Response and resilience of karst subterranean estuary communities to precipitation impacts. [PDF]

Ecol Evol, 2023
Heavy precipitation events caused a halocline shift resulting in a mortality event at a karst subterranean estuary, affecting the fauna inhabiting under the halocline (dotted white line) at the marine groundwater layer (a‐b). Overall, marine species (c‐e) inhabiting the caves were impacted, and cave‐adapted fauna (f‐i) remain resilient to short‐term ...

Effects of interactions between anthropogenic stressors and recurring perturbations on ecosystem resilience and collapse. [PDF]

Conserv Biol, 2023
Abstract Insights into declines in ecosystem resilience and their causes and effects can inform preemptive action to avoid ecosystem collapse and loss of biodiversity, ecosystem services, and human well‐being. Empirical studies of ecosystem collapse are rare and hampered by ecosystem complexity, nonlinear and lagged responses, and interactions across ...

Identifying potentially suitable and accessible refugia to mitigate impacts of an emerging disease on a rare tree. [PDF]

Conserv Biol
Abstract Identifying refugia from emerging threats is vital to ensure the persistence of rare and threatened species, but modeling habitat distribution for these species is challenging and the role of people in refuge management is rarely considered. Myrtle rust is an emerging infectious disease that represents a grave threat to the rare wetland tree ...

Groundwater mapping and locally engaged water governance in a small island terrain: Case study of Karainagar island, Northern Sri Lanka

World Water Policy, Volume 9, Issue 3, Page 456-480, August 2023., 2023
Abstract Groundwater is a vital resource under threat in island communities. Karainagar, a 22 km2 island, is one of seven islands off the coast of Jaffna in Northern Sri Lanka, with its population of just about 11,000 persons, experiences seasonal water shortage, and salinity in groundwater as twin threats impacting on their lives.
