Spatial bias in sampling small rodents in the Atlantic Forest: A landscape and accessibility perspective

open access: yesPerspectives in Ecology and Conservation
Understanding the effects of habitat loss and fragmentation on species spatial distribution is challenging, mainly because knowledge of species occurrences is biased.

Portulaca abscondita (Portulacaceae, Caryophyllales), a new microendemic species from Monte Azul, Minas Gerais, Brazil

open access: yesNordic Journal of Botany, EarlyView.
Portulaca (Portulacaceae) is a cosmopolitan genus with centers of diversity in Africa and South America. In Brazil, 22 species are recognized, most occurring in xerophytic environments of the Cerrado, particularly in Campos Rupestres. These rocky montane habitats, especially in northern Minas Gerais state, remain undercollected despite their high ...

Guapira leucophylla (Nyctaginaceae, Caryophyllales), a new species from the northern Espinhaço Range of Minas Gerais, Brazil

open access: yesNordic Journal of Botany, EarlyView.
Guapira Aubl. (Nyctaginaceae, Pisonieae) comprises dioecious shrubs and trees widely distributed in the Neotropics and occupying diverse habitats. In the Brazilian Cerrado, the genus occurs in several phytophysiognomies, including Campos Rupestres, a montane rock ecosystem with high levels of endemism but still marked by significant gaps in botanical ...

Sinningia pampeana sp. nov. (Gesneriaceae) from the Pampa's rocky outcrops in southern Brazil and Uruguay

open access: yesNordic Journal of Botany, EarlyView.
Sinningia pampeana is a new rupicolous species from the rocky outcrops of the Pampa biome in southern Brazil and Uruguay. Morphological analyses based on herbarium material, field observations, and detailed illustrations support its recognition as a distinct species from Sinningia sellovii.

Carbon stock in aboveground biomass and necromass in the Atlantic Forest: an analysis of data published between 2000 and 2021

open access: yesAnais da Academia Brasileira de Ciências
Synthesising knowledge on carbon stocks is an essential tool for understanding the potential of forests to store carbon and its drivers. However, such a synthesis needs to be constructed for the Atlantic Forest due to various methodological approaches ...

Eriope barrinhae (Lamiaceae, Hyptidinae), a new montane species from northern Minas Gerais, Brazil

open access: yesNordic Journal of Botany, EarlyView.
In northern Minas Gerais, in the Monte Azul region, the Pico da Formosa mountain remains poorly explored botanically despite recent discoveries of new taxa. During fieldwork at the summit of this mountain, we discovered a distinctive population of Eriope that differs from all known species by a unique combination of morphological characters.

Swimming Upriver? Exploring the Sources of Freshwater and Marine Fish in Military Diet in Sixteenth‐ to Nineteenth‐Century Northeastern North America

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Atlantic cod were caught in large numbers and shipped from fishing stations in North America to Europe and the Caribbean, and this has been frequently studied zooarchaeologically; however, the exchange of cod and other fish into interior North America has received less study.

Habitat loss reshuffles ecological and evolutionary interactions in a seed dispersal network

open access: yesOikos, EarlyView.
In tropical forests, habitat loss reshapes species composition, favoring generalists and recently emerged lineages while specialists and older evolutionary lineages are lost. However, how changes in species ecological attributes and evolutionary history affect ecological processes is poorly explored.

Continental accumulation of fads2 copy numbers allows sticklebacks to thrive across a diversity of nutritional landscapes

open access: yesOikos, EarlyView.
Nutrients, including vital organic compounds, vary in availability across ecosystems, with the potential to act as a source of selection for traits that increase nutrient acquisition and biosynthesis. Compared to freshwaters, marine ecosystems are richer in the omega‐3 long‐chain polyunsaturated fatty acid (n‐3 LC‐PUFA) docosahexaenoic acid (DHA ...
