Melanism in salamanders: effects of insularity, sex and size on dorsal colouration in Salamandra salamandra

Journal of Zoology, Volume 329, Issue 4, Page 340-352, August 2026.
In this study we tested the effects of insularity on amphibian colouration using the fire salamander as a model system. Although increased melanism was not a consistent pattern across all islands, salamanders from one island exhibited higher proportions of black pigmentation than mainland populations, while insular populations overall showed reduced ...

TWO METHODS FOR TREE VOLUME ESTIMATION OF Acacia melanoxylon IN PORTUGAL

FLORESTA, 2011
AbstractTwo models were developed to evaluate total volume under and over-bark of Blackwood (Acacia melanoxylon R. Br.) stand trees. By variance analysis regarding volume with and without bark it was confirmed that trees age is responsible for 48 to 50% of its volumetric behaviour.

Multi-omics analysis reveals changes in lignin metabolism and hormonal regulation in Acacia melanoxylon stems under low boron stress

Plant Stress
Acacia melanoxylon, a valuable and versatile evergreen tree species, plays a critical ecological and economic role; but its molecular and metabolic responses to boron stress have yet to be completely elucidated.

Seasonal Variation of Butterfly Diversity in Subtropical Urban Forests of Nepal

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Butterflies show seasonal fluctuations in diversity and population in response to bioclimatic factors. Studying butterflies in three urban forests in the subtropical region of Nepal, we found that the diversity and community composition differed significantly across seasons, with richness and diversity peaking during the monsoon and abundance peaking ...

Are the ecological and human dimensions of a national park reconcilable? Addressing visitors' preferences for conservation programs

Conservation Science and Practice, Volume 8, Issue 7, July 2026.
The human dimension must be considered in conservation actions. This article presents a discrete choice experiment that analyses the preferences of visitors for the conservation programs being developed in a National Park. The experiment allows identifying certain conflicts between the ecological and social dimensions, and the conclusion is that there ...
