Drought‐driven lipid deficits in overwintering monarch butterflies revealed by δ2H and fatty acid analysis

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract Eastern populations of monarch butterflies (Danaus plexippus) overwinter in the central trans‐volcanic belt of Mexico, relying primarily on lipids accumulated during migration to sustain this several‐month‐long overwintering period. This study shows how drought conditions in north‐central Mexico influenced lipid dynamics in monarchs ...

Electrified rhythms: How hydropower infrastructure transforms hydrosocial relations of riverine communities in the Lower Sogamoso River, Colombia

People and Nature, Volume 8, Issue 3, Page 782-796, March 2026.
Abstract Hydropower dams regulate water flows for millions of downstream inhabitants worldwide, altering water availability. Under a changing climate, flow control is often framed technically and politically as being essential for reducing drought and flood risks. However, it can also disrupt ecological flows, impact livelihoods and erode environmental

Drought reduces the value of both artificial and natural wetlands for gulls breeding in the Mediterranean region

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.
The importance of artificial wetlands for waterbird conservation can be easily overestimated from count data alone. The value of extensive fish ponds as a breeding habitat depends on maintaining the availability of natural marshes as a foraging habitat. This requires reducing impacts from groundwater extraction. Given recent abandonment of aquaculture,

Long‐term comparison shows protected and non‐protected forests differ in harvesting, but not in wildfires or drought‐driven dieback

Journal of Applied Ecology, Volume 63, Issue 2, February 2026.
Lower forest harvesting in Natura 2000 sites may align with socio‐economic barriers often claimed by local communities, but protection does not influence vulnerability to other disturbances. In a general scenario of reduced forest harvesting in the region, we argue that differences in harvesting due to protection are statistically significant but ...

Plant conservation in a changing Mediterranean world

PLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 49-72, January 2026.
The Mediterranean is one of five climatic regions on the planet characterised by a prolonged summer drought, exceptional plant diversity and high rates of endemism. We provide a framework to link the ecology of plant species conservation in the context of rapid and extreme climate deregulation to a philosophical typology of temporal attitudes (i.e ...
