Different effects of alpine woody plant expansion on domestic and wild ungulates

Evolution of the landscape-use efficiencies (LUE) of Pyrenean chamois and seasonal livestock along different scenarios of woody plant expansion. Slopes of the linear regression are also reported for each species. Figure: Espunyes et al, 2019.

 

Climatic and land‐use changes are leading to shrub expansion in alpine grasslands. In this work, we address whether wild and domestic herbivores under varying conditions of resource availability will be able to use efficiently their foraging landscape.

In a new study plublished in the journal Global Change Biology authors found that “shrubification” affects herbivores differently depending on their feeding preferences and plasticity. Mixed feeders will manage better in fallow landscapes but free‐ranging livestock will be less efficient, highlighting a growing economic risk for mountain livestock farmers worldwide.

The bioelements, the elementome and the “biogeochemical niche”

Biogeochemical niches_Elementome_2019_1000x
Possible responses of species biogeochemical niches to long-term changes in the abiotic and biotic environmental conditions (possible evolutionary changes in the elementome of species). Authors hypothesize that each species has an optimal function related with its niche traits and thus an optimal content of the distinct bioelements. Figure: Peñuelas, J. et al. Ecology 2019.

 

Every living creature on Earth is made of atoms of the various bioelements (elements used by living organisms) that are harnessed in the construction of molecules, tissues, organisms and communities, as we know them. The most common bioelements are: hydrogen (H) 59%, oxygen (O) 24%, carbon (C) 11%, nitrogen (N) 4%, phosphorus (P) 1% and sulfur (S) 0.1-1% (percentages of total number of atoms in organisms), but there are other bioelements, normally present in low concentrations such as potassium (K), magnesium (Mg), iron (Fe), calcium (Ca), molybdenum (Mo), manganese (Mn) and zinc (Zn). Organisms need these bioelements in specific quantities and proportions to survive and grow.

Distinct species have different functions and life strategies, and have therefore developed distinct structures and adopted a certain combination of metabolic and physiological processes. Each species is thus also expected to have different requirements for each bioelement andbe characterized by an specific bio-elemental composition.

In a new study published in the journal Ecology authors propose that a “biogeochemical niche” can be associated with the classical ecological niche of each species. Authors show from field data examples that a biogeochemical niche is characterized by a particular elementome defined as the content of all (or at least most) bioelements. “The differences in elementome among species are a function of taxonomy and phylogenetic distance, sympatry (the bioelemental compositions should differ more among coexisting than among non-coexisting species to avoid competitive pressure), and homeostasis with a continuum between high homeostasis/low plasticity and low homeostasis/high plasticity”, explains Prof. Josep Penuelas from CREAF-CSIC Barcelona.

The biogeochemical niche hypothesis proposed in this paper has the advantage relative to other associated theoretical niche hypotheses that it can be easily characterized by actual quantification of a measurable trait: the elementome of a given organism or a community, being potentially applicable across taxa and habitats. The changes in bioelemental availability can determine genotypic selection and therefore have a feedback on ecosystem function and organization.

“Further studies are warranted to discern the ecological and evolutionary processes involved in the biogeochemical niche of all types of individuals, taxa and ecosystems. The changes of bioelements availability and use at long timescales should determine phenotypic selection and therefore also ecosystem function and organization, and, at the end, the evolution of life and the environment”, says Prof. Jordi Sardans from CREAF-CSIC.

Kick off meeting of the FutureArtic project

Great kick off meeting of the FutureArtic project in Sitges. Interesting presentations that guarantee a promising development of this project.

The main aims of the Sitges workshop were to:

  • Create a platform to get an in depth overview on the past and ongoing research activities within ForHot (the previous experiment at the site).
  • Have an official kick-off meeting for the FutureArctic ITN project.

Climate change will affect arctic and subarctic ecosystems more than other ecosystems worldwide, with temperature increases expected up to 4-6°C. Overarching and basic questions remain unanswered, partially due to limited access of these remote areas and technological limitations: How much carbon will escape from the Arctic under a future climate? How do the multitude of ecosystem processes, driven by plant growth, microbial activities and soil characteristics, interact to determine soil carbon storage capacity?. The H2020 ITN ‘FutureArctic’ aims to pave the way for generalized permanently connected data acquisition systems for key environmental variables and processes.

7th ForHot annual meeting

Excellent working sessions at the 7th ForHot annual meeting in Sitges. Interesting and valuable presentations that will enable to advance in the study of how various ecosystem processes are affected by temperature.

The ForHot project is based on the study of a natural soil warming generated by the earth-quake that shocked S-Iceland in May 2008.

