“…Heinrichs et al (2016a) used computergenerated landscapes to explore the effects of patch size, quality, and spatial dispersion on simulated population growth rate and source-sink dynamics. Heinrichs et al (2016b) explored how habitat degradation, loss, and fragmentation can independently affect population performance metrics. Wiens et al (2017) used HexSim to construct a SIBM for a population of golden eagles (Aquila chrysaetos) exposed to risks associated with rapid increases in renewable energy development in southern California, USA.…”

“…All of these traits were favoured by our simulations, which replicate similar circumstances to those frequently occurring in degraded habitats. Our understanding of the mechanisms through which habitat degradation affects species is far from clear since, as we do not understand the types of traits that are selected (Mortelliti et al 2010), even though habitat quality may typically outweigh the importance of habitat loss and fragmentation to species extinctions, as suggested by other agent-based simulations (Heinrichs et al 2016).…”

How a particular threat influences extinction risk may depend on biological traits. Empirical studies relating threats and traits are needed, but data are scarce, making simulations useful. We implemented an eco-evolutionary model to analyse how five threat types influence the extinction risk of virtual organisms differing in body size, maturity age, fecundity, and dispersal ability. Results show that direct killing mostly affected slow-living and low dispersal organisms. Habitat loss and fragmentation both affected larger and less fecund organisms, but drove contrasting responses according to dispersal ability. Habitat degradation and the introduction of invasive competitors had similar effects, mostly affecting large, fast-living, and highly fecund organisms. Many of the reported results confirm previous studies, while others were never tested, creating new hypotheses for future empirical work.

“…Humans have greatly altered the planet’s surface and are the largest cause of habitat loss [ 154 , 155 , 156 , 157 ]. Habitat destruction and transformation leads to immediate and delayed biodiversity loss [ 158 ], and of the 25 endemic hotspots that have the majority of the planet’s biodiversity, none of these hotspots have more than one-third of their pristine habitat remaining [ 154 ].…”

Light is arguably the most important abiotic factor for living organisms. Organisms evolved under specific lighting conditions and their behavior, physiology, and ecology are inexorably linked to light. Understanding light effects on biology could not be more important as present anthropogenic effects are greatly changing the light environments in which animals exist. The two biggest anthropogenic contributors changing light environments are: (1) anthropogenic lighting at night (i.e., light pollution); and (2) deforestation and the built environment. I highlight light importance for butterfly behavior, physiology, and ecology and stress the importance of including light as a conservation factor for conserving butterfly biodiversity. This review focuses on four parts: (1) Introducing the nature and extent of light. (2) Visual and non-visual light reception in butterflies. (3) Implications of unnatural lighting for butterflies across several different behavioral and ecological contexts. (4). Future directions for quantifying the threat of unnatural lighting on butterflies and simple approaches to mitigate unnatural light impacts on butterflies. I urge future research to include light as a factor and end with the hopeful thought that controlling many unnatural light conditions is simply done by flipping a switch.
