在阳光透过花瓣的瞬间，一只色彩斑斓的蜂鸟正悬停于金黄色的花丛中，尖喙张开，似乎在呼唤着春天的欢愉。这鸟儿的羽毛在光影间闪烁着蓝绿色的光泽，它不仅在捕捉花蜜，也在无意中展示着它求偶的行动。一个意外的细节显露无疑：它的眼睛里流露出几分紧张与坚持。   蜂鸟的情感状态可通过它们的求偶鸣叫进行解读。研究表明，这种鸣叫不仅是为了吸引伴侣，更是蜂鸟自我表达的一部分。科学家发现，求偶的获得绝非仅靠色彩的美丽，更需合适的鸣叫频率——通常在每分钟160到180次的高频率。这种频率不仅能有效吸引异性，还能在竞争中显示出强壮的体格。  ...

  The sight of a humpback whale breaching the surface evokes awe, but it can also lead to a curious question: are they practicing for an aerial circus act? After countless hours observing these magnificent creatures, one can’t help but wonder if they’re just showing off or engaging in a heartfelt game of "who can jump higher." In reality, this behavior offers insights into the...

Dr. Leigh Burkett explains limited ingredient diets for dogs and when they can be beneficial.

Accurately controls terrarium temperatures Ideal for use with Heat Mats and Heat Cables From 20°C up to 35°C (68°F – 95°F) Waterproof remote sensor Controls heating devices up to 100 W/ 300 W Recessed temperature setting to avoid accidental setting or tampering Waterproof remote sensor with 6 foot / 185cm probe cord Red LED heat indicator shows when heating element is ON Can be used with the following Exo Terra heating sources: Heat Mat - Heat Cable - Ceramic Heater Reptiles are ectotherm, and use heat from an external source to thermoregulate their optimal body temperature. Most reptiles use direct radiant heat from the sun in combination with conductive heat from sun-heated surfaces such as branches, rocks or other heat accumulating structures. Providing such an appropriate, species related, temperature gradient in the terrarium is an important factor in successful reptile keeping. With the Exo Terra 100 W/ 300 W Electronic ON/OFF Thermostat you can create a well controlled heating system that allows you to maintain the required temperature conditions similar to those found in a desert or tropical environment. The Thermostat will also help to prevent overheating and undercooling during hot summer days or cold winter nights. The electronic Triac switch keeps the temperature at the desired setpoint with a much higher accuracy compared to conventional thermostats and virtually eliminates temperature swings in the terrarium. Simply connect your Heat Mat, Heat Cable or Ceramic Heater to the Exo Terra ON/OFF Thermostat, set the preferred temperature and place the heat sensor in the desired spot. The Red LED heat indicator will light up when the heating device is ON and will shut off once the desired temperature has been reached. The recessed dial of the thermostat will prevent accidental temperature change if the device is being handled. The waterproof remote sensor can be safely used in highly moist terrariums and aquatic environments. The Exo Terra Thermostat should be set according to the needs of the animals. Thoroughly research the preferred optimum temperature range (POTR) for your specific reptile, so you can create the correct temperature gradients inside the terrarium to allow your reptiles to thermoregulate.
