Global population size and conservation priority areas for the endangered Titicaca grebe

The Journal of Wildlife Management, Volume 88, Issue 8, November 2024.
The Titicaca grebe is an endangered endemic species found solely in Lake Titicaca, which has not had a population census in 20 years. We offer the first update of this species’ population since 2003, and show its population has increased, rather than suffered the decrease that had been assumed.

Addressing conflict between fishermen and the Titicaca Grebe (Rollandia microptera) through diet analysis

Ibis, Volume 166, Issue 4, Page 1395-1403, October 2024.
Human–wildlife conflict is often a driver of species declines, and understanding the material basis of this conflict is the first step in addressing it. The Titicaca Grebe Rollandia microptera is an endangered endemic species found solely in the Lake Titicaca watershed of Peru and Bolivia, and has experienced population declines due to fisheries ...

Modeling potential consequences of climate‐driven sex reversal on Southern and Summer Flounder population dynamics

Marine and Coastal Fisheries, Volume 16, Issue 2, April 2024.
Abstract Objective We investigate the interacting effects of fishery selectivity and sexual dimorphism by using the fisheries for Southern Flounder Paralichthys lethostigma and Summer Flounder P. dentatus as case studies. In both species, females are larger than males, and temperature‐sensitive sex determination can lead to an increased proportion of ...
