An electric fish generates an electric field using an electric organ, modified from muscles in its tail. The field is called weak if it is only enough to detect prey, and strong if it is powerful enough to stun or kill. The field may be in brief pulses, as in the elephantfishes, or a continuous wave, as in the knifefishes.
As almost all electric cars have regenerative braking brake pads can be used less frequently than in non-electric cars, and may thus sometimes produce less particulate pollution than brakes in non-electric cars. [9] [10] Also, some electric cars may have a combination of drum brakes and disc brakes, and drum brakes are known to cause less ...
Climate change also interacts with other drivers of poor mental health, such as conflict and forced migration. [66] The slower changes caused by climate change, such as damages to land use and ecosystems, also have the potential to lead to mental health consequences. Access to and engagement with natural spaces has a positive effect on mental ...
Furthermore, climate change may disrupt the ecology among interacting species, via changes on behaviour and phenology, or via climate niche mismatch. [9] The disruption of species-species associations is a potential consequence of climate-driven movements of each individual species in opposite directions.
Electric organ discharges are two types, pulse and wave, and vary both by species and by function. Electric fish have evolved many specialised behaviours. The predatory African sharptooth catfish eavesdrops on its weakly electric mormyrid prey to locate it when hunting, driving the prey fish to develop electric signals that are harder to detect.
Climate activists and some lawmakers have long said cutting emissions in transportation has to go well beyond people embracing electric vehicles and adopting California-style clean car rules that ...
For example, a horse can sniff the air to detect pheromones but a fish which is surrounded by water will need a different method to detect chemicals. Aquatic animals can communicate through various signal modalities including visual, auditory, tactile, chemical and electrical signals. Communication using any of these forms requires specialised ...
Additionally, a recent survey from the Public Policy Institute of California found that climate change is the most important environmental issue to Californians with 82% being concerned that ...
