizard populations are sparse and are completely extinct from certain areas of their native habitats.

 

The sand lizard is a relatively small, yet "stocky" lizard species that is usually of a light brown colour, with darker markings running down it's back. Male sand lizards however, are known for their remarkable colour change, as their skin turns from a dull brown to a bright green during the mating season, in order to more easily attract a female to mate with.

 

As with other reptiles, the sand lizard is a cold blooded animal and must therefore, first warm itself up before it is able to hunt for food. Sand lizards spend the daytimes basking on a rock in the hot sun, which warms their blood up, re-charging them for an evening of hunting. The brownish colour of the sand lizard's skin acts as a good camouflage when the sand lizard is sun-bathing.

 

Like many other lizard species, the sand lizard is a carnivorous animal meaning that it has to hunt and eat other animals in order to survive. Sands lizards primarily feast on a variety of invertebrates including insects, grasshoppers and spiders, which they watch closely using their excellent sight before powerfully grabbing hold of their meal with their strong tongue.

 

The small size of the sand lizard, coupled with it's sluggish nature when warming up during the day, makes these animals a prime target for hungry predators. Birds, dogs and cats are the most common predators of the sand lizard, along with habitat destruction or total loss caused by humans.

 

Sand lizards mate in the early summer when males begin to show off their new green patterns in order to attract and impress a female mate. Female sand lizards lay their eggs in the sand where they are incubated by the sun and not by the mother. As with other lizardspecies, very little care is provided by the parents for their young who are independent from a very early age.

 

Today, habitat loss has pushed these lizards into smaller and smaller areas and sand lizardpopulations across Europe are now under threat. The sand lizard is considered to be an animal at threat from extinction in the wild and is protected in much of it's natural range.
