Different model assumptions about plant hydraulics and photosynthetic temperature acclimation yield diverging implications for tropical forest resilience

Claire Marie Zarakas, Abigail L. S. Swann, Charles D. Koven, et al.

Published: 2024-04-04
Subjects: Ecology and Evolutionary Biology

Tropical forest photosynthesis can decline at high temperatures due to (1) biochemical responses to increasing temperature and (2) stomatal responses to increasing vapor pressure deficit (VPD), which is associated with increasing temperature. It is challenging to disentangle the influence of these two mechanisms on photosynthesis in observations, because temperature and VPD are tightly correlated [...]

Different growth response of mountain rangeland habitats to annual weather fluctuations

Fabio Oriani, Helge Aasen, Manuel K. Schneider

Published: 2024-03-13
Subjects: Ecology and Evolutionary Biology

An accurate long-term monitoring of mountain rangelands is of primary importance for biodiversity conservation and sustainability of pastoral land use. In this study, we investigate how the seasonality of growth in nine habitats composing the alpine rangeland ecosystem responds to differences in weather conditions from year to year and how these changes occur along the elevation profile. We apply [...]

Impact attribution is an emerging transdisciplinary sub-discipline of detection and attribution, focused on the social, economic, and ecological impacts of climate change. Here, we provide an overview of common end-to-end frameworks in impact attribution, focusing on examples relating to the human health impacts of climate change. We propose a typology of study designs based on whether [...]

Ten simple rules to bridge ecology and palaeoecology by publishing outside palaeo-ecological journals

Nick Bennett Schafstall, Xavier Benito, Sandra O Brugger, et al.

Published: 2023-11-30
Subjects: Ecology and Evolutionary Biology

Due to a specialised methodology, palaeoecology is often regarded as a separate field from ecology even though it is essential to understand long-term ecological processes that have shaped ecosystems that ecologists study and manage. Even though advances in ecological modelling, sample dating, and proxy-based reconstructions have enabled direct comparison of palaeoecological data with [...]

Underrepresentation of minoritised and historically disadvantaged groups is prevalent in PhD recruitment, particularly in environmental sciences. The environmental science focussed ‘Adapting to the Challenges of a Changing Environment’ Doctoral Training Partnership (ACCE DTP) was awarded funding from the Natural Environment Research Council for an EDI-centred project. This project aimed to [...]

Wildfire smoke impacts lake ecosystems

Mary Jade Farruggia, Janice Brahney, Steven Sadro, et al.

Published: 2023-11-06
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology

Wildfire activity is increasing globally. The resulting smoke plumes can travel hundreds to thousands of kilometers, reflecting or scattering sunlight and depositing ash within ecosystems. Several key physical, chemical, and biological processes in lakes are controlled by factors affected by smoke. The spatial and temporal scales of lake exposure to smoke are extensive and underrecognized. We [...]

Spatial standardization of taxon occurrence data—a call to action

Gawain T. Antell, Roger B.J. Benson, Erin E Saupe

Published: 2023-10-20
Subjects: Biodiversity, Ecology and Evolutionary Biology, Paleobiology, Paleontology, Statistical Methodology

The fossil record is spatiotemporally heterogeneous: taxon occurrence data have patchy spatial distributions, and this patchiness varies through time. Large-scale quantitative paleobiology studies that fail to account for heterogeneous sampling coverage will generate uninformative inferences at best and confidently draw wrong conclusions at worst. Explicitly spatial methods of standardization are [...]

“NASA’s citizen science projects are collaborations between scientists and interested members of the public. Through these collaborations, volunteers (known as citizen scientists) have helped make thou- sands of important scientific discoveries.” (NASA) In January 2021, using the GLOBE Observer app, the Mt.

In this Survey, the Tabor Tree Project identified 130 trees randomly in all 12 zones of the park called Mt. Tabor in Portland, Oregon. The Majority of the Trees at Mt. Tabor Park are conifers, and specifically Douglas Fir who can live longer than 1,000 years. The oldest one in the park is 496 years old, and sprouted sometime around 1520 AD. Through the efforts of Tree Medicine hikes and Citizen [...]

Clarifying the trophic state concept to advance limnology, management, and interdisciplinary collaboration

Trophic state (TS) characterizes a waterbody’s biological productivity and depends on its morphometry, physics, chemistry, biology, climate, and history. However, multiple TS operational definitions have emerged to meet use-specific classification needs. These differing operational definitions can create inconsistent understanding, can lead to miscommunication, and can result in siloed [...]

1. Global plate models (GPMs) aim to reconstruct the tectonic evolution of the Earth by modelling the motion of the plates and continents through time. These models enable palaeobiologists to study the past distribution of extinct organisms. However, different GPMs exist that vary in their partitioning of the Earth's surface and the modelling of continental motions. Consequently, the preferred [...]

Crowded and warmer: unequal dengue risk at high spatial resolution across a megacity of India

The role of climate factors on transmission of mosquito-borne infections within urban landscapes must be considered in the context of the pronounced spatial heterogeneity of such environments. Socio-demographic and environmental variation challenge control efforts for emergent arboviruses, a major class of pathogens responsible for dengue, Zika and chikungunya, transmitted via the urban mosquito [...]

Sensitive and intensively managed species require carefully thought-out management plans to promote and maintain specific habitat conditions. Urban features and land-use change must be assimilated into these habitat management plans, as they become increasingly present globally. As a case study, several MaxEnt species distribution models were developed that could enable habitat management efforts [...]
