A new nationwide study from the Hebrew University of Jerusalem uncovers the Israeli public’s conflicting attitudes toward free-roaming cats. While nearly a third of respondents regularly feed stray cats, a large majority still support reducing their numbers. This contradiction highlights the complexity of public attitudes, where emotional actions coexist with ecological concerns. Researchers emphasize the need for public education and propose involving cat feeders in monitoring and control efforts to improve policy effectiveness.

More female athletes believe it is fair (43%), rather than unfair (36%) for athletes with a DSD – difference in sex development - to be included in the female category for contact sports like rugby and non-contact sports reliant on physical capacity like sprinting, a new study shows.

The study also found that a majority of athletes believe it is unethical to require athletes with a difference in sex development to medicate for eligibility.

The researchers say that athletics governing bodies should use this new data on athletes’ views to update their eligibility policies.

DSD stands for difference in sex development.  People with a DSD do not always develop along typical male-female lines. Their hormones, genes, reproductive organs may be a mix of male and female characteristics.  The most high-profile athlete with a DSD is South African runner Caster Semenya.

New findings challenge assumptions about species’ ability to persist under climate change. Following a nine-year study of over 100,000 individual Drummond's rockcress plants – a common plant found in mountains across North America – researchers reveal that climate change is outpacing natural gene flow, threatening population survival even within a broadly distributed plant species’ native range. The findings highlight the potential role of assisted gene flow in plant conservation. Climate change is rapidly altering where species can survive and thrive. While many plant and animal species span broad geographic areas, their populations are often finely tuned to the specific climate of their local environments. This local adaptation means each population may tolerate only a narrow slice of the climate conditions the full species can endure. Evolutionary processes, including genetic variation, rapid adaptation, and gene flow, have the potential to dramatically alter population persistence under climate change – a process known as evolutionary rescue. However, these factors are rarely integrated into ecological models that predict how species will respond to climate change.

Using Drummond's rockcress (Boechera stricta), a widely-distributed, short-lived mountain plant in the mustard family, Jill Anderson and colleagues investigated how plants may adapt – or not – to a rapidly changing climate. In a nine-year-long field experiment in Colorado, Anderson et al. planted more than 102,000 individual plants across a range of elevations and manipulated snowpack to mimic climate variation. By integrating the genomic and fitness data into evolutionary demographic models under preindustrial, current, and projected climates, the authors found that climate change increases extinction risk for locally adapted populations by eroding their genetic advantages and outpacing natural gene flow. This was true across all elevations and not just at the warmest range edges. According to the findings, the direction of gene flow in adapting species is crucial. For example, in some mountain species, gene flow predominantly moves downhill, which may hinder the ability of populations to adapt to warming conditions at higher elevations. Compounding this challenge, the pace of climate change is outstripping the capacity of many species to shift their ranges upslope. Anderson et al. note that assisted gene flow – deliberately moving pre-adapted individuals to new locations – could help maintain genetic diversity and species persistence but must be carefully managed. “The lessons from Anderson et al. are sobering with respect to the ability of natural populations to adapt to, and persist under, rapid global warming,” writes Sally Aitkin in a related Perspective. “Although the capacity for persistence will vary among species and with life history traits, populations cannot persist simply because their locations remain within the overall range of climatic tolerances for that species as a whole.”
