Coefficients in Taylor's law increase with the time scale of water clarity measurements in a global suite of lakes.

Identifying the scaling rules describing ecological patterns across time and space is a central challenge in ecology. Taylor's law of fluctuation scaling, which states that the variance of a population's size or density is proportional to a positive power of the mean size or density, has been widely observed in population dynamics and characterizes variability in multiple scientific domains. However, it is unclear if this phenomenon accurately describes ecological patterns across many orders of magnitude in time, and therefore links otherwise disparate observations.

Earlier pubertal timing, not tempo, links time-limited early adversity with psychopathology.

Evolutionary-developmental theories propose that early adverse experiences adaptively shift the timing (i.e., onset) and tempo (i.

UV LED wastewater disinfection: The future is upon us.

The world's first full-scale, 280 nm UV LED reactor for wastewater disinfection was tested at flows of 545 and 817 m day. The system achieved > 3 average log reduction of total coliform at 545 m day and the 817 m day flow rate achieved over > 2.5 average log reduction for all operational conditions.

A critical review of ultra-violet light emitting diodes as a one water disinfection technology.

UV light emitting diode (LED) disinfection technologies have advanced over the last decade and expanded the design space for applications in point of use, industrial, and now full-scale water treatment. This literature review examines the progression of UV LED technologies from 2007 to 2023 using key features such as total optical power, price, and wall-plug efficiency. The review found that optical power is increasing while the price per Watt is decreasing; however, the wall plug energy (WPE) is slowly improving over the last decade.

Two tiers, not one: Different sources of extrinsic mortality have opposing effects on life history traits.

Guided by concepts from life history (LH) theory, a large human research literature has tested the hypothesis that exposures to extrinsic mortality (EM) promote the development of faster LH strategies (e.g., earlier/faster reproduction, higher offspring number).