On May 29, 2008, there was an earthquake in S-Iceland that measured 6.3 on the Richter scale. One of its many implications was that geothermal systems close to its epicentre were disturbed. At Reykir, one of the campuses of the Agricultural University of Iceland, one such geothermal system moved from its previous location, to a new and previously “cold” area. The new belowground geothermal channels (in the bedrock) resulted in soil temperature to increase in the new area that is ca. 4 ha in size.

Variance in biomass-allocation fractions is explained by distribution in European trees

xxxxxxxxxxxxxxxxxxxxxxxx Tree_Pixabay_Feb2019 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Plant morphology traits, as the size of individual plants, has high functional importance. In a new study in the journal New Phytologist authors analyse the ability of 80 species of European trees species to modify its architecture in response to changes in the environment. Figure: Pixabay

 

Plant morphology has been described as an equilibrium between constraints to plant growth and exogenous environmental stressors. Intraspecific variability in ecological traits confers the ability of a species to adapt to an ever-changing environment.

Fractions of biomass allocation in plants (BAFs) defined as the ratio of plant biomass of organs (the stem, branches, leaves and roots) to total plant biomass, and represent both ecological traits and direct expressions of investment strategies and so have important implications on plant fitness, particularly under current global change.

In a new study in the journal New Phytologist authors combined data on BAFs of trees in > 10 000 forest plots with their distributions in Europe. The study aimed to test whether plant species with wider distributions have more or less variable intraspecific variance of the BAFs foliage–woody biomass and shoot–root ratios than species with limited distribution.

Authors show that a combination of 36% tree genetic diversity and 64% environmental variability explains variance in BAFs and implies that changes in genetic diversity occur quickly. “Genetic diversity should thus play a key role in regulating species responses to future climate change. Loss of habitat, even if transient, could induce a loss of genetic diversity and hinder species survival”, explains Dr. Stavros D. Veresoglou from the Institut fur Biologie, Plant Ecology, Freie Universitat Berlin, Germany and the Faculty of Agriculture, Aristotle University of Thessaloniki, Greece.

In summary, the study indicates that BAFs were more variable in trees with extensive distributions. Most notably, authors made the point that it was a higher genetic variability that resulted in more variable BAFs for tree species with extensive distributions. “We thus present evidence that the loss of habitat for tree species through rapid loss of genetic diversity could lower the ability of the species to modify its architecture (BAFs) in response to changes in the environment. It is thus likely that any loss of habitat may not be as reversible as many believe”, says Prof. Josep Peñuelas from CREAF-CSIC.

Life and the five biological laws. Lessons for global change models and sustainability

forest_sunset_Pixabay_Feb2019
In a new study in the journal Ecological complexity authors establish the five laws that rule life, arguing that biology adapts to what is available, recycles material and extracts energy from the environment while evolving to develop structures and functions optimized for their environment. Figure: Pixabay

 

Life on Earth is the result of evolutionary processes acting on a continuous accumulation of structural and functional information by combination and innovation in the use of matter and endo- (inside the organism) and exosomatic (outside the organism) energy and on discontinuous processes of death and destruction that recycle the materials that form structure, information and energy compounds, such as proteins, DNA and ATP, respectively.

In a new study in the journal Ecological complexity authors define five life laws for these vital processes. These processes cannot exceed natural limits of size and rates because they are constrained by space, matter and energy; biology builds on what is possible within these physicochemical limits

“Learning from the way nature deals with the accumulation of information, the limits of size and the rates at which life can acquire and expend energy and resources for maintenance, growth and competition will help us to model and manage our environmental future and sustainability”, explains Prof. Dennis Baldocchi from University of California, Berkeley.

According to this study, the five most prominent laws pertinent to life and ecology are:

  1. The law of mass conservation (introduced by Lomonosov and Lavoisier)
  2. The first law of thermodynamics: energy cannot be created or destroyed in an isolated system
  3. The second law of thermodynamics, the entropy of any isolated system always increases
  4. Information content is a power of the size of the material store with an exponent larger than one
  5. Basic mechanisms such as natural selection, self-organization and random processes drive evolution, generating the huge complexity of organisms and ecosystems.

“Life has adapted to these ecological laws and physical limits for billions of years, and if we humans want to develop a sustainable world, we would do well to not forget them in our use of space, matter and energy. In the end, we are only another biological species among millions on Earth and are living in a very short period of Earth’s history. We should listen and learn lessons from nature that has had several billion years to evolve and get it as right as possible”, says Prof. Josep Peñuelas from CREAF-CSIC.
