Workload and assignments

Work types reported in BruinWalk reviews of this course, across recorded instructors and terms. They may differ from this term's syllabus.

dibs has not read this course’s reviews, so it cannot say what kind of work it sets. That is dibs not having looked. It is not a course without papers or exams, and the reviews linked below are the answer until dibs catches up.

What comes first

The chain dibs can see is 2 courses long before EE BIOL 161L. dibs has read a class page for every course in it.

Counted in courses rather than quarters: dibs does not know which of them a department lets you take together.

From the registrar's catalog

Laboratory, four hours. Requisites: course 161 (may be taken concurrently), Life Sciences 7B. Introduction to foundational principles, theory, and field application of ecology. Emphasis on ecology of terrestrial plants, use of these principles to predict consequences, and uncertainties associated with human-caused changes in environment. Examination of both biotic and abiotic elements of environment that influence distribution and abundance of plant species. Includes range of activities, from observations of plant materials in laboratory and in UCLA botanical garden, to manipulative greenhouse experiments with fast growing annual plants, to computer-based explorations of dynamics of foundational ecological models. Letter grading.

Seats over time in Fall 2026

How each lecture has filled since dibs first saw it. This course runs 2 lectures; the legend under the chart picks one.

A dot is a reading where something moved: the seat count, the status, or the waitlist.

What a flat run means, and where a line starts

Flat between dots means it did not drift, it held and then jumped, and a line starts when dibs first saw that lecture rather than reaching back before it existed. A lecture that has never moved draws a flat line across the whole window, and one with two or three readings draws a line joining them, which is too few to read a trend from.

Seats from 18 Aug 21:40 to 2 Oct 05:22, 9 to 14. dibs read 168 of the 530 hours its hourly record here covers, 32%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 362 hours dibs was keeping a record and did not reach this section. Nothing before 10 September at 04:00, where this section's record starts, has a read either way, which is 535 hours of this window. Where the drawing is faint or broken, that never means the readings are doubtful. It means the stretch between them is unaccounted for.

How readings and alerts work

A reading and an hourly record are different things, and most charts here hold more of the second missing than present. dibs has taken readings of a section since long before it began keeping an hour-by-hour log of when it looked, so the empty stretches are dibs saying it was not keeping that log yet, not that it looked and found nothing. That is the age of the record and not a fault.

Seat counts show the last successful read, not live availability. Refreshes can be delayed by request limits or upstream interruptions. Watched sections receive priority, but an hourly update for every section is not guaranteed.

The registrar can change a seat count between our checks. Alerts depend on dibs detecting an opening and completing delivery; a quiet watch does not prove that no seat opened. Check the registrar before enrolling.
