Climate variability in SE Europe since 1450 AD based on a varved sediment record from Etoliko Lagoon (Western Greece) [PDF]

open access: yes, 2017
To achieve deeper understanding of climate variability during the last millennium in SE Europe, we report new sedimentological and paleoecological data from Etoliko Lagoon, Western Greece.

Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)

open access: yesAdvanced Science, EarlyView.
Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

Effects of processes at the population and community level on carbon dynamics of an ecosystem model [PDF]

open access: yes, 2008
Ecological processes at the population and community level are often ignored in biogeochemical models, however, the effects of excluding these processes at the ecosystem level is uncertain. In this study we analyzed the set of behaviors that emerge after

Warmer paleotemperatures for terrestrial ecosystems [PDF]

open access: yesProceedings of the National Academy of Sciences, 2002
Floras of predominantly wet-soil environments show a greater than expected proportion of toothed leaves, affecting the outcome of leaf physiognomically based temperature estimates. New analyses of foliar physiognomy of plants growing in predominantly wet soils in modern forests suggest that current methods of inferring paleotemperatures from fossil ...

Unveiling Global Diversity of Patescibacteriota and Functional Interactions with Host Microbes

open access: yesAdvanced Science, EarlyView.
Patescibacteriota represents a diverse group of ultra‐small epibiotic bacteria, which is largely overlooked. By integrating ribosomal protein S3‐based community profiling with MAG‐based metabolic potential analyses, this study provides new insights into their distribution, diversity, and potential interactions with other bacteria across diverse ...

Background insect herbivory increases with local elevation but makes minor contribution to element cycling along natural gradients in the Subarctic

open access: yesEcology and Evolution, 2020
Herbivores can exert major controls over biogeochemical cycling. As invertebrates are highly sensitive to temperature shifts (ectothermal), the abundances of insects in high‐latitude systems, where climate warming is rapid, is expected to increase.

Evaluation of ACCESS-S1 seasonal forecasts of growing season precipitation for Western Australia’s wheatbelt region [PDF]

open access: yesJournal of Southern Hemisphere Earth Systems Science, 2023
Seasonal forecasts are increasingly important tools in agricultural crop management. Regions with Mediterranean-type climates typically adopt rain-fed agriculture with minimal irrigation, hence accurate seasonal forecasts of rainfall during the growing ...

Hybridization may aid evolutionary rescue of an endangered East African passerine

open access: yesEvolutionary Applications, 2022
Introgressive hybridization is a process that enables gene flow across species barriers through the backcrossing of hybrids into a parent population.

Exploring the value of Scotland's environment [PDF]

open access: yes, 2003
Protection of the environment can be regarded as representing a substantial cost to business. However, it is typically considered from the point of view of effect on company profitability, rather than its relative importance to human kind.

The 2010 spring drought reduced primary productivity in southwestern China [PDF]

open access: yes, 2012
Many parts of the world experience frequent and severe droughts. Summer drought can significantly reduce primary productivity and carbon sequestration capacity. The impacts of spring droughts, however, have received much less attention.
