Abstract

Species diversify through speciation and accumulate in ecological community, a process known as community assembly. Relying on both evolutionary mechanisms acting at regional scale and ecological mechanisms acting at local scale, the process of community assembly results from intricate interactions among mechanisms at play across varying spatial and temporal scales. During the last decade, community assembly theory has been reconsidered in the light of evolutionary dynamics of species diversification and ecological dynamics have been formalized in an explicit spatial framework (i.e. metacommunity theory). The aims of the present review are: (1) to present the community assembly theory and the main paradigms that have been proposed, (2) to discuss how the metacommunity theory as defined an explicit spatial framework for community ecology, (3)to discuss the potential mechanisms at play during community assembly and their associated predictions, (4) to present new approaches to study community assembly based on phylogenetics approaches and discuss how they have been integrated in empirical studies.

Abstract

Identifying and delineating species are the primary tasks of taxonomy. Owing to the decreasing interest of the nations for taxonomy and the inventory of living beings, funds have been drastically decreasing during the last two decades for taxonomic studies. As a consequence, the worldwide pool of taxonomists has dramatically decreased. DNA barcoding, as an automated tool for species delineation and identification, proved to rejuvenate the field of taxonomy and open new perspectives in ecology and conservation. In the present review, we will discuss how DNA barcoding established as a new paradigm in taxonomy and how DNA barcoding has been recently integrated in taxonomic studies. We will further detail the potential applications for species identifications and discuss how DNA barcoding may positively impact the inventory and conservation of living beings, particularly in biodiversity hotspots. We emphasise the benefit of DNA barcoding for the conservation of Southeast Asian freshwater fishes.

Abstract

Southeast Asia is one of the most geologically complex tropical regions on Earth, in which the intricate interactions among plate tectonics, volcanism and Pleistocene climatic fluctuations led to complex patterns of species distribution. An increasing number of biogeographic studies of the Indonesian ichthyofauna have already partially uncovered the potential mechanisms at the origin of present day species distribution. These studies are currently scattered in the literature and the present review aims at presenting recent progress. Here, we propose a review of this literature with the aim to provide a broad overview of the current progress in the field of Indonesian freshwater fishes biogeography. First, we will briefly present the geology of the Indo-Australian Archipelago (IAA) and highlight the time frame of the geographical settlement of the Indonesian archipelago. Second, we will present the palaeoecological history of Sundaland during the Pleistocene. Finally, we will present the results of recent biogeographic studies across the three biogeographic provinces (Sundaland, Wallacea, Sahul) and discuss how these results fit with geological and palaeoecological scenarios in Indonesia.
