Active and passive vertical motion of zooplankton in a lake

Zooplankton of Hancağız Dam Lake (Gaziantep - Turkey)

Zooplankton samples were taken seasonally from Hancağız Dam Lake between April 2012- May 2013 period. During the study, a total of 52 species (34 belong to genus Rotifera, 11 to Cladocera and 7 Copepoda) were found in Hancağız Dam Lake.Based on the number of individuals, rotifers were the dominant group in the dam lake (65.4%) followed by Cladocera (21.2%) and Copepoda (13.4%).All of the zoopla...

Pseudo-diel vertical migration in zooplankton: a whole-lake ¹⁵N tracer experiment

Pseudo-diel vertical migration in zooplankton: a whole-lake N tracer experiment

Diel vertical migration (DVM) of zooplankton is commonly considered an adaptation for feeding in food-rich and warm surface waters at night and avoiding visual predators during the day. However, the critical assessment of migration patterns frequently suggests that: (i) zooplankton may leave deeper waters with rich, deepchlorophyll layers and move into the epilimnion where food resources are lo...

a contrastive analysis of concord and head parameter in english and azerbaijani

این پایان نامه به بررسی و مقایسه دو موضوع مطابقه میان فعل و فاعل (از نظر شخص و مشار) و هسته عبارت در دو زبان انگلیسی و آذربایجانی می پردازد. اول رابطه دستوری مطابقه مورد بررسی قرار می گیرد. مطابقه به این معناست که فعل مفرد به همراه فاعل مفرد و فعل جمع به همراه فاعل جمع می آید. در انگلیسی تمام افعال، بجز فعل بودن (to be) از نظر شمار با فاعلشان فقط در سوم شخص مفرد و در زمان حال مطابقت نشان میدهند...

Active versus passive processing of biological motion.

Johansson's point-light walker figures remain one of the most powerful and convincing examples of the role that motion can play in the perception of form (Johansson, 1973 Perception & Psychophysics 14 201 - 211; 1975 Scientific American 232(6) 76 - 88). In the current work, we use a dual-task paradigm to explore the role of attention in the processing of such stimuli. In two experiments we find...
