Populations from different parts of the geographic range that a species inhabits may exhibit marked variations in their life histories. 0000031844 00000 n �\YYL.�F���@ۏ@��6"\�,I�..��PP� 1&es$�P:����T�Ę������H�,�rtE���\�1�gRRq�4�������J]B1�T G�#'30�b�c�P&���5%tt>;����s&��! 0000030605 00000 n Section A: Characteristics of Populations 1. ����A�{��1JEZٽ�ّ�}���� ��.|���w����; I�yPh0*�A銁��"��f����Z�����4b��ct r0!�o�~�Q��zBGk�Ă�`��o�d1:������_wЌ��!߁#����^M0�a�$�z4��Q�1������e��z�(�M9�Z�EG܌?�B��BD0�_����b4��2t{]�u��t".%Q�t�&b���t1����2���ԖS�8�=�P�e���Q��6��q�P�/�>�Z�i�:l� �{{S�]YWr`�Z���[��l�1�&˻�!ze�96y��O`R�7��t����A�4�v�(� &��'�:��`��2�ŧ2�����h�ֵ��e̶�S�C�/�&c���Ĕy�:b=,��\q�#PK�P��Yǧ�P�H(�F�H@�iQ�e�ȑ��}��ޕ�\����ҫ�aU��h�u�S�]If�Jh�iI���M����6[[0����BB�v���ߊ��#���^g\�֚mnoa������bϝ��C� ��]'�E���!�����L+:��]���l/R�:�/U�V�C79ھ�2`Xm �rǗ�l^$p^]�� ��S� Natality: Natality refers to the rate of reproduction or birth per unit time. 0000005439 00000 n 0000005486 00000 n One example would be penguins. Population • What is an individual? •Support a claim to identify a species using its population growth curve as evidence. Students use other students in the school as their population and the Lincoln-Peterson method to determine population size. Weed ecology is thus concerned with growth characteristics and adaptations that enable weeds to survive changes in the environment. <> x��TMo�@�#���dwv�[>�4UT� UUE=P�m"����/;�8��i{0fwg޼�f�{�S���FT1Ĩ � There are a number of characteristics of populations that help ecologist and other scientists to monitor and manage wild populations.

Definition: A population of a single species cannot survive by itself because there is inter dependence of one form of life on another. 0000029721 00000 n In population ecology a population is a group of individuals of the same species inhabiting the same area.
