5. A biologist discovers two populations of wolf spiders whose members appear identical. Members of one
population are found in the leaf litter deep within the woods. Members of the other population are found in
the grass at the edge of the woods. The biologist decides to designate the members of the two populations as
two separate species. Which species concept is this biologist most closely utilizing?
(A) phylogenetic
(B) ecological
(C) Physiological
(D) morphological

(A) 親緣關係物種概念 (phylogenetic): 基於物種的演化歷史和共同祖先。
(B) 生態物種概念 (ecological): 強調物種在生態系統中的角色和生態位的差異。
(C) 生理物種概念 (physiological): 物種在生理上的差異,例如生殖隔離。
(D) 形態物種概念 (morphological): 物種在形態上的差異。
題目指出,這兩個族群分別生活在森林深處的落葉層、森林邊緣的草叢中,暗示牠們可能佔據不同的生態位,並在生態系統中扮演不同的角色。故最可能使用的是生態物種概念,基於棲息地的不同(也就是生態位的不同)來區分物種。
