海绵是珊瑚礁重要的生态和功能成分。最近，一种关于海绵在有机质循环途径中的功能生态学的新假说-海绵-环假说被海绵吸收，并作为碎屑被分流到更高的营养水平，并在浅层(<； 30 m)隐蔽物种中得到了验证。然而，在中层深度(∼ 30-150 m)缺乏对这一假说的支持。在这里，我们研究了海绵循环途径的先决条件--碎屑的产生，在相互移植实验中，使用来自10和50 m水深的Halisarca caerula。与h的浅层样品相比，中生海绵的碎屑产生明显较低。海蓝属。此外，移植海绵中的碎屑产生率与观察到的驻留海绵的碎屑产生率方向一致。这些海绵的微生物群落在浅层和中层之间也有明显的差异，移植海绵的微生物群落在10d内也沿着新的深度方向移动，这主要是由于氧光细菌、酸性微生物、亚硝酸杆菌、亚硝酸螺旋菌、三角洲蛋白细菌和达氏杆菌的变化。这发生在这样一个环境中，在发现这些海绵种群的浅层到中层深度梯度上，溶解和颗粒营养资源的可用性都发生了显着变化。这些结果表明，海绵碎屑产量的变化主要是由营养资源的不同质量和数量以及海绵宿主及其微生物群沿浅层到中层深度梯度的利用所驱动的。
Sponges are important ecological and functional components of coral reefs. Recently, a new hypothesis about the functional ecology of sponges in organic matter recycling pathways, the sponge‐loop hypothesis, in which dissolved and particulate organic matter is taken up by sponges and shunted to higher trophic levels as detritus, has been proposed and demonstrated for shallow (< 30 m) cryptic species. However, support for this hypothesis at mesophotic depths (∼ 30–150 m) is lacking. Here, we examined detritus production, a prerequisite of the sponge loop pathway, in a reciprocal transplant experiment, usingHalisarca caeruleafrom water depths of 10 and 50 m. Detritus production was significantly lower in mesophotic sponges compared to shallow samples ofH. caerulea. Additionally, detritus production rates in transplanted sponges moved in the direction of rates observed for resident conspecifics. The microbiome of these sponge populations was also significantly different between shallow and mesophotic depths, and the microbial communities of the transplanted sponges also shifted in the direction of their new depth in 10 d largely driven by changes inOxyphotobacteria,Acidimicrobiia,Nitrososphaeria,Nitrospira,Deltaproteobacteria, andDadabacteriia. This occurred in an environment where the availability of both dissolved and particulate trophic resources changed significantly across the shallow to mesophotic depth gradient where these sponge populations were found. These results suggest that changes in sponge detritus production are primarily driven by differential quality and quantity of trophic resources, as well as their utilization by the sponge host, and its microbiome, along the shallow to mesophotic depth gradient.
