Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory

Oikos, Volume 2026, Issue 9, September 2026.
Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

First record of the blacktip reef shark Carcharhinus melanopterus (Carcharhiniformes: Carcharhinidae) from the Tropical Eastern Pacific

Revista de Biología Tropical, 2012
The blacktip reef shark Carcharhinus melanopterus, is one of the most common Indo-Pacific reef sharks. On April 29, 2012, a juvenile male blacktip reef shark measuring 89 cm total length (TL), was incidentally caught during a research expedition in ...

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

Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.
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 ...

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

Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.
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.

Global patterns and processes of establishment risk by non‐indigenous marine fish

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
Niche overlap may be critical to consider, even in areas that appear environmentally unsuitable or poorly connected for NIS. Preserving the intrinsic biotic resistance posed by native species can improve the effectiveness of targeted conservation measures.

Dispersal and in Situ Speciation as Contributors to Plant Diversity in the Chocó Region: Insights From Inga Mill. (Leguminosae)

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim To investigate the historical processes underlying the assembly of the flora of the Chocó region, with a focus on the relative contributions of dispersal and in situ speciation. Using Inga (Leguminosae) as a model lineage, we evaluate the origin and diversification of species present in the Chocó.

Methane Emission Reductions Slow Stratospheric Ozone Recovery by Amplifying the Potency of Ozone Depleting Substances

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Reducing methane emissions is important for restricting surface temperature increases. However, methane also influences stratospheric ozone, and its recovery, via chemical and radiative processes. Using the United Kingdom Earth System Model's state‐of‐the‐art methane emission‐driven capability, we examine the impact of methane emission ...

Photoperiod modulates male sexual maturation in the Emperor tetra (Nematobrycon palmeri), a strictly tropical ornamental fish

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Photoperiod manipulation is widely used to regulate reproduction in temperate fish species, but little is known about its effects in strictly tropical species. This study evaluated whether the Emperor tetra (Nematobrycon palmeri), a tropical ornamental fish, can modulate sexual maturation in response to artificial light regimes.
