Taxonomy and diversity of Marcgraviaceae, north of the São Francisco river, northeast Brazil

open access: yesNordic Journal of Botany, EarlyView.
This study provides a comprehensive assessment of Marcgraviaceae species diversity north of the São Francisco river in northeastern Brazil, analyzing species richness and distribution patterns across 384 000 km² of phytogeographic domains. Through field collections, herbarium studies (both physical and digital), and detailed morphological analyses, we ...

Super-regional land-use change and effects on the grassland specialist flora

open access: yesNature Communications, 2018
Biodiversity declines can be difficult to attribute to habitat loss at large spatial scales. Here, the authors document land-use change in Sweden at high spatial resolution over 70 years, showing that habitat loss at local and landscape scales is ...

Phylogenetics, divergence and morphology of New Zealand Eleotridae (Gobiomorphus Gill) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Ecology at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2006
The genus Gobiomorphus Gill (1863) is the only representative freshwater Eleotridae in New Zealand and is comprised of seven species, of which four are diadromous.

Archaeological and Biogeochemical Investigation of Past Human Relationships With Now‐Endangered Fish Species: Lake Sturgeon and American Eel in Southern Ontario, Canada

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT This paper explores the historical ecology and biogeography of two fish species that are currently endangered in the North American Great Lakes region, that were of great importance to the Indigenous people in the region, and that are the focus of ongoing conservation efforts on the part of descendant communities: lake sturgeon (Acipenser ...

The relative roles of in situ diversification and lineage dispersal underlying diversity patterns at the assemblage level

open access: yesOikos, EarlyView.
Speciation, extinction, and dispersal are the historical processes influencing the spatial distribution of lineages and strongly influence diversity patterns. Here, we apply a recently developed methodological approach to quantify the relative legacies in situ diversification history (i.e.

The future of endemic and threatened birds of the Amazon in the face of global climate change

open access: yesEcology and Evolution
The anthropogenic impacts on the environment, including deforestation and the escalating emissions of greenhouse gases, have significantly contributed to global climate change that can lead to alterations in ecosystems.

Shifts in phenology influence synchrony of flowering plants and their pollinators along an elevation gradient

open access: yesOikos, EarlyView.
Climatic conditions alter the phenology of species, which may threaten the synchrony of biotic interactions. However, how phenological synchrony across entire communities of plants and their pollinators responds to varying environmental conditions remains poorly understood.

Connecting the distribution and diversification of marine plants

open access: yesOikos, EarlyView.
Integration of the evolutionary history with distribution of extant species is necessary to explain present‐day diversity, particularly for ‘foundation' species, such as seagrasses, which create habitats of socioecological relevance. Here, we resolved if varying evolutionary history of seagrass families has imprinted the distribution ranges of extant ...

Fruit use and fruit processing by euphonias, specialized avian frugivores

open access: yesOikos, EarlyView.
Euphonias (Neotropical passerines in the genera Euphonia and Chlorophonia) form the quintessential example of a specialized avian frugivore, combining a high reliance on fruit as food and the restriction of fruit taxa exploited. To understand their specialization, we explored the integration of fruit morphological and nutritional traits with their ...

Of Islands on Islands: Natural Habitat Fragmentation Drives Microallopatric Differentiation in the Context of Distinct Biological Assemblages

open access: yesEnvironmental DNA
An important evolutionary hypothesis posits that much of the biodiversity we see today arose during episodes of natural habitat fragmentation through the interplay of colonization, extinction, adaptation, and speciation.
