生物多樣性的本底資料及其自然分布式樣,以及影響生物多樣性的內(nèi)在機(jī)制,對生態(tài)系統(tǒng)的研究和保護(hù)至關(guān)重要。然而,相關(guān)資料不足,妨礙了人們對生物多樣性相關(guān)問題產(chǎn)生的原因以及重要性的認(rèn)識,甚至難以避免生態(tài)系統(tǒng)的進(jìn)一步損失。若某一地區(qū)缺乏對動植物區(qū)系詳盡的清查,很難確定該地區(qū)受到威脅的生物資源。東非沿海森林是一個(gè)獨(dú)特的生物地理區(qū)域,有多樣的特有動植物群,因此被確定為世界生物多樣性熱點(diǎn)地區(qū)之一。然而,該地區(qū)植物生物多樣性的分布模式仍然很不清楚。盡管該地區(qū)植物多樣性的研究已有許多,但此前研究都將重點(diǎn)放在物種豐富度和珍稀、特有種的保護(hù)上,而對系統(tǒng)發(fā)育指標(biāo)的保護(hù)關(guān)注較少。本研究旨在1)了解東非沿海森林維管植物的系統(tǒng)發(fā)育多樣性、沿緯度的植物分布式樣、特有植物的保護(hù)等級;2)提供一個(gè)最新的肯尼亞沿海森林地區(qū)植物名錄,并統(tǒng)計(jì)該地區(qū)特有、受威脅和易受威脅的植物物種及其分布。本研究從Rain-bio數(shù)據(jù)庫中共獲得了采自東非沿海森林共32,922個(gè)標(biāo)本記錄,代表了 199科、1284屬、5,056個(gè)物種(其中769特有種),分別占整個(gè)熱帶非洲已發(fā)現(xiàn)的科72.89%、屬40.65%、種22.39%。該地區(qū)各植物生活型從...
