Geological processes shaping freshwater biodiversity: a synthesis of global evidence

Biological Reviews, EarlyView.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Speciation-based ecological indicators for assessing heavy metal mobility and risk in forest lake sediments

Ecological Indicators
Sediments act as long-term sinks for heavy metals in aquatic systems but may also become secondary sources of contamination when environmental conditions change.

Spatial metrics in fire ecology: seeking consistency amidst complexity

Biological Reviews, EarlyView.
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Felsenstein's“one-allele model”of speciation: The role of philopatry in the initial stages of host plant mediated reproductive isolation in Enchenopa binotata

Current Zoology, 2013
The study of speciation genetics is primarily concerned with identifying the genetic traits that allow divergent selection to overcome the homogenizing effects of gene flow.

How phenotypic matching based on neutral mating cues enables speciation in locally adapted populations

Ecology and Evolution, 2019
Maynard Smith's (American Naturalist, 1966, 100, 637) suggestion that in some cases a prerequisite for speciation is the existence of local ecological adaptations has not received much attention to date.

Bacterial Diversification in the Light of the Interactions with Phages: The Genetic Symbionts and Their Role in Ecological Speciation

Frontiers in Ecology and Evolution, 2018
Phages have a major impact on microbial populations. In this work, we discuss how predation, transduction, lysogeny, and phage domestication lead to symbio-centric genomic interactions between bacteria and phages, ranging from antagonistic to mutualistic.

Individualised niches: an integrative conceptual framework across behaviour, ecology, and evolution

Biological Reviews, EarlyView.
ABSTRACT Individuals differ. While seemingly trivial, this insight has nevertheless led to paradigm shifts, as three key fields of organismal biology have seen marked changes in key concepts over the past few decades. In animal behaviour, it has become increasingly recognised that behavioural differences among individuals can be stable over time and ...

Reviewing and benchmarking ecological modelling practices in the context of land use

Ecography, EarlyView.
Despite habitat loss and degradation are the primary drivers of biodiversity loss, different conclusions have been drawn about the importance of land‐use or land‐cover (LULC) change for biodiversity. Differences may be due to the difficulty of framing a coherent model design to assess LULC effects.

Small spatial intervals, big environmental variation: Restinga ecosystems are potential inducers of ecological speciation in the tropical tree Protium icicariba (Burseraceae) [PDF]

Acta Botânica Brasílica
Restingas are ecosystems formed by diverse environments and plant populations separated by small spatial intervals. In this sense, we investigated the morphological, anatomical, and physiological characteristics of two populations of Protium icicariba ...

Environmental and geomorphological drivers of frog diversity on islands worldwide

Ecography, EarlyView.
Island biogeography models primarily rely on island physical features and isolation to explain their biodiversity patterns. While newer models have incorporated functional traits to understand plant distribution, few empirical studies have tried to disentangle geometric constraints from niche‐based processes to predict multiple diversity facets of ...
