Article Synopsis
- The study investigates voluntary sexual orientation change efforts (SOCE) among 72 men, analyzing whether reported changes reflect a decrease in homosexual orientation or an increase in heterosexual orientation, as well as behavioral shifts.
- Findings show that participants, who were largely religious, mostly experienced a reduction in homosexual attraction, with one-third reporting a significant shift towards heterosexual attraction on the Kinsey scale.
- The data indicates stronger behavioral changes away from homosexual activities rather than an increase in heterosexual behaviors, suggesting SOCE may reinforce religious norms against homosexual behavior without significantly altering underlying attractions.
Lesser prairie-chicken (Tympanuchus pallidicinctus) populations of in the Sand Sagebrush Prairie Ecoregion of southwest Kansas and southeast Colorado, USA, have declined sharply since the mid-1980s. Decreased quality and availability of habitat are believed to be the main drivers of declines. Our objective was to reconstruct broad-scale change in the ecoregion since 1985 as a potential factor in population declines.

However, translocation-induced dispersals also provide opportunities to study how animals move across a novel landscape, and how their movements are influenced by landscape configuration and anthropogenic features. Translocation among populations is considered a potential conservation strategy for lesser prairie-chickens ().

- Incubation breaks are essential for nesting birds but can raise the risk of nest loss; the study focuses on how various factors influence female Lesser Prairie-chickens' nest attentiveness and survival of nests.
- Data from 87 female birds across 109 nests showed that higher nest attentiveness (from 21% to 98%) led to a 39% increase in daily nest survival, but factors like body mass and environmental conditions affected this attentiveness.
- The findings indicate that as climate changes, greater temperatures and extreme weather could negatively impact the nest success of ground-nesting birds, highlighting the need to understand their incubation behavior in changing environments.
The Lesser Prairie-Chicken (Tympanuchus pallidicinctus; LEPC) is an iconic North American prairie grouse, renowned for ornate and spectacular breeding season displays. Unfortunately, the species has disappeared across much of its historical range, with corresponding precipitous declines in contemporary population abundance, largely due to climatic and anthropogenic factors. These declines led to a 2022 US Fish and Wildlife decision to identify and list two distinct population segments (DPSs; i.
