Constrained body shape among highly genetically divergent allopatric lineages of the supralittoral isopod Ligia occidentalis (Oniscidea). [PDF]

open access: yesEcol Evol, 2016
The rocky supralittoral isopod Ligia occidentalis sensu lato has a broad distribution in the eastern Pacific, where multiple allopatric genetically divergent lineages occur, which are exposed to marked environmental differences. Using geometric morphometrics, we detected statistically significant differences in body shape among highly divergent ...

Assessing the current state of ecological connectivity in a large marine protected area system

open access: yesConservation Biology, Volume 35, Issue 2, Page 699-710, April 2021., 2021
Abstract The establishment of marine protected areas (MPAs) is a critical step in ensuring the continued persistence of marine biodiversity. Although the area protected in MPAs is growing, the movement of individuals (or larvae) among MPAs, termed connectivity, has only recently been included as an objective of many MPAs.

Brains, tools, innovation and biogeography in crows and ravens [PDF]

open access: yes, 2012
BACKGROUND: Crows and ravens (Passeriformes: Corvus) are large-brained birds with enhanced cognitive abilities relative to other birds. They are among the few non-hominid organisms on Earth to be considered intelligent and well-known examples exist of ...

The role of evolutionary time, diversification rates and dispersal in determining the global diversity of a large radiation of passerine birds [PDF]

open access: yes, 2020
Aim: Variation in species diversity among different geographic areas may result from differences in speciation and extinction rates, immigration and time for diversification.

Temperature modulates compensatory responses to food limitation at metamorphosis in a marine invertebrate

open access: yesFunctional Ecology, Volume 34, Issue 8, Page 1564-1576, August 2020., 2020
A free Plain Language Summary can be found within the Supporting Information of this article. Abstract Under climate change, increased temperatures combined with food limitation may be critical for species with complex life cycles, if high growth rates characterize the larval development.

Factors influencing occupancy and density of salt marsh songbirds in northeast Florida

open access: yesJournal of Field Ornithology, Volume 91, Issue 2, Page 156-169, June 2020., 2020
Abstract Salt marshes and the organisms that depend on them are subject to a variety of anthropogenic threats. In Florida, Worthington’s Marsh Wrens (Cistothorus palustris griseus) and MacGillivray’s Seaside Sparrows (Ammospiza maritima macgillivraii) are species of concern that inhabit a small, narrow range of salt marsh in the northeastern corner of ...

Indirect effects of invasive species affecting the population structure of an ecosystem engineer [PDF]

open access: yes, 2015
Species invasion is of increasing concern as non-native species often have negative impacts on ecosystems that they were introduced to. Invaders negatively affect the abundance of native species due to direct interactions like predation and competition ...

The use of taxonomic relationships among species in applied ecological research: Baseline, steps forward and future challenges [PDF]

open access: yes, 2021
Taxonomy is more than a mere exercise of nomenclature and classification of biological diversity: it profiles the identity of species by investigating their biological and ecological traits.

Dynamics of river plumes in the South Brazilian Bight and South Brazil

open access: yesDeutsche Hydrographische Zeitschrift, 2020
The plumes from the rivers of the South Brazilian Bight (SBB) and South Brazil (SB) were studied using a realistic model configuration. River plume variability on continental shelves is driven by the input of river runoff into the shelf, by wind ...
