Tree functional composition, functional diversity, and aboveground biomass show dissimilar trajectories in a tropical secondary forest restored through assisted natural regeneration. [PDF]

Ecol Evol, 2023
We examined regeneration patterns of functional composition, functional diversity, and aboveground biomass in a tropical moist secondary forest after 16–22 years since abandonment. We found dissimilar trajectories and recovery status of functional composition, functional diversity indices, and aboveground biomass.

Past, present, and future geographic range of the relict Mediterranean and Macaronesian Juniperus phoenicea complex. [PDF]

Ecol Evol, 2021
The aim of this study is to model the past, current, and future distribution of J. phoenicea s.s., J. turbinata, and J. canariensis, based on bioclimatic variables using a maximum entropy model (MaxEnt) in the Mediterranean and Macaronesian regions. Climate warming could reduce potential niches of Juniperus phoenicea by 30% and 90% in scenarios RCP2.6 ...

Emotional contagion in nonhuman animals: A review. [PDF]

Wiley Interdiscip Rev Cogn Sci, 2022
Emotional contagion involves matching the perceived emotion of a nearby individual, positive or negative. It is found in all sorts of social species suggesting its importance as a mechanism of coordination. Abstract Emotional contagion, the emotional state‐matching of an individual with another, seems to be crucial for many social species.

Assessing Methane Emissions From Tropical Wetlands: Uncertainties From Natural Variability and Drivers at the Global Scale

Global Biogeochemical Cycles, Volume 37, Issue 9, September 2023., 2023
Abstract Methane (CH4) emissions from tropical wetlands represent half of the global wetland emissions, but uncertainties remain concerning the extent of tropical methane sources. One limitation is to conceive tropical wetlands as a single ecosystem, especially in global land surface models.

Floristic composition and turnover analysis in Dahomey Gap and the surrounding sub‐humid Togolese mountain minor forest refuges: Importance for biogeography and biodiversity conservation in sub‐Saharan Africa

Ecology and Evolution, Volume 12, Issue 10, October 2022., 2022
The origin of the DG is one of the central biogeographical questions in sub‐Saharan Africa, which has been addressed in recent phylogenetic studies. Till date, no study based on large floristic data collected in the DG has addressed this question. Our work, based on large floristic data collected in the DG and compared with those of regional floras, is

Oil Palm Empty Fruit Bunch (OPEFB) Fiber‐Reinforced Acrylic Thermoplastic Composites: Effect of Salt Fog Aging on Tensile, Spectrophotometric, and Thermogravimetric Properties

International Journal of Polymer Science, Volume 2022, Issue 1, 2022., 2022
The prioritization of agroindustry fiber wastes as raw materials in development of composites has become a challenge to obtain higher value‐added products with targeted applications. In this study, natural fiber‐reinforced polymer matrix composites were elaborated using two fiber sizes (605 μm and 633 μm) of oil palm empty fruit bunch (OPEFB) and ...

A synthetic eco‐evolutionary proposal for the conservation of wild relatives of the olive tree

PLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Crop wild relatives (CWR) are valuable sources of genetic diversity for plant breeding. However, the identification of wild untapped genetic resources (i.e., unexploited in crops) is not always straightforward. We propose a methodology to guide the identification and conservation of these resources that integrates both genetic
