Morphology and distribution of lakes under the Laurentide Ice Sheet: implications for ice flow dynamics

open access: yesBoreas, EarlyView.
This study examines the distribution and morphology of lakes under the Laurentide Ice Sheet (LIS) to investigate relationships with ice flow velocity, bedrock and basal thermal regime. Palaeo‐ice streams and lobes were important components of the LIS, and properties of lakes in those regions are quantified at high resolution.

Changes in the Greenland Ice Sheet of the Southeastern Maniitsoq Coast from 1994-2004 and 2009-2019 [PDF]

open access: yes, 2019
Remote sensing mechanisms through the use of technology like the Landsat 5-7 Land Manager satellites are commonly used in conjunction with multispectral methods such as unsupervised classification to record and analyze changes in snow and ice over time ...

Effects of landscape context on avian specialist response to increased surface temperature in protected areas

open access: yesConservation Biology, EarlyView.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Tourist visits to Madagascar's protected areas linked to deforestation decreases within but increases outside protected area boundaries

open access: yesConservation Science and Practice, EarlyView.
Abstract Tourist visits to protected areas (PAs) are a widely promoted, yet largely untested, approach to achieve forest conservation and socioeconomic development. We assessed the impacts of annual tourist visits to 40 Madagascar PAs over 20 years on local deforestation in and around PA boundaries, using a two‐way fixed effects approach to control for

A study of atmospheric diffusion from the LANDSAT imagery [PDF]

open access: yes
LANDSAT multispectral scanner data of the smoke plumes which originated in eastern Cabo Frio, Brazil and crossed over into the Atlantic Ocean, are analyzed to illustrate how high resolution LANDSAT imagery can aid meteorologists in evaluating specific ...

Bee community and trait‐based responses to fire in a Mediterranean landscape

open access: yesInsect Conservation and Diversity, EarlyView.
Fire drives a short‐term increase in bee abundance and diversity, despite its strong negative impact on floral resources. Acting as an environmental filter, fire shapes bee communities as increased post‐fire fine‐scale heterogeneity favors bees with specific functional traits such as ground‐nesting and generalist species.

Comparing soil boundaries delineated by digital analysis of multispectral scanner data from high and low spatial resolution systems [PDF]

open access: yes, 1977
The author has identified the following significant results. Computer-aided analysis techniques used with aircraft MSS data showed that the spatial resolution was sufficient to recognize each soil mapping unit of the test site. Some difficulties occurred

Water availability and land‐use shape the diversity of Odonata in the Middle East

open access: yesInsect Conservation and Diversity, EarlyView.
Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...

Tree growth response and adaptation to climate change and climate extremes: From canopy to stem

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review synthesizes the responses and adaptations of tree growth, including canopy phenology, intra‐annual wood formation dynamics, and annual stem growth, to climate change and climate extremes. It highlights key knowledge gaps for future research to support sustainable forest management and enhance forest carbon storage under ongoing climate ...
