Edited at 2024-01-29 14:36:54This Valentine's Day brand marketing handbook provides businesses with five practical models, covering everything from creating offline experiences to driving online engagement. Whether you're a shopping mall, restaurant, or online brand, you'll find a suitable strategy: each model includes clear objectives and industry-specific guidelines, helping brands transform traffic into real sales and lasting emotional connections during this romantic season.
This Valentine's Day map illustrates love through 30 romantic possibilities, from the vintage charm of "handwritten love letters" to the urban landscape of "rooftop sunsets," from the tactile experience of a "pottery workshop" to the leisurely moments of "wine tasting at a vineyard"—offering a unique sense of occasion for every couple. Whether it's cozy, experiential, or luxurious, love always finds the most fitting expression. May you all find the perfect atmosphere for your love story.
The ice hockey schedule for the Milano Cortina 2026 Winter Olympics, featuring preliminary rounds, quarterfinals, and medal matches for both men's and women's tournaments from February 5–22. All game times are listed in Eastern Standard Time (EST).

Communities and their succession
community structure
community species composition
(Difference between different communities) The most important characteristic: species composition
The number of species in a community is called species richness
Features: Changes with time and environment
Dominant populations: Not only are they numerous, but they also have a great impact on other species in the community and often dominate.
interspecific relationships
Original collaboration
Mutualism
prey
parasitic
interspecific competition
Pay attention to image recognition
The spatial structure of the community
vertical structure
The layering of plants is related to the use of light
Significantly improve resource utilization
Create a variety of habitat spaces and food conditions for animals
horizontal structure
terrain changes
soil moisture
Salinity
Different light intensity
own characteristics
Influencing factors such as humans and animals
community seasonality
ecological niche
Defining the status and role of a species in a community includes its spatial location, resource occupancy, and relationship with other species, which is called the ecological niche of a species.
A relatively stable ecological niche is conducive to resource utilization. It is the result of co-evolution between species in the community and between organisms and the environment.
Introducing the concept: coevolution
Main types of communities
desert biome
grassland ecological community
forest biome
community succession
Definition: The process by which one community is replaced by another community over time is called community succession.
Succession type
bare rock stage
lichen stage
moss stage
herbal stage
bush stage
Arbor stage
succession
primary succession
secondary succession
Black inscription: The population that adapts to changes increases or is maintained, while the population that does not adapt decreases or is even eliminated.
The impact of human activities on community succession
Definition: A collection of various biological populations that gather in a certain area at the same time is called a biological community, or community for short.

Ecosystems and their stability
ecosystem structure
scope
Ecosystem definition: In a certain space, there are biological communities and their abiotic environment that interact to form a unified whole, called an ecosystem.
Ecosystems have a certain structure
components of an ecosystem
nonliving matter and energy
producer
The foundation of the ecosystem
Conversion of solar energy into chemical energy stored in organic matter through photosynthesis.
consumer
Accelerate the material cycle of the ecosystem while helping plant pollination and seed dispersal
decomposer
Decompose animal and plant remains and animal excrement into inorganic matter
food chain food web
Food chains are intertwined and connected into complex nutritional relationships, which is the food web
energy flow in ecosystems
Boldface: The process of energy input, transfer, transformation and dissipation in the ecosystem is called the energy flow of the ecosystem
