Isoetes ×atruensis (Isoetaceae – Lycopodiopsida), a new interspecific sterile hybrid from Rajasthan of Western India

open access: yesNordic Journal of Botany, EarlyView.
Isoetes ×atruensis hyb. nov. is shown to be a triploid (2n = 3× = 33 + 1) sterile interspecific hybrid between diploid (2n = 2× = 22 + 1) I. coromandelina and tetraploid (2n = 4× = 44 + 1) I. rajasthanensis. It has been found in two locations in Rajasthan, India.

The paradox of mosquito net fishing: Complex socio‐ecological trade‐offs in southwestern Madagascar

open access: yesPeople and Nature, EarlyView.
Abstract Small‐scale fisheries are vital for the livelihoods, nutrition and well‐being of millions of people in coastal regions. In many parts of the Global South, rising poverty, limited alternatives and declining resources have driven the spread of mosquito net fishing (MNF), a non‐selective practice using repurposed health‐distributed nets.

Multiyear measurements of ebullitive methane flux from three subarctic lakes [PDF]

open access: yes, 2013
Ebullition (bubbling) from small lakes and ponds at high latitudes is an important yet unconstrained source of atmospheric methane (CH4). Small water bodies are most abundant in permanently frozen peatlands, and it is speculated that their emissions will

Predicting self‐reported injury status among runners training for the New York City Marathon

open access: yesPM&R, EarlyView.
Abstract Background Although numerous studies have examined risk factors and prevention strategies for running‐related injuries, few have rigorously tested predictive models. Objective To describe injury patterns throughout marathon training and assess the feasibility of machine learning (ML) models in predicting upcoming weekly running injury status ...

Shallow lake economics run deep: Nonlinear aspects of an economic-ecological interest conflict [PDF]

open access: yes
Outcomes of the shallow lake interest conflict are presented in a number of different contexts: quasi-static and dynamic social planning, and quasi-static one-shot and repeated non-cooperative play. As the underlying dynamics are non-convex, the analysis

Phosphorus Release from Bottom Sediments at Lake Wister, Oklahoma, Summer 2010 [PDF]

open access: yes, 2011
A previous reservoir model of Lake Wister, Oklahoma suggested that internal P sources were dominant, and that a watershed management plan need not be developed to address external sources.

Permafrost Distribution in the Canadian Rockies: Key Variables Influencing Patch‐Scale Variability

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The spatial distribution of permafrost in mountainous regions is influenced by various factors such as topography, climate, vegetation, and substrate. Despite the existence of comprehensive permafrost maps at national and global levels, they fail to accurately represent the patch‐scale (e.g., < 25 m) permafrost distribution in characteristic ...
